Describe Lucy in the story

Lucy is the youngest of the children, and the first to discover Narnia. In spite of the fantastic nature of her story, she is a truthful girl and takes her experience, as well as her friendship with Mr. Tumnus, very seriously. She demonstrates her loyalty to him when she insists that her siblings find a way to help him, since he saved her from the White Witch, thereby sacrificing himself. From Father Christmas, Lucy receives a dagger and a special bottle of the juice of the fire-flowers that grow on the sun, which she later uses to heal Edmund.

Lucy's observations throughout the story are striking because although she is the youngest of the children, she is also the most observant and prescient. She notices the beauty and patience in Aslan's face in the moment before his death, and tells Susan that Edmund must know what Aslan has done for him.

When Lucy assumes the throne, she becomes known for her golden hair and charm. The people call her "Lucy the Valiant".
