Taking place three years after the events of Winds of the Past, Rainbow Dash and Twilight struggle to hold onto a relationship that had long since been forgotten.

A year before moving to Ponyville, before making friends... a certain rainbow-maned pegasus mare crashed through Twilight's window, and into her life. Left with bruises, and a case of amnesia, Twilight soon finds herself looking after the stranger.

In another world wrought with disaster, and ravaged by conflict and war, Twilight Sparkle finds herself at wits' end from suffering heartache after heartache, and finds herself longing to return to a simpler time, when friendship was magic. Her past.

There's one thing Twilight just can't seem to figure out. Why does Rainbow Dash have a rainbow mane?
