Empire of the Petal Throne – The World of Tekumel (1977 TSR 2nd printing) – NO BOX, softback roleplaying game, by M.A.R. Barker
“Rules for Fantasy Adventures and Campaigns on an Alien Planet
Tekumel, the world of fantasy and adventure. The setting for this fantasy campaign game is an alien planet, Tekumel, where a cosmic cataclysm stranded human and extra-territorial invaders eons past. A hostile world of poisonous flora and fauna, with intelligent and vengeful native races! Mankind and its allies must battle for survival with nothing save Medieval technology — but magic aids them . . . and there are certain supernatural powers which may intervene.
The game contains three large full-color maps and 8 1/4″ x 11″ book with a brief history of Tekumel, rules, descriptions of various races and creatures involved, and more. Share in this exciting fantasy world by playing EMPIRE OF THE PETAL THRONE.”
Depending on how you define “published”, this was arguably the second RPG ever published, and the second published by TSR. The first TSR printing was 1975. This second printing was 1977. (See here for an explanation of the very minor differences.)
The box is sadly NOT PRESENT in this copy. The rulebook is in FAIR condition. The reference sheet is in FAIR condition. All three maps are in NEAR MINT condition.
