Arad himself couldn't believe what he was hearing; the heart had enough power in it to make him an adult dragon. At long last, he can now see what a void dragon is supposed to be like.
Granted, after becoming an adult, he still has to grow to a mature adult, then an old dragon, an ancinet, a wyrm, then a greatwyrm, face the twilight and survive to reach past it and achieve the peak of his kind.
Arad could feel it; his bones, flesh, and even mind had started transforming into something else. Adult void dragons aren't supposed to remain in the mortal world, but the system, not this pale angel, is the one allowing them to stay.
Of course, Arad didn't forget to ask the important questions, but the answers he got only opened the door for more questions. He asked about the Dracorage Mythic, the meteor that is supposed to drive all dragons mad.
