Knock was the deity in the Billykins world of the same name. Knock, Llabyrinth, and Compass Mountain were various faces of the cube that was Knock's Dominion.

Knock was a Chaotic Good marble dragon deity for clerics. In Knock's world, worship was determined by the professionone followed as much as the morality and ethos of the worshipper. He could see six seconds into the future.

Once upon a time the mortal human named Roger Bacon was incarnated as an avatar of Knock. Guipago and other Billykins deities also incarnated as Knock's Iahklu peers. Bactor became the Black Rabbit Gorm. The er-perhenne Chaotic Evil deity Al-bac was of course defeated by Iahklu ingenuity, and broken into 1001 pieces. Somewhere we lost the patella, but that was eventually recovered.

Roger Bacon was eventually assimilated into Yama Dharma to fight yet another Billykins incarnation of Al-bac. Knock's divine nature was Inspired by Clio to remain within Worlorn to fight as Tiresias against Al-bac's Worlorn incarnation, the Demonlord Tloluvin of Red Light.
