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.

She is the pet of the Vampire Clan of Lenapet's clan, since she was caught by Frostrune, the ice dragon, and frozen young. She is calm, and nice. She always follows Vynsa Bloodwing around for protection, and is usually trying to calm down the wild leader, Bloodrune.

Her role is small, just to be there to comfort down dragons. She is supposed to serve all the vampires, but she really just does chores for Vynsa.
