The Queen of Andor is the ruler of all of Andor. After a Queen dies or is deposed a person who wants the throne must get approval by the majority of the noble houses of Andor. There have been many Succession Wars. The queens (since Ishara) have sent Daughter-Heirs of Andor to the White Tower to seek training and guidance before becoming queen. Also, the queen's eldest son would also be sent to the White Tower to gain military training before claiming the post of First Prince of the Sword. There have never been Kings of Andor, and Queens of Andor are full queens regnant.
