Storm petrels

1453. Dark times have come to Europe: Constantinople has fallen, the Ottoman Empire is conquering new lands, and the Pope is worried about his flock... and his power. His Holiness issues an order to the Order of Darkness, whose members are tasked with seeking signs of the impending end of the world everywhere and creating a "map of human fears." And onto the stage steps Luca - a clever young man beyond his years, who is sent on an expedition with the monk Brother Pietro and the servant Freyze. By fate, they are joined by the beautiful maidens: the noble Isolde and her companion - the Moorish Ishrak. They encounter the prophet John the Good, gathering children for a new crusade, but then something unbelievable happens.
