After they have left Wolf appears with some warriors. Their time of revenge is near; Wolf delivers the King's shoulder belt to one of the soldiers and orders him to rouse the country with the cry "Thule is in danger", and to summon all the King's loyal subjects against Hiram and Teut the apostate.
Night sets in and the priests of Moloch march forth from the temple, warning everybody away from its door.—
Teut keeping guard sits before it in deep thought. Suddenly he hears a well known voice. A roe appears and springs into the grove of the temple followed by Theoda, who with her spear leaps lightly over the wall.
For a moment Teut stands spell bound, but remembering the awful warning he darts after her.
When Theoda emerges from the grove alone, she suddenly recognizes the fatal place. Seeing Teut she implores him to save her from death. In his first mad impulse he is about to stab both himself and her, but his love restrains him and in their mutual embrace they forget death and fear. When they awake from their trance and find themselves still alive and unharmed, Teut in a flash realizes Hiram's falseness and the hollowness of his religion.
He awakens Hiram, the ever sleepless, who, distraught at the prospect of losing all he has schemed and worked for hurls himself from the cliffs into the sea.
In the mean time Wolf and his companions have set fire to the ships.
The priests come out in the dawning morning and are horror struck to hear, that Hiram is dead. The priests' chant to Moloch is drowned by the wild cry of the people.
All now turn against Teut, and Wolf, unaware of his sudden conversion, stabs him in the side.
