Blackfathom and Cacodemon

  Whispers of Blackfathom have been heard around campfires and in 
  the taverns of Fantasy for years, but only recently has anyone 
  actually claimed to not only find an entrance to the cave system,
  but survive exploring inside. Of course, none of them faced the
  ultimate reason that the system was built. The Cacodemon. To learn 
  more, visit the Wayhaven library or check out questlist 62.
