Frozen Egg
Name: unnamed
Species: Sora Kamitori
Birthday: Thursday, July 19, 2018
Owner: SilverWolf
Element: Neutral 
This isn't an egg, but a piece of lightweight folded paper.
Kamitori are not truly alive, but are rather the physical manifestations of magical charms. Specialist magi cast living spells on inanimate objects, bringing them to life for short periods of time. Each spell has a time duration, and the more powerful the spellcaster, the longer the creature remains animated. Kamitori are one of the oldest forms of charm creatures, and usually the first project a new artificer creates when they join the Artificers Association. A small square of folding paper is charmed and takes the shape of an egg. Given enough attention, it will refold itself into the shape of an animal, usually a bird, and behave much like a bird until its spell wears off. Although the spell usually fades after a few days, a little tweaking can allow the kamitori to feed off the energy of the things around it -- heat, light, noise, and even affection -- and extend its lifespan indefinitely.
