Shawn Spencer, psychic detective, is a thick-tufted boy genius who ice skates through life on polished blades of snarky eloquence. He has tested himself against some of the greatest criminal minds of his time and emerged victorious... though often through unbelievable luck and not a small amount of bumbling.

Now, he faces a challenge unlike any before. One that will test his mind, his sanity, and his adaptability as he is thrust into the midst of an unfamiliar world and the ponies who populate it.

The Mane 6 face their own challenge, as an old enemy, tempered in the crimes of a much harsher world than theirs, returns to Equestria. It is a challenge they are ill-prepared for and one that only their strange, new, alien friend can help them overcome.

There are a thousand reasons for not making a purchase at the Carousel Boutique. Some of them are legitimate. Many are excuses. The majority are lies. Falsehoods which Rarity has been listening to for years now, without the slightest touch of variety in the performances. Lies which, during the first week of Ponyville's summer tourist season. have escalated to the point where it feels like they're the only words being said at all.

So if nopony is going to buy anything no matter what Rarity does -- why not call them out on a few? Surely that couldn't do any harm, at least not more than what's already been done?

Surely...

This story is a sequel to Past Sins

Hearth's Warming is a time for friends and family to come together, celebrate harmony, and welcome the new year. Nyx is looking forward to just this as she rides the train to Canterlot with Spike and Twilight. She's going to meet her extended family for the first time and wants nothing more than to make a good impression. Yet, the sheen of the holidays can't hide the trouble caused by meddling grandparents, relentless reporters, and a paranoid uncle.

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.

Twilight Sparkle broke time when she got her cutie mark. Now Twilight and Sparkle are sisters from another time. Twilight is hailed as the potentially greatest light magician of all time, and already has a reputation as a hero by the time she goes to Ponyville. This isn't her story, not primarily.

Sparkle is an orphan - her dark magic killed her parents. She lives with her brother in Canterlot's industrial sector because they can't afford anything better. She can't leave either. She's a natural dark mage; while Sparkle won't go mad like Sombra, her reputation is hardly any better. Worse, the law doesn't see her as a good pony.

The fact that the dead don't stay dead around her, or that Thorn - Spike's double - is an undead, soul-eating abomination, are other matters altogether.

(Also has some Slice-of-Life, but fimfiction tags won't let me put it with Adventure.)

Has an ask blog to go with it: Ask Sparkle and Thorn.

Rainbow Dash has an unusual way of learning, and Twilight’s determined to take advantage of it. Before she knows it, Rainbow’s worst fears become reality and her life unravels before her eyes as she becomes the smartest pony alive.

The dark tag is for the implications of the story.

An entry for the April 2015 write-off event, with the prompt “Great Expectations.”

This story is a sequel to Twilight Sparkle Exports Herself Repeatedly

After a drastic and ill-advised attempt to quash news stories regarding her previously non-existent love life, Twilight Sparkle has inadvertently given practically everypony she knows the wrong idea about herself. Or is it the right idea? She really doesn't know.

Which is starting to become a very serious problem.

The writer has no idea what he's doing at this point.

While doing some cleaning in the library's basement, Twilight comes across an old, long forgotten board game. Deciding that it looks like fun, she invites her friends over for the night to give it a try. Unfortunately, this particular game might prove to be more of a challenge to the Elements of Harmony than anything they've faced before. For you see, in Diplomacy, the number one rule is: Never play this game with friends, or you may need to find new friends...

This has a sister-story named Games Ponies Shouldn't Play, which features the Lunaverse six instead. It isn't going to be the same story with swapped names; each group has different personalities so both games will be very different. I just couldn't decide which group of six would be more interesting, so I wrote both. I must hate free time...

And featured 1/29/15.... ten minutes after I updated with a new chapter....... Why don't I update this story very often again? Gonna have to fix that...

This story is a sequel to Culling of the Hives

It's been twelve years since Twilight awakened as a changeling. With Phoenix Roost's focus on economic and population growth, the hive has grown strong.

The rest of the changeling hives have been ravaged by war for years with Twilight's brood remaining aloof. Sphinx psyker immigrants have dispersed throughout not only Equestria but as far as the Griffin and Minotaur nations, eager for a new life away from the paranoia of their homeland.

Yet for all of Twilight's desire for leave the rest of the queens to their wars, the Home Guard's proclamation will force Twilight to return to the jungle of her rebirth.

Real cover art pending.
