Baum spent a great deal of time with his mother-in-law, activist Matilda Joslyn Gage, who encouraged him to write down his Oz stories.

After the Wizard flies away in his balloon, the Cowardly Lion, Scarecrow, Tin Woodman, Dorothy, and Toto travel South to the land of the Quadlings to ask Glinda for her advice.

[citation needed] In the books, Glinda is depicted as a beautiful young woman with long, rich rare red hair and blue eyes, wearing a pure white dress.

She is much older than her appearance would suggest, but "knows how to keep young in spite of the many years she has lived"—a fact that is established in The Wonderful Wizard of Oz, by the Soldier with the Green Whiskers.

The Emerald City of Oz reveals that she owns a Great Book of Records that allows her to track everything that goes on in the world from the instant it happens.

She creates walled, gated communities for the rabbits of Bunnybury and the paper dolls of Miss Cuttenclip, showing a personal interest in the concerns of not only the humanoid Quadlings, but also the other inhabitants of her jurisdiction.

However, unlike Ozma, Glinda is willing to ignore strife and oppression in remote corners of Oz like Jinxland and the Skeezer territory as long as it does not threaten the Emerald City or innocent outsiders.

As mentioned above, he is not an expert on Oz, but this statement made by Guph once again foreshadows a much later cinematic rendition of Glinda, in the film version of the Broadway musical The Wiz in which Glinda (played by Lena Horne) and the original (played by Billie Burke) is responsible for the twister that brings Dorothy's house to Oz and sets all subsequent events into motion.

[citation needed] In Philip Jose Farmer's novel A Barnstormer in Oz, Glinda is portrayed as young and beautiful enough to attract the protagonist, though the interest is not mutual.

[citation needed] In Gregory Maguire's 1995 revisionist novel Wicked, she is initially called "Galinda", and (through her mother) is descended from the noble clan of the Arduennas of the Upland.

Though originally snobbish and superficial, she is also intelligent enough to be accepted to Shiz University's Crage Hall, where she is assigned to share a room with Elphaba.

She is able to summon the powers of "all the good fairies" when restoring Princess Ozma to her rightful form, almost making her equal to L. Frank Baum's Queen Lurline (whereas Baum's Glinda is a stately sorceress showing no association with fairy magic or "unscrupulous" witchcraft, insisting that the witch Mombi herself disenchant Ozma unlike in this film).

In L. Frank Baum's novel, The Lost Princess of Oz, the Wizard says: "Ozma is a fairy, and so is Glinda, so no power can kill or destroy them, but you girls are all mortals and so are Button-Bright and I, so we must watch out for ourselves."

She sings a climactic song called "You Have Only You (To Look To)" to Dorothy, making her look inside herself for the strength that is not forthcoming from old companions such as the Tin Woodman and the Cowardly Lion.

After restoring Princess Ozma to the throne, Glinda uses her magic on Mombi and Jinjur to make them reform, when the witch and the rebel queen refuse to mend their villainous ways.

As the series draws to an end, Glinda telepathically contacts and saves Dorothy from falling to her death from a tower, following a confrontation with the Nome King and his minions.

Actress Sheryl Lee portrays a version of the Good Witch, who appears in a hallucination to Nicolas Cage's character, Sailor Ripley, in David Lynch's 1990 black comedy thriller Wild at Heart.

Glinda persuades Sailor to return to Lula Fortune (Laura Dern), his lover, and Pace, his six-year-old son during an hallucinatory conversation with her near the end of the film.

She is portrayed in a lavender dress with a feather boa, an archetypal Hollywood starlet much more in keeping with the character of Miss Piggy rather than Glinda.

In the film, she helps a good-hearted con artist named Oscar Diggs (James Franco) defeat the sisters and become the Wizard of Oz.

Goodwitch serves as the right-hand associate of Professor Ozpin (whose likeness alludes to the Wizard of Oz) and plays an integral part in training the students of Beacon Academy to protect the world from evil forces.

Only the 4th seat of the sisterhood—representing innocence—remains empty, but through Glinda's guardianship of the Book of Records, a prophecy foretells of a sorceress coming to Oz via a cyclone to join them.

While showing Zelena the western area of Oz, they approach wreckage from a cyclone and take in a girl, Dorothy Gale (Matreya Scarrwener).

In this new realm, she begins living in the north of woods, south of Rumpelstiltskin's (Robert Carlyle) castle, hidden in a pocket dimension of ice and snow, which only the pure of heart may enter through.

Sensing the incoming presence of Snow White (Ginnifer Goodwin) and Prince Charming (Josh Dallas) crossing into her realm, Glinda makes herself known to them.

When Snow White asks for Regina's whereabouts since she was just with them, Glinda states that the Queen didn't meet the qualifications needed for entering through the door.

The Mistress of the North "Maiden of the Northern Light, Mother of the Sound and Pure" and one of the last Cardinal Witches of Oz, Glinda is an authoritative woman who has had a deep-seated hatred towards the Wizard (Vincent D'Onofrio) ever since he outlawed magic.

Since the change of regime in Oz, Glinda also runs a boarding house for orphaned girls where she oversees their education and chooses the best of them to join the Wizard's High Council.

[14] Glinda in this version is called the Sorceress of the North; and Broadway star and ballerina Patricia Bowman portrayed the role in its initial staging.

The two friends struggle through opposing personalities and viewpoints, rivalry over the same love-interest, reactions to the Wizard's corrupt government and, ultimately, Elphaba's public fall from grace.
