Last Hearth

The Last Hearth is a castle in the North and the seat of House Umber, a vassal house holding fealty to House Stark of Winterfell. It is located south of the Gift, east of the Kingsroad and north of the Last River, and the nearest castle to the Wall. Because of this, Last Hearth has experienced more Wilding attacks than any other Northern castle.
