|One of the four High Houses of Ishgard, House Durendaire is arguably the greatest  as of the 5th year of the Seventh Umbral Era, with none flusher with coin and manpower.  Among their responsibilities are the protection of the Whitebrim Front  and the Observatorium , where Forlemort, brother to the Count de Durendaire, serves as its chief astrologian.  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. 
On the Ishgardian flag, House Durendaire is represented by the Bell, the very same seen at Whitebrim.
