A LEGENDARY ANCIENT TOWER WITH A DARK SECRET Lost throughout the ages—until now. On their way to Mentorship, Sam, Emma, Lillia, and Gus stumble upon a device that gives them a clue as to the whereabouts of the mysterious tower, and its purpose. Now that the Darkness has risen once again, so much is at stake, including the future of Lior. The dark forces are growing bolder, and there is increasing concern of another attack. But that is not the worst of their worries....there are rumors that the Dark One has broken free of his bonds. The last time he roamed free, nearly all of Creation and Lior lay in ruins, and the Followers of Light paid a heavy price in order to stop him. Now, as the rift between the Descendants and Watchers remains, the regions of Lior do not have the power to challenge the Dark One, who plans to destroy all who oppose him. Once again, Sam and his friends find themselves responsible for the plight of Lior, but not before realizing the potential power the Darkness has on each of them. Follow Sam, Emma, Lillia and Gus as they unearth the secrets held by the Watcher Tower.
