Cerulean Basin

An island floating high above the far side of Quill 's largest island, the Azure Sea, the Cerulean Basin's surface area is given over to an ancient caldera filled with what was once a large inland sea. One of the walls of the caldera was broken during the Fall, and now an unimaginably huge waterfall, the Barrier Falls , streams out of the sky in a vast curtain, blocking out the sky and horizon, cleaving the land of the Azure Sea into two separate environments.
