Ironforge is the capital city of the dwarves, a member of the Grand Alliance. It is the ancestral home of the Bronzebeard dwarves. King Magni Bronzebeard rules his kingdom of Khaz Modan from his throne room within the city, and the High Tinker Gelbin Mekkatorque, leader of the gnomes, has temporarily had to settle down in Tinker Town after the recent fall of the gnome city Gnomeregan.
The city is perhaps the most intricate of the Grand Alliance cities, boasting many small passageways, shops built into the rock walls, great halls and cavernous rooms. The feel of the city is a bustling, rowdy, and somewhat industrial one, however, it is predominantly safe-feeling and cozy; fires roar in the hearths of the inns and shops, the sounds of smithing go on as fires roar in the blacksmithing forges, and much dwarven laughing and frivolity is to be heard. Also, unlike Stormwind, Mirkwood, Darnassus and Aranor, the city is actually a massive cavern carved into the earth by the dwarves; the ceiling and floor are both hard stone. This gives the place a sanctuary-like feel.
Ironforge is structurally a giant circle of sections, it also contains several "depth" levels (at least eight, though they are not accessible in game). The accessible portions of Ironforge appear to be located on the 5th level, the "fifth depth" of the city.
