The three Bowls. The water pours off the uppermost bowl in constant waterfalls, and continues over the Rim down to the lowest Bowl. Where the water crashes down into each bowl, that line creates the divide between the Shallows and the Deeps.
The Bowls are rumored to be supported in the center by a huge column, but no one really knows how they are held up, or if they simply float on air.
You live in the Center Bowl, on the Western Rim.
