Fallen angels came to earth seeking the most beautiful daughters of men, having children by them, the Nephilim. The fallen angels left, but their demonic sons remained, thirsting to conquer the Pre-Cataclysmic World so they could rule as gods. One of the most oppressive is Gog the Oracle, a pitiless monster. He has gathered his galleys and enforcers to crush the men who have risen up to resist him. He also seeks Cain, the deadliest swordsman in existence, the first murderer and ageless wanderer. Cain will be his hidden blade to strike at his enemies. Lod leads those who have thrown off their Nephilim shackles. He has vowed to break into Gog's swamp city and end the creature's reign of terror. Now the hour of retribution is at hand as Gog's enforcers sharpen their swords and as men train mammoths for the battlefield. Now the plans of demon and man clash head on, winner take all. Sword and sorcery, mind and muscle, galley and catapult, Armageddon comes to the Pre-Cataclysmic World in this, the eighth book of the Lost Civilizations Series.
