- "The Queen of Leonia, a sacred country. She used to be an ordinary village girl, but was chosen to become the Queen by the prophecy. Everyone is moved by the way she strives to fulfill her duty as Queen. Kiloph has been her close friend since childhood."
In accordance with the prophecy, Lyonesse was chosen by an oracle to become Leonia's queen. She is a very caring and thoughtful ruler who wants above all else for her people to be able to live in peace. She can be very timid and full of self-doubt, but Kiloph, Asmit, and Paternus provide her with much-needed support. If her country defeats the Esgares Empire, she earns the respect of Zemeckis when she tries to treat his wounds.
Lyonesse is a young woman with brown hair and large, light brown eyes. She wears a conservative white gown, a blue dress and miter, and a pale yellow shoulder cape. She carries a green orb that she can use to attack enemies with beams of light.
