the unicorn is the symbol of beauty, perfection, love and courage, it can only be seen by those that are pure at heart and selfless. the unicorn was said to be the first creature that was named by adam, and so god placed it before the other creatures, it also was the only animal that was selfless enough to go with adam and eve when they were sent from the garden of eden.
Unicorns love their privacy. They are very wise and like be left alone to live with nature and practice magic. Unicorns are pure and hate being around things that aren't. They hide from anything that is evil or greedy. They distrust humans, we have killed unicorns for their horns.
