N'wah's Iron Gods Campaign
The barbarian tribes of Numeria are nomadic, with two notable exceptions: the Blades of Aaramor and the Sunder Horns. Save for the brutal Sunder Horns, the tribes generally maintain an uneasy truce with each other as well as Numeria’s settlements, as outright warfare undermines everyone’s survival and inhibits trade for those items a tribe can’t produce on its own. Crusaders are usually left unmolested, and some tribes accept bribes of goods from foreign merchants in lieu of putting them out of business or slaughtering them outright. Most tribes take thralls, but may release them after a season or two of labor, or even adopt them if they’re found worthy.
