Western Ocean
From DQWiki
The Western Ocean is the body of water bounded by Terranova in the west and the main Alusian continent in the east. It is not sure what bounds north and south but ice is the most likely suspect.
Some mariners split in two. The Northern Ocean is what lies north of the equator, while that south is known as the Southern Ocean.
The sahuagin came from the Northern Ocean when Leviathan rose, displacing them and forcing them south. Not much else is known of what lies there.
The Southern Ocean contains and surrounds both Pasifika and Zeyland
