Kiri looked around the restored Great Hall with huge eyes. Just hours before, if she'd understood the frantic and excited reports of her classmates correctly, everything had been submerged, and now the 'Hall looked as if nothing had happened. The ceiling showed the sky, like usual. The tables were all there, and the benches, too - of course, Kiri thought wryly, those were so hardened by now they'd probably survive the Universe. But they were clean. No algae clinging to anything, no... water spots or whatever was appropriate damage in those circumstances. No sunken ships or buried treasure, either.

It felt oddly like her first day again to Kiri as she stumbled towards the bench for the third year students. She kept twisting her head and looking around. How bizarre. She tested the bench with her hands before sitting down. It wasn't even wet. She sat. The Headmaster stood at the front, surveying the 'Hall.
Kiri was looking at the points of the four houses, wondering how they'd fared underwater, when, behind her, people started shuffling and muttering in surprise. She turned around. There was... water. On the floor. Water.
