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.

In stark contrast to her name, Keys is exceptionally good at finding things that other dragons have lost. Most of the time, she hasn't even set out to find the object in question. Somehow, she just seems to stumble over it in her wanderings about the caves. The other dragons are grateful for her successes and really wish they could help her find the key to her own cave that she lost one day a very long time ago.
