Eostra Nihiltian is the dark leader of the Shadowy Ones and the leader of the Corpse Empire. Originally an Elemental Prince of the Annihilation Kingdom, Eostra, power-hungry and darkly talented, masterminded the deadly Great Being Wars, that resulted in massive losses of life and the destruction of three planets. She later seized power in the Rebublic of Xaterex, becoming leader, and eventually took control of the Rebublic by force and turning it into the Corpse Empire, unknowingly being manipulated by Nihiltidax. She and her elite servants, the Shadowy Ones, then began a century-long campaign of destruction across the Solis Magna System, eventually taking control of most of the known universe.
