The Grand Lodge of the Frontier, The Frontiersmen's Lodge, or simply The Frontiersmen, are an independent band of mercenaries, hunters, and explorers that have been operating in the former Northern Commonwealth since their founding in 2231 by Willow T. Grier. They have been in numerous skirmishes with the region's tribals and raiders, most famously in their campaign against Denga Badtusk's Horde from 2254 to 2257. Since then, they have slowly expanded their operations into Idaho, most notably, New Twin Falls.
