For millennia the Great Dragonblight has served as the enduring heart of Northrend. 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.

Surrounding Wyrmrest Keep are five majestic dragon shrines: red, bronze, green, blue, and black, each blessed with the powers of its respective flight. In recent times the undead Scourge has laid siege to these shrines in an effort to further its attempts at raising terrifying new variations of undead dragons to serve the Lich King.

In an attempt to arrest these invasions, the red Dragon Aspect, Alexstrasza, has begun recruiting heroes to aid in the fight against the Scourge, even as the taunka and tuskarr wage their own desperate battles against the undead. The one-time Scarlet Crusade, now the Scarlet Onslaught, has arrived as well in the hopes of claiming victory in their ongoing campaign against the Lich King and his minions.
