A prehistory you were never taught.
Twelve thousand years ago, before the ice let go, the world wasn't empty, and it wasn't simple. Many kinds of people shared its coasts and trade roads: the broad-browed Alban Orves, who kept a continent's ledgers without writing a line of them down; the long-lived Annu; the small, sharp Oobins. Then a comet came, and the sea took the maps.
Deluvia is that world, built one piece at a time.
The comet comes from a real argument. Whether fragments of one struck the northern world as the last ice age ended, the Younger Dryas impact hypothesis, is still fought over by scientists. The atlas walks it strike by strike, with the papers on both sides: Firestone, Kennett, Sweatman, Holliday. Follow the strikes on the map →

Walk the world before the flood.
Six places, as they were twelve thousand nine hundred years ago. Each one leaves a fragment behind, and beside each fragment, the real evidence that the world under the sea was not empty.
