The Soul-Eaters of Corpse were created after Eostra discovered how to create Corpsians with her own special powers. First she created the Soul Seekers, with their ability to track souls, then the Soul Guardians, with the extra ability to weaken souls, Soul Renders, with the extra ability to dominate and possess souls (Including the souls of living beings). Finally, she created the most powerful Soul Corpsians, Soul Eliminators (and the most powerful overall Corpsians), who contained so much of her power they were nicknamed the "Children of Eostra". They possessed the extra abilities to rip souls from a living body and devour them-Eostra's most powerful abilities. Eostra, seeing how powerful they were, used them to be the ultimate destroyers, and plotted to loose them on her enemies in her deadly plan for dark revenge.
War of XaterexEdit
During the Xaterex War, Eostra used the Soul Eaters' power to augment her own when she annihilated Xaterex. Before then, she would send prisoners that she could not kill (or prisoners that she wanted to torture.) to the Twilight Void. Many of the warriors who were captured during the Xaterex War are still rotting there, wondering weather the long war is finally over. After the destruction of Xaterex, Eostra charged them with guarding the Void for all eternity. There they remained for nigh on a millenium, guarding their prisoners.
The Soul Eaters have a ridged heirchy, with the Soul Eliminators dominating every aspect of Soul Corpse life. However, their minions do their work for them. As the soul corpsians are virtually souless, they do not resent the control of the Eliminators.
