The Outer Ocean (Taragat: Men doet) is the vast ocean that dominates the surface of Menem, fully covering the "back" hemisphere, and surrounding the three large inhabited continents of Tevra, Jirenes, and Ijeida. It is connected to the Inner Ocean, also called the Circle Sea, by the wide seas that separate the landmasses. The Outer Ocean was little explored and poorly understood until late in the modern period, when explorers began venturing into its waters. Before then it was regarded by many with suspicion as the "great unknown", as distant and unattainable as the stars above.
