Attila
After Attila destroys Aquileia, Odabella asks for a sword so she can avenge her father, whom Attila killed. Roman general Ezio proposes dividing the empire, while Foresto and survivors arrive in the lagoon and plan a new city. Odabella and Foresto reunite. Attila dreams that Pope Leo warns him not to march on Rome. Foresto later plots to poison Attila, but Odabella intervenes. When the Romans ambush the Huns, Odabella stabs Attila with the sword he gave her, and the conspirators declare their people avenged.
