Allegiance [9]
A dragon's Universe Baptism was different from what a human went through.
The concept was the same. The universe would ask them to prove their worthiness through a series of tests. If they succeeded, then they'd be allowed to proceed to the next level.
Dragons didn't have a class system. They trained like beasts, which was why their system relied more on bloodlines and the like. They passed the 4th class barrier to be granted a purified bloodline. Later, they would challenge the world to become Godbeasts.
Only Holy Dragons could be considered True Godbeasts, but they weren't the only dragons to reach this level.
Theoretically speaking, any dragon could become a Godbeast.
The 4th class barrier was exactly their opportunity. If they managed to cross it, all of them could gain bloodlines akin to nobles and the potential to improve them even further.
