Arkhan's World is a planet in the Milky Way galaxy where the Tok'ra left Harry Maybourne after they transported him away from Earth. He became King Arkhan I and ruled the planet after he was believed to be a prophet. The Goa'uld Ares claimed this planet as his own, but with help from an Ancient Time Jumper, Ares was killed along with all of his Jaffa. (SG1: "It's Good to Be King")
