With an age-old threat poised to devastate Equestria, the Princesses gather to use a spell left behind by the great Star Swirl the Bearded in order to ensure their victory.

Now all four have become an entirely new being, with her own thoughts and feelings. And in order for the Princesses to return, she will have to die.

Once upon a time there was a very lazy dragon who did not want to find a town to pillage.

So he decided to make one of his own.

A reboot of Waking Nightmares, taking the story in a different direction.

Celestia has been suffering from nightmares and her sister Luna cannot seem to stop them. Alongside this, the dreaded Queen Chrysalis has been caught and is finally standing trial, several world leaders attending to help decide her fate. On top of all this, nine ponies and a dragon have appeared, claiming to have been transformed and sent to Equestria by an insane wizard.

What else can go wrong?

Smaug is the mightiest of all beasts in Middle Earth. No creature can match his prowess. As the last of his kind, he has no obligations to anyone being other than himself. The only thing he cares about is his hoard.

But this new creature, this alicorn, may just change that.

Just for Harmony and the Sisters, Discord decided to take things a bit seriously the second time around.

Now seemingly unopposable on his Chaos Throne, King Discord has all of Equestria at his clawtips.

His very first decree? The very first royal act of chaos? The moment that may define his reign?

Pardoning Mane Six.

Wait, what?

Discord's reign will be filled with surprises, chief being how the draconequus is far from malevolent to those in his lands, despite what the ponies have been told. It seems that while Equestria belongs to Discord now, but he does play(mostly) responsibly.

And as time goes on, the appeal of Chaos can worm its way into most any heart.

NOTE: Not a tyrantlestia fic.

This story is a sequel to Why No One Messes With Celestia

In the wake of Celestia's return to Equus, the ponies have worked tirelessly to prepare for the arrival of the Ascended. Defenses have been set up, weapons prepared, allies warned, but most important of all in the minds of both Diarchs, a cure for the Indoctrination has been pursued.

The Ascended, or the Reapers as they are known to the rest of the galaxy, are not amused. They attack in force, unwilling to stand by and let this small, barely space-worthy race of unascended quadrupeds neutralize their most effective weapon in their march towards galactic cleansing.

Now they too shall learn to fear the dark, and the Princess who controls it.

This story is a sequel to Why No One Messes With Luna

Shepard has done the impossible. Old foes have set aside their differences, new friends have come into the fold, and the galaxy is more united than ever before. But the Reapers care not for the new alliances they face; they will fall, as countless civilizations before them fell. It is inevitable.

There is still hope. The Crucible, source of unimaginable power, has been constructed by the allies. With this new source of hope in tow, the allied fleets break through the Earth blockade and attempt to use this newfound weapon in a last, desperate attempt to defeat the Reapers and save the galaxy as we know it. Fleets of all races, soldiers of every kind, are united in this final stand.

Equestria, too, has sent what they can to aid in this final battle. Or rather, who, they can.

The Reapers have no idea what they have unleashed.

Warning: This story contains spoilers for ME3 and takes place during the ending of the series. This story is less approachable than the previous stories and may be confusing to those who are unfamiliar with the ME3 ending

Ponies have spread to the stars thanks to advances in technology. In the advanced and luxurious Solar Explorer, Celestia travels to the first extra-solar colony world set up by her little ponies. Unfortunately, events elsewhere in the galaxy, unknown to them, have set in motion a cycle that has been repeated for countless eons… the reaping of sentient races. A Reaper dreadnought confronts the Solar Explorer, intent upon indoctrinating the leadership of the ponies and bringing them to heel.

Said Reaper quickly learns exactly why Celestia has earned the title Unconquered.

A Mass Effect crossover oneshot.

Now with a reading done by Scarlett Blade! Check it out!

All of Equestria is united in celebration for the return of their beloved Princess Nightmare Moon. But when Celestia and everypony else recieve her she's skeletally starved, filthy, and very nearly dead.

(Alternate Universe, there never was a Princess Luna)

Two thousand years after the return of Princess Luna, Equestria's technology and magic has advanced far enough that the once far off dream of faster than light travel is now a reality.

And that reality is the ES Harmony, the pride of its designer, Princess Twilight Sparkle, and Equestria's first FTL capable starship. It is due to make its maiden voyage to travel further than anypony before it.

And yet when they receive a distress call from origins unknown, this ship's maiden voyage will become one the crew will never forget.
