Lagon, a parallel world where you will find yourself!.

Johnny Pull is a fatherless Scottish teenager who loves comics and tales. He goes on an excursion with his classmates to an emblematic castle in Scotland. There he finds the grave of Sir Light, the protagonist of a legend his grandfather once told him about. Johnny has a fascinating vision in front of the grave that will change his life forever.

Along with his two best friends, Michael and Vicky, he finds a very special and strange book, the Scottish Legends, an invisible book that holds the key (the prophecy and the rite of passage) to fulfill the feat that Sir Light did not finish. Eventually, Johnny and his two friends enter the land of Lagon, a diabolical parallel world where the spirit of the dead knight, trapped between two different universes, still wanders trying to finish the task he was unable to complete: defeating the unmentionable one. They may well succeed... anything can be possible.
