Fenris ulf

Fenris Ulf was a ferocious talking wolf, the captain of the White Witch's Secret Police at the very end of the Hundred-Year Winter.

He first led the raid of Tumnus' Cave where the Faun Tumnus was captured and his home left in tatters.

Fenris encountered the human boy Edmund Pevensie while guarding the White Witch's Castle courtyard.

He later spied on Aslan's Camp until being revealed by Susan Pevensie and the sound of her horn. Her oldest sibling, Peter met Maugrim in battle while she fled into a tree. Although Peter at first missed Fenris with his swordtip, as the wolf howled formidably, he was able to then push the blade into Maugrim's heart. The wolf captain died a few moments later, never ceasing his biting and scratching the whole time.

Trivia

 * In early American editions of the book, his name is Fenris Ulf; however, publications that are more recent have reverted it to Maurgrim.
 * Maugrim's name is supposedly derived from the words "maw" (mouth) and "grim" or possibly "morgue grim".
