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.

'The Ripper' was found as an egg by Dark Card himself, and brought home to the Styxin stronghold. She hatched and was raised by Dark Card before being frozen in her current state. She now acts as a guardian to the stronghold, a faithful underling to Dark Card himself. She is grateful for him saving her, and because of this, is proud to be a Styxin.
