Depiction in the series
Amethyst Maresbury first appears in The Crystal Empire - Part 1 when Twilight Sparkle and her friends go to the Crystal Empire library looking for information on how to protect the Empire from evil. Though Amethyst appears to be the librarian, the effects of King Sombra's curse leave her with partial amnesia, and she is unsure if she even works at the library.

Later in the episode, Amethyst comes out of the library when Twilight announces the Crystal Faire. While at the Faire, Amethyst regains her memories and explains to Rainbow Dash the entire purpose of the Faire and the true nature of the Crystal Heart.

In Flight to the Finish, Amethyst Maresbury briefly appears in the stadium crowd at the Crystal Empire after the Cutie Mark Crusaders' flag-carrying audition. She is also seen talking to a pair of Crystal Pony foals in Twilight's Kingdom - Part 1.
