This hatchling appears to be... dead?

Perhaps not. It seems to be active during the night.

Young dragons are relatively defenseless. They are born with relatively soft scales, which are shed and replaced with harder ones as the hatchling matures. Once a hatchling’s wings grow in, it typically marks the beginning of maturation. At this point they are often capable of hunting on their own and are usually left alone by their mother.

This Vampire is a disappointment to his parents. They were aiming for him to grow up to become a beautiful Falconiform Wyvern, but some old Vampire got to him before he hatched, and now he lives as one of the undead. His proud parents cast a spell on him to prevent him from biting any other eggs. He lives with other Vampires, though unable to spread his species.
