"The Indus Wilds are a range of mountains that form a barrier between two great nations. To the north, the Steel Empire rules over the wide steppes with an iron fist and a spiked boot. To the south, the Silk City States form a trade network that spans from the deserts in the west to the jungles of the south east.

​

Within the wilds themselves are the Wilder Societies. Nomads who have chosen to leave the security of Silk or Steel for the hardships and freedoms of the wild mountains. They cannot stand against an empire directly, but the terrain, their speed and their solidarity are their best defence. And if those fail there are the Relic-Mechs: combat walkers From the era before the End Time that broke the world - they may not be a match for an entire legion head-to-head but their lost technology and superior mobility makes them a thorn that is hard to ignore.​"
