"Sorcery works by observing the setting and target and concentrating on how one wants it changed - and if the harmonics are loopy by mapping those and counting that under 'observing the setting', although you can dispense with that part if you're good enough at the rest. It rewards working on one's home turf. It can do things like growing plants, invisibility, setting things on fire, healing, turning people into frogs, transmuting materials, candying dewdrops, wards, gates, and traps. The local one or ones appear to be made of mud and sticks and glitter, require dramatically more per-spell but less per-location preparatory work and generally be more flexible about the prerequisites for a casting, and focus almost entirely on combat or at least conflict applications. If that was not editorialized enough to say what features I like, do say so."
