Molten Core » Zones » WoW Armory Light

The Molten Core is located beyond Blackrock Depths within the deepest part of Blackrock Mountain. It is the home of the Firelord Ragnaros — one of the four elemental lieutenants of the Old Gods — and his elemental minions. Molten Core is a 40-man raid and requires "attunement" to enter. The one-step attunement quest is called Attunement to the Core and requires a run through almost to the end of Blackrock Depths to complete. Once attuned you can access Molten Core by talking to Lothos, the questgiver, again.
