wood that I was going to work with. I didn’t want to waste the effort, so I was using the demo to start on the chest I’d promised the sutras I would make to hold them. It was going to be only just large enough to hold the one book: aside from conveying how special they were to me, I needed it to be light enough for me to carry out of the graduation hall next year. Aadhya and I had worked out a design that would end up shaped like a slightly larger version of the book itself, only carved of wood, and she’d given me a really nice piece of purpleheart wood to make the spine.
“I’m going to use the spell to liquefy the lignin in the wood, so we can bend it into a curve,” I told everyone, and passed around the wood so they could all make sure it was real and actually the perfectly straight and solid piece of half-inch-thick wood that it appeared to be. When it got back to me, I held it in my hands, visualized, and recited the incantation. Aadhya had told me lignin was just the bit in the walls of wood cells that makes them hard, and I’m guessing it wasn’t a huge amount of stuff that had to be changed, but even so, it was amazing how little mana the spell needed. It didn’t even consume half of what I’d raised, and the wood literally went pliable in my hands. I bent it over the wide steel pipe we were using to shape it, and Aadhya and I clamped it into place; then I used the spell to make the lignin solid again. We unclamped it and just like that, the plank was a tidy curve; the spine of the sutras nestled into it beautifully. The whole thing took only a few minutes.
Everyone was murmuring and excited as we passed the curved plank around. For the second demo, Aadhya used an engraving tool and carved a little design in the very top of the plank, then set up a tiny funnel with a strip of silver out of her supply stash. I turned the silver liquid, and she poured it into the design. I even experimented a bit: I tried turning it back solid in a continuous process, just as it landed in the carving, so that it wouldn’t overflow the edges. It worked brilliantly.
People started asking if I’d show them something more, and I didn’t see any reason not to: I still had some mana left. Aadhya and I were trying to decide what we should do, and then a senior girl in the alchemy track suddenly came up with the idea of trying to turn some nitrogen liquid, straight out of the air around us. That could obviously be amazingly useful, although we weren’t sure what would happen with the nitrogen after I did it: wouldn’t it just instantly evaporate away again? But everyone was so excited about the idea that a couple of senior boys volunteered to climb up on a bench to get one of the metal canisters from the high shelves along the wall, if we let them keep whatever was left inside after. I agreed; that was fair when they’d be the ones sticking their heads that close to the ceiling without knowing if there was going to be any real return.
The first one climbed up, and then the next round of grinding vibrations hit, except this time it didn’t stop; instead it got worse, a lot worse, almost graduation-day bad, and things started falling off the walls and shelves and then even the stools started falling over. The boy on the bench had crouched down for balance already, but he had to jump for it, grabbing for his friend’s hand just in time as three of the canisters came crashing down on the table. One popped open and a writhing mass of baby copper-gnawers came spilling out on the floor, like the unwanted prize in a shell game.
But we were all running for the door by then. Thankfully I had never taken the book-sling off. I grabbed the newly inlaid spine of my chest on the way, and Aadhya and I made it out into the corridor in the middle of the pack of fleeing kids. We all dashed for the stairs. Getting to higher ground is the sensible thing to do when there’s a disturbance from below, so
