Historical Context

 * Note: The characters within the story rarely describe historical events within helpful context, so the unit BA, “Before Arrival”, and AA, “After Arrival”, will be used to place moments in time with the best available knowledge. Both are in reference to Natsuki Subaru’s arrival in the new world. In this case, only BA will be used. Also, note that the units are not official.

The Great Calamity (大災厄 Daisaiyaku): See Great Calamity

A critical event in the Re: Zero world that occurs approximately 400 BA, or 400 years before Natsuki Subaru is summoned to the new world, in which the Witch of Envy first appears. Her rampage results in her almost destroying the world and is subsequently fought and sealed by the Sage, the first Sword Saint, the Dragon and the Sage's apprentice.

Silver Flower Dance of Picoutatte (銀華乱舞): Two notable duels taking place in the city of Picoutatte between the Sword Demon Wilhelm van Astrea and the Vollachia's strongest warrior, Eight-Arms Kurgan, roughly four decades before the start of the main series. During their first duel, both of the men were fighting on behalf of their respective countries–Wilhelm fought for the Dragon Kingdom of Lugnica, and Kurgan fought for the Sacred Empire of Vollachia. The duel ended in a draw, as Stride Vollachia intervened in the fight after Kurgan shattered Wilhelm's right half of his body, and Wilhelm cut off one of Kurgan's arm;Stride did not want to lose his bodyguard just yet. Their second duel took place roughly 3-4 months after their initial duel, in the very same city. This time, however, the duel ended with Wilhelm destroying one of Kurgan's four Demon Cleavers and inflicted mortal wounds all over his chest, leaving him to bleed out–which he would have, if the Divine Dragon wouldn't heal him, after ascending upon the city.

Subjugation of the Evil Dragon: See The Subjugation of the Evil Dragon

An event, taking place roughly a year after the end of the Demi-Human War and 3-4 months after the first Silver Flower Dance of Picoutatte. It is widely regarded as one of the worst days in the Kingdom's history. On one faitful day, Stride Vollachia, along with his subordinates–two Shinobi, Twin Shura, the sole survivor of the Evil Eye Tribe, Ashen Bride and the Vollachia's strongest warrior, Eight Arms–and the kidnapped Sword Saint, made his appearance in one of the five regional capitals–Picoutatte. They kidnapped and killed twenty civilians who bore a Divine Protection and summoned the Black Dragon Valgren. During the nighmarish battle, hundreds of civilians and soldiers from the Subjugation Squad lost their lives and the majority of the city was utterly destroyed. At the end, the Kingdom managed to break the Magical Circles preventing any distubrance with the outside world. In accordance to his covenant with the Dragon Kingdom of Lugnica, the Diving Dragon descended over Picoutatte, purifying Valgren into nothing more than a pile of ash, healing the numerous wounded and exstiquishing the fires burning throughout the city. Despite the gravity of the attack, the casualities were less than a third of what they anticipated.

Silver Flower Dance of the Sword Saint and the Blue Lightning: A duel between Lugnica's Sword Saint Reinhard van Astrea and Vollachia's 1st ranking Divine General Cecilus Segmunt. Roughly half a year before the start of the Royal Selection, Vollachia's strongest individual Cecilus Segmunt uninvitely showed up the Dragon Kingdom of Lugnica, in search of the Sword Saint, requesting a rematch. The duo were allowed to have a proxy duel with both of them representing their respective countries. In front of the Training Ground Arena chalk-full of knights, Reinhard drew the Dragon Sword Reid for the 3rd time in his life. Both survived the duel but the winner is unknown.

The Day of Red Earth and Sky: See Re:Zero Prequel: Bond of Ice Seven years before the main story, Puck unfroze Emilia from the ice she was imprisoned in. It was only a half year later in 6 BA when Melakuera, the Great Spirit of Fire, came in contact with the former two, and acted in accordance with his beliefs. Stating that Emilia was a threat to the equilibrium of the world, Melakuera decided to exterminate her due to being a "Witch". However, Puck couldn't allow the former to happen, thus he decided to fight him. Ultimately, Elior Forest became the battleground of Melakuera and Puck's clash, with the latter being the victor of that battle. That day became infamously known across Lugnica as the "Day of Red Earth and Sky".

Demi-human War (亜人戦争): See Demi-Human War

The civil conflict between Demi-humans and Humans within the Kingdom of Lugnica taking place from 50 to 41 BA. Human victory due in part to Theresia van Astrea, the previous Sword Saint (or Reinhard's grandma}.

The Great Expedition: See Great Expedition

The first Hakugei(White Whale) hunt led by the previous Sword Saint in 14 BA. Disastrous as a result of Theresia losing her blessings to Reinhard partway through the battle and getting killed.

