Through Kevin, the Forever Knights ask Ben for help. They've been the secret guardians of an imprisoned dragon for a thousand years, which has only now escaped. With Ben's help, they'd like to finally kill it, but in helping the Knights, Ben discovers that the dragon is an alien capable of speech. Able to replace its broken translator, Ben turns moderator to keep the embittered, vengeance-minded dragon from making a blood-bath of the Knights, while Gwen and Kevin deal likewise with the Knights.
