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.

Ravens Bluff was for many years home to the RPGA's Living City role-playing campaign—a part of their Living campaign—and the site of the Living City series of game modules. The campaign was first proposed by then-RPGA Coordinator Penny Petticord in "Polyhedron" magazine issue #25 and ended in 2004.
