Unicorns are a creature supposed to be mythical. The ones in myths are typically breathtakingly beautiful, and their horns are known to have magical properties. Unicorn blood will keep a person alive, or immortal even. While this type is not real, there is a unicorn that is. It is actually rather ugly, with no magical powers, but it is the national animal of Scotland. Look this up; you’ll see it’s true.
Other small fact: Marco Polo thought rhinos were unicorns!
