Kaede's very unfamiliar with this feeling.
He doesn't have a whole lot of time in which to be unfamiliar with the feeling. Mundanely, it's like he's getting seized, very suddenly and unexpectedly, and yanked, by something all over his body, and in a direction that doesn't exist, a direction that seems to be orthogonal to all three normal directions. Which is odd in itself, but what's even odder is the magic that's doing it. It's really, really, really unlike any spell he has ever seen or felt. It's bigger, much bigger, and much more complex - much more complex even than the ancient artefacts they found, sometimes, more complex even than the golems.
He doesn't have a full second to appreciate this before his surroundings are whisked away - or, more likely, he's whisked away from his surroundings - and he finds himself elsewhere.