Lion King (獅子王): A sage king whose uncanny intuition and leadership guided Lugnica to prosperity in the distant past before the contract between the Lugnica family and the dragon Volcanica which guaranteed the health and the security of the nation from external threats. Once the established country became known as the Dragon Kingdom of Lugnica and the royal family's coat of arms shifted from a symbol of the “lion” to that of the dragon. The former insignia came to pass over to House Karsten instead. Since then, the royal family had only needed to carry the bloodline to ensure the contract. While the de jure-wise wielded the highest authority in the land, due to their lacking statesmanship since then, their influence over state matters has waned from the days of the "Lion Kings". The effects of that led the general populace to look to the dragon and the Council of Elders more often than they would have otherwise for guidance instead. Every now and then a royal heir bearing the potential qualities to be the next "Lion King" would be born; unfortunately, every known person with the royal bloodline is now dead.

Races
Elf (エルフ): Elves are a race of Demi-humans known for their longevity and beauty. Because of the Witch of Envy, Elves were also the target of prejudice from others. Currently, the only known elven community to appear in the story is frozen in the Great Elior Forest.

Oni (鬼): Among the numerous humanoid races that existed in the world, the Oni were considered the mightiest. Their powerful bodies and the potency of the mana quality they employed, both granted the Oni peerless combat strength. However, as the members of the race had a elitist mindset, in order to preserve their purity and pride, enacted strict taboos and lived in villages in the mountains, away from others. Accordingly, the number of Oni was always low. The few Oni settlements tended to be small rural villages located in mountain ranges that adhered to a strong Social Darwinist and isolationist way of life. The only visible physical difference between a Oni and human were a pair of long curved-horns that sprouted from the forehead of an Oni, when their lives were in danger. The horns would absorb mana from the atmosphere, greatly increasing an Oni's physical and magical capabilities. Twin demons were usually only born with one smaller horn each, thus making them weaker than their two-horned kin. There do exist those with only one or even no horns the latter which are known as Hornless, and were considered the dregs of their society because of it. Moreover, Oni born that way were to be killed by tradition to protect the Oni pride as a powerful and nearly perfect species. The village Ram and Rem lived in 10 years prior to the main story was the last Oni village, effectively making them the only two Oni left in the entire world. Roswaal remarked that the Oni's demise was because of natural selection, as they refused to accept new ideas, and not because of discrimination or prejudice.

Giant (巨人): Giants are a Demi-human race of massive people with tremendous strength and a lifespan of around 150 years. They fought in various places during wartime and because of that their numbers had dwindled. Currently, the only Giant in the royal capital is Rom. It is mentioned that Sekhmet killed almost all Giants.

Evil Eye Tribe (魔眼族): The Evil Eye Tribe are a type of Demi-Humans that were wiped out by the Empire. There were originally not that many of them and they possessed the ability to see invisible things and interfere with the minds of others with their eyes. Rumours say that there are still living members existing. In fact, throughout the story, there have been quite a few Evil Eye members that have made their appearance, namely in the side stories.

Wolfin Tribe (ウルフェン族): The Wolfin Tribe are a rare type of Demi-human who are at the brink of extinction. There is an anecdote about the Wolfins being raised to refer to themselves as Kobolds.

Dwarf Tribe (小人族): The Dwarf Tribe are a common type of Demi-human that are shorter than normal humans.

Boar Tribe (イノシシ族): The Boar Tribe were usually an uncommon race of Demi-human, but due to the Demi-human War and the Sword Saint nearly wipping out their existence, their kind are now rarely seen. They're about the same size as the Wolfin Tribe. They have a head of a boar with a human physique.

Multi-Arm Clan: A once nomadic race who finally settled down in the Vollachia Empire decades ago. They are few in number and with exception of Kurgan typically have 4-5 arms.

Steelfolk: The Steelfolk are a special type of race, unlike other races. They're rarely seen on the surface as they mostly travel underground. They're made out of robotic machinery and have artificial life, so they couldn't emit emotions or feel pain, however, the one thing they couldn't develop was their speech as they speak in broken English. Their limbs and body parts can detach and reattach, and even heal themselves as long their heart and brain remained intact.

Insect Cage Clan: The Insect Cage Clan is a minority group of various demi-humans, existing only on the Vollachian soil. The clan consists of different demi-human races who–at a young age–ingested a special type of insect with magical properties, allowing them to eventually adopt their powers. The individual's Od syncs with the insect's Od, allowing them to share their souls, merging them into a single living being. By doing so, the person's external appearance drastically changes into that of a bug, giving them a gruesome appearance most people fear, but most importantly, a means of attacking. They're encased in a bug's shell that can easily deflect powerful attacks, have wings that allow them to skillfully maneuver around the battlespace and long hardened limbs which resemble a sickle. Known throughout the Empire for their deadliness and effectiveness, the Insect Cage Clan has no shortage of unique and special attacks which cause most–if not all–warriors a very tough time. Coupled with their large numbers, they're very effective assassins for dispatching groups of powerful foes threatening the Emperor.

Sudrak Tribe: A clan located deep in the Buddheim Jungle. It's a purely female-born race. The clan's people are known for being descendants of war gods who lived in the jungle for hundreds of years. They reproduce with men from the outside. Members of this clan are dark skinned and have pitch black hair, similar to Subaru's. As expected from a warrior clan, the Sudrakians have mastered the art of guerrilla warfare, using the terrain to their favour, dispatching their targets with poisonous arrows, deadly precision and devastating traps. According to Vincent Vollachia, the Clan was once saved from a predicament by a Vollachian Emperor.

