One of the X-Men's oldest, deadliest foes, the energy - stealing creature known as Sauron, has returned to menace the Savage Land - the prehistoric jungle hidden in the Antartic. At the behest of their old ally Ka-Zar, the Savage Land's protector, Wolverine, Storm, the Beast, Iceman, Psylocke, Cannonball, and Archangel have come to help stop Sauron's latest reign of terror. But this is not the same Sauron the X-Men have defeated in the past. Gone is the overconfident, boasting monster, and in his place is a cunning, careful, deadly foe who may be too much for even the X-Men to handle!
