Mystra is the goddess of magic and with that the god of possibilities, which makes her arguably the most powerful deity in Faerûn. She is said to have taught the first spellcaster of the Realms, and to have enabled many of the races to use magic. She is most venerated by wizards and those who use magic or magical items in their daily use. Mystra provides and tends the Weave, the conduit to enable mortal spellcasters and magical crafters to safely access the raw force that is magic.
