The mane six are just doing what they normally do, when they hear about a letter from Princess Celestia. They get ready for the upcoming danger, not expecting what's going to happen next. When they reach the castle, they see a horrible sight not anypony wants to see.

After reading Rainbow Factory Condemned, by LordCarn, I felt that the ending wasn't sufficient enough, so here is my extra bit that I felt was needed to do the ending some justice.

This is ultimately my own creation, although it picks of where RFC left off and is a much happier ending than the original. I do not intend to carry this on in second person as it would ruin the whole perspective of the story.

So I give to you, the people of FIMFiction, my ending to Rainbow Factory Condemned by LordCarn.

In the Equestrian ponydom, fire of friendship insn't the only thing which can burn forever. And even if some fires aren't eternals, blazes always destroy much more that just pieces of land.

Two foreign ponies fight off various dangers to protect the peace and tranquillity of Equestria. Unknown to them, an even darker force is trying to destroy everything they love and know. Their new friends in Ponyville have no idea about their double life or what they really are. The pair's smarts and skills are the only things keeping Equestria from being corrupted by evil.

Currently on hold, but if you enjoy it, please leave a comment...if enough people bug me, I may continue it. For now, on Hiatus.

Mostly a first-person-view of a story about a human who'd since lost her memories of her first appearance into Equestria, the tale itself is mostly recollections and memories presented by the ponies she's met and talked with. There is to be more in the adventure category later, but that's when the story comes around to it.
This does involve the Mane Six to an extent, not to mention a fair share of OC ponies or simply original pony ideas created on a whim.

Nick is a inter-dimensional traveler- and has been searching for a long time to find the artifacts that will allow him to defeat the final foe- The Devourer, and this universe is the most promising of all. However, he needs to gain the trust of the inhabitants first.

Duel Monsters. This popular game in Equestria introduced by Discord had been the way ponies settled disputes for over a year. Little did anypony know, it was a trap devised by Discord. He brought these things called "humans" into our society a year ago, and now we're all but finished. These creatures of strange power knew more about duel monsters than any of us could imagine. Now, we're just barely surviving the onslaught of humans that keep coming. They also brought this thing called the Shadow Realm. This was what has diminished us. Even the four princesses couldn't win. This is about me, Diz, who came to be the last hope of pony kind.

Rated T for mild cursing

This will ultimately be related to some other stories I want to write at some point (i.e. they will be part of the same continuity), but this one is just a quickie on its own. The main (but not only) reason I wrote it was to vent a bit of my hatred for Discord. (Don't ask.) So yeah, warning for any Discord fans out there: you probably don't want to read this.

I'm not really sure if it should be given the dark tag or not. I personally don't think so, as there is no death, gore, or serious trauma here, but I'd understand why others might think it's a bit dark despite that. So I'll add it if enough people seem to think it deserves it.

Again, this is largely a venting story, although hopefully you'll still enjoy it. Just don't expect it to be all that wonderful.

Note: the mane 6 are in their early 40's and have kids that are teenagers. I don't own the picture I found it on Bing so all credit of the picture goes to whoever made it

The mane 6 enjoyed their lives until Discord came but thankfully it was temporary. But since then they been acting weird.
What happened while Discord was free? What will happen to the children? But most importantly what will happen to the mane 6?

It's not easy being the sidekick of a pony Demi-god, especially when your the town pariah...but Dipper is willing to do anything for the love of his life...so it all works out...hopefully...well, probably not... Dipper/Twilight, Wendy/Tyrone, Alchor/Pacifca
