The Elemental Planes
The Elemental Planes are where most magic is drawn from. They were created by the first wizards, namely the Weave Keepers, in an effort to remove the volatility from magic. They traveled to the Plane of Elemental Chaos, which was the result of the Primes purging the Elemental chaos from the The Material Plane. They're divided into 3 categories, The Natural, the Arcane, and the Divine.
