The Three Maidens of the Unicorn

"Taxonomists have fought over the classification of unicorns for generations. They constantly switch between Fey and Celestial in our encyclopedias.  What can be said, however, is that unicorns have an immensely positive influence on the land they reside in.  There are also rumors that these magical creatures may even be able to make contracts with mortals, not unlike those made by Outsiders and Fiends." --Scholar of Magical Creatures
