The Black Market Guild is a loosely knit organization of adventurers that are skilled in the mercantile arts as well as self defense. They come to the aid of fellow guild members and provide information on buying and selling specialty goods on the black market.
Man that was pretty boring right? Here's the truth: The Black Market is for all you drug dealin', hooker stealin', skin peeling' heroes/heroines. Not only do you get what you want but you gave fun getting it. If you like stealing, drinking 'Snapple', or puppies! Join!
