"Sorcery is prettily simple. I do need to look up how to do something I've never done before, it took me weeks to learn to make gates - and the notation for harmonic mapping is a nightmare - but the basic concept is straightforward: know what you're doing and what you're doing it to, and it'll happen, no materials or awkward sacrifices or treating with third-party entities or particular risk of backfire. Unfortunately, it has some major gaps in its possible applications - fairies have been working on sorcery for a long time and new advances are rare and esoteric in recorded memory; it is likely that we know already how to do all of the things the system can do, at least without cheating via harmonics in some way. It is difficult to use in unfamiliar territory, on short notice, in opposing someone who thinks faster, or in opposition to a specialized fairy kind magic; I don't know how it stacks up against mud-and-sticks-and-glitter. It can't do anything about orders except that if you know someone well enough to do mental sorcery on them you can make them forget their orders and wind up in a loop trying to recall what they were, and similarly mental sorcery could delete a name from someone's head."
