Journey of the Spark takes place in-between Seasons 2 and 3 of the Friendship is Magic continuity.

The film takes place just a few months after “A Canterlot Wedding” and tries to piece together events from the show that will not only lead into “The Crystal Empire” but “Keep Calm and Flutter On” and eventually Twilight’s growth as portrayed in “Magical Mystery Cure”

That’s not to say that it isn’t without its own original twists as the movie completely strives off of making itself a stand-alone story that anybody not familiar with Equestria and its history can jump straight into.
