Warsaw at the beginning of the 20th century. An enclave that has appeared in the city, inhabited by demons from dark legends, is surrounded by a wall of silver rods. The houses there have acquired unusual properties, and the streets change directions. Similar formations arose in Moscow and St. Petersburg. Only royal patrols and licensed alchemists can enter inside in search of ingredients for experimental potions. Polish alchemist Olaf Rudnicki, together with an officer of the royal guard, faces mortal danger. Meanwhile, war is approaching. Magic duels, experimental drugs and growing tension at the site of the other world's breakthrough lead to an ending no one expected.
