With the help of his slave and local peasants, MAN-DAR reaches the underworld and rescues the barbarian. The High Priest follows MAN-DAR out of the underworld with an unearthly army, but MAN-DAR causes their demise. MAN-DAR escapes across the Forbidden Causeway to Atlantis with his slave, whom he promises to set free, and the barbarian he has fallen in love with.
