My elf wizard, Eliphas Fumio, is in a post apocalypse world in which monsters and other things have spell resistance and immunity. The population for magic users is very low and so far, no magic schools. My character loves magic and he finds it very distressing that magic is almost a lost art. What would it take for Eliphas to build his own school and still travel with his party to undo this post apocalypse world? Note: there are towns, but they are few and in between.
