In the magical land of Equestria, two alicorn sisters raise the Sun and the Moon every day to give the world a night and day cycle, basic for the survival of life. There are also two alicorns who rule over two very core aspects of life and harmony itself. Those are Love and Friendship. While not as ancient as the two sisters, all princesses are essential to the world's balance.
This balance is also sustained by the hard-working ponies, who make the seasons change and manage the weather to fit their needs, so everypony has enough food and water, and every animal is also attended to assure that any of them are caught in the changes of seasons.

But what about the planet itself? What about Mother Nature?
This is the question that Gaia asks when she arrives to this foreign world. After so much work her son persuaded her to take a long vacation in Equestria, saying that she needed one and assuring her that he would be in charge now, and she must take a break. But what can a several billion-year old alicorn possibly do to pass her time in this land?

(SimEarth/MLP Crossover)
(Timelife of Gaia's life 'till the start of the story)

Ten years ago, the Griffon Empire opened a portal to a strange new world and tried to annex it. In the peace settlement that followed they lost control of the province containing the portal. Since then, the Griffonian Democratic Republic had been completely isolated, surrounded on all sides by a hostile empire. Now, for the first time, a visitor had been allowed.

When humanity is on the brink of destruction, they shine brightest. When men have nothing left to lose, they put everything on the line. When the children of Adam have everything taken from them, they return the favor. With interest.

I've read a few TCB fics with humans winning, but I don't think I've seen it done this way. Enjoy the ride. First serious fic, will still have a few jokes though. I can't take anything too seriously. Hope you like it.

It has been one of the closest guarded secrets of Canterlot's royalty. Deep in a specially constructed dungeon, surrounded by warding spells and powerful magic barriers, exists an enigma. Within a cage that could only be described as something out of a nightmare, it waits and watches all of Equestria. A creature that cannot age, is immune to disease, does not thirst nor hunger, and resists all injury. But, it also holds secrets and knowledge that could safeguard the kingdom. Its powers are frightening, but it is civil enough for debate when patience permits.

Princess Celestia has sought counsel with the creature before, enduring it making deal after deal for its services. The Princess walks a fine line when dealing with it, knowing full well anything could give it an advantage despite its imprisonment. She has had to go back on her word in these dealings, and from this a deep animosity between them has been born. It is a necessary evil as she is convinced this is a being capable of untold evil far and above anything Equestria has ever dreamed of. So long as it remains within the confines of its cell, her kingdom is made safe. So much magic has been woven to ensure that, there is little chance of escape.

So long as the magic holds, there is no danger. So long as the cage remains strong, the nameless creature stays enthralled in his cavernous dwelling. If that were to change--if the magic failed--not even the wisest could say. But one thing is assured, it does not bode well for Equestria.

Dusk Shine has dealt with many trails throughout his life. From clashing with Nightterror Nebula to outwitting the mischievous Eris to thwarting King Nymphamos’s invasion, he'd seen it all.

All in all, Dusk Shine would admit that life was hardly easy. And now, Dusk finds that his mentor's self loathing is the least of his problems as he finds himself thrust into a world where he and his friend... are mares?

A warrior from a distant land is stolen from her home and brought to Equestria — literally kicking and screaming. Worse still, she is told that there will be no return trip. Can a woman who has known hell and battle her entire life grow accustomed to a land without such hardships, or will she fall back into old habits?

League of Legends < > My Little Pony

Anypony would have laughed if you'd told them that Discord was flirting with Twilight Sparkle a few weeks ago. She'd never give him a chance, right?
Well, once his spectacularly obvious advances on her commence, Equestria is shocked; she isn't out right rejecting him. In fact, she may even be interested.
The HORROR!

"My lady once wrote in her very personal and very secret diary that I have problems appreciating personal space. I beg to differ on that sentiment." - A Butler commenting on Professional Discretion -

I'm a Butler. My friends, the imaginary ones at least, call me Butler. My job, looking after my lady, can be...challenging at times, but rewarding. Lately the job's become a little more difficult, especially after my lady's sister returned from the moon and the parliament decided to try and pass an entire bill just to be able to legally get rid of me. But managing the chaos is part of the job description, even if it means I must secretly become my lady's knight captain of her personal bodyguards in order to keep my job. Though even I could never have anticipated having to train knights cunningly disguised as maids to stay one step ahead of the nobles. Ah, the things I do for my princess.

Twilight Sparkle has read about about what she believes may be an ancient library deep within the Everfree Forest called Ravenspire and, friends in tow, she heads out to find it. However what she finds inside this place is a creature, ancient beyond reckoning, desperately clinging to memories of a time long past when the kingdoms of Chaos ruled and all paid homage to the Ruinous Powers.

Added the human tag for way later. Like around the end, for like a thousand words.

Down voted by Commander Ponysun, so you know it's good!

This story is a sequel to Iron Hearts: Book 4 - Emerald Dawn

An MLP/Warhammer 40K crossover, part 5.

With their plan established and put into motion, the 38th Company begins the long and unwieldy task of planetary defense, fueling the arcane energies that may yet unsteady the Empyrean and spare their fleet from an enemy without number or mercy. The inhabitants of Centaur III and even the abandoned aggressors help where they are able, but as their foes grow in number and destruction spreads across the planet, the war for the Centaur system has become a bloody race against time.
All the while, the grim culture of the Chaos marauders continues to mingle with the enlightened benevolence of their equine allies. Tempers fray and allegiances blur. But the die has been cast: Equestria and the Company will survive together, or be snuffed out together.
And even should they succeed, what future awaits these unlikeliest of friends?
For there is no peace among the stars. Only an eternity of carnage and slaughter, and the laughter of thirsting gods.

ALL THE EXPLOSIONS. JUST, ALL OF THEM.
