They have a single horn, a long plumed tail, and 4 flexible tentacles around their mouths. They may be magical immortals or merely very dangerous wild animals.
The legends say that they do not eat or sleep, can change sex and size at will and can purify water with their horns. They may be captured by virgins, but kill anyone else who tries.
The Merial claim knowledge of them, and more. The Merial claim that unicorns and dragons could interbreed to produce kirini and adelaini. They say that the unicorns tentacles, similiar to the Merials, mark them as a sister race. The truth of this is unknown.
The arrival of a unicorn is said to herald each passing of the Seelie crown to the next King and Queen.
