She uncovered Foxen and went to look at the leak again. The air was still hot and thick with wet, so she went back to her sitting place where there was nothing to do but fidget and worry. Auri considered running back to fetch the brazen gear. Then at least she would have company. But no. She had to stay.

A leak was bad. But a leak might go unnoticed for some time. Now, with the water to this piece of pipe turned off entire, there was every chance that something vital up above was all alack. No knowing what. The pipe could lead to some disused piece of Mains, where it could stay dry for years with no one anyways the wiser.

But perhaps it led to the Master’s Hall, and right now one of them was halfway through a bath. What if it led to Crucible, and some experiment left to calmly calcinate was instead undergoing unintended exothermic full cascade?

It led to the same thing. Upset. Folk finding keys. Folk opening doors. Strangers in her Underthing, shining their unseemly lights about. Their smoke. The braying of their voices. Tromping everywhere with hard, uncaring boots. Looking at everything without a single thought of what a look entails. Poking things and messing them about without the slightest sense of what was proper.

Auri realized her fists were knots of knuckle white. She shook herself and stood. Her hair hung lank around her head.

The air was clearer now. Not wet and steaming any more. She gathered up her tools and was glad to see the steampipe had finally roasted both itself and everything around it dry. Better still, the slow regard of silent things had wafted off the moisture in the air.

Auri brought Foxen close to the black iron pipe, and was relieved to see the trouble was no greater than a hair-thin crack. Though the pipe looked dry, she wiped it with her handkerchief. Wiped it again. Then she unstoppered the bottle, dipped her brush, and spread clear liquid all across the tiny break.

Wrinkling her nose at the knifelike smell, Auri dipped her brush again, painting all around the pipe. She grinned and eyed the bottle. It was lovely. Tenaculum was tricky stuff, but this was perfect. Not thick like jam, not thin like water. It clung and stuck and spread. It was full of green grass and leaping and… sulphonium? Naphtha? Hardly what she would have used, but you couldn’t argue with results. The craft employed was undeniable.
