Very well, then-it's very technical, so I'll do my best to make it as easy to understand as possible.
[...because really, he's not expecting this person to know anything about magic, and that has a pretty good tendency to kick him into condescension mode...]
In my world, it's known to a select group of people that an infinite number of parallel worlds exist, ranging from ones where the only difference is that one person turned a different direction at an intersection to ones like... well, this one, basically. It's impossible for most people to move between these parallel worlds, obviously, due to the fact that it requires True Magic to do so.
There's only one person who's actually achieved it, and most of his attempts to take on students lead to them returning as gibbering messes, so it's highly unlikely that someone else has figured out how to accomplish the same thing. While he's a troublesome individual, I've never heard anything about him doing something like this-that, and the phenomenon seems to be intimately connected to this world, so it's probably something that exists here causing it.