Abilities
Magic (魔法): See Magic.

Authority (権能): See Authority.

Witch Factors (魔女因子): Witch Factors are special, abstract factors that enable people to use authorities.

Divine Protection (加護): See Divine Protection.

Spirit Arts (精霊術): Spirit magic is a type of craft similar to magic that Spirit users employ.

Spirit User (精霊使い): Spirit users, such as Emilia, are people that are contracted with Spirits, and use them in various situations. There are three different classes of Spirits; Minute Spirits (微精霊 Biseirei), Quasi Spirits (準精霊 Junseirei), and Spirits (精霊 Seirei). There are also man made Spirits known as Artificial Spirits (人工精霊 Jinkou Seirei) which were created by the witch Echidna. Unlike Magic users, Spirit Users gather mana from outside their body. The only downside to Spirit Users is that the greatest amount of mana they can use at one time, is dictated by their contracted spirit. The greater the spirit's capacity for mana, the bigger the spells its contractor can cast.

Curse: A subcategory of spiritual and magical arts that originated from the country of Gusteko. The most notable traits about curses are they cannot be defended against once activated and they are the most effective class of magic when it comes to killing. However physical contract between the caster and target is mandatory for curses to work. Furthermore, unlike other normal magic, Curses are only limited to taking lives and have no other application in society beyond that. This caused the practice to become taboo leading it to fall out of favor among mainstream Magicians. Incidentally, there are Demon Beasts such as Wolgarm who are capable of inflicting curse spells through their bites and draining mana of the victim.
 * Curse Doll (呪い人形): Curse Doll is a curse which involves the user carving a curse mark that includes the information of the target they want to kill on someone, and upon activation, the person with the curse mark gains immortality, but as a cost they lose their sense of self and can't do anything else but kill the target and they die when the target is killed. Also, there seems to be a limit on the immortality. However, there's supposedly a way to cast the curse without the person losing their sense of self, which is what happened to Elsa, though repeatedly dying turned her into a curse doll.

Wall Strike (壁当て): A combat skill where, by controlling the mana inside the body, a shockwave is produced that can pass through obstacles.

Soul Transference: It is a lost forbidden magic art that allows a person to move their spirit from one body to another by over-writing the soul of the target body with their own. By doing this over and over to extend their life indefinitely, the user can achieve what Beatrice termed as "subjective immortally". However it has one major restriction in that for it to work, the person whose soul is overwritten must be of blood-relation to the caster. The spell was originally created by Echidna to gain immortality, but she could not complete it before falling at hands of the Witch of Envy. Instead, it was finished by Roswaal who had been using it to survive until the present era.

Magic Circle: A type of geometric magic algorithm used to perform complex spells and rituals that can be drawn on the earth or a living being. These can produce great kinds of effects such as large-scale magic that completely alters the state of a battlefield, imbuing an individual with extreme power, or even temporarily cutting off Divine Protections. However "Magic Circles" drawn on the ground once found can have their spells be disputed and the range of the effects of the magic only extent as far the circle's physical range so hiding them until activate is necessary. Since this is ancient magic very few people know about it and even fewer are capable of using it. Magic Circles were deployed frequently by demi-humans during the civil war.

Dragon Kingdom of Lugnica
Council of Elders: An advisory board that supports Lugnica's ruler comprised of accomplished and distinguished people. They are currently administrating the country in place of a king until the Royal Selection is over.

The Brotherhood (同胞団 Douhou-dan): An organization that was led by Marcos Gildark 15 years before Natsuki Subaru was summoned into the world. The organization was created to fight against the class-discrimination that was occurring in the Royal Capital at the time.

The Golden Wing Faction (金翼党 Kinyoku-tou): An organization that was led by Fareed Impusen 15 years before Natsuki Subaru was summoned into the world. The organization was created by nobles who lacked a sense of purpose because they were born as third and fourth sons, and the like, thus failing to inherit major duties in their lineage. The organization acted as a vigilante group to quash crime in the Royal Capital.

The Three Heads: A term used for the three most powerful groups of Flanders underground society known as the black society.
 * The Libra (天秤): A faction that's part of the Three Heads, led by Manfred Madison also known as "The Tattooed Face" and are in charge with gambling. The Libra also seem to revere the Witch of Pride.

