West of Drentae is the Barrier Ocean serving as a “barrier” between Drentae and the Monster Continent. At its southern edge, the Barrier Ocean meets the Boiling Sea. Various map makers differ on the boundary, but as the choppy waters of the Barrier calm in the Boiling Sea’s undercurrents, most sailors can identify the change. The northern border is the Frozen Sea. This boundary changes with the ice flows. While ice bergs do float in the Barrier Ocean, the ice cap itself is the Frozen Sea.
