The Lord of Karhold is a title in the world of Game of Thrones. The title was held by Rickard Karstark until he was beheaded by King in the North Robb Stark under charges of treason. Harald Karstark ascended to lordship afterwards. The holder rules the castle Karhold and its surrounding lands, a heavily forested area overlooking the Shivering Sea. The title is traditionally held by a member of House Karstark. Karhold lies in the North, and it's holder therefore swears fealty to the Warden of the North, whoever they may be.
