Au Set is a cosmic being created by the entity known on Earth as Set or Seth from ancient Egyptian mythology.
About 3000 years ago, Horus defeated Set and imprisoned him within the heart of a back hole. Horus then cursed the prison so no being with malicious intent could ever escape. In time, Set created a new being from his own essence. He then taught this new being "of Set" or "Au Set" to defend the innocent and punish the wicked while weaving an intricate tale of lies that painted Horus as a force of chaos and evil.
When Au Set was prepared, it was released upon Earth and took the form of a human female. After driving several Skull gang members to the brink of madness with her powers, Paragon City authorities were perplexed by the her inability to provide even the most basic biographical information. Eventually Au Set was placed with the Paragon Super Juniors Academy.
Under the schools tutelage, Au Set developed into a staunch protector of the innocent until her encounter with Horus. Still in the thrall of Set's lies, Au Set attempted to destroy Horus until realizing the truth. Crushed by her Father's betrayal, Au Set turned on Set and nearly defeated him until he retreated to a reality of his own design.
Au Set now spends most of her time guarding the portal created by Set to insure he cannot return.
Powers and Abilities
Created by Set from his own essence, Au Set can manipulate cosmic energies for offensive and defensive purposes. Au Set also displays powerful mental abilities allowing her to influence and, in some cases, control human beings. Due to her nature, Au Set cannot maintain physical contact with mortals for more than a few moments without draining their life energy. Extended physical contact results in madness and eventually death.
Well aware of the effects of her powers on mortals, Au Set is generally reserved and quiet even to individuals with which she is well acquainted. Since the defeat of Set and subsequent graduation from PJSA, Au Set has focused mainly of the dimensional rift and has become very distant to virtually everyone except the demon girl Alawa (AKA: Better off Deadly).
