The Great Flood

The Great Flood was the massive deluge that wiped out the civilization of the Ancients. It drastically transformed the worlds geography, environment, society, and population. The Flood was started when the Ancients careless ambitions tore a great hole in the sky, allowing the sun to drastically raise the temperatures. This quickly melted the worlds glaciers away into the rapidly rising seas.

Most of the ancients great cities were swallowed by the expanding ocean, and all of the worlds lower lands disappeared forever, lands only vaguely remembered by those of the salvage age as long lost lands that were swallowed by the sea.
