Prepare For Blackrock Foundry

Players of World of Warcraft have braved the Dark Portal and taken on the Iron Horde all across Draenor. They've pushed their way into Highmaul and taken on the challenges within. Now in just a few short weeks, a new challenge will await them as they begin to lay siege against the forces at the Blackrock Foundry, working their way to face Blackhand the Destroyer.
