It's been two years since the two sisters have retired and Twilight took over their royal duties for them. While there has been much peace and prosperity, as well as most of Equestria's enemies either being permanently defeated or have turned over a new leaf like Captain Goodking, it appears they still have one more threat to deal with. But Twilight and her friends aren't taking on Kronos and his alien army alone. They have a Time-Turner on their side! Oh, and Captain Goodking as well but he won't be useful until later on.
Special thanks to DmitriTheWriter for editing this story and for giving me the idea of the Seals of the Planets and Kronos (actually considering making him co-writer). And why yes, that is Korriban (or Moraband, as some people in the galaxy like to call it) that some but not all of our characters are on. If you don't think the possibility of our heroes facing Sith Lords is awesome enough, I also got ADVENT!
