Which classroom this had been originally (that is to say, just a few months ago), Kiri couldn't even remember - in the course of this term's flooding, the classrooms and offices had been moved around as if the whole castle was being shaken by some sort of mad titan - but it was empty except for one table at the opposite end. Professor Lawson was sitting on it with an air of quiet contentment about him.

"Hello, Professor," said Kiri, and she walked off to one side to deposit her bag on the ground as instructed. Having done so, she wandered back into the middle of the room, wondering what to do with herself until the lesson started.
