I'd also like to know the extent and types of magic allowed.  Of course, I'm not asking about how powered up magic can get come meta-game, but more like the strains put on a person for type X or Y.

Magic and super natural arts is one of the areas I have not completely explored yet but this much I can tell.

Strength of one's art depends on his or her faith - understanding and knowledge of matter, unwavering trust that matter will heed when it is commanded. Using supernatural skills strains stamina. Running out of stamina means fainting, black out, coma of a kind depending of how severely the individual in case has been exhausted.

The most basic magic is natural magic, ability to control the elements - the natural world around you. For those who have made an extra effort towards light or dark, there is a possibility to add some extra flavor.

Alchemy, necromancy, and summoning are possible. A word on summoning. Because the embodied spirits have a will of their own they can't be commanded, only called. To become a summoner one must find the spirit, challenge the spirit's test, win and make a covenant with it. Loyalty to the covenant is the key to the relationship's strength.

Other forms of magic and supernatural arts are possible except those involved with space and time.

Anything else someone is wondering? :)
