You have only had your little paper egg for a few short hours, but already it has started to come undone. By now, it has completely unfurled and resembles a flat square of folding paper. There are no apparent creases, and the paper is made up of long, delicate fibers. Whenever the wind blows, the corners of the paper twitch almost like the paper itself is alive. You were expecting something to be inside, but the egg seems to have been empty.
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.
