Keith was one of Xaq's friends, along with his brother Kurt. The two were fond of building mountains in their video game, Far Cry, and when an inexplicable mountain appeared in Xaq's backyard at the same time that the two were playing their game, Xaq suspected their game of being somehow responsible. This was, however, incorrect. (Series 2: "The Inexplicable Mountain")
- Keith was based on the real-life PCG creator and friend of the real-life Xaq, Keith Doomsday.
