Rokk the Walking Mountain is the twenty-seventh book in the series. Rokk is a gigantic, monolithic Beast, essentially a mountain brought to life by dark magic. Rokk's strength is its size and immense crushing weight, making it an almost immovable object. Tom's quest involves scaling or infiltrating the Beast itself, as attacking the exterior is ineffective. He must find the Beast's core or a magical weakness hidden within its rocky structure. This quest is a test of endurance, climbing ability, and the courage to approach a monster that can destroy Tom with a single step.
