Blue words link to the character voices how I imagine they sound. Feel free to ignore them and have your own interpretation.

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

Twilight and her five friends are transported during a botched spell, across dimensions to... Ponyville, Equestria? But not the same one that they knew. Sitting on a bench is Harpsy and Babar. The Doctoress avoids apples from an aspiring Applebuck. And in a library across town, six stallions join their forces as they try to decipher the appearance of filly look-alikes of themselves around Ponyville!

The Equestrian Industrial Revolution is in full swing. Rainbow Dash returns to a drastically changed Ponyville and to Twilight Sparkle, her last friend in the city. She must rekindle the bonds of love and friendship before the winds of change render the Elements of Harmony irrelevant. Even in a world of steel, fire and glass, loyalty is needed more than ever.

Vaati the Wind Mage has grown bored with the whole villain thing. He's trapped himself in a cycle doomed to repeat itself forever. Seeking a way to escape this miserable cycle of escape, kidnapping, and defeat, the legendary sorcerer inadvertantly teleports himself to another world entirely; a world populated by talking magical ponies who believe friendship is magic. Just how will the former villain survive this sugar bowl of a world? Will he end up learning a few lessons in friendship himself? One thing's for sure, retirement has never been this exciting.

AUTHOR NOTE: This story takes place in an episodic format. That is, it follows the style of the show in that every chapter is an 'episode', hence why they will all be lengthy. Some episodes will be canon ones with Vaati along for the ride, and others will be original where Vaati takes center-stage. The first episode takes place shortly after 'Griffon the Brush-Off'. Vaati is from Legend of Zelda and is property of Nintendo. You already know who owns FiM.

Discord had one last trick up his sleeve to play before being locked up again: he's turned Equestria's timeless protector into its most dangerous threat. The kindhearted princess that ponies loved and adored is gone, replaced by an alicorn of iron and blood that forged Equestria out of the fires of pre-history.

Can Twilight Sparkle survive being the student of a pony who never had need of the magic of friendship or will she be forced to sit on the sidelines as Equestria irrevocably changes around her?

Twilight Sparkle. A name known to everypony in all of Equestria. She's saved Equestria multiple times now, and with her and her friends being the Elements of Harmony, as well as being Princess Celestia's "Most Faithful Student", she enjoys a great life.
But what was before that? Follow her on her journey through foalhood, and her times as Celestia's Student.

Chris and Keon are two zoology majors that get separated from their class after following what Chris believed to be an undiscovered species of bird, during a trip into the Amazon rainforest.

Finding themselves stuck in a pit, they discover an ancient ruin adorned with murals and statues of what they believed to be ponies. They soon realize that the bird in question was the orchestrator of their fate, as they’re brought to what they are certain is their deaths.

Waking up, they are not only separated from each other, but in a new land entirely. Will they take this opportunity to learn about creatures only ever seen in legend, or will they be too busy being studied themselves?

Humanity has grown to control most of the Sol system, and looks to distant stars for further expansion options. When probes discover an uncannily-earthlike planet at a vast distance, the Solar Government takes on a project larger than any before it.

A colony ship, carrying over seven thousand people, the Eclipse is constructed. Thanks to its translight engine, it is capable of making the journey within two decades. The expedition is launched with high hopes, its crew made up of the best and brightest, setting out to prove that the vastness of space was no longer an insurmountable obstacle, that landing on distant worlds full of life was no longer just a pipe dream.

What happens when this colony ship's crew arrives at their destination would forever change humanity's outlook on the rest of the universe, as well as what could be deemed possible. Supernatural beings, energies unexplainable, and most importantly, sapient organisms all populate this mysterious, fertile world. In all of its extensive preparations, is the Eclipse versatile enough to tackle the task assigned to it? Or, more importantly, is its crew?
