300 years ago, on the day of a solar eclipse, the two alicorn sisters disappeared. Equestria was in chaos, with no pony to lead them, so, thirty teams consisting of three ponies, one unicorn, earth pony, and Pegasus were deployed to find them. present day, princess twilight sparkle rules Equestria much like Celestia did. over the years, the importance of the search slowly but surely died down, and today, only four of the original thirty teams, now called seekers, are deployed in search of the now long lost sisters. one of the seeker teams, number three, has been missing for over three months now, and is presumed dead. Princess Twilight must now deploy another team in their place.
