House Dragen of Holthall was founded thousands of years ago, and was descended from the main branch of House Dragen. The ruled over the castle of Holthall.
At the end of the Dragen Rebellion, this house was exiled, and Holthall was given to Berr, a wildling Thenn who had traveled around the wall and made it into the north. His line would eventually become the members of House Berrow. The Dragens of this house were all killed by several minor noble houses in the North, hoping to get recognition for their "services".
