First seen as a mysterious glowing disk, she is known as the Queen of Arcadia. The queen comes in contact with Harlock's nemesis Mr. Zone long before the pirates ever encounter her. Knowing her only as a voice on the airwaves, Zone does not discover her true, non-corporeal nature until much later, when he realizes her potential as an ally against both Harlock and the Illumidas. She stops aiding him when she begins to suspect that he has lied to her about Harlock's true nature, and allows both Zone and Harlock to approach her homeworld in order to test their motives. She gives to both of them the Fire of St. Aqule, which Zone sees as a means to eradicate the Illumidas Occupation force (and he proceeds to do just that.) Harlock preserves his Fire to use for earth's restoration, and in doing so wins the favor of the Queen, who turns her power on the Illumidas homeworld, destroying it. To La Mime, the mysterious orb of gold light represents the Golden Goddess of Alozaran legend, an entity whose appearance signifies the end of all things. (Source: cornponeflicks)
