Kosdresheru Shadowshifter

Kosdresheru Shadowshifters, also known as just Shadowshifters, are slimey shapeshifter creatures similar to familiars. They are native to Ebrya and form from a strange black plant. Usually, these things will have deformities, like a missing eye or no mouth (although most can't speak either way). Their only way to shapeshift into another creature is to harvest their skull, which makes them widely considered terrifying and bloodthirsty. Their first kill is usually what they present as (e.g Bastet presenting as a kitten and Pig presenting as a borzoi)

Additionally, all shadowshifters have the same eye color, and the older they get the more 'solid', or less blob-like, of a form they will have.

Ages of Shadowshifters vary wildly depending on multiple factors like if they're living in the wild or not, but wild Shadowshifters typically live 4-20 years while those in captivity or with ways to protect their 'skin' from getting damaged can live up to 350 years.
