abstract:In the World of Greyhawk campaign setting for the Dungeons & Dragons roleplaying game, the Millstream is a wide stream that runs north to south through the Free City of Greyhawk. The stream emerges from underground, beneath the former home of Sir Bluto Sans Pite in the High Quarter, across High Street into the Garden Quarter, then into Clerkburg, where it is straddled by the Bridge of Entwined Hearts.
