Celestia has gone too far...interfering with her sister Princess Luna's wedding plans, looking with contempt upon her subjects and now she has murdered the ruler of the Crystal Empire. Stopping her will be the most painful thing Luna has ever done.
Do you remember the three nights of darkness when Luna refused to raise the moon and bring out the stars? It was a thousand years ago, but her heart will never heal nor forget.
After seeing what happened when she accidently changed her friends destinies, Twilight is curious about about the 'what if'. Like, for example, what if Luna had ponies a thousand years ago who noticed her.
One day, the Crusaders happen upon Ponyville’s newest, specialty flower vendor: a young mare from Alemaneia named Schneeblume. They think she’s hiding something. Turns out she is, though not in a way they expected at all.
