Wrath of the Lich King Environments Update

Blizzard's official World of Warcraft: Wrath of the Lich King website has been updated with information about "the lush, primordial mountains of the Grizzly Hills."
In the heart of this wild frontier lies the ancestral home of the furbolgs, Grizzlemaw. For generations the tribal furbolgs have worshipped a colossal prehistoric bear that roams the surrounding wilderness.

Although the gentle furbolgs have grown accustomed to living in relative peace, recent incursions have forced the ancient tribes to engage in battle. Trappers are encroaching upon furbolg hunting grounds, and the goblin Venture Company has begun large-scale deforesting operations throughout the region.

Despite the trappers and goblins, the most imminent threat comes from the north, where throngs of undead Drakkari ice trolls have begun pouring from their stronghold of Drak'Tharon Keep.
