From the back of the book:
The Darkness is dominated by the Light. The Dark Lord is defeated; his armies scatter under the onslaught of steel legions of the Light. Entire tribes and peoples are under the threat of annihilation. In these times of the all-burning Light forces of the Darkness need their own ... heroes.
Back Stabbers is the role-playing game about the band of typical enemies of fantasy adventurers; about the group of monsters and villains doing bad things in the realm of the victorious Light. Players take roles of those dark creatures while the Master describes the world of fantasy where the Light won – and it is more severe than the Darkness. By talking and throwing dices participants of the game create the whole new story.
