Dwynnen was a barony on the southern coast of High Rock, in the Iliac Bay. It existed in the late First Era, as well as in the late Third Era. It shared borders with Anticlere and Urvaius in the south, Phrygias to the west and north, Bhoriane and Kambria to the east, and the Wrothgarian Mountains to the north. Its capital was the city of Dwynnen. According to legend, the province was created shortly after the man who would become the first Baron Othrok emerged from the wilderness and defeated the lich of Castle Wightmoor and its undead force. The Battle of Wightmoor is believed to have taken place in in 3E 253, and is celebrated by the people of the barony every 5th of Suns Dawn.
