A young monster slayer, Thoma Fayren, begins taking his first steps into a world he knows little about after many years in an isolated community. Fate, however, has other plans in mind as he quickly discovers that not everything is as he thought it would be, forcing him to grow in ways he never knew were even possible.

Through the help of his mentors, he learns how to better manipulate mana, but begins to question the true nature of everything and everyone around him, and what he discovers is worse than he could ever imagine... far worse.
