At the border of the empire where magic and machinery coexist, the young dream weaver Ella accidentally gets involved in a conspiracy that could overturn the world. When she was hired by a mysterious noble and entered the dream of Marshal Ravengard, known as the "living myth", she discovered that not only ancient evil things were imprisoned deep in his consciousness, but also the real secret of the empire's rise and fall was hidden. In order to prevent the evil god from coming, Ella must join forces with the exiled magician, the declining nobles and other allies to uncover the dust-covered truth between reality and dreams, and make a choice before the end - whether to repair the crumbling old order or to build a new future on the ruins.
