For what little there is, the magic in this world can be broken down into two categories: demonic, and divine.
This is the most common sort of magic, and unfortunately the most dangerous. A person, who is inherently of this world and thus material, shares his (or her) body as a house for an incorporeal denizen of another plane of existence. With the powers of a demon, they can perform all sorts of vulgar magic – commanding beasts, dominating the wills of others, even hurling elemental forces at their opponents. Its scope is more limited than divine magic. A demon can blow something up, create disorder and chaos, but it cannot make things whole again. This magic comes at a steep price – the more magic a sorcerer uses, the more the demon learns of this world. When it is strong and smart enough, it will test the prowess of its mount and try to take control. Once it succeeds and ascends at the primary force, there is little left of the person. The sorcerer is then immediately sundered, losing his chance at heaven and a place by his god forever.
A sorcerer can hide his cohabitant, and escape the scorn of those around him for his illicit trade. Sorcerers, if they are found, are subjected to all the traditional “sure-fire ways to kill a witch.” Drowning, burning at the stake, burying in a catacomb, anything violent and unpleasant. What the uneducated don’t realize, though, is that they may have killed the person, but the demon will just leap to whatever life-form is nearby and escape in it.
Ultimately, most who seek out demons to control them and use their powers end up being the ones controlled. There are a very few exceptions, though, in the Temple Sorcerers. Through special training, coupled with carefully cultured demons handed down through the ages, these individuals have learned how to use demonic powers for good. They are all god-touched in some form, too, or have an astounding force of will that is just as otherworldly.
Like demons, the gods are beings entirely of spirit, and can only affect this world if a being of matter if a mortal can open himself up as a conduit to the gods of his free will. With divine magic, all is possible. The gods do not like to meddle, though, and listen to all with equal care and concern. An explorer lost in a cave, praying for the guidance of the gods, will be just as likely for a ringtail cat to conveniently knock down some loose stone and permit sunlight to trickle down as the clergyman prostrate before an altar. One might have more practice at watching for signs of the gods, but both will be given the same love and attention.
There is quite a difference between an answered prayer and divine magic, though. In order to cast magic, which is basically a miracle, one must be completely open to their god. They must resonate with them – be selfless, have a soul of immeasurably depth and wisdom, and align with their god in the most crucial facets. One can be god-touched, housing miracles of the Daughter every day for a year, and then lose their ability to open to the god in an instant. It is a constant trial of meditation and compassion, to be able to wield divine magic. There are usually only a handful of saints in the world at one time, averaging one or two per god.
