World-ocean

The world-ocean was an enormous body of water beneath the surface of the planet Utapau. The tidal forces of Utapau's moons created powerful currents that eroded the underside of the planet's crust and created many sinkholes and chasms. Combined with bad storms, this rendered the surface mostly uninhabitable, although the Amanin colonists are known to roam its plains.
