Place of action is Rubież, the last region of the world suitable for life. Outside lies the war-devastated land, surrounded by darkness, or under distribution power through the ancient weapons. On the ruins of the distant splendor of the few born in the new civilization, a new community. The most fertile lands lie within the limits of totalitarian Dominatu Ebionitów.
Extermination of the known world has not produced the technology, climate change or disease, but the Ebionites, a sect of powerful occultists allied with ghosts. Today, the Emperor speaks to almost all the survivors of the world. The idea of freedom, solidarity and resistance against the common threat brings union of the Free Families, which will be the heroes of the story.
In addition to compartments in the dark forests and barren wastelands lurk the defile: followers of the condemned cults, crazies, and anathema. Rubież is a wild and unbroken land, in which traverse the ghosts, beasts and men.
