About the Story

In the medieval kingdom of Highgard, the greatest threat is neither beasts nor ancient curses, but the crown itself. A king consumed by contempt for his realm dares to defy fate, challenge the gods, and sacrifice everything he holds dear.

His goal is not salvation, but erasure — to dismantle Highgard and seize the neighboring throne of Valtoria. As magic spreads like a slow poison and political intrigue tightens its grip, three lives become bound to the coming collapse:

Yinyue — an impulsive young mage whose fierce compassion often outweighs caution, willing to burn herself to protect others. William — a restless soul avoiding responsibility, torn between desire and duty, drifting until choice becomes unavoidable. Charles — a loyal knight divided between honor and truth, quietly searching for devotion in a world hostile to honesty.

Love, loyalty, betrayal, and forbidden bonds intertwine. When destruction looms, one question remains: can Highgard's fall truly be stopped — or only survived?
