Lyvia's dragon form

Lyvia is a dragon that was raised at a monastery as a mount for the local city's lord, however, she got loose and is now 5tons of asocial hatred who's favorite food is... anything sapient and close enough to catch. Unlike other dragons, her specific breeding allows her to entrap the souls of those she's consumed; they are hoarded and used to power foul magic.

A lot of her pride hinges on fitting into this false-idea of what a dragon is supposed to be, stuffed into her head due to growing up among monks. She prefers it when she can sort people into simple category boxes that fit her world view.

She can transform into other species that she's eaten before, but the collar affixed to her neck follows her new form, scaling accordingly.
