Lyon - the world of eternal night, where the highest demons live, in all obedience to their Lord. He longs to gain power over the wizards, but the Queen of the World has so far managed to restrain him. My name is Sheriad, and I hate the Lord, because he kills everyone I love. Magicians capable of subduing demons are extremely rare. Therefore, when I came across young Alvin, who has a special gift, I knew that he would change the balance of power in our favor. Alas, the demonologist was not trained. I sent him to the Arliss Academy, but could not hide him from the Lord, and he is trying to blackmail the young man into service. Now the world between wizards and demons depends on the choice of a boy whose magical potential is growing day by day, and who does not even understand that he has become a pawn in a big game.
