Queen Luna is Nebula's late mother, who ruled the Wisp Kingdom alongside her husband, King Sol. She was an extrordianry spellcaster, as she and her husband were the only two capable of wielding the complex spell that would seal Nova within their daughter. However, upon completion of the spell, she and King Sol were devoured by Nova, and are now presumed dead. Her coloration is blue.
Luna was once a simple wisp named Nani Iofiel, who changed her name to Luna once she was wed to King Sol. Nani Iofiel became one of the famed Seven Heroes of Empyrea, who worked alongside others such as Lilith Haniel to defeat Abbadon.
