It had no hull, or at least very little of one. Instead there was a reinforced wooden base, and a scaffold of struts that composed a kind of empty cage. There was a clockwork engine aft, which two men wound by pedalling furiously, and somewhat stubby wings that bore twin propellers. Thalric had boarded along with a pilot-engineer and Lieutenant te Berro, Fly-kinden agent of the Rekef, who was to brief him. Then the Cloudfarer had lifted off, a fragile lattice of wood shuddering up and up through the air under the impelling force of her propellers. Up and up, rising in as tight a spiral as her pilot could drag her into, until they were sailing across the clouds indeed, and higher. Then the pilot let go the struts to either side, and the Cloudfarer’s vast grey wings fell open left and right, above and below, and caught the wind. The vessel that had seemed some apprentice’s mistake was abruptly speeding over the world beneath it, soaring on swift winds westwards until they were casting across the Lowlands as high, it almost seemed, as the stars themselves sailed.

And it was so cold. Thalric was muffled in four cloaks and layers of woollens beneath, yet the chill air cut through it all, an invisible blade that lanced through the open structure of the Cloudfarer and put a rime of white frost on him, and painted his breath into white plumes before the wind whipped it away.

They would reach Collegium faster than any messenger, eating up any lead that Stenwold had built, so that despite Thalric’s detour to Asta it was anyone’s guess who would arrive first. They were so high, up in the very icy roof of the sky, that no flying scout would spy them. Even telescopes might not pick out their silvery wings against the distant vault of the heavens.

And as he suffered through this ordeal, from the cold and the wind, he hunched forward to catch te Berro’s fleeting words, for these were his instructions, his mission, and he would need to remember them.
