A meteor landed and brought a disease with it. Those infected transform into monstrous beings called Phantasms. The company Astral Tech built both a defensive barrier and the devices — called Apostoloids — that power it, using the meteor as raw material. Inside the protected city of Faeble, only those deemed salvageable are allowed to live. The rest are expelled into the outside world. The outcasts survive in hidden settlements underground, always within reach of the Phantasms. Two heroes living outside the city's walls begin to uncover a scheme running beneath all of it, and find that the life of comfort inside Faeble is not the whole story.
