At Discord's urging, Princess Twilight hops on through the mirror portal to Canterlot High, which had been closed for two millenia. Instead of a school, she finds herself in a cargo bay of a starship. Discord also has popcorn at the ready.
Transported away from their home far across the galaxy to a planet called Earth, Sunset Shimmer and Twilight Sparkle must devise a way to cope, learn, and find their way back home to Equestria, by joining Starfleet.
After reforming, Discord has been living with Fluttershy. He's established genuine friendships with some of the Mane 6 and has been working on re-connecting with Celestia... until the day he's arrested by the Q Continuum.
Ponyville hosts some new guests, only they aren't ponies. They also really don't want to be seen, for some reason. What's a Princess to do when aliens are sneaking around?
The Enterprise is on a mission into the Equine anomal, a region of space where subspace technology doesn't work, and many travellers report being watched in their dreams by a blue, horse-like creature.
Discord decides it's about time that the mane 6 met his old friends. What will happen when the defenders of Equestria meet the crew of the Starship Enterprise?
After suffering a fatal wound, Twilight finds herself in the afterlife, where she encounters Discord. The Spirit of Chaos then offers her a chance to prevent her death by changing an event in the past.
