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.

Incendia is somewhat of a daredevil.  He scares the other dragons living near him by attempting to do things such as climb cliffs without using his wings.  He is constantly declaring rivalries with other dragons to try and prove he is just as good as any other dragon- even if he is frozen.
