Is there a type of magic that isn't straight up evil and doesn't require you to sell your soul?  every intent we hold, even every thought we think, esp. when its emotionally charged, is magic.  we are creators of our reality. magic is not good or bad per se, its a completely natural thing that we do all day long.    thing is, the clearer the intent, the stronger the command.  the more people align with the intent, the stronger the magic. add inter- or extra-dimensional forces to it - call on demons or angels, call on moloch or god -, and the intent gets amplified and is more likely to manifest.
