Erus is the prince of the Kingdom of Winds, who, along with his friends Rua, Alpi, and Sukre, with the help of the wizards, managed to pass through the four magical valleys and save the Good World. But their adventures did not stop there. Erus traveled to Isalo of the Unicorn Flights, where he discovered the existence of these magical and winged creatures, with which every child has a close connection. In addition, he learned there about the magic of words and how important kind words are in everyone's life.

The time has come for a new adventure, and the four friends are ready. The balance of the world is once again in danger, and Erus and his friends are traveling to the Invisible Worlds, where they make new friends, interact with creatures with strange appearances and customs, and must face new challenges. The intelligence, courage, friendship, and inventiveness of the four will be tested again. Will they be able to stop the Dream Hunters or calm the giant macaroni?
