House Durendaire is currently the greatest of the High Houses. They are responsible for protecting the Whitebrim Front and the Observatorium. Known for its military might and superior dragoons, House Durendaire was tasked with defending the Dusk Vigil until its destruction in the Calamity, as well as reclaiming the Stone Vigil when it was lost by House Haillenarte shortly after. In addition to these responsibilities, the house has also joined with their staunch allies, House Dzemael, to secure and rebuild the Falcon's Nest.
In the Ishgardian flag, the House Durendaire is represented by the bell, the same seen in Whitebrim.
