Shadowforge City is the capital of the Dark Iron dwarves. The city is located in the depths of Blackrock Mountain and lies above the Molten Core — where their master, Ragnaros the Firelord and his flamewakers reside. The city has a world famous inn — the Grim Guzzler — and is the only place in the world where you can smelt Dark Iron. Shadowforge City is in constant conflict with the Blackrock clan and their black dragon masters.
