This story is a sequel to Antipodes

Several decades after the heroic actions of Jigsaw, Tiptoe, and Incendia restored the princesses, the world has begun the slow process of healing. Spectrum is a headstrong young stallion from Totemhoof who signs up with an excavation team in the hopes of experiencing a life changing adventure. What he finds will send him into a head-on collision with forces he can't begin to comprehend- and, perhaps, a chance to fulfill his destiny.

Sequel to Antipodes- though you don't need to have read it to enjoy this, I hope.

AKA An2podes

Set in the far future after Celestia and Luna mysteriously vanished and the sun and moon froze in the sky, Antipodes is the story of two ponies thrust out into the harsh new world on an adventure to uncover what happened to the world so long ago.

A thousand years is quite the generation gap, so Princess Luna decides she has to get with the times. However, this isn't quite as easy as she thinks it will be...

Spike only wants things to stay the same. Time, however, has other ideas. He's going to need a lot of help... An everypony story.

A horrible Cataclysm has turned all of Equestria into a Wasteland of barren ash and twilight desolation. The Sun and the Moon have been destroyed. Everypony has died--including Princesses Luna and Celestia. But one pony miraculously survives; she is a lone wanderer, the last of her kind, surrounded by menacing creatures that hate her. She navigates the Wastes in an airship and scavenges off the blighted landscape to keep herself alive.

Then one day she meets an old companion who grants her a gift, the chance to go back in time to the warm and sunny days of Ponyville, where her dead friends live in happiness. How far will the last pony venture into this joyous age of Equestria, even if she fully knows that there is no way to change the horrible fate of everypony she loves?

Distance can drive us apart. It can also bring us closer together.

After all is said and done, and the ponies have gone their separate ways, the only way they have to keep in touch is through letters.
