In act 3, the Cravann army has lost in battle, and Fervaal remains alive, in spite of seeking death in the conflict. He then asks Arfagard to kill him as a sacrifice to fulfill his duty. However, Guilhen appears, which reawaken's Fervaal's love and causes him to change his mind. Arfagard tries to kill Fervaal, but Fervaal instead cuts down Arfagard. Fervaal takes Guilhen away from the battlefield and they begin to ascend a mountain. Exhausted, Guilhen dies in Fervaal's arms. Fervaal laments the deaths of both Guilhen and Arfagard. He then hears the wordless chorus singing the "Pange, lingua" melody. Fervaal carries the body of Guilhen up the mountain, as he realizes that the reign of the "new God" is forthcoming. As he disappears from the scene, an "ideal sun" begins to shine.
