Meteorite is a self-insert whose story began in 2011. However her story was never finished, leaving her to her own efforts to cope with the new but familiar world she found herself in.

Years later, her author thought it'd be nice to get back in touch with her creation, maybe do something nice for her, but things start to go off-script when the author is seen by somepony other than Meteorite...

Disclaimer: Australian (hence the profanity tag and 'U's in words, like 'colour')

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.

Equestria is safe once again, and Twilight has found her destiny. Still, the beginning of this new chapter in her life comes at a high cost, and Twilight must come to terms with the bittersweet ending to her latest adventure.

Twilight Sparkle became an alicorn by creating new magic.

Now, Twilight Sparkle has created new magic to turn other ponies into alicorns.

But only for one day.

What would your favorite little ponies do if they could be princesses for a day?

Let's find out...

A young human girl runs away from home with her best friend, and finds herself much further from home than she ever expected. Her arrival in Equestria will cause ripples that affect ponies from the lowest to the highest.

Meanwhile, a young Nocturne mare begins an epic quest to earn the right to clean Princess Luna's porcelain throne.

Let me extend thanks to Georg for letting me play with some of his characters and situations, and for proof reading and contributing some really good lines here and there.

Secondly, I would recomend reading some of his stories to better understand the jokes and situations that pop up in my story. Most especially I would advise you read A War of Words - The Opening of the Guard and possibly Genealogy (or the mating habits of Nocturnes Pegasi) (which is very long)

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."

Spanish translation by Spaniard Kiwi

Celestia and Luna were born as unassuming foals in troubled times. But already marked for greatness, the simple earth ponies stand to face a world set against them, full of danger, fear, and sadness. A world they will change forever.

A sweeping epic taking place before Equestria was made, where Celestia and Luna must rise from normal foals to become the Princesses we know them as, beset from all sides by monsters, other ponies, and even the forces that govern nature. Their tale is as tragic as it is triumphant.

Currently on hiatus. For more info, go here.

Sir John Falstaff had finally found himself in a spot he couldn't worm his way out of.

Now that Prince Hal has finally become King Henry V, he is purging the waywardness of his youth, starting with the rowdy friends he once knew. Some thrown in jail, some kicked out onto the street, all lost without a place in the world they once knew.

Their "daring" (sort of) escape leads them through a strange enchanted forest, where Falstaff and his band of travelers find themselves in a wondrous strange land, filled with magical talking horses. The former bandits seek refuge here, while trying to reconcile their decidedly un-pony-like natures with the social norms of their new hosts.

But interdimensional portals don't just randomly open on their own. And someone else from their old world has arrived too...

Update: Now with editing and contributions from a published novelist who worked as a professional editor for two decades (and also happens to be my dad).

Book one of the De Raptura Chronicles

Ditzy "Derpy" Doo, once a humble mail mare, was elevated to godhood in a last, desperate act by Celestia moments before she and the entire royal family disappeared. Now the newly crowned Princess De Raptura must contend with the machinations of a court completely alien to her, reconcile with her daughter, make peace with Twilight Sparkle and learn how to control the sun.

And she's fairly sure she still has a package to deliver.

The story continues in To See The Light

"This story differentiates itself from other 'bad things happen to Equestria' stories with its smart character work and realistic, powerful emotion. We need more stories like this." -Pre-reader who likes sky pirates
