[12/14/2014] Revisions to Chapter 4 and onwards. More info here: http://www.fimfiction.net/blog/416547/fixing-i-think-i-can-remember

Celestia is settling into being a princess. It’s a lot of work, but luckily Star Swirl is a big help, even if Luna isn’t.

Then she wakes up and over a thousand years have passed. Her sister was banished to the moon and came back, Star Swirl is long gone, and Celestia apparently has a small purple alicorn student.

What’s going on?

"It's going to be a long night..."

When a mansion appears out of nowhere in the outskirts of town, The Mane 6, are all invited to a housewarming by Specter Yield, the owner of the strange mansion. Hours after they leave to attend the party, the Cutie Mark Crusaders find themselves in this mansion. Eventually, Sweetie Belle finds herself alone in this massive mansion, trying to save her friends, and discovering the truth behind this haunted mansion. Will she be able to rescue her friends... and possibly all of Equestria from the ghostly presence?

Mis-communication has started many a war, but in this case maybe calling it a war was too generous.

The "war" is over, Twilight has successfully orchestrated a bloodless end to the Griffons' aggression, but only now does she realize that there is more to winning than she had first assumed, especially against a nation that holds war as a central part of their culture...

Now Twilight must deal with the aftermath while facing a challenge she never anticipated: being seen as a conqueror.

This can be read alone, but I recommend reading the letter that started it all for a chuckle and a little exposition. This series of expositional one-shots can also give some additional world-building.

In 2185, during his campaign against the Collectors, Commander Shepard discovered a previously unknown species whose origins predated any other race in the modern galaxy. Following a daring rescue from their ancient sanctuary, the Equestrian Herd was brought back into the galaxy where, for the first time in eons, they must walk their own path.

Knowing full well the terrible threat that lingers on the edge of the galaxy, the leader of this newly freed race fights to secure her people’s future while attempting to prepare for the storm on the horizon.

This is her story.

The long awaited Sequel to Mass Effect 2: The Equestrian Equation This is a reader directed story. Your choices will shape events.
If you favorite, also like! It's one little button click that makes all the difference.

Also, this series has its own TVTropes page now! (Special thanks to user CrowMagnon for setting it up).

This story is a sequel to Princess Celestia The Changeling Queen: Stories Behind the Mask

At the Royal Wedding, Chrysalis and the Changelings were revealed to all of Equestria.

But another mask was torn away that day. A mask born for a thousand years. A mask created on one promise. A mask, that has become synonymous, fused, to its bearer.

A mask that when ripped off, causes Twilight, her friends and Luna to question everything they ever knew about the one pony, one very important pony.

At the Royal Wedding, the meaning of the phrase 'Princess Celestia' changes forever.

NOTE: Chrysalis is NOT Celestia!!! That'd be impossible to pull off.

When Twilight tries a mass teleportation spell with her friends they get stuck in another universe. What's worse is that their landing point was a magical spring that curses it's victims to transform into whatever drowned there. They are now cursed to turn into human girls whenever splashed with cold water, but hot water changes them back.

They weren't the only ones to fall in that day. They meet Ranma a male traveling martial artist who fell into the same spring (meaning he turns in a girl), his father Genma who becomes a Panda. Twilight agrees to cure them when she figures out a cure while they give her and her friends a place to stay.

Due to a series of events, they wind up in Japan where they must pose as normal high school girls. Where they must deal with a stupid swordsman who falls in love with them, martial arts based on running, rhythmic gymnastics and figure skating, rivals from those sports. And that's barely scratching the surface of the insanity that lies for them...

Edit: Now a collaborative effort with Loyal2Luna

Commander Shepard has been through a lot, but now that the Reaper War's over he can finally relax and take a little R&R, right? Soak up the sun, grab a few drinks, spend some quality time with Tali, introduce a new race to the galaxy... wait, what?

In the aftermath of the war, a new species has been discovered amidst the destruction and fire. A species that have access to powers never seen before, powers which could prove vital to the continuation of galactic survival.

The Citadel Council has elected to send Shepard, along with the rest of the crew of the Normandy, to introduce Equestria to the universe outside of their solar system.

Now Shepard must wade through obstructive bureaucrats, antagonistic journalists, and the odd, angry prince in order to bring Equestria into a new age of space and adventure.

So settle in, it's going to be one hell of a vacation!

Now has it's own TvTropes page

[Featured on EQD 21/4/2014] [Now on TVTropes]

When Luna gifts Twilight the town of Ponyville and its surrounding countryside as her demesne she's initially confused. Then, after double checking her dictionary, more than a little concerned.

All her friends are, legally, her possessions. The town that took her in is her plaything, if she so wishes. She has been given responsibility.

Can Twilight's vision for a modern renaissance outrun the harsh realities of the shadowy figures pulling strings behind the scenes, nobles jockeying for her attention, and an irritatingly metaphorical love triangle?

Special thanks to the insatiable Blue_Paladin42, the incorrigible Maskedferret, the intuitive Southpaw and the indestructible newbiedoodle for all their hard work, past, present and future.

After the changelings' failed invasion of Canterlot, Twilight tries to soothe some of Ponyville's rampant paranoia by casting a spell to prove there are no imposters hiding in the town. But her spell leaves her in an alien body, facing a mob of angry ponies who just don't believe her when she says she is Twilight Sparkle.

Or, at least, she was Twilight Sparkle, anyway...
