A complete setting for Tékumel RPG campaigns!
Explore the fascinating Kúrt Hills region of the Empire of Tsolyánu, presented here in astonishing detail. Travle the mighty Sákbe Roads with the Grghúzh—the non-human Páchi Léi travelling folk! Battle cultists of the demon Bésh across Tsolyánu's Plain of Mists! Join—or oppose—savage Kurtáni in battle against servants of the Worm Lord! Face the secretive Under-People of the deep forest! There's enough here to entertain your Tekumel players for years.
