Her parents died when she was in her childhood, and at a young age Lurline and Rhiannon take their parents' roles as rulers of Elphame and bringers of the day and night. The two would end the Snow Queen's reign of terror over the Land of Stories, and traps the Snow Queen in a urn.

Every morning, Lurline would raise the sun, and every evening, and Rhiannon would raise the moon. Together, they kept the balance perfectly. However, as time went on, Rhiannon grew jealous: the mortals would be awake to enjoy the day and love, admire, and appreciate Lurline's work, but would always "shun" Rhiannon's night by sleeping through it.

At that moment, the bitterness in Rhiannon's heart manifested and consumed her, transforming her into Maleficent, the incarnation of pure evil. She rebelled against her sister and led a rebellion against her.
