Law of the Jungle (X-Men)

The energy stealing creature known as Sauron has returned to menace the Savage Land--the prehistoric jungle in the Antarctic. At the behest of the Savage Land's protector, the X-Men 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. He is now a cunning and deadly foe who may be too much for even the X-Men to handle! .
