The Divenhal Sea (Diven from Elven for Divide, Hal from Old Castanorian for Land) is the sea bordered by Cannor and the Dameshead on the north, and Sarhal on the south. It is a warm and mostly inland sea, divided into the Western Divenhal, and the Eastern Divenhal. The average depth of the sea is around 2 kilometers, compared to the 3.5 kilometer depth of Uelos' Lamet Ocean, and the 1 kilometer depth of the Ruined Sea. It is colder than the Ruined Sea, but warmer than Uelos' Lament.
It divided into two halves- West Divenhal, and East Divenhal. East Divenhal is the elder, warmer, and shallower of the two, its shores containing Kheterata and Bulwar. It was in this sea where humans first plied the waves, and one of the safest, at least, weather-wise, in the world. It is so calm in the eastern portions of the sea that looking into the water is like looking into a mirror. The Dwarven hold of Ovdal Tûngr is famous for this, as ships in the harbor will see a reflection of the hold's massive carved windows and edifices in the water below. The northern parts of the East Divenhal along the coast of Dostanor, is usually referred to by the name Sea of Follies. The Mother's Sorrow delta, the Suren, and the Dostanesck all empty into the sea. The two halves are separated by the Isle of Tef.
West Divenhal is the colder (but still warm), stormier, and deeper twin of East Divenhal, having more in common with Uelos' Lament Ocean than its twin. The seas are inhabited by the Dog Corsairs, who raid the coasts of Sarhal and Cannor for captives to work on their farms and in their mines. The southern coasts of this sea, Akan, were first settled by the Kheteratans, during the Age of Awakening. These colonies were destroyed by The Onslaught, but were refounded, and still exist, to this day. The northern coasts of western Cannor are warmer than the rest of Cannor, due to the sea. It is separated from the Dameshead by the Damesear.
