Ed Greenwood began writing stories about the Forgotten Realms as a child, starting at the age of 8. : 72 He came up with the name from the notion of a multiverse of parallel worlds; Earth is one such world, and the Realms another. In Greenwood's original conception, the fantastic legends of Earth derive from a fantasy world that can no longer be accessed. Greenwood discovered the Dungeons & Dragons game in 1975, and became a serious role-playing enthusiast with the first Advanced Dungeons & Dragons (AD&D) game releases in 1978. Greenwood brought his fantasy world to the new medium of role-playing games when a university student named September introduced him to AD&D. : 72 The setting became the home of Greenwood's personal campaign. Greenwood began a Realms campaign in the city of Waterdeep before creating a group known as the Knights of Myth Drannor in the Shadowdale region. Greenwood felt that his players' thirst for detail made the Realms what it is: "They want it to seem real, and work on 'honest jobs' and personal activities, until the whole thing grows into far more than a casual campaign. Roleplaying always governs over rules, and the adventures seem to develop themselves. " Greenwood has stated that his own version of the Forgotten Realms, as run in his personal campaign, is much darker than published versions.
