Magic is a science. My great grandma told me I' d appear and disappear if I understood the truth about illusion. As a Kid I did try to disappear/ appear. It only worked with a deaf-blind audience. I'd forgotten the penance part for a hundred years standing on one leg facing east. So I waited. My protagonists and antagonists can appear and disappear at will and I am proud to say I made them do it. They were good students though Its my first book and I still am editing it. Vadhan
