Since the beginning, the angels have always been there, protecting us and keeping balance in the world. They have always guarded the earth by protecting the veil, the boundary that separates the reality of the living from the realms of the afterlife. It is a sacred duty they will do anything to uphold, even live in secret among us. In a future controlled by the oppressive hierarchy and constantly being infiltrated by supernatural forces from beyond, a group of angels work to preserve balance in a world where the helpless and weak pray for a miracle. It is an era of trial for all beings, the era of a purgatory dynasty.
