Professor Barker created one of the first roleplaying games, Empire of the Petal Throne, and has authored several fantasy / science fantasy novels based in his associated world setting of Tékumel.

Professor M.A.R. Barker devoted over 50 years to creating the World of Tékumel, developing it into a vivid science-fantasy setting with rich backgrounds and unique cultural identities. Inspired not only by the pulp SF and fantasy of the mid-20th century, but also by the rich civilisations of Moghul India, Ancient Egypt and he Aztecs, Tékumel sets the stage for a role-playing experience unlike any other.
