Here's the breakdown:
* Maugrim is killed by Aslan, the lion king, in *The Lion, the Witch and the Wardrobe*. This is a pivotal moment in the story, symbolizing the defeat of evil and the triumph of good.
* There are other wolves in Narnia, but Maugrim is the most prominent and the only one explicitly killed in the series.
While there are other wolves that feature in the Narnia stories, none are explicitly killed. It's important to remember that while Maugrim's death is significant, it is not the only act of violence in the Narnia chronicles.
