Southwest of the Colovian Highlands, the Brena River and the mountains of the Colovian Highlands form the northwest border of Cyrodiil. On the other side of the river is the province of Hammerfell. A shipwreck is located at the mouth of the river. The Hero cannot enter the wrecked ship. However, beside it on the large stone is a chest containing minor loot. There are also multiple Mudcrabs and nirnroots within in the area.
