Reading just the core rulebook the guidelines seemed pretty clear to me. Using correspondence to teleport objects would be, at best, vulgar without witnesses. If you teleport you're gonna rack up some paradox. BUT, in How do you do that it talks about the Batman where you use the cover of darkness to essentially hide before you vanish such that any person nearby believes you to be basically sprinting away and hiding and thus the magic is coincidental instead of vulgar without witnesses. I'm trying to understand the system better and I can't understand why that should be any different from teleporting from one place with no witnesses to another place with no witnesses. Thanks!
