Vi and Ariel entered the part of Laketown that had grown on the shores by the bridges, but all the merchants seemed to be huddled in their daub-and-wattle homes, with their chimneys or chimney holes smoking.

“By some ancient magic we still can’t duplicate, the islands are actually floating,” Sister Ariel said. “The entire dam can be opened and the islands flushed out into the lake in times of war. Of course, we haven’t had to do that for centuries. And a good thing, too. I understand towing all the islands back up here is a lot of work.”

“It’s beautiful,” Vi said, forgetting herself. “The water’s so clean.”

“This city was built at a time when magic was used to benefit farmers and fishermen. There were special streams in every city that would take the stains out of your clothing. There were plows that could be pulled by a single ox that would break six furrows in a single pass. There were free public baths with water as hot or cold as you wanted. Charms that kept meat from spoiling. People thought of magic as a tool, not only as a weapon. In Laketown, the slops and nightsoil are supposed to be thrown into these pipes that—see, no smell?—that take them directly to the dam. Of course, you can never get everyone to obey even a sensible law—like not throwing nightsoil in the water you drink—so the lake itself has spells that cleanse it.”

Sister Ariel led them to a white punt on the far end of the dock. A boy dodged out into the rain to take their horses and Vi took her bags and stepped onto the punt. She took some comfort in Sister Ariel’s obvious terror that the boat was going to capsize. As soon as they were settled on the low, wet seats, the punt began moving by itself.

Vi grabbed the side of the boat in a white-knuckled grip.

Sister Ariel smiled. “This magic, on the other hand,” she said, “we can do. It’s just too much trouble, these days.” They skimmed quickly into the wide water streets and the little boat turned on its own.

“There are currents that shift on the turning of the glass. If you know what you’re doing, you can get from one side of the city to the other going downstream all the way.”

After a few minutes, they emerged into an enormous opening with no islands except the biggest one of them all. “Behold the White Lady. The Alabaster Seraph. The Chantry. The Seraph of Nerev. And for you now, Vi, home.”
