Ferrous Cranus is utterly impervious to reason, persuasion and new ideas, and when engaged in battle he will not yield an inch in his position regardless of its hopelessness. Though his thrusts are decisively repulsed, his arguments crushed in every detail and his defenses demolished beyond repair he will remount the same attack again and again with only the slightest variation in tactics. Sometimes out of pure frustration Philosopher will try to explain to him the failed logistics of his situation, or Therapist will attempt to penetrate the psychological origins of his obduracy, but, ever unfathomable, Ferrous Cranus cannot be moved.
