Canetol Come Again is an idea in the Faith o' Nine that states that one day, Canetol, one of the Nine Gods, will come down to this Earth as a human being to be the King Clad in Black, and bring about the Fall of Humankind. He will be a reincarnation of Billow the Slave, and thus this idea ties into the nameless child of the Faith of the Nameless Child of the Blood Children.