Magic Related
Od Laguna (オド・ラグナ): Od Laguna–often referred to as the "world" in layman terms–is a vast storage of mana located at the origin of the world itself, or in other words, at the world's core. It is where all mana comes from in the world, a eventually goes back to. No one knows where it is located and the Author once state that it's an entity similar to the Sun, as it has no will of it's own. It is said that those who stumble over prohibited arts have had their spirits destroyed by simply looking at it. Some speculate that it is the world's will and gives Divine Protections to people. Its main function is to provide stability to the world and its inhabitants by regulating mana, souls and other aspects of life, while limiting the frequency of natural disasters that occur due to mana oftentimes running short. Mana flows from Od Laguna to every individual's Od, which is connected to it via their gate. How much one receives depends on the size of the gate, e.g the bigger it is the more mana they get, which also affects their aptitude for magic. When mana is expelled from an "Od" through the individual's gate, it can be used to either create magic or power objects such as Lagmites. Once spent, the residue mana lingers around, becoming atmospheric mana, which Spirits and Spirit Art Users can harness. Eventually, the atmospheric mana returns back to Od Laguna, restarting the cycle again, for all eternity. While Od Laguna does not necessarily possess a physical form, the Author has claimed that Reinhard would be able to defeat/destroy it, if he was ordered to.
 * Hall of Memories: A vast endless white space within Od Laguna, where souls of the dead go to get filtered of their impurities, or in other words, the memories of its previous life, before they get reused. Those memories in turn are then recorded & preserved by turning them into Books of the Dead, which are stored in the Pleiades Watchtower's library.

Mana: Mana is a type of colourless supernatural energy that exists in the atmosphere which can be found basically everywhere. When magic is being processed, a person's innate attitude will charge the mana particles to their specific “element”, which briefly manifests as formless spell-form before taking shape of the spell chosen. When a person casts magic, they will experience brief physical and mental fatigue which results in sudden weakness if they are not used to expelling magic or if they overcast beyond their capacity. Mana is also used in martial techniques and special abilities such as beastification, making superhuman feats possible, although beastification is often used by individuals who are not very proficient in using magic directly. Mana itself originates from the Od Laguna, the world's Od.

Gate: An invisible portal-like apparatus that exists in every living thing. It allows mana to pass through the body and be stored in the Od. Whether one can use magic or not entirely depends on its condition; be it either fully or partly open. Most people only have partly functioning gates so magic is out of reach to them. In addition, there are some with a defective gate that keeps them from releasing mana at all. Overcasting magic can also lead to damaging the gate, and then the permanent loss of magic if the user continues to do so without treatment. However, that is difficult to obtain and if the gate breaks before that then nothing can be done.

Od (オド): Od is life energy that dwells inside of a living being from birth, making it the opposite of mana, which is magical energy that exists in the environment. It varies from person to person in terms of quantity and size which represents the lifespan of an individual. It serves also acts as a vessel for storing mana that flows through the gate from the environment, so having a large capacity is especially beneficial to those who can use magic. Od can be used in place of mana to cast magic, however unlike mana, using Od is like using your own lifespan, and so it isn't recommended outside of emergencies. Under special conditions, an individual is able to encase themselves in their own Od which will act as some sort of a separate world that is even free from the influence of Authorities. During the events of Arc 5, Anastasia Hoshin used this technique to avoid the consequences of the Authority of Gluttony in order to not forget her knight Julius Juukulius.

Defective Gate: A medical term for individuals whose Gate cannot perform the normal circulation process of either absorbing or expelling mana throughout. If the former occurs that person cannot use magic unless they expend their Od. If the latter, then they are at risk of "Mana Poisoning".

Mana Poisoning: Mana Poisoning is a state in which an individual continues to absorb an excess amount of mana beyond their capacity, but is incapable of releasing it, which will eventually destroy their Od and kill them. Improperly configured or defective gates can also bring about this. Individuals in this status who don't receive constant treatment are often very sick.

Magic Release Period (発魔期, Hatsumaki): A phenomenon that occurs to individuals and beings who possess potent magical power, powerful gates and Od that allow them to draw-in and store more mana than they let out. It happens when a magic user doesn't maintain a proper release cycle to let off excess mana from their Od which causes it to overflow from beyond their bodies. It can have drastic effects on the person such as mana poisoning, and it can even affect the environment. The mana will eventually burst out of and damage their gate if it's not forcibly released and released from within them.

Oaths: In the world Re:Zero, there exist concepts known as contracts that can either be magically binding or honour-binding. They are collectively known as oaths, which are broken down into three main categories.
 * Pacts/Contracts: Two parties can form oaths, which are usually made between spirit-sensitive humans or Demi-Humans, and Spirits. By doing this, the formerly mentioned parties form a symbiotic relationship with Spirits, and become what is known as a Spirit Art Users.
 * Covenants: Covenants are oaths formed between entire bloodlines, rather than just specific individuals, such as the one between the Kingdom of Lugnica's late Royal Family and the Divine Dragon, which vows the Dragon to aid the Kingdom when in need. Covenants are usually long-lasting (for several generations).
 * Vows: Oaths that either binding two individuals or a single party. They can be magically backed, or simply honour-based promises or agreements.

Witch's Miasma: Also sometimes called the "Witch's Scent", is invisible contamination mana that exudes from those who hold the power of witches or are connected to them. The Witches of Sin, the Sin Archbishops of the Witch Cult, Demon Beasts and to a smaller extent low-ranking cult members are prominent examples of this. While the criteria for it aren't known, this miasma can be sensed by certain individuals who are sensitive to it. The miasma is normally harmless when it is in small doses, however in high density it will start having negative effects on all things; living beings with gates will be driven into madness, food will be polluted and go on to corrupt those who eat it. Demon Beasts are attracted to those who give it off and will deliberately attack them as well as grow stronger in places where it is very prevalent.

