Kul Tiras is not a "Kingdom" in the proper sense, in that Kul Tiras does not have a King or a Queen. Instead, power is split amongst the major houses - each controlling a region of Kul Tiras, and an aspect of Kul Tiran society. The Lord Admiral of Kul Tiras is the Head of State, wielding executive power and commanding the armed forces - with the support of the other major houses.
Kul Tiras is divided into three regions - each ruled by one of the Noble Houses
House Proudmooreis the ruling house of Kul Tiras, with it's seat ofpower at Proudmoore Keep in the capital of Boralus in Tiragarde Sound. Through the Proudmoore Admiralty, House Proudmoore commands the Kul Tiran Navy and Marines - providing for the safety and defense of Kul Tiras. Lady Katheirne Proudmoore, who had ruled as Lord Admiral since the death of Daelin Proudmoore at the end of the Third War, has recently adbicated the position of Lord Admiral of Kul Tiras to her daughter Jaina Proudmoore after she rescued the Kul Tiran fleet and returned them back home. Jaina's intervention came just in time to thwart the coup attempt by Lady Ashvane, forcing her surrender and thus ending the Siege of Boralus. Lady Jaina Proudmoore rising to the position of Lord Admiral has proven to be a challenge for some Kul Tirans who still blame her for the deaths of so many at Theramore years ago, and accepting her as ruler after having spent years despising the so-called "Daughter of the Sea" is difficult. In these uncertain times and with Kul Tiras having just rejoined the Alliance as we come under attack by the Horde, we look to House Proudmoore and to Lady Jaina to help us weather this storm and see the Horde pay for their aggression.
House Stormsongcontrols Stormsong Valley to the north, where many of the best farmlands and shipyards are. Stormsong Valley is also at the center of the Kul Tiran religion of Tideworship, which pays reverence to the Sea and is the main religion in Kul Tiras. Lord Stormsong was recently corrupted by the forces of Lady Azshara, and had to be deposed and killed by Kul Tiran and Alliance forces. His nephew Brannon Stormsong is now the only living heir to House Stormsong, but is not yet ready to rule over the region due to his inexperience. The Storm's Wake, the sect of Tidesages who escaped Lady Azshara's corruption and remained loyal to Kul Tiras, rule in his stead and advise the young Lord as he grows into this new role and learns the heavy weight of it's many responsibilities.
House Waycrestcontrols the Drustvar to the west, a mountainous region rich in ores and minerals, and with expansive forest lands which supply much of the lumber used in the construction of Kul Tiras' legendary fleets. Lord and Lady Waycrest were also recently deposed by their daughter Lucille Waycrest with the help of Kul Tiran forces, the Alliance and the newly reformed Order of Embers. The two rulers of House Waycrest were corrupted by the vile magics of the Drust King Gorak Tul, and sought to bring all of Kul Tiras under the power of the Drust. Drustvar is also unique in Kul Tiras, in that there is a significant portion of the population who follow the Holy Light rather than Tideworship, and practice many mainlander traditions such as worshipping The Light at Chapels as places of worship rather than the Tide Shrines, and burying their dead in the ground rather than committing their bodies and spirits to the sea. Many of Kul Tiras' greatest warriors also hail from Drustvar.
House Ashvane, now defunct, shared control of Tiragarde Sound with HouseProudmoore, and controlled commerce and the merchant marine of Kul Tiras. Lady Ashvane was the mastermind of a plot to overthrow House Proudmoore and take control of Kul Tiras by allying herself with the Irontide Raiders - providing them with Azerite weapons and ammunition which the pirates used to destroy Daelin's Gate and lay siege to the capital city of Boralus. All assets of House Ashvane have been seized by the House Proudmoore, though many fugitives who conspired with Lady Ashvane remain at large.
