Corus is a fractured world, where nations vie for dominance amidst the lingering shadows of a catastrophic magical past. As ancient powers resurface and new threats emerge, ordinary individuals are thrust into extraordinary conflicts, forced to confront the dark forces that seek to reshape their future.

It's a dark exploration of power, consequence, and the enduring struggle against encroaching darkness.
