Griselda

Griselda was a female Griffon who lived in Griffonstone during the Era of Twilight.

Behind the scenes
Griselda's design was later reused for a background Griffon in "The Last Problem", dubbed "Rockin' Griffon Friendship Student" in My Little Pony: Magic Princess. Given the time gap, it is most likely that this is either a coincidence or that the Friendship Student is a relative of Griselda, as opposed to Griselda herself enrolling as a student at the School of Friendship.
