Relevant WotLK Update: WotLK Tuskarr: Humanoid Walrus People New WotLK Model: Tuskarr
The environments section of the World of Warcraft: Wrath of the Lich King website has been updated with new information about the vast arctic wasteland of the Dragonblight, one of the many new regions you will be able to explore in the upcoming expansion. The update also includes a fly-through movie, new concept art, and new zone screenshots.
Here dense forests surround a vast arctic wasteland littered with the massive, gleaming bones of perished dragons. In the center of this frozen expanse lies Wyrmrest Keep, a structure believed to be built by the world-shaping titans shortly after Azeroth's creation. Many legends hold that the five great Dragon Aspects were blessed within this fortress and given their charge to watch over the budding world. Perhaps it is for this reason that dragons nearing the end of their lives come to the Dragonblight to enrich the land with their passing.
