There are four types of magic known.
Elemental:One of two ancient magics. When Mithrune created the multiverse, he created the elements to give himself building materials. Each of the elements correlates to a state of matter. Earth=solid, water=liquid, air=gas, fire=energy. Each element is overseen by an elemental lord, with an army of elementals under their command. These elementals can give power to those who agree to act on the elementals behalf.
Demonic:The second ancient magic. As Pentox rampaged across the multiverse, shard of him broke off, becoming demons. These demons were later imprisoned, but still manage to slip through the cracks. This lets their destructive power seep through, corrupting anything it touches.
Arcane: A latent energy in the universe, mana can be manipulated to perform arcane magic. The most famous users of arcane magic are the Manatwisters. Arcane magic's two big fields are constructs/enchantments and raw attacking power. It is created when Mithrunic an Pentoxic power combine. They neutralize each other, creating a simple powerful energy.
Divine: Whenever a race reaches sentience, a diety is created to safeguard the new species. Only the elemental lords and other gods can create these dieties. These gods are a well of divine power to their mortal charges, who acess this power through intervening angels. The angels have portions of the god's power, and give it to priests/clerics/divine casters. However, different gods have different opinions on how much power to give. Some gods are reluctant to give any magic, while other make sure their followers are never without it. The lizardman gods are generally of the opinion that the power should be earned with an easy test. Or in desperate need.
