Sandmen are drug pushers, specializing in a potent psychic drug called Nightmare. Retrieved from Tulpa excrement, and imprinted with horrid nightmares from individuals, Nightmare is highly sought after by drug connoisseurs. Nightmare literally gives its user a powerful nightmare, even over waking sensations.
Sandmen are a dedicated, ruthless, and anti-social lot, with their own subculture, slang, and code of honor. Few are willing to do the hard work required to prosper as a Sandman, although the financial rewards are great. Sandmen control the entire distribution network from procuring the raw materials to retail sales. Regular organized crime types are typically frightened of the Sandmen, who are physically dangerous but, more importantly, give regular crooks the willies.
