of the Forgotten Realms is detailed: "Azuth serves Mystra. Mystra and Selûne have a mysterious connection ... and Mystra often works with Oghma and his gods." Mystra is most commonly worshipped by magic-users of any alignment, and characters working as sages. Mystra later officially appeared as one of the major deities for the Forgotten Realms campaign setting, in the Forgotten Realms Campaign Sets "Cyclopedia of the Realms" booklet (1987). Advanced Dungeons & Dragons 2nd edition Mystra was described in the hardback Forgotten Realms Adventures (1990), the revised Forgotten Realms Campaign Setting (1993) in the "Running the Realms" booklet, and Faiths & Avatars (1996). Her clergy was further detailed in Warriors and Priests of the Realms (1996), and Prayers from the Faithful (1997). Her role in the cosmology of the Planescape campaign setting was described in On Hallowed Ground (1996). Her relationships with the nonhuman deities in the Forgotten Realms was covered in Demihuman Deities (1998).

Mystra is listed as the goddess of magic for the Forgotten Realms setting in the Player's Handbook (2014). The Sword Coast Adventurer's Guide (2015), a campaign setting guide, includes information on the worship of Mystra and on her connection with both magic and the Weave.
