Adventures on Tékumel is a complete roleplaying system.
The series of solitaire adventure books are designed to give the player an introduction to the culture of Tsolyánu and Tékumel in general. The player's character is developed as the player learns about the setting.
Gardásiyal: Deeds of Glory is the core rule set for the role playing game, as played with a game master/referee. The rules in the solitaire adventures are very simple and not the same as those used for the full role playing game. Conversely, Gardásiyal doesn't have a character generation system; Part One: Growing Up in Tsolyánu is required in order to create characters. The solitaire books provide character generation combined with necessary information about the setting.
The Tékumel Bestiary provides descriptions and statistics for use with Gardásiyal: Deeds of Glory, the core rules for the system. The creatures of Tékumel are unique to this setting and this book is necessary for the game, particularly if the game master is unfamiliar with the Tékumel setting.
