Further description below.

Approximately three million years ago, in an age known as "The 90's" a man named Dave Lister worked on a mining ship in space, named Red Dwarf. After discovering that Lister had a cat onboard, a direct transgression of the ship's sanitation rules, the captain of the ship sentenced Lister to two years in stasis. Upon awakening, he finds that he was not, in fact, in stasis for 2 years. He was in stasis for three million. The only life forms remaining are: David Lister, the ships third technician (lowest rank), a hologram of Lister's bunkmate Second Technician Arnold Judas Rimmer, the ship's AI system Holly, a life form that evolved from Lister's cat, and a mechinoid they picked up along the way named Kryten.
Twilight Sparkle lives in Equestria, a world of high-class magical unicorns, fast middle-class Pegasi, and lower-class laboring regular earth ponies, or, if to be disrespectful, earthies. All royalty are alicorns, and the main ruler is Princess Celestia, with the help of her sisters Princess Luna and Princess Cadenza, or Cadence for short. Twilight is Celestia's faithful student, and was sent to Ponyville, a suburban village underneath the Pegasus capital Cloudsdale and also the root of very many problems: the Everfree Forest, to learn more about the magic of friendship. Along this journey she has made many friends, particularly five relatively young mares. These six friends have saved Equestria many a time. Twilight's five friends are Applejack, Pinkamina Pie (or Pinkie Pie for short), Rarity, Rainbow Dash, and Fluttershy. Twilight also has an assistant, a baby dragon named Spike.
