Bored, Eric Reed asks Starlight Glimmer to cast a spell to let him use magic once again, and later decides to train him a bit by teaching him more spells. When Trixie stops by, Trixie decides to "test" Eric's new magical abilities with a friendly "magic duel" with her. He proves to be better than she thought, and with Trixie's pride on the line, it becomes a more and more heated duel.

While this isn't a "sequel" to it, this story does take place after the events of my "A Giant Adventure to Equestria" story. Here's the link to it.
