Dusk Shine is Twilight Sparkle's twin brother. They have a lot of things in common, love of magic, love of books, neurosis, but they also have some key differences, and not just what's between their hindlegs.

For my first new story in three years (not that I was updating the other ones) I want to try something a bit simple but with loads of possibilities. While I will be following the order of episodes of the show and going through most, if not all, of them, I promise they will be trans-formative and not simple retrots of the episodes with another purple horse hanging around.

I've often heard it said that Equestria would not survive with two Twilights running around. That just may be the case.

A teenage Twilight Sparkle asks Princess Celestia a complicated question with a simple answer.

This story is a sequel to Tactics of Snowbound Unicorns

Harmonic bonds aren't the most predictable of spells. Sunset learned this the hard way with Twilight. Involving Moon Dancer will make things either extremely complicated, or extremely simple.

And that has nothing to do with harmonic bonds.

Knowledge of the previous stories set in the Wavelengths Timeline is suggested, but not required.

Twilight Sparkle is a truly terrible dancer. Everypony knew this, even Rainbow Dash. But, after accidentally blurting out a request, Rainbow decided she'd seize the opportunity, no matter what other ponies may think.

Written for my girlfriend, who's probably a better dancer than me, though that's setting the bar pretty darn low.

What's one of the more embarrassing things you could ever have happen to you? Getting a wingboner in front of all your friends seems pretty high on the list. Twilight is of course grateful for her wings, but they do have their downsides. Lucky for her, a good friend won't mind comforting you even under such awkward circumstances.

Rated T for: Sexual themes

Holy shit, I didn't expect it'd be a popular story at all. Thanks you guys. <3

There's nothing strange about Alias, except for how awesome and radical she is, and how she totally relates to all today's youths and is not Queen Chrysalis. In fact, she's so definitely not Queen Chrysalis it's bodacious and by the way, what's your greatest weakness?

A regular customer can be very much like a friend, and so Rarity is always willing to go the extra gallop in order to keep one of her true favorites happy. Exotic fabrics, special gems -- if she can meet the request, she will.

Now, when it comes to the newest item she's been asked to create... what exactly is it, and how is it supposed to work?

(Now with author Patreon and Ko-Fi pages.)

Bored due to there being nothing for her to do, as no Friendship Problems have arisen that have needed her help, Twilight decides to visit her Canterlot High friends and see what's going on.

However, something goes wrong and the portal closes, leaving Twilight stuck on the other side. That's fine though. She can just hang out with her friends and wait it out.

However, it won't be that simple. Though she turned into a human like normal when she arrived, Twilight is now about 6 to 7-years-old and it seems she has access to her magic as if she were still an Alicorn. The human world isn't prepared for this.

AU universe where Friendship Games happened before the Season 5 finale, so Twilight's human self is already transferred into CHS, but pony Twilight has yet to go with Fluttershy on their Friendship Mission.

Rated Everyone for now, but may change it to teen depending on future chapters

Note: Twilight didn't see Sunset's messages in this AU due to them coming whilst she and the girls being away dealing with Starlight, followed by how much she'd been avoiding her castle in the following episode.

Spike is the reason the messages never got answered though, due to Big Mac accidentally knocking the book of it's place on the machine whilst he and Spike were in the library, Spike not being there in time to see it glowing to indicate messages being received, so he just placed it back on there without a thought.

Whoa. Featured 3-4/3/2017. Okay, honestly, I really did not see that coming. What?

Her brilliant plan was ready to put into motion. All she had to do was get to the right place, then wait. How hard could that be? It wasn't like Twilight had any security measures of any kind.

IMPORTANT: THE STORY HAS BEEN CANCELED DUE TO ME AND Julunis14 HAVING A FALLING OUT I'M REALLY SORRY.

After the leaders of Equestria were kidnaped the Canterlot Nobility were enraged. They now are demanding the subjugation of the changelings, whether peacefully or by force. In a desperate attempt to keep the peace Celestia must make a difficult decision. A decision that will change the life of her former student forever.
