The Irish legend of the Dullahan, or English translation "dark man" is unnerving. The Headless Horseman or Dullahan is the Irish foreteller of death. The Dullahan rides a jet black horse with flames shooting from its eyes, carrying his head under one arm. Irish folklore says that when he stops riding, a human dies.
There are many versions of this scary tale. Some say that the Dullahan throws buckets of blood at people he passes, while other say he simply calls out the name of the mortal that will soon die.
But as with most evil entities the Dullahan has a weakness. The Dullahan can not stand the sight of GOLD.
