Fools went in search of it, and the clever never ventured into it. Only when its baleful mysteries spilled unto the earth did all hear its name — the Abyss.A single drop of its blood could give someone the power to control shadows, move faster than sound, or strength greater than the strongest man. Yet, it all came at a cost; the blood would always make sure those who consumed it became part of the Abyss, with one exception — Alice.

Gifted a second chance at life, a chance to turn her life around and claim vengeance against her family, a chance to dive deep into the Abyss and gain the power to govern her own fate, Alice took his hand, unaware of the destiny unfolding before her.
