The door opens onto a chiseled tunnelway, extending for some distance. Torches flare to magical life as you begin to traverse it, carved into the likenesses of mighty dragons of yore. Up ahead the worked stone gives way abruptly to what appears to be a large natural cavern. A rift cuts across the cavern, with a lone, arching stone bridge precariously crossing the gap. A river of magma flows along the bottom of the rift some 60 feet down.<br/><br/>The air in the cavern is hot, and the red-orange glow of molten rock illuminates the walls of the chamber. Strange shapes and shadows appear to writhe within these walls, though they could just be distortions due to the heat.As your eyes adapt to the sting of brimstone in the air, the shapes on the walls can be seen more clearly. They bear the distinctive swirls and sharp lines of dragonmarks, though they do not resemble any marks you recognize.<br/><br/>A stone sarcophagus carved with draconic imagery stands along the far edge of the magma rift, with a massive basalt slab lying near the distant wall. Three niches are set into the wall behind the stone slab, two of which appear to hold objects.
