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.
Dragon (magazine)
"Dragon" was the launching point for a number of rules, spells, monsters, magic items, and other ideas that were incorporated into later official products of the "Dungeons & Dragons" game. A prime example is the Forgotten Realms campaign setting, which first became known through a series of "Dragon" articles in the 1980s by its creator Ed Greenwood. It subsequently went on to become one of the primary campaign 'worlds' for official "Dungeons and Dragons" products, starting in 1987. The magazine appeared on the cover as simply "Dragon" from July 1980, later changing its name to Dragon Magazine starting November 1987.
