The Ellanora of Urantia | Francesca Albanese 

 53:7.1 The Lucifer rebellion was system wide. Thirty-seven seceding Planetary Princes swung their world administrations largely to the side of the archrebel. Only on Panoptia did the Planetary Prince fail to carry his people with him. On this world, under the guidance of the Melchizedeks, the people rallied to the support of Michael. Ellanora, a young woman of that mortal realm, grasped the leadership of the human races, and not a single soul on that strife-torn world enlisted under the Lucifer banner.
