Jadis (the White Witch)

Within the published sources supplied, Jadis is presented as a literary character created by C. S. Lewis who appears in The Magician's Nephew (1955) and The Lion, the Witch and the Wardrobe (1950). The materials identify her as an originating figure in those books; the provided summaries note her role in Narnia (including her freezing of the land) but do not supply extensive canonical detail beyond naming the works in which her origins and actions are narrated. The supplied sources therefore treat her origin as literary—an antagonist introduced by Lewis—without offering further primary-text excerpts on the mechanics of her arrival into or rise within Narnia in these notes.

The provided source material does not include a detailed physical description beyond the epithet 'White Witch.' The summaries in the supplied sources consistently refer to her by that epithet, identifying her as the Witch who froze Narnia, but do not provide canonical specifics about stature, clothing, or accoutrements in the excerpts given.

According to the supplied summaries, Jadis exercises potent sorcery within Narnia; most prominently, she is described as having 'froze Narnia in the Hundred Years Winter,' establishing and maintaining a prolonged winter. She is consistently characterized as a ruling, malign magical figure and the main antagonist of the cited novels. The archival items that reuse the name do not contribute additional canonical abilities in Lewis's texts within the provided material.
