In the deepest darkest part of Ren's soul sat the most powerful mortal being to have ever walked the multiverse. He has been called with many names, he was called the original, the prime warrior, the chaos bringer, the truth seeker, the defiant one, the true hero, and many more. All of these nicknames were what he has been called by over the years as his actual name was lost in the flow of time.
It has been countless eons since he started his crusade, his final struggle against the being that toys with the fates of everything. He was the one who has been fighting for eternity was finally seeing the end of his road.
All of his reincarnations have been the strongest of that era. Unfortunately not one of them had the same level of power as he, but still, they were able to continue the fight. One of them was even able to kill a part of the ORIGIN.
