The protagonist, Darius, was once a trusted knight in a kingdom that fell into corruption and ruin. Betrayed by those he once served, including his closest friend, he was left for dead after his kingdom was razed. He returns with a burning desire for revenge, wielding forbidden powers gained during his exile. Along the way, Darius encounters unlikely allies, enemies, and discovers the darker side of his vengeance-fueled journey.
