Hollow Mountain, named for the many caverns and tunnels that snake beneath it, stands in the gloomy Voormithadreth Mountains just beyond the Grimshaws and is the subject of many rumors and legends. Treasures are said to lie deep below the mountain, perhaps the horde of a greedy dragon, but few have successfully explored more than a small fraction of the dangerous passage.
