Lady of the Green Kirtle

The Queen of Underland, also called the Witch-Queen or the Green Witch, was an evil, beautiful sorceress who lived in Underland below Narnia. She had the ability to transform into a Great Green Serpent and attempted to initiate a plot that would capture Narnia which involved the abduction of Prince Rilian, son of Narnia's king Caspian X. She is also beilieved to have been Jadis, the White Witch. This is believed because even though she was killed by Aslan, she ate the Apple, allowing her immortality. She was Queen of Underland and planned to conquer Overland, including Narnia, Archenland, and Calormen.