Lagmite: Alternatively known as mana stones & crystals. They are created when atmospheric mana crystallizes under specific conditions over a period of time. Magic crystals are a large type of mana stones that grow over a significant amount of time and have no impurities, but very few currently exist. With the exception of one, they come in six elements and serve many practical functions in society. I.e fire lagmite can be used in mechanisms for cooking, heating baths or lamps. Earth types are used for strengthening structures like pots or buildings. Light & shadow lagmites are often made use of in powering meteor devices. Any living being that has a "gate" can come in contact and use them. The individual does not need to be able to use magic themselves to make use of them. Crystals in raw form are volatile and need to be handled with care otherwise their will unleashed mana stored within with explosive effects.
 * Pyroxene Crystal (輝石結晶): A rare colourless type of lagmite crystal that unlike a normal mana crystal is very small. They are only found in a place that has a high density of mana. The crystal has been demonstrated to hold incredible powers such as being able to store souls, spirits and fragments of one's Od. In addition to that, it can be used as a means of containing and controlling magical algorithms that generate spells. It often functions as a kind of key for people to pass into places that are otherwise very difficult or impossible due to powerful barriers.

Surplus Mana Circulation Constitution: Words that Ezzo used to describe the physical constitution/make-up which could absorb mana without using Reinhard's technique.

Magical Books: Magical Books are books which can only be read by individuals who are well versed in magic, and can utilise mana. The books look plain on the outside and have blank pages, however, if the reader concentrates, letters made out of mana appear, allowing the holder of the book to read it. According to Beatrice, Echidna had an infinite amount of Magical Books stored in her library.

Story Specific
Gospel (福音): A black book that lists the holder's future. The information is more detailed if the miscalculation between the holder and the world memory is low.


 * Book of Wisdom (叡智の書): The Book of Wisdom is a white book crafted by Echidna that allows her to draw knowledge from the world's memory. The mind of an ordinary person attempting to read it would be fried by the sheer amount of knowledge flowing into the reader's mind.
 * Roswaal and Beatrice's Books of Wisdom (ロズワールとベアトリスの叡智の書):Beatrice's Gospel ep.32.png Two complete gospel books created by Echidna for Roswaal and Beatrice.

Dragon's Blood/Dragon Vein: Blood taken from a Dragon, which acts as a miracle agent. It's said that's capable of curing any disease and even reversing famine instantly. Only the rulers of the Kingdom of Lugnica have access to it. In order to receive it, however, one must kill a Dragon and collect the blood from its last heartbeat. In Volume 26, it is noted that the Dragon Blood stored away in the Royal Castle doesn't belong to the Divine Dragon Volcanica, but rather, to a different Dragon which was as powerful as Volcanica.

Trials of the Tomb (試練): The trials are three different events that take place at Echidna's Grave at night and clearing them releases the barrier on the Sanctuary.

The effects are stronger the more the person is talented.
 * The First Trial (第一の試練): The beginning phrase is "First off, face your past". The trial taker is shown their past and told to get rid of any regret by either accepting or rejecting their past.

These include E・M・B (Emilia-tan Maji Bosatsu), E・M・F (Emilia-tan Maji Fairy), E・M・H (Emilia-tan Maji Healer), E・M・K (Emilia-tan Maji Kishidou), E・M・K (Emilia-tan Maji Koakuma), E・M・M (Emilia-tan Maji Megami), and E・M・T (Emilia-tan Maji Tenshi).

Hornless (ツノナシ): A term for Oni who either have lost their horns or were born without them and Demon Beasts who have been tamed by theirs broken. For the former in this state, they cannot draw-in mana from the atmosphere nor sustain the use of it for long periods resulting in a weakened constitution. However they can survive with regular mana infusion from someone who knows the skill.

Sword Slave: A term for gladiators in Vollachia who fight in deathmatches to entertain the citizens.

Hyena (ハイエナ): In the Kararagi City States, this term is used to refer to people or demi-humans who have no home or anything to eat. They live life by scavenging in trash cans for things to eat. The term is thought to originate from Hoshin's time. Before she was taken from the streets, Anastasia Hoshin lived as a hyena.

Lolicon: A term that was used in Kararagi between Chuden and Ricardo in Anastasia's Kararagi Merchant Path, by the latter after the former mentioned it was "love at first sight" that brought Anastasia to him. The term was coined by Hoshin of the Wilderness 400 years ago and has become a common word in Kararagi since. Some theorize that Hoshin was a lolicon himself.

Apostle of Greed: A term and position given to those who have gained Echidna's favor. It grants them the "Command Authority" which forces compulsory obedience from all replicas of Lewes/Ryuzu. There have been only 3 people who have held this title Garfiel, Emilia and lastly Subaru, however in the case of Subaru he lost that right near the end of the 4th arc.

Demi-human: The general term for all humanoid species such as Beast-humans, Oni, Giants, Elves, various Reptilian races etc. They are found throughout the world, though some are unique to specific regions. Although their social status and treatment vary by country with Gusteko being the worst. Half elves and similar mixed-bloods are particularly detested due to the similarities of their birth with the Witch of Envy which has extended to demi-humankind in general to a lesser degree.

