Magic

Magic is the ability possessed by some individuals to manipulate the ambient energies of the world to produce desired results. In Realms, magic is commonly referred to as "the Art".

The goddess Mystra controls the Weave which is what powers the magical energies of Abeir-Toril. The goddess Shar has control of the Shadow Weave which flows in-between the normal weave and enables the use of Shadow Magic.
