Despite being one of the High Houses, House Haillenarte has fallen considerably behind the other three in terms of influence and respect due to the loss of both the Stone and Steel Vigils, which were under their care, as well as suspicions of heresy and collusion for allowing the fortresses to fall to the Dravanians. Nevertheless, they remain the steadfast friends of House Fortemps. The house is responsible for the protection of Skyfire Locks and the Monument Tower, as well as the oversight of the Skysteel Manufactory, which produces ballistae, cannons, and, more recently, magitek-inspired creations based on technical innovations by the Garlond Ironworks. The house is also responsible for the protection and development of Camp Cloudtop, though even those stationed there admit that it is busywork for those unsuited for more dangerous tasks.
Following the end of the Dragonsong War, House Haillenarte led Ishgard's people into the restoration of The Firmament, a bastion of residential housing and a bustling marketplace. While all houses participated in the reconstruction, the work of Francel de Haillenarte and his connections with those both in and out of Ishgard (particularly the Warrior of Light) allowed for the project to flourish the way it did.
In the Ishgardian flag, the House Haillenarte is represented by a rose.
