Rainbow Dash flies east.

Shining Armor is a tooth. Really. Princess Luna says so.

With a reading that had once been done by Scarlett Blade, only now missing (darn).

And a review by Present Perfect.

Tony Stark had everything he wanted in his life. He had his company. He had a carefree life where he could simply enjoy himself and tinker with whatever came to mind...and he was a super hero to boot! He couldn't imagine ever being happier.

And then a rainbow-maned Pegasus foal dropped into his life, and turned it upside down.

Lucky for Tony Stark that the multiverse is much more imaginative than he is.

Part of the PWNY-verse.

Will freely mix several different Iron Man continuities based on what makes the story work best.

Crime was easy before Princess Twilight and the First Five ushered in a golden age of Harmony. Back then, any idiot could plan a robbery, just like any rat could sneak through the cracks in wooden granary walls. But now that everything is cloudstone and clearsteel, with magical countermeasures over the few remaining holes, it takes a different breed of rat to survive.

"Slippery" Jimmy the Grey is one of the rare few ponies who can still slip through the cracks — even with the legendary Rainbow Corps on his tail. Now he's got a billion-bit heist planned in the gleaming skyscrapers of Cloudsdale. If only he hadn't made the mistake of stealing from a dragon …

Now with a reading by Illya Leonov and Scribbler!

Twilight Sparkle is interrupted from a midnight study session by the arrival of three confused magic students.

A short Harry Potter/My Little Pony crossover. Can the universe handle Twilight Sparkle and Hermione Granger in the same room?

[Complete! With TVTropes apparently!]
Also, apparently, an animated trailer.

In a world of brass and steam, Twilight Sparkle had thought she had made a life-changing discovery with the invention of the telescope. For better or worse, she was correct.

Now her discovery has not only changed her life, but the lives of those she seeks out in her desperate attempt to contact the only other creature as lonely as Twilight herself.

It all would have been much simpler, but it had to be the one Twilight could only call The Mare on the Moon.

Decidedly not within walking distance, then.

This story is a sequel to Past Sins

Side-story to Past Sins - Slowly, the wounds inflicted by Nightmare Moon's reign heal. Ponyville is being reconstructed, and the last refugees are leaving the castle. Nyx is with Twilight. Celestia and Luna rule Equestria and guide the sun and moon once more. Everything is as it should be.

But some things are never washed away. These are the things that remain to remind us of the past. They remind us of the good times we've had with friends and family. They never let us forget the mistakes we've made. Everyone has them. Twilight has them. Nyx has them.

And, on occasion, when you share your scars, your photos, and your trinkets with another, they just might share theirs in return.
