Blizzard has revealed that patch 2.1.0 for World of Warcraft will introduce the Black Temple as an instance, home of Illidan The Betrayer.
It's he who rules over The Outlands - the new zone introduced in The Burning Crusade - so expect it to be a hardcore instance, probably a 25-man raid affair.
Alongside the new dungeon is an vast slog of class updates and fixes, tweaking the tidal-wave of new stuff that the expansion added. There's also a new PvP Arena to explore in The Ruins of Lordaeron, and Epic flying mounts, Nether Drakes, will finally be available.
Druids will be treated to their own Epic-flight form, obtained by completing a freshly integrated quest, which is similar to the Warlock and Paladin Epic (horse) mount quests.
The patch is expected to go live in Europe on Wednesday, and you can get your juices flowing by watching The Black Temple trailer on Eurogamer TV.
Alternatively you can tuck into the full list of changes over on the official World of Warcraft site.
While you're there, you might also want to speculate on the new game Blizzard is planning to announce. The site shows a time-line of the developer's games to date, with a question mark over a new project.
But it looks like we'll have to wait until 19th May to find out whether it really is the StarCraft MMO or sequel that's so heavily rumoured, as Blizzard takes to the stage at its South Korean event.
