In this world, even normal people can reach the realm of Gods. Of course, not everyone has the same potential as a dragon, but it is just a matter of time when you live long enough. The God of Thunder is the oldest dragon. Some may say he is the father of all dragons since he has many children, and there are no legends of his father.
As Hulum Ying, this dragon has lived long enough to be as powerful as a God would be, the reason why people never defeated yellow dragons. That's because there was only one yellow dragon so far, the God of Thunder was unique until the birth of Aetonth.
The bloodline of dragons is the same as with the mages, the closer the dragon is to the God of Thunder, the more powerful it can become. Yet, having children is not something usual, different from the other hundreds of dragons out in the world, the God of Thunder has children once every four hundred years.
