Magic is an energy that suffuses the multiverse and that fuels both destruction and creation. Gods of the Arcana domain know the secrets and potential of magic intimately. For some of these gods, magical knowledge is a great responsibility that comes with a special understanding of the nature of reality. Other gods of Arcana see magic as pure power, to be used as its wielder sees fit.
The gods of this domain are often associated with knowledge, as learning and arcane power tend to go hand-in-hand. In the Realms, deities of this domain include Azuth and Mystra, as well as Corellon Larethian of the elven pantheon. In other worlds, this domain includes Hecate, Math Mathonwy, and Isis; the triple moon gods of Solinari, Lunitari, and Nuitari of Krynn; and Boccob, Vecna, and Wee Jas of Greyhawk.
