Edmea
In seventeenth-century Bohemia, Oberto and Edmea love each other, but Oberto’s father orders her to marry Ulmo. Edmea throws herself into the Elbe, and Ulmo follows; both survive. Edmea loses her reason and believes she is a river fairy until she recognizes Oberto at a celebration and recovers. She reveals she married Ulmo; he resolves to kill himself so the lovers can unite. Ulmo dies after Edmea grants his last wish, and Oberto’s father arrives with news that the marriage has been dissolved.
