King Pluto is one of the three original rulers of the kingdoms of the keepers. He is not a creator of the kingdoms. He is the ruler of Aorth, the underground kingdom. In "The Dragon's Eye" Erec's adoptive mother, June, was being held in Pluto's dungeons. It is unclear at first why one of the rulers would have his mother in his dungeons. His dungeons contained Shadow demons and destroyers. King Pluto has been corrupted by Baskania, playing many roles in his plots to rule the kingdoms of the keepers.
