Xoth (or Zoth) is the green binary star where Cthulhu and his ilk once lived before coming to earth. According to the Xothic legend cycle, it is where Cthulhu mated with Idh-yaa to beget Ghatanothoa, Ythogtha, and Zoth-Ommog. Xoth is also the native home of Ycnágnnisssz and Zstylzhemghi, and was the temporary home of the latter's "husband", Ghisguth, and their progeny, the infant Tsathoggua. Tsathoggua later went to live on Yuggoth. Afterward, he fled to Cykranosh to escape Cxaxukluth's cannibalistic eating habits.
