A war game set in Greg Stafford's world of Glorantha, wherein players move armies composed of the five tribes of Prax--the Bison, the Morokanth, the Sable, the Impala, and the High Llama. The explanation of the game in the original rules describes it such: "This game is the second of an interlocking triad of fantasies which deal with various aspects of man's magic and his relationship with the gods and the unknown." The first was Dragon Pass, while the third, Masters of Luck & Death, was never published.

Originally published by Chaosium in 1977 as Nomad Gods, the game was massively revised for a French language release by Oriflam in 1994, which has a more solid game system and much higher quality components.
