A millennium ago, give or take, Princesses Celestia and Luna were nearly defeated by the most powerful villain that they had ever faced, Grogar, the dreaded lord of Tambelon. Thanks only to the whims of random chance, the two princesses survived that encounter, but have been forced to live in fear of the time of his inevitable return. That time is now...

...But whatever revival was intended has gone a little... wrong. Behind the wheels of Grogar's body is the spirit of a slightly extremely eccentric human. Equestria would have been lucky to survive the real Grogar, but will the ponies fare any better with this loon ruling Tambelon?

You. Have. Been. Warned.

In a remote corner of the Solana Galaxy lies a backwater planet called Veldin. Nothing important ever happens there. Nothing exciting, either. Ratchet, a Lombax with no idea of his origins, is beginning to grow bored with his life, and dreams of excitement. He wishes on a falling star for some excitement to find its way into his life.

The falling star answers by crashing into his home in the form of a basket carrying a tiny creature with a horn, a pair of wings, and four hooves. The name on the basket reads "Twilight Sparkle".

When a space pilot who's only ever awake from cryo-sleep to perform maintenance and mine resources crashes on an unknown planet, what's he to do? Do what he does best, mine, grind and weld! Then when reports that the planet's he's landed on is not only inhabited by a race of intelligent ponies but is in the last throes of it's life and is threatening to destabilize, everything becomes a race against the clock in order to not only save himself but maybe even the very species he's found himself surrounded by.

MLP/Space Engineers crossover.
Sunset went to the human realm and came back a few years later with Twilight, becoming Twilight's student after Twi's ascension.
Not expecting many chapters or many long chapters. (Hah! Apparently not so!)

Legends tell of the lost land of Equestria, once the home of all ponies. It is said that the Fire of Friendship was born there, and that the land was ruled over by four beings with brilliant souls and powerful magic. Gone are the glory days now. In this ruined world there are only mindless undead, ravenous changelings, and prowling, demonic beasts. The bonfires that keep the peace in the lands beyond Equestria are failing, and as the Fire fades, so too does the strength of nations.

Yet, perhaps there may still be hope. Perhaps, somewhere in the heart of that forsaken kingdom, there may still be a way to break this curse.

A Dark Souls crossover. Expect pain and misery.

Part of the Borderworld.

Two years after the attack on Equestria, Queen Chrysalis finds herself broken and unable to go on, but there is hope. Discord and the original Queen Chrysalis came up with a spell many years ago, bring a girl from another dimension to Equestria, and she would become the new Queen. Though she would have the previous Queen to help her take on the ultimate disguise.
Though this is not all the new Queen faces, a dark force has risen, with power strong enough that even the old queen fears it. Their choices could affect the future of Equestria, and not just for pony and changeling, but every creature! Who will survive? And can something that the Queen has denied for so long, be the key to their success? Read on to find out!

Story takes place during Season 4 of the show. And though we might see background ponies introduced after that or some canon stuff learned after that, most changeling canon now being made in season 6 will either be used if it is still relevant to my plans, or will be ignored. (Changelings hatching into Larva for one example.)
