They are horselike animals with gold cloven hooves, a golden mane, a gold tail and a golden horn.
Unicorns are very shy in the prescence of ANYTHING. So they're always shy. Because men hunted them for their horns, they hate male humans but don't mind women so much.
Quite unknown, apart from their magical powers. Unicorns can purify polluted water just by treading in it. Their horns, ground up and mixed with water, make an antidotal elixir.
Iron burns them. Are also allergic to dark magic. Just getting near some of it makes them die.
Deep in the Brow Mountains, under the Benu's protection.
