The World of Warcraft: Cataclysm 4.3 dungeon, Caverns of Time: Hour of Twilight, is now available for testing. I’ll add videos throughout the day.

There are three bosses. The final boss is Archbishop Benedictus — if that surprises you — you should read World of Warcraft: Thrall, Twilight of the Aspects to find out why he’s the last boss of this dungeon.

With the Dragon Soul retrieved from the past, the Heroes of Azeroth now prepare for the final confrontation with Deathwing. In the frozen wastes of Northrend, the towering spire of Wyrmrest Temple is under the assault of Deathwing’s Twilight forces. In order to save Azeroth, Thrall must arrive safely at the temple with the Dragon Soul in hand.
