For twenty years, Paladin Arthur defended the Last Stand Wall, keeping the undead at bay. Yet Queen Isabella condemned him for refusing to dismantle its ward to access a mineral vein, dismissing the undead threat as a lie. Branded a traitor by the court and a villain by the people, Arthur stood by his promise to the late king. When ministers secretly destroyed the ward, he left in despair—only to be blessed with divine power and crowned a Holy Spirit. Soon, the undead breached the Wall, plunging the empire into chaos. With the queen begging for his help, Arthur must decide whether to save the very kingdom that betrayed him.
