Blackrock Spire

Blackrock Mountain was home to a lot of end-game content during vanilla-era World of Warcraft, were everyone would gather to run Blackrock Depths, Blackrock Spire, Molten Core, and starting in patch 1.6.0, Blackwing Lair.

When last we talked about the Dark Iron Dwarves, Sorcerer-Thane Thaurissan had just summoned Ragnaros and destroyed himself and the city that bore his name in the process.

Update: Blackrock Spire is now open and available for play.
