      |   Once a source of great wealth for the Drow who inhabit    |
      |  these parts, this mine has now filled with a strange,      |
      |  thick grey fog. The mysterious source of the fog yet       |
      |  eludes the drow patrols. Surely something lurks in the     |
      |  abandoned depths.                                          |
