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 Heroes
In their original adventures prior to the "Crisis on Infinite Earths", the Forgotten Heroes are all superheroes who, at one point in their career, had discovered a mysterious golden pyramid. When they attempt to report the discovery, they find themselves censored by the US Government. The members of the team are brought together by Immortal Man, who reveals to them that the pyramids are the work of his eons-old foe, Vandal Savage. With the aid of Superman, the Forgotten Heroes destroy the golden pyramids and save the Earth.
