When I checked my pockets and pack for anything that may give me at least some hint to whom I replaced. I found no identification. Just a set of filthy clothes, a box of something called matches and a few pouches of powder that when I tried to set aflame, started to spark into a variation of colors! Some colors I've never even been able to perform with my magic!
I gathered a crowd doing so. They started throwing coins and pieces of paper into my pack when I set it before me to do a few more tricks. Considering that I found myself to be pretty much coinless, this could be a perfect way to generate some income.