Dragon Maiden: A position and title which will be given to the woman who wins the Royal Selection and becomes Luginca's ruler. Dragon Maidens have existed in the past, but back then they served only as intermediaries between the previous kings and Volcanica as part of the old contract.

According to the legends, Evil Dragons were all but exterminated by the first Sword Saint Reid Astrea, four centuries ago.

Worldbuilding
Consistencies include...


 * Kingdom of Lugnica National Foundation Day (ルグニカ王国の建国記念日): The 25th of the month Marshba (マルシュバ) of Laguna's history. Coincides with the Monthly Festival (月祝祭): Also on the 25th day of every month. Unsurprisingly, it is a monthly morning event celebrating the national anniversary of Lugnica.


 * Months: The world of Re:Zero has its own months, but only four are known so far in the story, "Tadmus", "Arbe", "Marshba" and Kisdam".


 * Seasons (季節): The seasons in the world are categorized into “Red-Sun, Blue-Sun, Yellow-Sun, and Green-Sun”, with each matching a different elemental magic type. According to Subaru, Red-sun refers to the equivalent of Summer, Blue-sun to Winter, Yellow-Sun to Autumn and Green-Sun to spring.


 * Time Tower (刻限塔) and by extension, Time: Time Towers are tall buildings with a time crystal placed in them, similar to a clocktower. Many cities and villages have them and multiple towers are placed within each one. The clock and Time, in general, are split into two phases, Brightsun and Darksun, which represent the elements of light and shadow. These are further divided into sub-section sections that correspond to the 4 primary elements with each representing 6 hours. Brightsun is Wind Time and Fire Time, ranging from 6:00 AM to 6:00 PM. Darksun is Water Time and Earth Time ranging from 6:00 PM to 6:00 AM. The crystals wane and glow with the passage of time to show the transition.

Facets of background politics within the Re:Zero world include...


 * Royal Selection (王選): See Royal Selection.

An election to decide on who will become the 42nd King of Lugnica. The elections span for three years until the same day, which falls on the month before the ritual to form a new contract between Volcanica and the chosen candidate. The five candidates are Emilia, Crusch Karsten, Anastasia Hoshin, Priscilla Barielle, and Felt, all of whom were chosen by the Dragon Insignias. For a more detailed explanation, see Royal Selection.


 * Divine Dragon Ritual (神龍儀): A ritual between Volcanica and either the king or a shrine maiden of the Kingdom of Lugnica where the pledge is reviewed. The next ritual will be held three years and a month after the beginning of the royal election.


 * Emperor Selection Ceremony (皇帝選出の儀): A method which the Vollachia Empire uses to determine succession to the throne. The “process” begins with the current emperor conceiving children with women from all corners of the country. Those children are supposed to then vie for the throne, and the last known survivor becomes the new emperor. This ceremony is an example of the emperor himself following the country's ideals, earning it the support of the people. It officially begins when the current Emperor is burned to death by the Yang Sword or otherwise loses his credentials. The Emperor's children are gathered together to test whether they hold the credentials by seeing if they can wield the Yang Sword without burning to death hence signifying the time to fight for the throne has come. It's also possible to decline to take the sword and thus exclude yourself from succeeding the throne, however such people are typically killed during the ceremony or when a new emperor takes the throne. The ceremony typically lasts under a year.


 * Western Margrave Territory Meeting (西方辺境伯領会合): A meeting that takes place between people of notable influence regarding the rule of the Western Margrave Territory, the territory owned by Roswaal L Mathers.

Fauna within the Re:Zero world include...

Dragons (竜, Ryuu): In the days of the Witches, Dragons freely roamed the world in numbers. They lived in flocks everywhere around the world, and formed smaller communities or factions, which were led by their chosen Dragon representatives, who were renowned around the world. They acted very similarly to Spirits and Evil Spirits, however, unlike them, Dragons freely expanded their territory rather often During the era of the first Sword Saint Reid Astrea, however, most of them were slain by him, pushing their species to the brink of extinction. They were capable of speech and were rather intelligent beings. There are even instances of individual Dragons forming pacts and vows with humans, in order to create a world where both Dragon and men could coexist. According to the author, the models for Re:Zero's Dragons were taken from European dragons, though they do sport some pretty apparent differences. Just like the European dragons, they have large lizard-like bodies and sport a pair of wings, though there were instances of Dragons with two pairs of wings, such as Volcanica. Additionally, some Dragons hunted and killed people for various reasons, oftentimes to secure new territory. In turn, humans came up with a title, referring to them as Evil Dragons (邪龍 Jyaryuu). It was mentioned that the term Evil Dragon is purely a viewpoint of people who were wronged by these beasts, rather than being an actual race name.


 * Earth Dragon (地竜): Dragons created by Volcanica. Much like horses on earth, these wingless, land-based dragons are often domesticated to be used in menial labors such as transport or in warfare. They have varied body types and colours to suit different terrains, environmental conditions and jobs which makes them excellent to work with. All Earth Dragons are born with Wind Evasion a species-based Divine Protection. Specific species types known include Flanna (フランナ種), the most numerous versatile species, Eliq (エイリーク種), an earth Dragon species for cold environments, Agaress (アガレス種), an Earth Dragon species for desert environments, and Diana (ダイアナ種), the species of Patrasche, a prideful and relatively rare species.


