Imagine a world consumed by a brutal war, humanity teetering on the brink of annihilation against the monstrous Dalki. Just when hope seems lost, a hidden faction emerges: humans with extraordinary abilities, long concealed in the shadows. Some offer their gifts to aid the war effort, while others remain shrouded in secrecy, their motives unclear. Amidst this chaos, we find Quinn, a young man who has lost everything. His home, his family, all swallowed by the relentless conflict. His only inheritance is a mysterious, ancient book, stubbornly refusing to open its secrets. But fate, it seems, has other plans.

The price of power becomes terrifyingly clear, forcing Quinn to confront a moral abyss as his very life hangs in the balance. Will he succumb to the system's insatiable thirst, or can he find a way to defy his dark destiny?
