|   SSxSSSSSSSSSs   |  A river of molten rock flows here! The heat is searing
|   xxx@@@@xxxsss   |  as the red-hot lava flows by. An acrid smell hangs in
<   xxx@@@*xxxsss   >  the air, and noxious fumes of sulphur and soot burn
|   xxxx@@xxxssss   |  lungs and eyes alike. This terrain is so hostile that
|   xxxx@xxxxsxss   |  no natural beings may survive here. A torrent of fire
|     x@@xxxssx     |  ore is embedded in the ground.
