Humanity stands at the brink of extinction. Earth has been bombarded by forces beyond our understanding. In the aftermath, monsters roam the Earth while humanity is forced into a few small safe zones, but not all is lost. When the shadows fell, so too did hope.

I’ve always wanted to conquer the Big 5 dungeons ever since one of them took the life of my father nearly fifteen years ago. Nobody ever said the Path of Progression was easy, but my burning desire to dive can’t be quenched. I just never thought I’d be prohibited from getting a diving license just because I tried to help a bratty blonde girl get hers.

Arden was left in the village by a dying mage, who never returned. With no way out of the village on his own, he had always held onto the hope that one day his magic would awaken and give him access to his spheres. But he’s about to turn eighteen and it’s never come. Instead, he’s settled into his lot as a sarcastic and quick-witted innkeeper. That all changes one night when his old flame, who escaped the village to become a mage’s anchor, returns. Ard’s life is about to go through some dramatic changes, and he’s not ready for them.
