House Hightower is an old and proud house and the Lords of Oldtown. Currently, they are led by Lord Leyton Hightower. They along with their Tyrell overlords have aligned themselves through marriage with the usurper, Renly Baratheon. Besides being as rich as any house in the seven kingdoms, the daughter of Lord Hightower is married to his liege Mace Tyrell and his granddaughter is now married to Lord Renly Baratheon. House Hightower will not be moved with these marriage alliances in place.
