Mystra

The Lady of Mysteries, the Mother of All Magic, Our Lady of Spells

Mystra is the weave that infuses everything in Faerûn with raw magic. Her clergy can tap into the weave and use its magical potential to cast spells and create items of great power. Though Mystra is inherently good, her magic can be used in many ways - sometimes for evil purposes. Her clergy is charged with preserving magic while guiding its use to advance the greater good.
Followers of Mystra celebrate the 15th of Leaffall, called God’s Day, which marks the return of the Lady of Mysteries to divinity. This is especially popular in Waterdeep, culminating in magical fireworks throughout the night. Follower initiations and weddings are celebrated by Starflight, wherein the honored individual(s) are given the power of magical flight while the stars that night are visible.
Magefire is a ritual of healing and reinvigoration; a participant is surrounded by a circle of Mystrans and infused with magical energy until surrounded by the glow of blue fire. It is an empowering ceremony that can also be used to remove some magical curses or conditions.
The House of Mysteries in Elventree (in the Dalelands) is a ruined hall of impenetrable magical darkness where travelers might implore the Voice of the Goddess, a specialty member of the clergy, for services. The Voice of the Goddess offers veiled information, magical identification, and even spells for those in need.
