Sorcery is Magonomia’s term for the Ars Goëtia, the art of conjuring spirits (and binding them to service). Such spirits include faeries, elemental spirits, ghosts and ghosts, as well as the mysterious, invisible spirits that classical magicians called daemones. Conjuring such spirits is dangerous and widely feared, but many a magician is willing to resort to sorcery for the overt power it provides. Sorcery offers powerful spells such as glamours (a form of illusion), curses, invisibility, even calling down bolts of lightning from the sky! Sorcery is usually neither subtle nor very safe, but it is definitely effective.
The updated Magonomia spell lists now include all the Sorcery spells that will be in the core book.
