The Nautilus System is ruled over by Lord Pontus, and contains a single habitable planet. This planet, known as Nautila, is covered almost entierly by oceans, with island and archipelagos scattered across the surface. These small land masses are home to tribal cultures of both humans and Ohne.

The main city of the planet, Triton, is located underwater, and is only accessable from landing pads that can be raised and lowered from the ocean, making it so that only ships that are wanted can dock.
