SkekSil is a major supporting antagonist in the Kingdom Hearts Unlimited Saga, first appearing in "The Keyblade Wars" as a high-ranking member of the Skeksis Cult tangentently allied to the Order of the Old Ones, though their connections date much farther back to the time of the Age of Peace.
Formerly known as the UrSkek Chanter/Court Composer SilSol, who once briefly traveled forward in time alongside several other members of his kind to save the life of the dying Michael Mouse; he fell to darkness because of his lust for social status & power. Because of this, he degenerated into the Skeksis Musician SkekSil and fell from Heaven with the rest of his kind. He then began manipulating events around him in order to get himself elected Chief Secretary of State, and thus next in line to the Skeksis' throne after Emperor skekSo, with whom he formed a powerful political faction consisting also of skekEkt the Ornamentalist and skekAyuk the Gourmand. Despite his position, he was despised by the other Skeksis for his wheedling voice and underhanded nature.
