From publisher blurb:
Thennla is a fantasy setting for the Mythras game system.
Encircled by the Outer Ocean, watched by the God of the Sun and the Goddess of the Moon, Thennla's continents reveal themselves. The jungles of Jandekot; the vast deserts of Rasputana; and there, in the east, the Moon Goddess Jekkara anchored over it, is Taygus, land of plains and hills, the great inland sea and teeming civilisations. Here empires are born: Korantia, fading now, but defiant, its city-states each a goddess incarnate; the Jekkarenes, oldest of all civilisations, and blessed by the Moon Goddess; and now the Taskan Empire, overturning centuries of tradition with new ideas, ruled by a god-emperor and his avatar, the Iron Simulacrum. And watching closely is Assabia, a land of cruel rites and cunning sorcerers.
