And look! It has grown wings! It must be close to maturing.
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 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.
Bllax, when born, was very small. Not many of the dragons in the Hideout thought she would grow due to her tiny size, and some even thought to kill her since she wouldn't be useful anymore, but Blackberry would not allow it - she was ready to defend Bllax, since she was her child and not theirs. So, the dragons decided to leave it up to Flaming, their leader, to decide Bllax's fate. As soon as Bllax matured and grew slightly bigger, the leader's son brought Bllax to Flaming Burden. After seeing the condition in which the poor hatchling was, one of the Protectors healers, Snowed Sticks, was asked to come and see why the Black hatchling was so small. It turned out to be some kind of a sickness that had hit Bllax while she was still an egg. To prevent the 'sickness' from spreading, Snowstorm's Path was tasked with freezing Bllax so no other hatchlings hatch so small.
Despite her stunted growth, Bllax helps around with anything she can, so she isn't bored all the time.
