Werewolf

"I'm hunger. I'm thirst. Where I bite, I hold till I die, and even after death they must cut out my mouthful from my enemy's body and bury it with me. I can fast a hundred years and not die. I can lie a hundred nights on the ice and not freeze. I can drink a river of blood and not burst. Show me your enemies."

- An unnamed werewolf that tried to kill Caspian.

Werewolves were creatures capable of transforming from a presumed human-like appearance to that similar to a wolf.

Werewolves, along with Ogres, Boggles and Hags, were considered among Narnia's darkest and most evil of races.

Biography
During the Long Winter, they served the White Witch, and were present at the sacrifice of Aslan at the Stone Table. They also fought for her army in the First Battle of Beruna, where they and the White Tigers were the first to directly engage Aslan's army; one of them was taken down immediately by a Leopard.

Because they were considered among Narnia's darkest creatures, they were most likely some of the White Witch's most valued servants. They were certainly some of her most loyal, as they remained so to her right until the days of the Narnian Revolution, 1300 years after her death. It is unknown how werewolves entered Narnia; they were probably creations of the White Witch.

"We should not have Aslan for a friend if we brought in that rabble."

- Trufflehunter describing Werewolves.

In 2303, when Caspian X joined the Narnians to help take down his uncle, the usurper Miraz, a werewolf and a Hag tried unsuccessfully to convince him to summon the White Witch back to life, to help rid them of King Miraz. Caspian refused, and a fight broke out between them, resulting in the creatures' and Nikabrik's deaths. The werewolf was among the casualties, but not before biting Caspian.

Facts/Myths
Werewolves have the ability to turn from a man to a wolf at will.

The myth goes that one had only to be bitten by a werewolf to become one, but apparently, as Caspian was bitten and yet did not change, this myth is not true for Narnian werewolves.

Most werewolves are also thought of wearing gray fur, but Russians are scared of werewolves and believe it's the white wolf who chooses who shall join the werewolf pack next, This happens with Russians who argue with Native Americans up in Alaska when a wolf pack might be running near someone's house. Russians think if the person the white wolf touches is close to touching a relative then that person will change into a werewolf as well.
