I didn't climb, I was thrown and I kept falling...until the Abyss stared back."When the world ended, the tower rose from the earth, and humanity was forced into a game of survival against nightmare-fueled monsters. Machines stopped working and amidst the chaos, Xior Arden, a broken orphan boy with empty eyes was cast into the lowest depths of the Abyss.There, the weak don't die quickly. They suffered and so he did suffer.But the Abyss chose him.With the power to absorb runes from fallen monsters, evolve his body into higher forms, and steal the essence of the creatures he kills. Xior begins to climb the tower, not as a hero. But as the thing which the Abyss itself fears:A Monarch born in the dark.***Additional Tags: TowerClimbing, Anti-hero, System, Revenge, WeakToStrong, MorallyGreyProtagonist, CunningProtagonist, ArrogantProtagonist***
