get the Forgotten Realms. RA Salvatore took Greenwood's world and created characters and stories for it that made him a bestselling author and sustained TSR as a major fantasy book publisher." Publication history 1985–1990 In 1985, the AD&D module Bloodstone Pass was released by TSR and is retroactively considered to be a part of the Forgotten Realms, although it was not until the module The Bloodstone Wars was released that it became the official setting for the module series. Douglas Niles had worked on a trilogy of Celtic-themed novels, which were modified to become the first Forgotten Realms books, beginning with Darkwalker on Moonshae (1987). It is the first book in The Moonshae Trilogy, which predates the Forgotten Realms Campaign Set by one month. The Forgotten Realms Campaign Set 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 color maps, designed by Greenwood in collaboration with Grubb.

Some of the characters from Frank Mentzer's Egg of the Phoenix (1987) were incorporated into The Savage Frontier (1988). The compilation module Desert of Desolation was reworked to fit into the Forgotten Realms. The module Under Illefarn published in 1987 is set in the Forgotten Realms, as is the module released in 1988, Swords of the Iron Legion. R. A. Salvatore wrote his first Forgotten Realms novel in 1988, The Crystal Shard (1988), which was originally set in the Moonshae Islands before being moved to a new location and introduced the drow character Drizzt Do'Urden. Drizzt has since appeared in more than seventeen subsequent novels, many of which have appeared on the New York Times Best Seller list. In 1988, the first
