In the throes of apocalyptic devastation, the Defiled—grotesque abominations born from the Great Collision—hunt relentlessly across ravaged lands. Humanity's sole refuge lies behind the formidable barriers of the Sanctuary of Everlast, where survival has become the measure of existence. When Alden ventures beyond the Sanctuary's protective walls, a chance separation from Celeste—his childhood companion and unconfessed love—sets his destiny in motion. Thrust into a desperate struggle for survival, he awakens as a mage, but not through conventional means. Instead of wielding orthodox power, Alden discovers an extraordinary ability: the gift of decay, a force that corrupts and unmakes all it touches. During his mystical ascension, a haunting vision arrives—his future self warns him of a terrible truth: the Asterons, the celestial saviors of humanity, cannot be trusted. Yet this revelation carries impossible weight. Celeste shares a binding pact with an Asteron—one of the Divine Sovereigns themselves. Caught between the love he cannot confess and a warning he cannot ignore, Alden must navigate a world where salvation itself may be humanity's greatest deception.
