In February 2005 Guardians of Order (GOO) issued Tékumel: Empire of the Petal Throne, the fourth-generation in Tékumel role-playing games. Using GOO’s Tri-Stat rules and a highly sophisticated character generation system, this core rulebook introduces players to the land, history, and inhabitants of Tékumel; and gives the gamemaster the tools needed to develop and run epic campaigns or single adventures.
