A changechild is a creature who undergoes extreme magical modifications to its body. A changechild can begin as a human or some other creature, though human-based changechildren frequently conduct the modifications themselves. The type of magic involved is similar to that used by the Tayledras and their Kaled'a'in fore-bearers to create the Shin'a'in battlesteeds and the Tayledras bondbirds. However, the technique is taken to an extreme that the Shin'a'in and Tayledras consider to be obscene.
