Encircling Ocean

The Encircling Ocean (also called the Great Ocean, the Outer Ocean, or the World Ocean) is the enormous, world-girdling ocean that covers a majority of Urva's surface. It surrounds the continental landmasses of Umre and Achuirea, which in turn surround the Inner Oceans. 
The Encircling Ocean is connected to the Inner Oceans in only three places: The narrow strait called the Gates of Barossus between western Vhaluzia and Ulthark's southeastern tip, the wider Myrrenian Channel between eastern Vhaluzia and southwestern Achuirea, and the very wide Durrak's Passage between northern Achuirea and the Cape of Woe at the end of Thelbiron's Forvirad peninsula.
