Your city is on its knees, almost fallen from an unknown plague that causes people to turn into flesh-hungry monsters. There are few survivors, scattered here and there are houses in which the locals have barricaded themselves, not wanting to even think about sticking their noses outside until the plague miraculously ends. Two communes have survived: Silk Brush, who believes that salvation from the plague lies in opium and the Church of the Holy Blood, whose faith in the healing power of blood is strong and based on ancient city traditions. The little that you need to know as you run, and monsters chase you, so you'll have to knock on the first door that comes your way... And see what comes of it.
