WoW: The Burning Crusade Caverns of Time Preview

Blizzard's official World of Warcaft: The Burning Crusade website has been updated with a preview of the Caverns of Time, one of the new dungeons that will be available in the expansion pack.
Deep within the Caverns of Time, the brooding dragon Nozdormu has awakened.

Since the world was young, the bronze dragonflight has safeguarded the winding labyrinth, monitoring the shifting timeways to ensure that the delicate balance of time is upheld.

But now the ancient Dragon Aspect Nozdormu has been roused by an elusive threat to his beloved caverns: dark, sinister agents have infiltrated the timeways, embarking on shadowy missions to alter the course of the past, present and future.

As a result, the bronze dragonflight has begun enlisting heroes to prevent the fabric of history from unraveling forever. For the first time, adventurers will enter the domain of the Timeless One, where they will undertake missions to prevent the sabotage of three key historical events.
