She makes her first physical appearance in My Little Pony: Friendship is Magic Issue #58 and her first in-show appearance in the season seven episode A Health of Information.

Depiction in the series
Mage Meadowbrook is first mentioned in the season five premiere The Cutie Map - Part 1 and Part 2, where she is described as a great Eastern unicorn sorceress. In Part 1, Starlight Glimmer claims her "Staff of Sameness" to be one of Meadowbrook's nine enchanted items. In Part 2, Twilight Sparkle states that Meadowbrook only had eight.

In A Health of Information, Meadowbrook is revealed to be a legendary healer known as the "Mystical Mask" and the subject of a folktale that Fluttershy's parents often told her when she was a filly. Long ago, she studied medicine under her mother and kept multiple journals. In one of her journal entries, Meadowbrook contends with a Swamp Fever epidemic that infects her mother and fellow villagers. While searching for a cure, she discovers that flash bees are immune to the disease-spreading flower's poison.

Using her healer's mask to shield herself from the bees, Meadowbrook collects some of their honey and uses it to develop a cure for the epidemic. Afterward, she dedicates her life to helping other sick ponies across Equestria. In the present, Meadowbrook is stated to have mysteriously vanished without a trace one day, and Cattail is her only known descendant. When Zecora comes down with Swamp Fever, Fluttershy cures her by using the notes and healer's mask that Meadowbrook left behind.

In the season seven finale Shadow Play, Meadowbrook is revealed to be one of the six "Pillars of Old Equestria" with Rockhoof, Mistmane, Flash Magnus, Somnambula, and Star Swirl the Bearded, representing the Element of Healing. Long ago, she and the other Pillars were brought together by the unicorn Stygian to battle a great evil. When Stygian later turned into the Pony of Shadows, Meadowbrook and the others sacrificed themselves to imprison him in limbo.

In present day, Fluttershy retrieves Meadowbrook's mask from Cattail for a ritual to free the Pillars from limbo. When the Pony of Shadows is freed along with them, Meadowbrook and the other Pillars team up with the Mane Six to separate Stygian from the darkness and banish it to limbo once again. She and the other Pillars later decide to travel Equestria to see what has become of their old homes and find their place in this new land.

In School Daze - Part 1, Meadowbrook's bust appears in the School of Friendship. In A Rockhoof and a Hard Place, Meadowbrook briefly appears selling potions out of her old Hayseed Swamp home.

In The Ending of the End - Part 1, Meadowbrook and her fellow Pillars face off against Lord Tirek, but they are easily overpowered and drained of their magic due to Tirek being empowered by the Bewitching Bell. In Part 2, she and the Pillars keep Tirek, Queen Chrysalis, and Cozy Glow busy while Twilight's friends escape. She is later present during the final battle against the villains and helps the Mane Six and Young Six defeat them. In The Last Problem, Meadowbrook attends Twilight Sparkle's coronation ceremony. She also briefly appears in Fluttershy's group shot during The Magic of Friendship Grows.

Mage Meadowbrook is mentioned by Fluttershy in one of the latter's past memories of A Health of Information in Memnagerie.
