Shape-shifting usually applies to animal-humanoid transformation, and comes in three flavors:
- Made shape-shifters. These are beings who are cursed or spelled with the ability to transform into something else.
- Born shape-shifters. These are broken into two categories:
- Removable skin. Selkies and Sinaa fall into this category.
- Non-removable skin. Wulvers and Zimwi fall into this category.
There are various shape-shifting group among most of the Seven Peoples, and their cultures tend to be built around their abilities and maintaining genetic purity so as not to lose their ability. For the record, that can happen. Shape-shifting Kin rarely retain the ability to transform past the second or third generation.
