The Wheel of Time - The Call of the Horn
Lake Somal is the largest lake in the Westlands. It lies between Paerish Swar and the Mountains of Mist, south-east of Arad Doman and east of Almoth Plain. Despite its size it is somewhat remote and relatively unknown, although a trading road links it to the city of Katar a hundred miles or so to the north-west. Some maps show the lake as being the source of one of the many tributaries of the River Andahar.
The Dragonsworn used the area as a base of operations during their war against Arad Doman. They were defeated in a battle on the lakeshore by General Rodel Ituralde, but orders from King Alsalam Saeed Almadar meant that the victory could not be completed.
