Fionn travels to the capital of Tara, which is set aflame each Samhain by Aillén the Burner, one of the Tuatha Dé Danann. Goll and the Fianna are powerless to stop it, since Aillén puts everyone to sleep with a magical tune. Fionn inhales poison from his own spear to prevent sleep, and dispatches Aillén. He reveals his identity to the court, and the king grants Fionn his rightful position as leader of the Fianna. Goll steps down, and engages in a truce with his enemy.
