Nefertari is female and therefore describes part of the circuitry of the cosmos, she helps provide the nourishment of negative charge to an Electric Star. She is shown supporting the Vulture described by Nekhbet and then a Star on her head, describing how negative charge is 'scavenged' from deep space or the Aether by a process involving induction.
