AdventureQuest Worlds

The player enters the game arriving at Oaklore Keep while it is under siege by an undead army led by Sepulchure, the leader of the world's forces of Evil. Sepulchure advances towards the capital of Swordhaven, the seat of King Alteon the Good. Drakath, the Champion of Chaos, interrupts and attacks them both, corrupting them. Sepulchure taunts that he cannot be killed, so Drakath extracts his core and smashes it, destroying him; his daughter screams from his flying fortress. Drakath shoots down the flying fortress, proclaims the era of Good and Evil to be over, and ushers in the Age of Chaos.
