abstract:In the World of Greyhawk campaign setting for the Dungeons & Dragons role-playing game, the River of Blood, or more properly, the River of Blood Murders, refers to the mass murder/ sacrifice of eight children of wealthy Greyhawk families in 565 CY by Sir Bluto Sans Pite, a local knight. The event was so named because Bluto performed the grisly ritual in a cavern beneath his home where the Millstream enters Greyhawk City, causing the stream to run red with his victims' blood.
