Unicorn

Unicorns were magical and majestic equine-like creatures that dwelled exclusively in Narnia.

Notable Unicorns
Unicorns were present at several important events in Narnian history. They were members of Aslan's Army during the Winter Revolution, and at least two were sent with Edmund's rescue party when he was held captive of the White Witch. Peter also rode a unicorn into the Battle of Beruna.

Jewel the Unicorn was a loyal follower of Aslan during the Last War of Narnia.

Characteristics
Unicorns were such noble and honourable creatures that "not even a king would think of riding a unicorn except in some great need." All known Unicorns were fiercely loyal to Aslan, and were often known for their wisdom. In battle, they were fierce opponents, and few enemies could deal with the attack of their teeth, hooves and horn all at once.

As was said of Jewel the Unicorn by one historical chronicler:

"He was so gentle and soft of speech that, if you hadn't known, you would hardly have believed how fierce and terrible he could be in battle."

- C.S. Lewis

Appearance
Unicorns resemble a horse, which is usually white, with a single large, pointed and spiraling horn projecting from its forehead.
