1453 Dark times have come in Europe: Constantinople is captured, the Ottoman Empire is conquering new lands, and the Pope is worried about his flock... and power. His Holiness gives orders to the Order of Darkness, whose members are called upon to look everywhere for signs of the approaching end of the world and create a “map of human fears.” And Luca comes to the fore - a young man smart beyond his years, who is equipped for an expedition together with the monk Brother Pietro and the servant Freise. By the will of fate, beautiful maidens will join them: the noble Isolde and her companion, the Moorish Ishrak. They encounter the prophet Johann the Good, who is gathering children for a new crusade, but suddenly something incredible happens.
