Twilight Sparkle - magus, heroine and Princess - has learned of worlds overlapping Ungulatia in space and time. Though this has been a well known phenomenon, safely traveling to these other worlds has always eluded pony mages. But now - after years of research and careful experiments - she prepares herself for the most audacious of all experiments: stepping hoof on the surface of an alien world and returning safely! What wonders will she find once she walks through her magic portal?

This assumes that Equestria Girls never happened.

This story is a sequel to Voyage's End

Eleven years has passed since ponies and humans met for the first time. Now, Twilight ventures out on her most incredible endeavor to date.

"Once more, we boldly go into that great unknown." -Twilight Sparkle

In the land of Azeroth, the dragon aspects fought their former brother, Deathwing. The mortals failed them and they were unable to defeat him. In a desperate attempt to save their own world, they sent Deathwing to another world in hope that he would land somewhere unpopulated or simply die. Neltharion/Deathwing lands in Equestria, free from his own corruption he seeks to redeem himself and find his way home to his family.
Meanwhile Princess Celestia have a vision of Neltharion destroying Equestria and she sends Discord to find him before that happens.
Friendships will be made and be broken. Love will blossom and anger rekindled. But in the end, will Equestria survive? Or will it all be consumed in Fire?

Takes place after S4 finale but does not include S5 canon

World of warcraft crossover

There will be some shipping in this story and it will have somehwhat of an impact on the plot simply because I think it's too good of an opportunity to miss.

27/04/2015 UPDATE: All chapters have been corrected of most grammar related mistakes. Correction and editing was done by Exaxxion

This is my first fanfic, just so you know. Critique would be highly appreciated, since Im trying to get better at writing. Hope you enjoy the story.

Cover picture is by the amazing and talented Hussii. I have not asked permission to use his art as he, unfortunately, has been offline for over six months. If he by any chance stumbles across this fic and is not okay with me using his art, please message me and I will remove it.

Following his tumultuous defeat, King Sombra is flung across space and time to exit out a human's malfunctioning toaster. For weeks, Sombra monologues his revenge to destroy those that hurt him. But seven months later, when a route back to Equestria is found, does he not seem all that interested in returning.

Prequel: The Roommate From Tartarus
Side Sequel: (Not My) Home Sweet Home

Update: labelled as complete. The last three chapters will remain as bonus chapters.

King Sombra’s dark influence was obliterated by the Crystal Heart, and the villain is well and truly dead. But when he attempts to steal the afterlife of an innocent victim, a human spirit is left hurtling towards Equestria, where this unfortunate soul is revived into the only vessel available: the reconstituted body of King Sombra himself.

Thus, a cheerfully oblivious alien is crammed into the form of the most evil and malicious being Equestria has ever known. Not that Shining Armor and Cadence know this, of course. As far as they are concerned, the King is back and he’s lost his fricking mind.

This story is a sequel to Stardust

Times are changing for Equestria as Twilight’s return brings with it news of people and cultures from beyond the peaceful world everypony knows. Aid and volunteers are freely offered to help the besieged humans of Earth because every Equestrian knows that’s what good friends do. Unfortunately, making friends can also have the unintended consequence of making enemies.

When the monsters besieging the humans strike at Equestria with a level of brutality not seen in over a thousand years, the cry for help is sent to all the kingdoms of the world. Honored allies step forth to fulfill ancient treaties and oaths. Enemies, old and new, bury their grievances. An alliance never before seen in Equestria will be created to combat the monsters from the void.

And because of these events, a grim but welcome sibling to the XCOM project is born.

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."

Now with a Rage Review!

"OH! That would be the Elements of Harmony! They're the neatest thing! We each get a jewel necklace--Twilight gets a sparkly tiara--and we used them to defeat Discord and Nightmare Moon with rainbows that go pewpewpew-!"

A clawed glove wrapped over Pinkie Pie's lips, silencing her.

"What does the pink one speak of, pony?" He demanded of Twilight, who sputtered at his question. "Do these 'Elements' hold the power to resurrect humanity?"

"I'm... not sure." She returned, halfheartedly. "They're pretty powerful..."

"Where are they?"

"In Canterlot, the city on the mountains, but-"

He dropped Pinkie and stomped off, leaving her to flop around her stretched-out lips. Twilight saw that he was going out the door and in the direction of the city she had mentioned.

"W-wait! Stop!" She galloped after him.
