Jinn

The Jinn is a supernatural race from which the White Witch Jadis inherits one side of her lineage, a fact that Mr. Beaver reveals to the Pevensie children during their conversation in the Beavers' house. This revelation is crucial for understanding the Witch's nature and her claim to the throne of Narnia.

Lineage and Nature

Mr. Beaver explains that the White Witch is not a Daughter of Eve, despite her human appearance. She comes, on one side, from the Jinn, specifically from Lilith, who was Adam's first wife. On the other side, she descends from the giants. This mixed heritage means that there is not a single drop of true Human blood in her. Mrs. Beaver affirms this, stating that this is why the Witch is "bad all through." Mr. Beaver elaborates on the danger of beings that look human but are not, advising the children to be wary of anything that is going to be human and isn't yet, used to be human and isn't now, or ought to be human and isn't.

Significance

The Jinn ancestry is central to the White Witch's identity and her role in the story. It explains her magical power and her cruelty, as she is not bound by the same moral laws as humans. It also undermines her claim to be the rightful Queen of Narnia, as she is not a true human and therefore not the prophesied ruler. The revelation of her Jinn and giant heritage solidifies her as an alien and malevolent force, distinct from the human children who are destined to sit on the thrones of Cair Paravel.
