im not sure there is a word "no" enough for that. lol

even if matter could be created from nothing, or something as inconsequential as the conjurer's soul/energy, even if it was just a speck of dust in this story, that would be a bit far-fetched and OP. also, i assign the powers.

the best way to approach it is by making a boring mundane human character that can later develop. assume this is just a generic Mad Max or Walking Dead apocalypse RP with no supernatural crap. that will make it more exciting when something supernatural does happen