 * Water Dragon (水竜): A lesser species of dragon, like Earth Dragons. Water Dragons are aquatic creatures, with long serpentine bodies, with short stubby limbs. They have blue, slippery skin and have a head that resembles a dragon's. Their mouths are crowded by sharp fangs, and catfish-like whiskers extend from its snout. They are harder to domesticate than Earth Dragons. All Water Dragons are born with a Divine Protection which protects them from the effects of the water.


 * Winged Dragon (翼竜): A lesser species of dragon, like Earth Dragons. They are nearly impossible to domesticate, though some people in the Vollachia Empire had found a means to do it. These dragons have been shown capable of surpassing the speed of sound. It is likely that they are also born with a similar Divine Protection as with Earth Dragons and Water Dragons.


 * Liger (ライガー) Ligers have an appearance that is similar to wolves on earth. Ligers are a somewhat rare type of species, as they are often seen in Kararagi, but not so much anywhere else, and especially not in Lugnica. Ligers are very territorial, so they can be difficult to raise. They are often used by the members of the Fang of Iron mercenary group for menial labors such as transport or warfare. Although they are similar to Earth Dragons, Ligers lack strength, but they are more agile and have higher speed and endurance. They have a high chance of winning if the two were ever needed to fight in a melee.


 * Falo (ファロー) Falos are animals with a quiet disposition with high stamina comparable to the likes of Earth Dragons or Ligers. They are valued in all countries, however, they have an element of cowardice in their nature. Long ago they were referred to by the name "Grim Oxen".


 * Demon Beast (魔獣): See Demon Beast.


 * Demi-Beast (亜獣): A kind of species that appeared after the flooding of Priestella. Interestingly enough, they are not related to Demon Beasts. The beasts are described to be a cross between steel and flesh, having weapons like axes, spears, and such protruding from their body. Most are blind and lack certain body parts. The beasts are Capella's creations, of which, she heavily implied that they were made from corpses. It's left unclear whether her Authority resurrects the corpses and transforms them, or if she does it moments before their death.


 * Corpse Soldier: A name for a type of undead that retains some measure of their marital ability after death. When destroyed, the magic will be released and the victims will momentary returned to the state they were right before their deaths but breakdown into ash right after.

 * Ryokucha (リョクチャ): A popular drink created in Kararagi.


 * Bokko Fruit: A small purple nut that can stimulate mana within a person's gate when taken. It's mainly used in emergencies when a Magic User's internal mana is depleted and their gate becomes dominant but needs to use magic. However, because this forcibly reactivates the gate it carries a serious risk of damaging the gate itself.


 * Fannel Fruit (ファネルの実): The Fannel Fruit is a small fruit that when taken as powder it can make a person's body feel hot, make them honest, and bring about strong drowsiness. Possibly alcoholic in nature.


 * Karnago Powder (カルナゴの粉末): Powder with a strong odor that can erase a person's body odor along with the powder's smell within minutes if applied to the body.

Other cultural aspects and items include...


 * Magritza's Guillotine (マグリッツァの断頭台): A book which Beatrice was reading during the second Arc. It's classic Vollachian literature which originates from a tale about a character named Magritza. There are noticeable scenes such as the "interaction between an old disciplinarian and the preceding King" and "The old king who deceived his disloyal attendants and allows assassins he hired himself to sweep him away." At the end of the story, the hero who conspired with the Father King is guillotined.


 * Dragon Insignia: A small ceremonial touchstone badge with an inset red jewel in the middle. During Royal Selection, it marks those who have the qualification and potential to become the Dragon Maiden and as well as Lugnica's next ruler, signified when its jewel shines brightly.

 * Dragon Tablet:Dragon Stone ep.12.png A large stone lithograph bequeathed by Volcanica to the late royal Lugnica family that could foretell the fate of the country. It acts as a guideline to shape Lugnica's future. For example, the idea that the Royal Selection would be held to choose a new ruler and the specifics came directly from it.


 * Warning Stone (警戒石): Warning Stones are capable of alerting people of intruders.


 * Night Banisher:Night Banisher.gif A special type of ammunition composed of a mass of condensed light lagmite. It can be fired from mana-crystal cannons into the sky to generate an artificial sun that lasts for an hour. A drawback is that it so bright it will blind anyone who has their eyes open during its initial activation.


 * Crystal Lamp (結晶灯): Crystal Lamps gather mana from the atmosphere during the day and can be lit at night by using the accumulated mana.


 * Anti-Mana Crystal (退魔水晶): A type of crystal that can neutralize or dampen the presence of mana by forcing the energy back into a colorless state where it becomes dominant and invisible. As long as it is in effect, any power related to mana such as magic is weakened. Several of these were used against the Hakugei's mist to thin it out.


