SCP-990 is a mystery to the Foundation. Known as the "Dream Man", he goes making predictions in people's dreams, then those predictions would become reality. However, SCP-990 got to Equestria, but still he still in dreams, but now goes through visions whenever a fog or mist comes up.

Luna, Mistress of the Night and Dreams, will find herself baffled when learning of a mysterious figure, who makes predictions that will turn into reality.

Trapped in the endless halls of Tartarus, forced to listen to the endless screams of rage and regret; an artist grins.

Royalty had put him here, and royalty would let him out.

A deal here, a concession there, and openings would appear.

A crack could break a marble statue, a drop of poison could ruin a meal, the smallest of errors could bring down anything.

It's been a hundred years since the fall of Hyrule. Link has finally woken up from his enchanted sleep, and is ready to save the day. All he has is a piece of ancient Sheikah technology, an old man who won't ever give him a straight answer, and no memory of who he is. Everything is going well.

At least, until his ancient technology accidentally summons a talking purple pony from another world. With neither of them knowing how to get her home, they're stuck together on an adventure to save Hyrule and try not to die in the process.

After an experiment with the Elements of Harmony goes awry, Applejack awakens in a whole new world. With a whole new body. Now, with nothing to her name but her element of harmony, Applejack must find a way back to Equestria, with the help of a certain fortune hunter named Nathan Drake.

(A/N: Hi there, so this story marks a couple of milestones for me. Not only is it my first humanised fic, it is also my first proper crossover. If you find any mistakes or you have any suggestions, feel free to let me know. And thank you.)

“And it's something quite peculiar,/Something shimmering and white./Leads you here despite your destination,/Under the Milky Way tonight.” –The Church, ‘Under The Milky Way’

While stargazing late one night, Twilight Sparkle notices a mysterious object falling from the heavens and landing just outside of Ponyville. Allowing her curiosity to get the best of her, Twilight goes to investigate, and what she finds surprises her. She finds a brown stallion on the inside of a blue wooden box. Who is this pony and why does he ask Twilight to trust him?

What's it been? 1000 years?
That's funny. It feels like much longer than that.

Let me tell you, being trapped in stone that long can do crazy things to a guy.
And when you were a little off your rocker in the first place...
But now I'm free. The leaders of this disgusting place trapped me here, and now they're going to pay.
I'm going to show them the real definition of insanity.

After a teleportation spell gone awry, half of the Element-Bearers have disappeared. Six months have passed, and the Princesses fear that their old enemies may rise up once again.

Fortunately, Twilight, Rainbow Dash and Applejack have finally returned, along with three battle-weary dragons and three bedraggled humans. Battle-hardened and scarred, no one can believe that these are the same mares they used to know.

They tell a tale of world far beyond Equestria. A world where magic and technology are worshipped side by side. A place where a thousand different races eke out a living in the midst of unending combat. And a massive, unbelievably complex world, used as a playground between two vengeful gods.

A place called "Byzantine".

This is inspired by Crossed Paths and On the Wings of Angels. Includes characters from Star Wars, Dresden Files, Skylands, the Dark Tower series, and How to Train your Dragon.
This is a multiversal fic, and features characters and places from all across fiction.

(Wreck-It Ralph/MLP:FiM crossover) A My Little Pony video game is put into the Litwak Arcade, and the characters from the show live their lives as game sprites in a digital world. However, circumstances get serious as Twilight is kidnapped by a desperate NPC from a game doomed to be unplugged. With help from Wreck-It Ralph and Fix-It Felix, they must rescue her before the arcade opens.

In a place filled with fierce dragons, mystical mages, and mighty warriors. In a world called Skyrim a journey begins for one man, but not the exact one you might have in mind. After an attack on Whiterun, a guard is teleported to a colorful world filled with wonder. This journey will change the rest of his life, and maybe also all of Equestria.

Note this is a humanized ponies story. If you do not like these then move along please.

In a remote corner of Equestria, the lessons writ by balefire have been forgotten. For the very same reasons zebras and ponies nearly obliterated each other, the donkeys of Kansass and the ponies of Missurrey stand ready to repeat the past. Into this simmering border war wanders a mule on her own mission.

As soon as she remembers what that mission was...
