Among us live the Others, a select caste of followers of the forces of Light and Darkness, who derive magical power from human energy. Its use is regulated by the Agreement, controlled by the Inquisition. In accordance with it, every good must be balanced by evil. The forces of Darkness defend the right to unlimited freedom of human actions and the truth about the cruel reality, the forces of Light constantly consider whether their actions will provoke an escalation of undesirable consequences. In order not to deviate from the established order, they even issue licenses to vampires who suck human blood.

The Patrols of Light and Darkness carry out their mission through a refined combination of interventions and constellations that resemble battles between law and crime or intelligence raids. The indecisive results of their permanent confrontation then resemble the situation in the world with its unceasing conflicts and uncertainties, and the confusion of moral values. The attractive way of processing appeals especially to young audiences.
