Visiting an old cliff-top castle that was home to knights during medieval times sounds like an exciting adventure in itself, right?

But when Jack, Emma and Albert learn that a treasured relic has been missing for hundreds of years, the crew decide to search for it. Unscrambling the cryptic clues left around the castle, they come across secret passages, run into plenty of dead-ends, and even find themselves in the deep, dark dungeon! As they uncover the castle's exciting history and hear of the brave knights who once guarded the kingdom, will it bring them closer to discovering the Sword of Dragon's Fire? Or is the story of Sir Xavier and his noble knights just a made-up tale?
