Faerûn

The most used campaign setting of all time. The Forgotten Realms is a fictional alternate world that has been published as a campaign setting for Advanced Dungeon & Dragons (AD&D), Dungeons & Dragons (D&D), 3rd Edition Dungeons & Dragons (3e), and 4th Edition Dungeons and Dragons (4e), by TSR, Inc. and Wizards of the Coast (WotC). The setting is also referenced in the 5th edition Dungeons and Dragons core books, though it has not yet been published as its own separate setting.   It was originally created in 1967 as a setting for short stories by Ed Greenwood, but it has since become one of the most enduring campaign settings for D&D.   The primary focus of the setting is the continent of Faerûn, part of the world of Abeir-Toril, an Earth-like planet with certain obvious influences and similarities from the real world and fantasy fiction.
