However, his small changes to reality here and there do not go unnoticed. To outsmart his pursuers, he decides to travel back in time and try his luck as a wizard in the Middle Ages. After all, what could possibly go wrong? As a hacking Yankee at King Arthur's court, Martin must now do everything he can to become a full-fledged master of his abilities, uncover the secret of the ancient wizard Merlin, and... well, you know, try not to get killed and all that.
