This story is a sequel to Stardust

Twilight has finally returned home from the harrowing challenge that Discord set upon her, and the residents of Ponyville and the Elements especially look forward to having their dear friend returned to them.

Twilight, however, has changed. Still suffering from her injuries, almost incapable of using magic and haunted by the memories of her time on Earth, she becomes increasingly withdrawn from those who were closest to her. Will her frustration at her current state and her friends inability to understand her experiences cost her what she valued most before Discord's bet?

(Sequel to Stardust, familiarity with this is recommended!)
(Proofread by Arzoo!)
(Coverart commission drawn by the amazing KairaAnix!)
(Crossover with XCOM: Enemy Within, though the crossover and human elements are minimal)
(Featured 4/28/2014, thanks folks!)

Isolated from her friends and taken prisoner in the middle of a war, Twilight must deal with the very real dangers of being percieved as an enemy as well as the nightmares of her arrival on 'Earth'. Can she overcome her own fears and the fears of her captors? Will the wayward unicorn's assistance be a boon or a curse to the 'humans?' Most importantly, will she ever find her way home?

"In short, it's a story of friendship and plasma rifles, with the emphasis on the friendship. The characters are well written, the XCOM setting is fleshed out very well, and the story is compelling. If you love XCOM, you'll love the story, but even if you've never heard of it, it's more than worth giving the first 3 chapters a read.

There's excellent action later on, but the real strength lies in the collision between the friendly and naive world of Twilight Sparkle and the desperate world of humans fighting a losing war for survival and willing to do anything to turn the tide."

Twilight one night found a crying pink blob, and she could swear it was a changeling...but changelings aren't pink blobs...so she takes the creature in.

Featured: 11/30/2015! (For like ten minutes XD)

MLP/Undertale crossover.
Not a PWNY-verse story.

Long ago, the Monsters and Humans fought a great war. The Monsters lost, and were sealed in the Underground. It would take the power of seven human souls to break the barrier that kept them imprisoned. They only had six. And so the Monsters waited and hoped, praying that another human would find their way to the Underground. Some thought the seventh soul would give their King the strength to break the barrier. Some dreamed of a human who would be their friend, and save them all...or had nightmares of one who would bring back the war.

...but nobody came.

...but somepony did.

Eons after the war, with no way to tell how much time had passed above, a tiny blue filly with wings and horn fell into the underground, calling for her Mama. None knew the poor creature's nature or origins...but her soul was powerful with magic, even more so than a human soul.

None can know what will come...of this little 'Woona'.

Legends spoke of a beast with the most wicked desire to find a blacksmith. He was muscular, handsome, filled to the brim with testosterone. Whenever the sun sets, everyone hides in their houses, locking and barricading all the doors in desperate hopes that it will stop him. He prowls the night, seeking out the blacksmith, murdering the faces of anyone who got in his way.

His name, is Markiplier.

Now this beast comes to Equestria, his burning desire to find the blacksmith still with him. It's just too bad nopony saw this coming.

Edit: There will be no sequel. Have a pleasant day.

After meeting a bizarre colt in the ruins of an old castle, Rainbow Dash is thrust into the desolate land of Lordran. Trying to find a way back home, or at least to Equestria, join Rainbow on her quest across this land, as she finds out just how badly things are becoming here. A little brashness and a little more coolness might just be what this world needs.
Note: This is a side story to Sunset Shimmer and the Land of Pokémon. To fully understand this story's setup, and the previous paragraph, please read that one first. Or at least the first two 'paralogues' inside of that story. A general knowledge of Dark Souls 1 doesn't hurt either.
Contains: Use of crass language, death, violence, Dark Souls sh*t in general, and unhealthy amounts of awesomeness and coolness. Oh yeah, and this story is using the EQG Rainbow Dash, not the pony one.

After a mishap with the ghost portal, Danny Fenton finds himself stuck in the strange world of Equestria. The worst part? He's got enemies here, too.

Part 2 onwards will be written with the help of MissytheAngle!

Part 1 going through re-edits by Curify. This dude is awesome, I seriously can't say enough about his greatness as both an editor and a friend. Thanks, man.

Weeks after the failed assault on Canterlot by the Chrysalis Hive, things are tense in Equestria. A lone changeling looking for somepony to feed on is discovered in Ponyville like many often are. But that's where his involvement in Equestria ends, for his adventure in Skyrim is about to start.

Sent to a new and frigid land where people can be as cold and unforgiving as the weather, this changeling will find that all is not well; a civil war threatens to tear its people apart, dark forces work in the shadows to gather followers and waiting for the opportune chance to strike, and an ancient prophecy is about to be realized, as Alduin the World Eater returns to raise an army of his dragon kin to destroy all of Nirn.

But all is not lost, as the Dovahkiin, dragonborn hero of legend, is on a journey to fulfill her destiny, and save the world from Alduin's wrath.

Who better for out changeling to join up with.

Read on as their tale unfolds.

A long needed rewrite/ revision of my first attempt at a story, A Changeling's visit to Skyrim.
9/15/17: Changed title from the way too lengthy original "Escapades of a Changeling Soulstoke: Skyrim".

Sunset Shimmer is just an average, everyday unicorn-turned-magical-girl who fights off the occasional arcane threat to her local high school, that hails from her old home dimension. After the recent mishap of the Friendship Games, Sunset knows she has found true magic in the form of six great friends and a talking dog. With this magic, she knows she can handle any situation that can come her way.
Unfortunately, waking up in a strange city with a stranger animal on her head doesn't quite qualify as something she's prepared for.
