Beacon from Beyond (Book 1 Complete)

Leven lived his entire life being the best person he could possibly be, careful to never let his anger issues define him or hurt anyone. He was known for his kindness despite his disorder, and was proud of it, until he finds out that it might've all been for nothing when the people he cares about the most don't feel the same to him. Betrayed, he attempts to lash out at someone for the first and only time in his life, only for it to result in an unsatisfying death he refuses to accept. His soul's struggle against the end eventually garners attention from outside powers, and he is rescued by something calling itself the System. In return for a second life, it tells him he must ascend to Godhood and beyond before the damaged System loses energy and dies, destroying a section of the multiverse with it. Now reincarnated into a brutal new primitive world, the quest is quickly forgotten as he struggles to survive, much less ascend. Despite that, a fire within him continues to push him to a future he can hardly see.
