Forgotten Realms
The "Campaign Set" (often referred to as the "Grey Box") was later released in 1987 as a boxed set of two source books ("Cyclopedia of the Realms" and "DM's Sourcebook of the Realms") and four large maps, designed by Greenwood in collaboration with author Jeff Grubb. The set introduced the campaign setting and explained how to use it, and reserved space on the map for SSI's Gold Box computer role-playing games set in the Forgotten Realms.
Forgotten Realms: Demon Stone
Forgotten Realms: Demon Stone is a video game that was released in 2004 for PlayStation 2, Xbox and Windows PC. It is set in the Forgotten Realms campaign setting for "Dungeons & Dragons" (D&D), but the gameplay only vaguely models D&D's structure. The story was written by R.A. Salvatore and features the voices of Patrick Stewart as Khelben "Blackstaff" Arunsun and Michael Clarke Duncan as Ygorl.
