Secretly trained as the legendary "Wolf God," he saves Lion Clan princess Lia from dragons — earning her worship, though she scorns his real identity. At the Beast Festival, he crushes rivals and reveals his power. Framed by stepmother Celine and prophet Gultan, Thorne exposes their conspiracy at the Ancestral Grounds, unveils his Wolf God identity, and proves Celine poisoned his mother. He kills the transformed Gultan, avenging her. Celine and Byron are imprisoned. Lia confesses her love. Thorne is named Crown Prince. But as the city celebrates, a dragon roar echoes — a greater crisis looms.
