Dragon

Dragons (龍 Ryū) are large and powerful creatures made up of an enormous amount of mana. However, Volcanica, the Divine Dragon, is the creator of lesser dragons (竜 Ryū), which are less powerful creatures that roam the world despite not being made up of mana like their creator.

Information
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-generation 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 is mentioned by Beatrice that this term is nothing more than a viewpoint of humans wronged by dragons, rather than a designated species name. According to the legends, Evil Dragons were all but exterminated by Sword Saint Reid Astrea, four centuries ago.

Types of Dragons
Dragon (龍 Ryū): The original type of dragons. They contain great power and are made up of enormous masses of mana.

Earth Dragon: (地竜 Chiryū): Dragons created by Volcanica. Much like horses on earth, these wingless, land-based dragons are often domesticated to be used in menial labor such as transport or in warfare. They have varied body types and colors 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 the Flanna species (フランナ種), the most numerous versatile species, the Eliq species (エイリーク種), an earth dragon species living in cold environments, the Agaress species (アガレス種), an earth dragon species living in desert environments, and the Diana species (ダイアナ種), the species of Patrasche, a prideful and relatively rare species. The Diana earth dragon species are the original earth dragon species from which all other earth dragons descend from.

Flying Dragon: (飛竜 Hiryū): A lesser species of dragon, like earth dragons. They are nearly impossible to domesticate, though some people in the Vollachia Empire have found a means to do it. These dragons have been shown capable of surpassing the speed of sound. It is unknown if they are born with a Divine Protection.

Water Dragon: (水竜 Suiryū): 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, as one must be trained from the very day they hatch from their eggs in order to recognise someone as their master. All Water Dragons are born with a Divine Protection which protects them from the effects of the water.

Trivia

 * In Japanese, the difference between the original Dragons (龍) and the lesser dragons (竜) is conveyed through the usage of two separate Kanji which both mean "dragon".
 * In the Web Novel, the Agaress species was previously known as the Gyrus species (ガイラス種).
 * Although not Dragons themselves, there was a rare demi-human race known as the dragonkin, which possessed the ability to make emotional connections with the three kinds of lesser dragons until they mostly went extinct. After driving ten other races to extinction, they were nearly led to extinction as a result of their extreme pride. The race's only known survivor is Madelyn Eschart.
