The Celestial War shattered the Heavens; after millennia, the battle still rages. On the most important day of Zahra's career at the Gallery of Time Museum, everything unravels. A mysterious package arrives from her estranged father, and the Atar'zul, a coveted relic that could secure her promotion, goes missing. While betrayal festers within the museum, a long-lost love returns, throwing Zahra's world into chaos. Kyden, a warrior angel and demon slayer, has guarded the spiritual realm for centuries. When a famous archaeologist and a forbidden relic rumored to hold the power to tip the balance between Heaven and Hell vanishes, Kyden is forced to protect a human, a duty he vowed long ago to never do again. Together, Zahra and Kyden must face rising demon threats and the cursed magic of the Atar'zul. As darkness closes in, they join forces to defend their realms and find that ending the battle means trusting each other. Sacrifices must be made-the cost of which might be their very souls. Welcome to the battle for humanity's future-a story of loyalty, temptation, and the fragile line between light and shadow.
