Asheya was the queen of Eros. She had absolute power over her people. According to the law, no Erosan could have children until the queen consummated her marriage. However, whenever a marriage was arranged for Asheya, her intended mate tragically met his death.
When the Eighth Doctor and Samantha Jones landed on Eros, Asheya was attracted to the Doctor immediately. She wanted him to be her consort, against the wishes and advice of her vizier, Zoleon. When Zoleon challenged the Doctor to a duel to the death for Asheya's hand, the Doctor promised Asheya he would stay if he won. However, Asheya realised that he did not want to stay, and let him and Sam leave the planet. (PROSE: The Queen of Eros)
