WARNING:Rewrite in progress!
As a last vindictive act Discord sends one of the Mane Six into the Multi-verse. The one to suffer this fate is Twilight. She somehow suvives the experience but comes out a filly with very little in terms of memory. Her situation is made much more better by being found by a society and a Human willing to take her in. However this is not so much a story of her life in her new home as a story of how she comes to terms with her old one.
This is the Story of Erika Gefallen as she struggles with the life and memories of Twilight Sparkle...
