Astroarchs are Vessels who were once deemed worthy of becoming hosts for Persona's. However, due to the power that they inherited, they became lustful for more power to the point that they consumed their Persona and in doing so have become mindless wanderers of the Dimensional Void searching for ways to harvest more power. Most Astroarchs remain in the Plains of the Abyss, which is the inbetween realm for the dimensions. If an Astroarch manages to escape the plains and reach a Dimensional Gateway, then the Agents of Exiled are dispatched to eliminate the threat. Although, Astroarchs are considered to be mindless, without any conscience, they are still extremely powerful and even more so since their limit breakers have been removed and can use their full power without restraint.
