This story is a sequel to Winds of the Past

Before moving to Ponyville, Twilight Sparkle's life was anything but eventful... her usual days chocked full of meticulous planning and rigorous studying.

That was until three years ago, when the ever faithful pupil of Princess Celestia teamed up with five other unique mares to stop the tyrannical Nightmare Moon from bringing about everlasting night. She and her newfound friends had many adventures in the years that ensued, learning all about the magic of friendship: its ups, downs... but most importantly, how it could grow into so much more.

Life is seemingly perfect for the group of six friends, and yet for Twilight... why does everything feel so wrong...? After glimpsing potential memories of herself and her friend Rainbow Dash—that otherwise shouldn't exist—she begins to question whether the life she's known is a lie. Some of her friends start acting strangely whenever she tries to question them, while others downplay her concern or outright deny it. What's more, unfamiliar, yet warm feelings begin emerging for her pegasus friend... painting her longtime friend in a whole new light.

Despite it all, after the Friendship Map pairs both herself and Rainbow Dash up to solve yet another friendship problem, Twilight tries her best to focus on the task at hand. So what if her memories aren't what she thought they were, or... or if Rainbow doesn't reciprocate her feelings? Solving another pony's friendship troubles should come before one's own needs as Princess of Friendship.

Only... why is there another pony who reminds her so much of herself? Not to mention a "negative" her, with a grudge against all of alicornkind and a plot to unify all worlds under her control? And how exactly is Starlight Glimmer involved in all of this? Just what in the world did she forget!?

What was supposed to be a simple friendship problem soon turns into a fight for the fate of all realities. Faces old and new, strange and familiar join Rainbow and Twilight in their struggle to reclaim their lost past, and overcome insurmountable threats in a battle for their very future.
