"Becoming a Alicorn wasn't the hard part. Its watching everypony you love die. Knowing you will never see them again."
For thirty years, these thoughts have haunted Twilight Sparkles mind. Thirty years to the day she lost the last of her friends.
Now, after coming across the Nightmare, a century after defeating it the first time. She comes to a realization with the help of the other princesses, if it gets a host. They cant stop it.
The elements of harmony, once bright beacons of light now lay dull, cracked and broken as she cant wield the last gift of her friends. A trip to Ponyville will lead Twilight back to the past. To help rediscover the elements.
But what if it's already too late?

What would you do if because of one mistake, you find yourself unsure of what to do?

Follow Skyshine as she experiences this and with the help of friends. She will overcome this, and help the pony she carries to shape the world one day

Remembrance

Summary: If you had to choose between friendship and forever? What would you decide?

One hundred years…one hundred years had passed since the last time Twilight had seen any of her friends in the flesh. It had been even longer since she had last seen the mare that captured her heart. Now, she goes to the vault of harmony and friendship, despite Celestia warning her not to do something irreversible. Something which she hopes will reunite them all, regardless of consequences or cost.
