I got bored. And I've had an audiobook to finish... So this happened.

Zenith is an OC of mine, a shapeshifter tormented with some sort of disease causing dark discoloration of skin and its appendages (scales, hair, feathers, etc), mostly around the spine. He can change forms and colours freely, but those dark patches are present independently of what he shifts into. On black animals it looks a bit similar to spots on black panthers, hard to see but still there.
The dragon form is his "original" one. Besides, he likes various cats, sometimes birds of prey, but he also enjoys shifting into random species just for fun. As a human, he usually has longer hair.
