Kevin has arranged a meeting for Ben with the Forever Knights, who need help in slaying a dragon they have kept captive underneath their castle for 1,000 years. Slaying the dragon is the very reason their organization exists. After teaming up with the Knight’s mightiest warrior, Sir Connor, in a failed attempt to destroy the dragon, Ben notices that the dragon appears to be trying to communicate. Using Humungousaur to scare information out of one of the Knights, the team leaves the Knights behind and tracks the dragon to a warehouse where its spaceship is being held. Ben as Spidermonkey fits the dragon with a universal translator so it can speak, and it reveals that he is an alien mapmaker, but was captured by the Forever Knights. Angry after a millennium of imprisonment, the dragon arms itself to fight back. Ben convinces it to leave peacefully. Though the Knights believe to have lost their purpose, the news that a world full of dragons exists renews their pledge, as does their need to exact revenge on those who allowed it to return home.
