Ghouls are creatures of the Nevernever, and have made their way into Las Vegas, where they have taken up residence in the many washes that run through the Las Vegas Valley. The patriarch of the Las Vegas clan of ghouls is Joe Mercado, who has a sort of mafia boss rule over the members of the clan. It is unknown, however, whether he is the actual leader of the clan, or if his wife Evelyn has the final say in matters concerning their race.
On the surface, Joe and Evelyn Mercado run Mercado’s Corporate Salvage. They appear to be regular mortals, but are well known within the supernatural community as free-agents who will do dirty work for hire.
While nowhere near as large as the LaChaise clan, the Mercado clan is large enough to encompass the entire Las Vegas Valley, with a few stray ghouls who have taken up residence as close as Blue Diamond, and are encroaching on the Las Vegas population.
