The world, tormented by demons and evil, is also forced to face the plague. A terrible disease forces people to leave their homes and flee away from plague-affected areas. Fortress-monasteries were considered one of the safest places. Created by the Order of Dogmas, these citadels were impenetrable shields of humanity on the path of demons. In the battles with evil spirits, the Dogmas were actively helped by the “Liquidators” detachments from the Order of the “Royal Scouts”, but both orders were powerless against the spread of the plague. The Twelfth Reaper and his arbiter, a young girl magician, must find a way to stop the plague. But they had no idea that the plague was only the beginning of their troubles.
