Mystra

Mystra (pronounced MISS-trah ), the Mother of all Magic, was the greater deity who guided the magic that enveloped Toril prior to the Time of Troubles. Mystra tended to the Weave constantly, making possible all the miracles and mysteries wrought by magic and users of magic. She was believed, as was her predecessor Mystryl and successor Midnight, to be the embodiment of the Weave and of magic itself. Mystra's symbol was a ring of seven stars surrounding a rising red mist, spiraling to the heavens, though her older and more often seen symbol was a simple seven-pointed star. Her divine realm resided in Dweomerheart.

Worshippers
The church of Mystra preserved magical lore so that magic would continue and flourish in the future even if the dominant races of Faerûn were to fall. Its members also searched out those skilled in magic or who had the potential to use it, keeping a close eye on those who were likely to become skilled. Her clerics were encouraged to explore magical theory and create new spells and magic items. Sites dedicated to the goddess were enhanced by the Weave to allow any spell cast by her clerics while in them to be affected by metamagic.

Mystra's Chosen
Mystra also had powerful mortal servants among her ranks of followers, including Elminster, Khelben Arunsun, the Seven Sisters and the mad lich Sammaster.

Orders

 * Order of the Starry Quill
 * The Starry Quill was an order of Mystran bards who often worked as information gatherers and rumor-mongers for the church or spent part of their time in designated libraries unearthing magical knowledge and then preserving it for posterity.

The Church of Mystra sponsored an order of rangers, known as the Order of the Shooting Star. These rangers received spells from Mystra and served as long-range scouts and spies for the church, also dealing with magical threats that imposed upon the natural order of things, such as unloosed tanar'ri and baatezu as well as creatures born of irresponsible wizardly experimentation.
 * Order of the Shooting Star:


 * Knights of Mystic Fire
 * The Church of Mystra also sponsored a knightly order of paladins called the Knights of the Mystic Fire, who were granted their spells by Mystra. They often accompanied members of the clergy on quests to locate lost hoards of ancient magic and also formed the cadre from which the leadership for the small groups of armed forces who guarded Mystra's larger temples and workshops were drawn.

History
The goddess of magic has had three incarnations over the years. All shared the same role and responsibilities, but they were different in alignment and temperament.

Mystryl
Mystryl, as her predecessor and first incarnation was called, was the goddess of magic and a chaotic neutral greater deity born during the battle between Shar and Selûne at the dawn of time. Being the goddess of magic, spells, creativity, invention, and knowledge, she was said to have taught the first spellcaster of the Realms. All spells of all types were known to her when their creators constructed them, and her spirit was said to imbue all inventors, authors, songwriters, and artists. She was most venerated by wizards and those who used magic or magical items. She provided and tended the Weave, the conduit that enabled mortals to safely access the raw magic force.

Mystra
Mystra came into being after the previous incarnation sacrificed herself in -339 DR to save Faerûn from the destruction Karsus of Netheril nearly brought upon them. She used as a basis a beautiful peasant girl who was still just learning cantrips but who had the potential of becoming an archmage. She was Lawful Neutral in alignment.

During the Time of Troubles, Mystra was killed by the deity Helm for defying the god and trying to climb the Celestial Stairway to the heavens. Her death caused great damage to the Weave, but the young mortal Midnight was chosen to succeed the goddess as the next Mystra — eventually restoring the magic of Toril.
