Ascension par Régression Ancestrale

A century ago, an earthquake ruined the world. Yet, it also gave all beings on earth a new chance called Reversion. By Reversion, all creatures could get their ancestors' power through DNA. The more one reverses, the stronger one would be. While others reversed as simple warriors, Soren Lane was special. He could choose to reverse to be anybody. Then he chose the last and most famous paladin, Roland. And, he's aiming to reverse a few more times and to be the only immortal in the world.
