Jadis, commonly known during her rule of Narnia as the White Witch, is the main antagonist of The Magician's Nephew and The Lion, The Witch and the Wardrobe in C. S. Lewis' Chronicles of Narnia series. She is the Witch who froze Narnia in the Hundred Years Winter.
Some recent editions of the books include brief notes, added by later editors, that describe the cast of characters. As Lewis scholar Peter Schakel points out, the description there of Jadis and the Queen of Underland "states incorrectly that the Queen of Underland is an embodiment of Jadis". Beyond characterising the two as "Northern Witches", Lewis's text does not connect them. (See Lady of the Green Kirtle for further discussion.)
The White Witch was born before the creation of Narnia and died in battle in Narnian year 1000.
In The Magician's Nephew, Jadis is revealed to be a native of Charn, a different world entirely from Narnia. She is descended from a long line of king and queen. This line began well, with honorable, decent-hearted people, but grew evil and malevolent over many generations. Charn's final queen, Jadis, a powerful sorceress, fought against her sister in a bloody war which almost ended in her own defeat. Rather than submit to her sister, Jadis spoke the Deplorable Word and left Charn devoid of life. She passes through the Wood between the Worlds, an endless forest filled with pools of water that act as portals to other worlds, including the worlds of Earth and Narnia. Charn is destroyed so utterly that when Jadis leaves its pool in the Wood, the pool dries to nothing. While in the Wood, she appears to lose health, strength and magical ability. Through the reckless actions of Digory Kirke, Jadis is transported to the world of Narnia at its creation, and she immediately starts scheming to become its mistress. She eats the Fruit of Everlasting Life, acquiring immortality and her white-colored skin; she then travels to the North to develop her magic anew, becoming the first of the "Northern Witches".
