The story is generally the same. A group of ponies go on a quest to stop an insane alicorn who had escaped banishment, learning about friendship along the way and mastering the Elements of Harmony. But the details...

It can be Trixie Lulamoon leading the Elements of Harmony against Corona.
Rainbow Dash could be Celestia's student and go to Ponyville.
Equestria could have a deep connection to three young people in its distant past.
The Elements of Harmony could have been moved to Manehattan for the ponies to quest for.
Princess Cadance might rule over an Equestria of music, with Octavia as her prized protege.
Or Spike and Twilight might have their roles reversed, the former a stallion and the Element of Magic.

And each one has been chosen by Discord, an Element removed to a seventh Equestria for purposes as yet unknown. Can they survive? Can they get home? Read and find out!

Inspired by the story image, RainbowDoubleDash's Lunaverse and Trinary's "Rainbooms and Royalty", I give you my take on the alternate universe concept. Namely, a universe where Spike is the pony and Twilight is his dragon assistant.

The thousandth Summer Sun Celebration is approaching. With it will come the return of Nightmare Moon. Celestia has no student to call upon to save Equestria, and is doing all she can to make the last day of peace meaningful for her people.

Meanwhile, Spike "Purple Prose" Flail is a reporter for the Canterlot Sun. He finds himself being shipped down to the boonies with his longtime friend and assistant, Twilight, to cover the biggest festival Equestria has seen in a millennium!

But even with a visit from the princess, there's no way someplace as boring as Ponyville could ever be newsworthy. Right?

Story would also include character tags for Thunderlane and Cheerilee if not for the character tag limit.

This story is a sequel to Flipside

((A sequel to my surprisingly popular story Flipside! Set in an alternate universe where Spike is the pony and Twilight is his dragon assistant.))

It's been two weeks since the defeat of Nightmare Moon. Two weeks since six unexpected ponies became heroes that saved not only Ponyville, but all of Equestria. And in those two weeks Spike "Purple Prose" Flail, ace reporter for the Canterlot Sun, has had plenty of time to get into the swing of his new home in the small town. Life seems good...

Until a new pony blows into town. A specter from Spike's past that isn't willing to let him just have his "happily ever after." A certain ex-student of Princess Celestia herself that Spike hasn't thought of in ages.

One who's particularly eager to show how little a "hero" Spike is.

Part of the Flipverse!
