Sonderia
The world of Sonderia was once a lush fresh water covered world. The vast Sonderian Sea spread between the various island nations. Floating cities and boat communities were common place. The sea was abundant with food and nourishment. Then the Cataclysm happened and the Sonderian Sea disapeared. It didn't dry up slowly, it simply vanished leaving a dry desolate landscape that stretched endlessly.
