A unicorn is a magical equine with a single horn in its forehead. It is good luck to kiss a unicorn's horn, but woe to any fool who harms one.
Unicorns are sometimes used as combat mounts against their wills. It is also known that a royal princess in the Eastlands of the Great Underground Empire was able to charm a unicorn so that she was the only one who could approach and ride it.
A unicorn show
A unicorn show was held in a town near the Castle of Zork.
Most unicorns have fled to the Plane of TransInfinite Splendor, where they enjoy a carefree existence free from the cruelty of man. The unhappy few left behind are eagerly sought by zoos and private collectors. One such private collector in Mizniaport actually had his last unicorn freed by a peasant who was on a quest to recover the Coconut of Quendor.
