The realms, or realms of power, are the four dominant supernatural forces at work in the Mythic Europe of Ars Magica. There are usually said to be four realms of power: the Divine (God, angels, and faith), the Infernal (the Devil and demons), Magic (mystical workings and mysterious beings) and Faerie (the unknown world of the fey). The Mundane realm of the natural world and of non-magi is often described as a realm of its own, but not in the same context of the other, fundamentally mystical realms; rather, the realm of the Mundane is characterized by its lack of direct influence from the four realms of power. Thus, the Mundane can be said to be a realm, but it is decidedly not one of the four realms of power.
