Jocelyn, guardian of the last light temple, catches her fiancé Kieran cheating with Aspen. They frame her and throw her in prison. To inherit the temple, she marries Lokian, a criminal who is actually the light god, betrayed by his best friend Warwick and sealed away. She repairs the Dawn Sword with their bond, he reveals his power at the light festival. Together they gather sacred relics, break his chains with her blood, and restore his divinity. He defeats Warwick, deposes Kieran, and rebuilds the temple. They swear a blood oath and have a son. But at the celebration, a blood-red aurora falls, an ancient darkness wakes, and a greater storm approaches both realms.
