Wolverine must overcome his feelings for Jean, and Storm must overcome her crippling claustrophobia, when the team journeys into the sewer to rescue Jean Grey & Cyclops from a race of hideously deformed mutants known as Morlocks, and their leader Callisto, who wants to make Scott her king.

Haunted by visions of a strange woman, Rogue must come to grips with the dark secrets of her past prior to joining the X-Men.

Mutant-draining, pterodactyl-man Sauron is persuaded into capturing Storm by Zaladane, the high priestess of Savage Land Sun God Garokk, unaware of her ulterior motives for unleashing the mutant's full potential.

Storm's unfettered weather-fury continues setting the stage for the rise of Garokk. Even if Storm can be brought back under control, the Sun God's geothermal rejuvenation will spell an end to the Antarctic paradise known as the Savage Land.
