Freelancers of Jackson's Hole
The Black Wings are a band of Nomads that roam the wastelands surrounding Jackson's Hole. For years they scavanged in small groups to gather water or food, but in the last year they're numbers have been growing and they have become bolder making brutal attacks on travelers coming to and from Jackson's Hole through the Wastes. They have also made a couple raids against settlements and attacks on smaller bands of Nomads and rumor has it they are being lead by a charismatic and brutal warlord who has convinced other bands to join his.
They have some vehicles and they are known to be ruthless and brutal, and like some of the worst Nomad bands, people whisper they are cannibals.
