This story is a sequel to Fecundity

Mount Everhoof. Tallest peak in the world, jutting up to stab the sky like a tall, cruel fang. The mountain’s western slope has held a secret since before the three tribes were founded, but few who seek it ever return. Those that do always speak of a foul magic that attacks the mind—horrors brought to life, paranoia unending, and a blind, murderous rage that sets even family against each other.

In olden times, Princess Celestia and Princess Luna heeded their elders and forbade access to the western slope. That forbiddance continued after the rise of Nightmare Moon, for Celestia realized even alicorns can go mad. The last ones allowed passage were a team of ponies sent by Princess Cadance and Prince Shining Armor two years ago, and of the seven that set out… only one came back.

But the mystery may be on the verge of being solved. The defeat of Tirek has awakened a new power in the Elements of Harmony, one that can resist Mount Everhoof’s empathic magics. With the aid of Maud Pie’s expertise in geomancy, Twilight Sparkle and her friends now venture up Mount Everhoof in search of an artifact belonging to the late King Sombra. They’ve yet to learn what connections the Mad King had with the mountain, but they know they must locate the cursed artifact and destroy it…

...before it can cause any more harm.

Celestia has never used her full power.

Ever.

But that might be about to change. Chrysalis has contacted her and requested a meeting out in the middle of nowhere. Celestia expects a trap. In fact, she's hoping for it.

This is a short little Silvellus story (Ocellus x Silverstream). I really love these two together and this was kinda just a random idea I had... It involves a headcanon I have about Changelings I suppose. Should be pretty easy to understand though.
Ocellus suddenly begins to hiss randomly at lunch, confusing her greatly. Since it's Spring break, she decides to ask King Thorax is he knows about what's going on.

The background changeling's name I used, "Lemony" is credited to DA user sketchmcreations. I think we should start giving background creatures names too...along with other new background ponies.

The ending of this is probably rushed and crappy, but it's sort of supposed to be left up in the air I guess. I've had writers block lately too, but I think this turned out ok. I really ship these two, haha.

Life had just settled down for Sunset and Twilight Shimmer. A child on the way, major choices to make, classes to choose for spring.

And then Celestia appoints her as her temporary replacement while she and Luna step down for a time. In the wake of this are whispers, riots, and mysterious slogans bearing a single word:

Entropy.

Continuity: Homecoming

An interlude between Flammenwerfer's fics Metroid: Equis and its sequel, Metroid Equis II: Duality.

The war is over. Equis has survived the dual threats of Phazon and Space Pirate invasion. A new era of peace and prosperity covers the planet, as new trade routes between Equis and the Federation - centered in the country of Equestria - bring new technology and wealth to the nation, and the world.

But these thoughts are far from Fluttershy's mind. Her thoughts are focused on her friends - especially Samus, far distant from the world - her daily life, and her animals.

In particular, a new one... One she's never seen before. But she calls Fluttershy Mama, so of course she'll care for the little flying jellyfish, whatever she is.

What could go wrong?

Edit: It isn't required to read Metroid: Equis to enjoy this story...but it's highly recommended to read it anyway. It's a really good story.

This story is a sequel to Metroid Equis

With the culmination of events on the BSL Research Station, Samus Aran is finally able to come back to Equestria, Planet Equis; to come back home. Much has changed in her absence, but it is still the friendly, peaceful, welcoming planet and nation that she left behind two and a half years prior. With the Space Pirate threat neutralized and the secret, illegal Metroid militarization programs destroyed, it appears that Samus can finally take another massive breather with her friends and enjoy some well-deserved rest, recovery, and relaxation. The galaxy is finally at peace.

At least... for a short while.

A new enemy, one much closer to home, soon rears its head, threatening all of Equestria and Equis with complete and utter annihilation. Their mission: revenge. Samus will fight with all of her being alongside her allies against an enemy who would like nothing more than to see all that she holds dear, including her home planet, completely razed. In so doing, her cunning, ever determined enemies unleash a weapon so unexpected, so eerily familiar yet horrifically foreign that even Samus herself just might prefer the late Ridley or the SA-X...
