Sulfuron Spire
From Wowpedia
Sulfuron Spire[47, 78] is the fortress of Ragnaros and the entrance to the Firelands, located in the middle of The Throne of Flame at the southern end of Mount Hyjal.
The Inner Spire is presumably inside of it. Unlike other flamegate-entered locations, the Inner Spire appears to be under the spire, and not the flamegate it is entered from.
Notes
- At the base of the spire is the entrance to the Firelands raid.
- The Spire is missing a window on one side.
