Sundaland, the Immense Continent that was above water before the Deluge that Ended the Last Ice Age.

This immense Continent was Submerged after the Cataclysm that happened ~11,600 years ago ending the Last Ice Age.

A very different geographical world was revealed because the Sea Levels were roughly 100 meters lower than today.

Sundaland was as big as the whole of the United States, including Hawaii and Alaska.
