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.

The "Forgotten Realms Campaign Setting" won the Origins Award for Best Role-Playing Game Supplement of 2001. It made the Amazon.ca bestseller list at number 47 in September 2002. Reynolds identified the "Forgotten Realms Campaign Setting" as his favorite individual product from throughout his career, stating that it "was a huge amount of work but was so worth it because it is a great product". In May 2003 his book "Races of Faerun" (co-authored with Matt Forbeck, James Jacobs, and Eric L. Boyd) landed on the same bestseller list at number 42.
