- "A haunted ship, a doomed man, and a voyage of no return... Rear Admiral Luther Catalus, once a famous naval strategist, had been implicated in a failed rebellion. Rather than executing and making him a martyr, TOG chose to reassign him to the INS Kraken, an ancient, and some same, haunted battleship, and send him on a suicide mission deep into enemy territory! This scenario pack includes personality profiles, history of the INS Kraken, and fifteen Leviathan scenarios between Admiral Catalus's battle group and the overwhelming adversaries he faces in Shannedam County."
