This story is a sequel to Sunset's Crowning Achievement

The last time Twilight saw Starlight Glimmer, she threatened to kill Rainbow Dash when she was just a filly and ruin Twilight's life by going back in time. Only, when she failed to find Starlight in the past and returned home, Equestria wasn't a ruined wasteland, Ponyville was a lot bigger than she remembered, and all these new ponies in the castle were talking about some big pony they call Empress.

Harry Potter, after a beating by Dudley and friends wishes he had somewhere safe to go, and starts crawling home. He ends up in Equestria. The young Cutie Mark Crusaders find him. A year later, a Hogwarts owl unleashes the CMC, Harry, and Equestria upon wizarding Britain! And adorable cute magic-wielding ponies upon the rest of the world.

Inspired by Dogger807’s hilarious story, “Magic School Days,” here on FiMfiction. While there is humour (and tree-sap) in this story, that is not its only focus.

Wow, Sir Chaos Omega made a TV-Tropes page for the story! Thanks!

Published on the FiMfiction website with the kind forbearance of the copyright owners of My Little Pony (Hasbro) and the Harry Potter series (Scholastic Press).

The timeline for “My Little Pony” is messed up. That is, if you look closely, the order of the shows as aired is out of order of their logical sequence. Evidence: in Swarm of the Century (#10) we see the dresses that Rarity makes in Suited for Success (#14) — so unless Rarity time-travelled, #14 should take place before #10! Also, in The Ticket Master (#3), the other five seem to know Twilight and Spike quite well, yet in Boast Busters (#6) they don’t seem to know Twilight at all.

With careful attention to details such as those, you can put the three years of episodes prior to Princess Twilight Sparkle (#65, Season Four) into a two-year stretch of time. If you work hard enough, you can even squeeze them down to one five-season stretch of Summer to Summer.

I used the two-year seven-part timeline mapped out by deviantart’s tobyandmavisforever (do a Google search for “tobyandmavisforever mlp timeline” as the fastest way to find them). Thus, Harry arrives in Equestria shortly after the Crystal Empire two-part episode, and Twilight and Spike have been in Ponyville just under a year even though the Crystal Empire episodes start the third year of My Little Pony.

“No, I didn't strap a rocket to you. I strapped you to a rocket.” /to Rainbow Dash
“Friends? Who needs friends?”

From one barren wasteland to another, less barren wasteland, an Australian Information Technology worker finds himself stuck in the snow with nowhere to go. Armed with nothing but a cheap tool set and a three metre Ethernet cable, he must find a way to survive his new location. At least it can't get any worse... right?

Oh of course it can, it's a HIE.

Warning: Contains Australian, Changelings (of course), snow, occasional IT speak, less-than-stellar HIE satire, and shoddy humour not fit for a backyard comedy club.

This story is a sequel to Oskar Osäker: Your Worst Enemy

[Prototype 2] X MLP:FiM crossover

Emerald Gleaner once thought the NYZ would remain in her memories and nightmares. But with the appearance of one Sunset Shimmer this terror of the past is brought back to the forefront as Emerald and loved ones dive unknowingly back into the darkness of Blackwatch's heritage.... and there is no running from your past when it is screaming it's fury in your face

A big thank you to More Dakka for the Coverart, Nightmare Knight for editing
(Fimfiction likes to chew up coverart when it's big, if you want to see how it's supposed to look, take a look at my user page.)

Everypony enjoys myths and ponytales, even if they know such things aren't real. Alicorns fighting against a spirit of chaos? An ancient princess trapped in a library under a tree, waiting to be found? Quite enchanting and fantastic tales yes, but nonetheless as fictional as Daring Do and other such stories. At least, that's what Rarity used to think.

She doesn't anymore.

Dedicated to Annuska for being as amazing a writer as she is a friend.

She was a unicorn on the run. Being hunted, her only option was to hide where they wouldn't think to look. Once over the border she'd hide in the most quiet, boring, unassuming town she could find in Equestria. Her information was out of date but how much could Ponyville have changed?

Once there all she'd have to do is keep her head down and not draw attention to herself. Certainly stay away from any adventure or authority figures, top of which being the Princesses. She'd shuddered to think what would happen if they found out who she really was. Still, what were the chances that she'd be dragged into an adventure or meeting any princesses while in Ponyville.

Thank you to 'Greynoise' and 'Starlight Nova' for editing and pre-reading respectively.

No idea who did cover art, let me know and I'll credit you.

A millennium ago, give or take, Princesses Celestia and Luna were nearly defeated by the most powerful villain that they had ever faced, Grogar, the dreaded lord of Tambelon. Thanks only to the whims of random chance, the two princesses survived that encounter, but have been forced to live in fear of the time of his inevitable return. That time is now...

...But whatever revival was intended has gone a little... wrong. Behind the wheels of Grogar's body is the spirit of a slightly extremely eccentric human. Equestria would have been lucky to survive the real Grogar, but will the ponies fare any better with this loon ruling Tambelon?

You. Have. Been. Warned.

After the Friendship Games, Sunset feels it's time to return home.

Only when she gets there, Twilight's castle is nowhere to be found, Cadance just got her horn, and Princess Celestia is still calling the bacon-haired pony her prized student rather than a failed one. And just reliving her past isn't on the table thanks to a pair of wings Sunset seems to have sprouted upon her return to Equestria.

With Sunset being back before she's supposed to, will the world stay as harmonious and on track, or will everything go down in flames as Sunset has to deal with allegations that she's really a changeling in disguise, a nerdy stallion with blue hair that wants to be her coltfriend, a pretty pink princess in need of remedial magic lessons, and an annoying purple pre-teen pony that will absolutely not go to bed without first being read Starswirl's Complete Mystical Mysteries Compendium?

Only time will tell
