The Snow Queen

Storyline: A mysterious presence has threatened humanity for hundreds of years as it lurks in the frozen wastes people avoid. Nearly unnoticed as its power grows, she's been slowly draining the planet of one of its most precious resources. It takes two groups of adventurers, separated in time, to defeat her and the army of demons and monsters she can summon- one with swords and shields, the other with assault rifles and body armor.
