In the world of Hilya, some children are able to create their “Imago” – a magical animal - out of imagination. Our story begins with four children who have accidentally awoken an ancient evil. And now, as inexperienced as they may be, the only way they can make up for it is to embark on a fantastic journey throughout the whole realm to meet and gather the fabled Primagos, the most powerful imagos on Hilya.
