16 book in the series "Victor Glukhov." The hero Irridar Toh Rangor, Duke of Frontier, bites into the plans of the keeper of Sibyl, Rock, and changes the future of the entire planet. Imperceptibly and independently of him, the processes he began began to live their own lives. His friends and followers make their own decisions and destroy the designs of enemies. They quietly make many minor changes to Rock's plans. Rock himself does not see anything and does not want to see. He was dismissive of his sister Beota's information and fully confident of his victory. He waits for the opponent - a brazen upstart turned orc-keeper - to fall into the trap he has set.
