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.
Dungeons &amp; Dragons campaign settings
A setting inspired by the Arabian Nights mythos, with genies, elemental wizards, holy assassins, and a land unified by belief in the power of Fate. The land, named Zakhara, is located near the southern border of the continent of Faerûn, the main landmass of the Realms. However, "Al-Qadim" appeared under its own label, and not the "Forgotten Realms" label, unlike Kara-Tur and Maztica. This campaign setting is no longer officially supported; however, it is now regarded part of the Forgotten Realms campaign setting as its setting is mentioned in some Forgotten Realms sourcebooks and novels.
