Tethys is not a fantasy world. It is Earth — a version of it — older, wetter, and operating under systems that predate the ones we built to replace them. Sky City clings above the Weep on ledger math and pressure engines. The corridors below carry creatures, weather, and older records. The book begins where two of those systems fail at once.
