It is the year 2038, and the Earth is slowly being consumed by a space-borne monstrosity dubbed the Black Tide, which is using nanotechnology to remake the planet into something hideously alien.

Erin Olsen works for Project Harmonics, humanity's last-ditch effort to find a new world before the Tide can wipe them out. But when that world is found, and it turns out to be occupied, Erin will need to find the courage to face the unknown in order to save the inhabitants of both worlds.

There is now a follow-up to this story: Sunflower - Side Projects
Sequel: Project Sunflower: Harmony

She’s the loyalest of friends and most dependable of ponies; how could anypony not fall in love with Applejack? In fact, so much of the town has found themselves under her seductive spell, they’ve formed a secret society to help each other cope with their unbridled lust. Operating in seclusion, this group has been an unseen staple of Ponyville. Surely, though, nothing good can come of the mare herself discovering the existence of Applejack Anonymous.

Princess Luna is bored.

She spent a 1000 years on the moon and while she is happy to be back to her old self (even if she knows her evil scheme would have worked if it weren't for those meddling mares!) her sister refuses to let her do anything fun. .

The Princess of the Moon is fed up! She is going to go on an adventure! She is going to find Queen Chrysalis and punch that bug in the flank! And along the way she is going to fight bears, fall in love, explore strange worlds and everything else all the guide books say should happen on an adventure.

Too bad her sister (The ever calm and collected Celestia) has decided to tag along and bring their niece (the sex-crazed Cadence), nephew-in-law (the sane and rational Shining Armor) and brother (the grumpy OC/Oceanic Creature Tydal) along for the ride.

What happens when the gods go on a road trip? Chaos, insanity, and mayhem, of course!

(This is the spiritual sequel to "The Many Secret Origins of Scootaloo". While you don't need to read that story to enjoy this one, it wouldn't hurt to give it a glance to understand why many of the characters are the way they are).

The sequel, The God Squad: Equestria's Most Wanted, will be out soon.

Twilight isn't having a very good day. An experimental spell blew up in her face, an army of changelings is attacking Canterlot, and she just died. Yet somehow, it looks like it's going to keep going downhill from here.

Given the chance to correct what's gone wrong, Twilight swears she's going to fix all this even if it kills her. Which it will. Frequently.

Twilight Sparkle presents a collection of interviews, letters, essays, poetry and prose compiled over several years of her relationship with the human Bellerophon and his "herd", covering subjects as broad as Equestrian social taboos, comparisons of earth and Equestrian mythology, romance and the occasional recipe. Compiled by Twilight Sparkle, with foreword by Her Royal Highness, Princess Celestia.

(This is a bit of an experiment based on the worldbuilding concepts presented in AnonAuthor's Xenophilia [[NSFW] - caveat lector!], which intrigued me enough to want to take a closer look. It's likely you'll be very confused by this unless you read at least some of Xenophilia. Updates will appear as and when an idea pops into my head for a thing to add. And fair warning, some of this might come across very dry and dusty. Thank you academia! And thank you AnonAuthor for letting me have a go, and both AnonAuthor and AnonponyDASHIE for all the collab work they're doing. I'll make up for the dust by tossing in the odd piece of art now and then.)

No pony is the same after witnessing a work-related death, no matter who they are. The victim was young, eager, fresh-faced, and recently hired. In his last breaths, he let out a scream so heart-rending that the employees who heard it had difficulty sleeping that night. And Rainbow Dash was no exception.

But she's not losing sleep over that. What disturbs her is something far worse—something she said afterwards.

You'd think that being trapped in stone would mean that, if nothing else, I could get some peace and quiet. Unfortunately, it seems that Celestia has other ideas.

She has appointed these ponies... these 'Keepers', as she calls them, to keep me entertained during my incarceration.

Honestly? I'd prefer the boredom.

What started as a normal friendly visit ends up taking two ponies on a trip down memory lane that leads them both to realize their friendship began even before Rainbow Dash's first sonic rainboom.

I have always been alone in this forest. I have always feasted in this forest. I call this forest home and those ponies that travel through it are my prey. I devour all those who fear me, all who come to face me. They fear me for I am Fear incarnate. But now...I have met one who does not fear...and I am unsure of what do with her...

All of Equestria is united in celebration for the return of their beloved Princess Nightmare Moon. But when Celestia and everypony else recieve her she's skeletally starved, filthy, and very nearly dead. Meanwhile, while everypony's eye is turned, a lusty Blueblood pursues Twilight Sparkle, intent on adding her bloodline to his own so his family might step closer to godhood. (Alternate Universe, there never was a Princess Luna)
