House Oakheart of Old Oak

Casa Oakheart de Roble Viejo

House Oakheart of Old Oak is a noble house of the Reach, sworn to House Tyrell and seated at Old Oak. It is one of the oldest lines in the region, its origin traced by legend back to the age of the First Men.

Its members turn up at some of the earliest turning points in the history of the Seven Kingdoms, from the war that ended the green kingdoms to the blood disputes that later split House Targaryen.
