Lethe

AKA-
 * The Djinn
 * Entity of Mist
 * Carrier of River Lethe
 * Betrayed Soul-Wielder
 * The Damned Martyr of Altum of Paradisum
 * Formerly, Iustitia Misericordiae

Lethe is a product of spiritual rape from the Grudgi (Male Demon of Envy) Duke Dantallion of Lull (which was often mistaken by the Zorastrians as "Aka Manah") using Dean's Seed. She is the purpose of one of 4 Sacrifices for the 5th seal because, only from "the Soul of a Djinn" could the 25% of the seal be broken. Grace re-named Iustitia Misericordiae the Soul-Wielder as Lethe, from the River of Forgetfullness, Lethe.
