In the first act, Andronicus, head of the "Coalition of the West," fights the monsters of Bludtharst Heterodyne to a standstill and is "hailed as 'the Storm King' in the unforgettable Hammerhead Chorus!" "After the famous comic interlude" with a shoe-stealing maid named Capezia and the coalition recieving "the blessings of the five good emperors," Andronicus witnesses Euphrosynia Heterodyne being menaced by the "mad sorceror-prince, Ogglespoon," and falls in love with her. The act closes with the spirit of Europa prophesying that only when The Storm King and Heterodyne princess are wed will there be peace.
