The world is ending. In one year, the god Vorath-Astra will descend and erase everything. The only hope for survival lies in the Celestial Oaths—trials set by the gods, granting the victors passage to the next world.

Fiora Di Lorenzo, a fallen noble, refuses to waste her last year in despair. Instead, she seeks to see the world before it vanishes. River Crowe, a jaded mercenary, cares little for salvation—only for the vengeance that drives him forward. When fate binds them together, their journey spans the vast lands of Castovia, uncovering the truth behind Fiora’s lineage and the betrayal that destroyed River’s life.

Through peril, wonder, and fleeting beauty, their paths intertwine. But as the trials loom and time runs out, one question remains—will they carve their own fate, or succumb to the end that awaits?
