Meteor

Meteors (ミーティア, Mītia) are ancient tools that enable the usage of magic without utilizing a gate.

Information
Meteors allow people to use magic without opening up a gate. However, instead of being used as tools, they are typically exchanged as gifts. Various types of meteors with diverse functions exist, but they are generally scarce in nature. Individual meteors differ greatly from each other, and it is rare for any two of them to have the same function. They have existed for at least 400 years. In the past and the present, the main issue underlying meteors is that they have tended to deviate from their developers’ intentions, creating trouble in the long run. Additionally, they were named after shooting stars, and they have been believed to have the capabilities to make people's wishes come true.

According to Stride Vollachia, meteors are also known as Curse Tools (呪具, Noroigu). Although they effectively function the same way that meteors do, curse tools have been observed to only allow a user to produce curses instead of normal magic.

Moguro Hagane
Moguro Hagane (モグロ・ハガネ, Moguro Hagane) is the Eighth of the Nine Divine Generals in the Sacred Vollachia Empire and a living meteor who governs the Imperial Capital of Lupugana's Crystal Palace. As a meteor, they are influenced by the one who sits upon the Crystal Palace’s throne. They have colossal toughness, a whirlwind fighting style, and an ability to alter the shape of their body. As long as Moguro’s true body, the Crystal Palace itself, remains intact, they cannot be completely defeated.

Conversation Mirror
Conversation Mirrors (対話鏡, Taiwa-kyō) are rare meteors that allow the user to communicate with others over a long distance by connecting with a separate Conversation Mirror, similar to a cell phone. Though meteors are usually scarce, Conversation Mirrors are relatively common and easy to obtain. A known method to reproduce Conversation Mirrors was invented, but the costs involved in doing so make the idea of mass producing them impractical.

Collar of Submission
Collars of Submission (服従の首輪, Fukujū no Kubiwa), alternatively known as slave collars (奴隷の首輪, dorei no kubiwa), are meteors that connects with the gate of the person controlling the collar and the meteor itself. The meteor administers electric shocks and causes scalding when used. It carries a small jewel in it, and without the jewel, the meteor becomes useless. When Reinhard wore a Collar of Submission during his diplomatic trip to the Vollachia Empire, it made him feel lethargic and limited his powers by a minor extent.

White Fox's Nest
The White Fox's Nest (白狐の巣, Byakko no Su) is a meteor that 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 the meteor. In order for the trials to end, the crystal had to be destroyed.

Void Garb
The Void Garb (虚影装, Kyokagesou) was a meteor that Mother loaned to Reisel. It allows the user to create shadowy humanoid figures using their hair that can be controlled. The user shares in the shadows' senses, including in their sense of sight and pain. The Void Garb was destroyed by Reisel to prevent the recoil of his shadows from killing him.

Beast Protection Bracelet
The Beast Protection Bracelet (獣護輪, Juugorin) is a bracelet shaped meteor that transforms the user into a beast when they sense danger. As a beast, the user gains a rapid influx of mana, making them stronger in combat. However, the user loses capabilities for reason whilst they are transformed, and it can be unconsciously activated in something like a nightmare. In the days of yore, the meteor was created as a resource to help humans out of pity. The Beast Protection Bracelet is currently owned by Colette.

Scarlet Little Finger
The Scarlet Little Finger (朱色の小指, Akeiro no Koyubi) was a curse tool that was capable of casting a curse that rotted the target's limbs. It had an uncanny scarlet glow. Stride Vollachia temporarily used the ring to hold Veltol Astrea's life hostage. After Kurgan was defeated in the Silver Flower Dance of Picoutatte, Stride ceded the ring to Wilhelm van Astrea as a token of his victory, and it was sliced into two, thereby stopping the curse from continuing to damage Veltol at the cost of his right arm's mobility.

Orb-shaped Curse Tool
An unnamed black orb-shaped curse tool created by Groovy Gumlet. It takes the lives of people engraved with a curse mark if they exceed a fixed distance from the orb. The curse tool was used to thwart gladiators from escaping the Gladiator Island Ginunhive in Vollachia.

Trivia

 * Magicreation Tools, invented by Roswaal K Mathers, are known as modern-day meteors.
 * Roswaal J Mathers speculated that a dagger once owned by Leip Barielle was a meteor.
 * Meteors have appeared in two Re:Zero IF chapters. One of them, in Re: Drowning Life in Another World from Zero, was Subaru's throne in Pandemonium, which could protect the area surrounding it from attacks as powerful as a sword slash from Reinhard van Astrea. The other, in Re: Natsuki Rem in Another World from Zero, was a photo-taking meteor in Kararagi.
