Unicorns greatly dislike the Aen Elle who forced them to open the gate between worlds so that they might massacre humans from other worlds. They also change color with age. They can move between parallel realities, and they may also move through time (fourth and fifth dimensions). The legends that suggest unicorns can only be captured by virgins are false. In reality they simply despise evil and so, avoid it. They usually appear to people with a good heart.
