Magic is different depending on where one is, and the world in which they reside. There is a sort of universal magic that applies everywhere, its rules immutable and far stronger than any magic from which it descends. However, as elemental as that magic is, little can be done with it.

Universal Magic

1. All magic requires power, energy. Something cannot arise from nothing. 2. Knowing the name of something gives power over it. 3. All souls contain an essential vitality, energy, which can be used in the absence of any other power to fuel spells. 4. The transference of vitality from one thing to another requires, in at least some part, sacrifice on the part of the transferer.
