Black unicorns were fiendish versions of their good unicorn brethren, magically created by the Red Wizards of Thay. They became prominent in the armies of Thay, serving as elite cavalry.[2]

Black unicorns would only allow human or drow females of an evil alignment to ride them. It was believed they particularly enjoyed serving blackguards.[2]
