I am Mystra. I am the Lady of Might and the Mistress of Magic! I am Power Incarnate! Wherever magic is worked, there am I – from the cold poles of Toril to its hottest jungles, whatever the hand or claw or will that works the sorcery! Behold me and fear me! Yet behold me and love me–as all who deal with me in honesty do. This world is my domain. I am magic, mightiest among all those men worship. I am the One True Spell at the heart of all spells. There is no other.
— The Mother of All Magic
