Arathena Throckrod was the daughter of Zilbo II, king of Quendor. She married Harmonious Fzort before her father's death in 451 GUE. Although Zilbo's younger brother Bozbo was still alive and more than willing to take the throne, matters were complicated by the existence of Arathena. No woman had ever ascended to the throne of Quendor, Zilbo himself had made no clear plans for who was to succeed him, and the princess herself had married into the Fzort clan. Because of this, Harmonious Fzort, himself nothing more than a one-time royal advisor and grandson of Gladius Fzort, proceeded to claim the throne for himself on behalf of his young bride, Arathena.
