It is the year 3070, and Mankind is once again at war. The battlefields of the future are dominated by fierce, robotic war machines known as BattleMechs, and under their auspice empires have risen and fell. Now with the worlds of the Inner Sphere once again facing the drums of war, two mercenary units have set off on their respective missions, their only tie a common ride upon the back of a JumpShip.

Yet when a cosmic accident causes a misjump, they find themselves thrown into a world that they cannot fathom: a world where magic is a force of nature, where mythical creatures live and thrive, and colorful ponies live protected under the aegis of their monarchs. New choices lie ahead, decisions must be made, and the inner character of Humankind will be put to the test when the question is asked: to conquer, or protect?

--------

It is the year 1023 after the ascension of Celestia and Luna to the dual thrones of Equestria, and Ponykind is at peace. With Luna cleansed and Discord sealed away even more thoroughly than before, all looks bright for the future of the colorful equines. With friendship and optimism, they face each day with hope and vigor.

Yet, when the heavens scream as a foreign object tears its way into their reality, the princesses and their subjects face a new threat that they cannot fathom: creatures and machines from a world of death and darkness, where magic is unheard of and the avarice of powerful men drive the engines of war to crush the innocent under their bootheels. Can they survive the coming of these coarse beings, and can they maintain the magic of friendship in the face of Man's Inhumanity?

A crossover with the Battletech universe, though this is an alternate BT timeline of my own devising. [WARNING: Fandom related material and fanboy rant to follow. Non-Battletech fans won't care, read at your own risk.]

Because **** the Word of Blake and their munch-tastic "armies from thin air" BS. Yes, I know the Clans were almost as bad, but at least they had some sort of justification in-universe. Wobbies? No. Just no. I don't care that it was 15 years, you don't go from "fringe group of mutually-antagonistic and argumentative sub-groups following various degrees of religious mania" to "WE ARE THE SPACE NAZIS ALL WILL BOW BEFORE US" like that.

So for BT fans, this is a 'verse where the Second Star League is still around, the Wobbies still had their temper tantrum though it was smaller and more in line with a bunch of religious fanatics. No stupid "knock everything down for ClickyTech" Wizkids/Fanpro approach, nor any "hey let's shove a bunch of cheesy Level 3 stuff at the players to make the game even more complicated" Catalyst Games stuff. This is just good ol' fashioned 'Mechs wailing on each other, only with ponies. Who will also be wailing on 'Mechs. GLORIOUS.

The Autobots have awoken from a deep hibernation, with wounds from a battle they don't remember. If that isn't worse enough, they're also in unfamiliar territory, a whole new world called Equestria. With almost all of their forces either dead or missing, the robots in disguise will have to earn the trust of this world's inhabitants (which is mainly made up of a bunch of talking ponies) in order to find out just what happened to them. Many will fall in this tale, but who? And how many? Generations clash when two of Hasbro's most well known toy franchises come together in a story that will leave both worlds in pieces!

Hold onto your hooves: It’s a fic about a girl who loves fics of people getting sucked into Equestria, who wishes she could be sucked into Equestria, who writes a fic about a girl who gets sucked into her own fic and lands in Equestria, and is sucked into Equestria; T’is written by a girl who writes fics who wishes she could be sucked into Equestria. IT’S FIC-CEPTION! I’m sorry. -_-
I got bored and inspired one day and wrote this first ponyfic on a whim. Not sure where it's going, but I think if I have fun and nudge it along naturally, it will turn out well. ^^ Expect lots of edits and crazy happenin's, and please give me any suggestions. I hope many people will enjoy it.

Daisy Dreams, master of lucid dreaming and a rare earth pony in the field of subconscious investigation, enters the dreams of troubled ponies to help them overcome their troubles and get to sleep at night.

Twilight Sparkle believes she has perfected a process to allow Earth Ponies and Pegasi to teleport. Unfortunately, in the Land of Ooo, a bubblgum-haired princess is about to run a similar experiment. Will even all of the friendship in Equestria be enough to settle Finn down? Will Pinkie Pie ever get her doughnut? Perhaps along the way, everyone will learn that truly, friendship is ALGEBRAIC!

Instead of being killed in the cold Antarctic by Dr. Manhattan, Rorschach finds himself rematerialized in a strange new, pony filled world. He finds himself drawn into the lives of the ponies of Ponyville but some ponies fear that this sociopath will bring danger and darkness to an otherwise peaceful existence. Will the mane 6 help Walter Kovac find peace within himself or will he bring them all down with him in his cold views of reality and existence?

Humans in Equestria? Naa, that's been done to death. What about Ponies in Equestria?

When a clever pony from the human world finds herself in the land of intelligent Equestrian ponies, how will she react?

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.

Now with its own TV Tropes page

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

Special thanks to my girlfriend for her help.

The reign of Morgoth in Arda is over. He has been defeated by the Host of Valinor and the Valar have bound him once more in the chain Angainor and cast him through Doors of Night into the Void. There he has drifted for many long ages, pondering his deeds and his defeats until Ilúvatar comes and offers him a chance at redemption. Softened by ages in the endless Void, Morgoth accepts this chance at freedom. He is given a new body and sent to a new world with the task of learning the values he has shunned for so long. In this new world, under the watchful eyes of Equestria's Valar, the Dark Lord will come to realize that there are yet things greater than the power of darkness.

Also yes, I understand that there's no "e" in Silmarillion, it's a pony pun. Sil-mare-illion. Geddit? GEDDIT?
