Twilight Sparkle has always been the faithful and most capable student of Princess Celestia. There has never been a challenge too great for her, nor a single villain who could shake the foundations of her loyalty. When she is sent to the Crystal Empire to complete a test, she finds herself in a comprising position.

Waking up in a jail cell, she is now the prisoner of evil King Sombra. However, not everything is what it seems. Secrets of the past reveal to show that neither Sombra nor Celestia is what history makes them out to be. Is this new truth enough to shake Twilight's loyalty for the princess she always considered to be kind, tolerant, and compassionate?
