The Unicorn Queen is the leader of the unicorns of Luster. The throne is usually hereditary and the queen rules for her lifetime. So far, known queens include Arabella Skydancer and Amalia Flickerfoot. However, the leader of the unicorns can be male, because for a while Lightfoot was the heir to the throne. The next ruler is not determined by combat, as is the way of the centaurs.
