The Great Southern Sea is a body of water seen in a dream sequence in Blood Omen 2, it is likely that water seen in all parts of Meridian is connected to the Great Southern Sea. The Sea (the first body of water in the Legacy of Kain series not to be named as a "lake") is first seen to border much of Southern and Western Nosgoth in the opening video to Blood Omen 2 later Kain would travel along the edge of the sea to reach the Eternal Prison and even catch a ship from the Wharves to reach The Hylden City and Hylden Gate on an island chain across the sea[BO2].
