I had a theory about the Snarl...

That happened in a crayon flashback, which implies some degree of unreliability and stylization.

Okay, so let's review the sequence of transmission. First, Soon saw what happened to Mijung. Then, he told Shojo about it. Then, Shojo told the Order. Where's the unreliability?

Maybe, but probably not. Not that it would matter; if Laurin's study pulled a part of it out through the rift, there'd doubtless be effects on the immediate surroundings.

Pulled what out of the rift? I thought your theory was that the Snarl was a metaphysical phenomenon, not a physical entity.
