In an attempt to reclaim the great Mississippi River for the progeny of mankind, the merchants and traders of the city of West Memphis, Arkansas, banded together to form the Mississippi Traders Union. The 'Muts', as they are called, are the vagabonds of the wasteland, as they get to travel many lengths of the Mississippi, learning from the tribals and settlements they encounter, sometimes even discovering some neat technology to sell or to keep for themselves. Although they are scattered across the Mississippi, some of them have formed their own groups, sometimes going rogue after a while, to accomplish more difficult goals in a coherent fashion.
