Pirates in Oz

Peter returns for a third time, washing up on the Octagon Isle after a shipwreck. He joins King Ato, who has been abandoned by his subjects, and Captain Samuel Salt, who has been abandoned by his crew of pirates. Together, they sail on the Nonestic Ocean (which surrounds the landmass of Oz and its neighbor countries). Meanwhile, Ruggedo, the deposed Gnome King, is back. He had been cursed with loss of speech by a magical "Silence Stone" at the end of his previous appearance in The Gnome King of Oz, and is scraping out a living as a peddler and beggar. He decides to answer an advertisement for the position of King of the Land of Menankypoo, whose people are also mute. These people demand "a dumb king" and Ruggedo meets this requirement. While serving as king, he recovers his ability to speak, joins forces with an ambitious magician, and also becomes leader of Captain Salt's mutinous pirates and Ato's rebellious subjects. He trains these followers into a military force, and attempts once again to conquer Oz.