 * Dragon's Fang (龍の牙): A tool used in summoning Valgren. According to Stride, if the fang sucks the blood of heaven sent children, a blood crazed dragon will appear. He summoned the dragon using the blood of twenty Lugnican citizens.


 * Candle: Used to determine the time in the Flower Town. At the time of trouble, Toto gave away 2 candles to the one he/she liked and started a fuss on the street.


 * Black Water (黒水): Poison that sank to the bottom of the lake at Elior Forest, from the Black Serpent that attacked 100 years ago. It has congealed and now acts like a living thing. It's a weapon that melts and absorbs anything the poison touches, showing traces of intelligence.


 * Brightbugs (光虫, Hikarimushi): Strange objects which have an unnatural flickering glimmer to them. They are relatively hard. They make use of magic, but they are quite brittle since they are not that dense. They seem to have appeared in Costuul after the production using Magicreation Tools started. There have been no confirmed sightings of them in other cities.


 * Rare Blood (稀血, Mareketsu): Blood that slightly differs from the usual kind people possess. Of its powers, it's said that it can even captivate dragons, and people who possess it are targeted. Rare Blood is not inherited.


 * Evil Sealing Stone: A crystal created with a specific and complex technique involving Yin magic, more specifically a version of Shamack, which separates a person from their consciousness and solidifies around them, effectively sealing them away. The most famous example of creating such a seal is the Evil Sealing Stone used to seal off the Witch of Envy four centuries ago, however, during the events of Arc 6, Julius Juukulius had used the exact same technique but on a much smaller scale in order to seal off the Sin Archbishop of Gluttony. It's also worth noting that the Sin Archbishop of Wrath had suffered the same fate after her capture at the end of Arc 5.

Equipment
Meteor (ミーティア Metia): A tool that allows people whose gate isn't working properly to use magic. It is known as a magic generator that does not require the user's mana or training and everyone is able to use Meteors.

 * Scarlet Little Finger (朱色の小指 Akeiro no Koyubi): A red ring which was used by Stride Vollachia, which was capable of casting a curse that rotted the target's limbs, eventually leading to death.

 * Echidna's Meteor Staff: A meteor that was created by Echidna and is currently used by Felt. It is able to charge up and fire a giant burning blast of light. It's undodgeable even by Reinhard because it locks onto a target's gate and tracks them down until they're hit. It Drains the user of almost all of their mana.
 * Void Garb (虚影装 Kyokagesou): A meteor that was loaned to Reisel by Capella. It allows the user to create shadowy humanoid figures using their hair that can be controlled.

White Fox's Nest (白狐の巣):A Meteor which captures a person and makes them do a trial based on the owner's magical experience and mana. The target cannot escape unless the trial is finished, and the target cannot die within the trial either. When Ezzo used it against Subaru and Rem, thinking they were Roswaal and Ram, the design of the inside of the meteor was a plain white room with white walls on all four sides and a crystal in the middle. When a person entered a room, the iron door behind them closed and did not open until the trial ended. Ezzo forced them to challenge four trials in order to get out of Meteor. At the end, they had to smash the crystal for the trial to end.

The Ten Swords of Power: Ten Swords of Power are ten swords which the author has stated to be ridiculously powerful, that exist in the world. They're stated to be sharper and more beautiful than normal swords, and have magical properties. They are separated into three categories; Enchanted Swords (魔剣 Maken), Holy Swords (聖剣 Seiken) and Bewitched Swords (妖刀 Youtou). The swords are listed by title below:

An Enchanted Sword supposedly crated by an unknown swordsmith out of the finest steel and blessed by the very Sword God itself. It was gifted to the First Sword Saint and has been handed down to those of the Astrea family who have received the Divine Protection of the Sword Saint successively for generations. It has the power to cut through almost anything and it cannot be destroyed, however, a special condition is needed to be met in order for it to be drawn. Its sheath is known as the Dragon Claw (龍爪 Ryuusou) since the grooves on it are said to have been caused by the Divine Dragon Volcanica's claws. The Dragon Sword is the strongest sword in the world, also held as the sharpest and most beautiful. Legend has it that the blade has drunk the blood of the thousands of dragons it has butchered. Countless legends surround the sword, like the legend that speaks of how Reid Astrea supposedly used the sword to slay countless dragons with a single blow, though no one knows how accurate the sayings are. Once the Dragon Sword has been drawn, defeat is no longer an option.

According to Julius, even when sheathed, Murasame emits extreme cruelty and bloodlust.


 * The Dream Sword (夢剣 Yumeken) also known as Masayume (正夢):Dream Sword Masayume.jpg Masayume is currently wielded by Cecilus Segmunt. The sword is classified as an Enchanted Sword.

 * The Yang Sword  (陽剣 Youken) also known as the Yang Sword Vollachia (陽剣ヴォラキア Youken Vorakia): A sword that appears out of thin air when the user wishes to use it and it cuts and burns whatever the user wishes . It is mentioned by Berstetz Fondalfon that only those who have the necessary qualities for the throne of Vollachia are able to wield the sword.

The current know wielders of the sword are Priscilla Barielle, Vincent Vollachia, Drizen Vollachia, Lamia Godwin and Stride Vollachia.
