Whakarun

A cliff ascent out of the sea that is split in half leaving the center between sunside and darkside by the sea. Boats enter the center and are then lifted using a crane aqueduct system before being introduced to the Above cliffs rivers to continue their journey. Though the surface only shows a thing crack in the land, there is a vast spherical cavern of dark water underneath the surface. The people have business dredging for things below in order to avoid the wrath of the leviathans below.
