Scouts mention work crews here and there, operating bizarre contraptions and clanking, chattering, whirring machinery to measure, harvest, and parcel the resources of the Dell, living and dead. They cloak themselves in camouflage gear, and seem to appear and disappear from the shadows. Some appear human, others orruks and even grots.
Some shadier characters might recognize them as “evidence removers”, although for whom is anyone’s guess: they don’t seem to operate like one of the exploring warbands that are scattered around the Dell. Often the blame for the odd trap left here and there, and scores of missing gear from encampments, falls on them. They seem to know their way around this broken place, and operate with exacting purpose before leaving. Bad news to see these folk out here. Gotta be something going on.
