Since the Second Impact, Khan endures relentless nightmares of the Nak spaceship's catastrophic descent—a haunting echo of humanity's victory over the alien invaders five centuries past. The tragedy stripped away everything: his mother's life claimed by the disaster, his body poisoned by Nak mana, and his family's home and legacy sacrificed to save him. Driven by visions he cannot escape, Khan enlists in the Global Army to master mana and reclaim his shattered existence. His quest transcends personal survival—it becomes an interstellar hunt to confront the Nak across the cosmos and finally silence the torment that consumes his every night. Through action-packed battles and dangerous adventures, Khan searches for redemption, romance, and the truth hidden within the chaos that shaped his destiny.
