After Twilight earned her wings, she came to the harsh reality that her friends and family would eventually die, and she'd live on without them. She'd have to go on without her best friends for the rest of her immortal life.
A few thousand years after their deaths, Twilight is still extremely depressed and mourning their deaths.
Twilight will never be able to spend a single second with them ever again.
But then, while exploring the Castle of the Two Sisters like she used to with her friends, she finds an old, magical amulet.
Thinking it was just another of the several lost ancient charms, she thought nothing of it, but kept it to figure out what it is.
Little did she know, she's in for the shock of her life.

After a visit to Manehatten, Diamond Tiara and her father, Filthy Rich, return home. But when they get off the train, they discover that Ponyville is deserted. And to make matters worse, Filthy Rich goes missing in mere minutes upon arriving home.

What will become of Diamond Tiara as she timidly explores the now abandoned town alone?

... But is she really alone like she thinks she is?
