Throne of the King of Embers

Publisher's blurb:

The chamber extends some three hundred feet, two sets of staircases are on either side of a broken bridge leading down into a bumbling pit of magma and noxious fumes. The bridge has fallen in multiple places along it’s path, leaving it’s iron chains hanging down from it’s railings to the roiling lava.

Smaller walkways hug the edges of the chamber and lead past many broken and crumbling crypts, in places these walkways too have collapsed. After passing through the chamber you reach it’s end. A throne of bone and iron surrounded by the tombs of four others and two pools of molten rock.
