* The Wicked Witch of the West: She is the main antagonist, sister of the Wicked Witch of the East, and the most powerful of the witches.
* The Wicked Witch of the East: She is killed by Dorothy's house landing on her, setting the plot in motion. It is implied she was the sister of the Wicked Witch of the West.
* The Good Witch of the North: She helps Dorothy on her journey, giving her magical slippers that belonged to her sister. She seems to be related to the two Wicked Witches, but the exact nature of their relationship is unclear.
* The Good Witch of the South: She is only mentioned in the book, and her fate is unknown. It is implied that she had a connection to the other witches as well.
Key Points:
* Sisters: The Wicked Witches of the East and West are explicitly stated to be sisters.
* Family ties: There is a strong suggestion that all four witches are related, perhaps even sisters.
* Good vs. Evil: The good witches are not necessarily benevolent, but rather hold the power to be either good or evil. They seem to be more aligned with the forces of good.
Important Note: The relationship between the witches is a source of some debate and speculation. Some argue that Baum intended for all four witches to be sisters, while others suggest that he left the exact nature of their relationship vague.
Later adaptations: In later Oz books and adaptations, the relationships between the witches are explored further, sometimes adding complexity and depth to the original story.
