No dog has ever been so loyal for so long to so stupid a master -- finally it pays off, and Groo''s dog Rufferto gets a little of the limelight. A bad run-in with the wizard Anakrony, Master of the Chronological Sciences, tests once and for all the bond between this barbarian and his best friend. Making another accidental stand against tyranny, Groo becomes separated from Rufferto, and an entire city is made to suffer.
