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.

Eternal beauty... is it worth it... What things are given up in return for immortality...

Beauty, never given a chance to live, never given a chance to even grow up before dying. Without knowing what she has never tasted, she accepts the life she has and the taste of blood as the only things that matter, the only things that can give her joy.
