Generations ago, humans that settled in the pockets of space in universe weren't actually humans.

They were originally ponies, each bearing a specific mark on their flanks that symbolized their talent. They had been forced to leave their home world due to environmental and planetary changes beyond their control. They left the planet in three unique arks, one for each of their beloved princesses. Twilight, instead of receiving a vessel, took charge of the fleet, and they all vanished into the cosmos.

But Fate was not kind to the traveling horses who had never once left their home world. A stray meteor shower damaged the Celestia, sending her and her crew to edges of space. Before the great ship came to rest, the crew was placed in suspended animation, and the most valuable members, Twilight and the Mane 6, boarded escape pods and scattered themselves across the stars.

Now, centuries later,Twilight the Third and her loyal pilot Spike come across the Celestia. But they're not the only ones who've found the vessel.

It's up to Spike , Twilight, the Mane Six, and Celestia to find the missing two arks, fight off Discord, and find Eques, so they can return home.
