Vortex of Mortal Magic
Sorcerers, Wizards and Bards of the mortal races draw their power from an invisible vortex of energy that permeates the entire world of Avlis, called the Vortex of Mortal Magic. The god Andrinor is the only known individual to succeed in controlling the Vortex of Mortal Magic, and thus, it is now he who determines which individuals have access to it. As the god of magic, all wizards acknowledge him as being in control, and most, though not all, ascribe loyalty to him because he is now the source of their power. Another deity, Angadar, is the god of Arcane Knowledge, and is credited with the power for Arcane advancement. It is Angadar who gives the ability for Mages to scribe scrolls, and to understand the scrolls' meaning. Wizards respect Angadar as their source of Arcane Knowledge.
Vortex of Deific Magic
Deities, clerics, spirits, and other divine beings draw their magical energy from the Deific Vortex. This vortex is controlled by no single god: Every cleric who wants access to such a Vortex will have to go through her deity. However, for cantrips and slightly more difficult spells, (Level 3 spells and under) there almost always is some other god who will hear your prayers as a deityless cleric. For more powerful spells, above level 3, a cleric needs to have a single specific deity. In game, this means there must be a (correctly spelled) deity in your deity field when you cast a spell of higher level than 3, and you must have exactly the same alignment as your deity. You can change your deity field either in game or at character creation.
