Two worlds, two peoples, two varying ways of life. For Equestria and its people, peace has been a staple of life for generations under the watchful eyes of their alicorn protectors. Resources and necessities for life are abundant, and the few times it has been threatened by external foes have ended in an Equestrian victory.

For mankind however, life is a brutal battle for survival in the war-torn hellscape of nuclear devastation. Violence and survival have been a mainstay for the last three decades, and only recently has a coalition tried to reestablish civilization. But the Earth is dying, and this last bastion of humanity only number around 50,000. For man, doom seems inevitable.

One day, two men accidentally discover something that will change the fates of both worlds forever. One man will discover Equestria and its prosperity, coming into contact with the very best Equestria has to offer. He will be shown kindness, and in turn, he will teach them understanding.

Regardless, the rest of Equestria will come to fear what they do not understand and after a tragedy costs humanity's good will, mankind will be left no choice but to invade in the name of survival. A sad tale, but one that history has repeated on numerous occasions. In the end, it will be up to a handful of individuals on both sides to find a solution and bring an end to the conflict. Will these two worlds come to terms and learn to coexist, or will one species be eradicated by the other?

Equestria is suffering.
Princess Luna feels alone, powerless and utterly depressed. In her weakness, she accepts an deceitful Ex-Guard back into her service, one who only wishes to manipulate her for his own gain.

Feelings of loneliness and pain couldn't have come at a worst time though. As things seem bad enough , war is on the horizon, Ponies go missing daily and Celestia invites a strange new race of beings into Equestria. A strange bipedal species from a dying world, who command little trust and carry possibly dangerous motives and desires.

As Equestria witnesses their Princesses fight over lies made and secrets kept, and civil war becomes ever more likely, in a place far away, Rainbow Dash has to survive in a world without friendship, and one bathed in fire and constant death. Her loyalties will be tested, and soon she discovers teaching loyalty and friendship to others is a task far harder than she expected.

Friends will be pit against friends, but will it even matter, when the portals of hell open, and darkness floods the land?

Sunset Shimmer and Starlight Glimmer are on their way to meet Sunset's friends in the Canterlot Mall when Starlight is hit with a familiar urge in an unfamiliar place. Fortunately Sunset's been there before...

Takes place during the third Equestria Girls - Magical Movie Night special, "Mirror Magic", but no spoilers.

TOILET USE WITHIN. Don't read on if you have a problem with that.

After discovering a new planet, the Tenno, a race of warriors, master of gun and blade and the warframe, and Lotus, the adviser, travel to find a brand new world with a species they've never seen. Unfortunately, they were followed. The Grinner, a ruthless military organization hell bent on wiping out the Tenno, arrive to find their enemy and an ally to them.

Now the Tenno are not only fighting for their lives, but for the ones of Equestria as well.

They used us, They destroyed our home, our family and friends, burned in the fires of war and greed. I'm Excalibur and unlike most, me and my team hunt down relics of the Orokin.

But after one mission almost killed me and stranded me on a planet from the distant past. I need to become the hero again. But I'll soon learn what it feels to have friends again and maybe even more.

But I don't know if I'm ready to forget the past and I don't think the past is ready to forget me. This is my story of how a group of idiots saved the world from utter chaos.

NOTE:
this story will take longer for updates due to my priorities being set on the Main Story's progression.
this also does not tie in with the main story in anyway besides from a few short appearances.

WARNING: CONTAINS STRONG LANGUAGE

Also the cover art was something I found on the internet I only added the name.

SPOILER!: This contains lore and what the Warframes really are. If you haven't played the Second Dream quest and don't want to be spoilt, do not read until you complete it.

My name is Karn, it's been over one-thousand years since I became a Tenno.

I've faced all sorts of horrors and challenges.
The grineer, a race of clones, seeking out others to stabilize their own DNA and hating anything or anyone not like them.
The corpus, a conglomeration of commercial and industrial interests, they acquire Orokin technologies and warframes to trade and sell using any means necessary.
The Infested, an ancient plague created by the Orokin to combat the 'Sentients' but has spread throughout the system.

Me and the new Tenno Greavus who uses the new Nekros warframe were sent to assassinate a grineer general, but Greavus struck a deal with the grineer and left me within the ship while the grineer tried to take my warframe for experimenting. Long story short, they failed.

I barely managed to escape to the void in an attempt to take down Greavus, but my Orbiter and Liset are damaged during flight.

My Orbiter exits the void right above a bright planet. With its engines down, the ship crashes right into a city on a mountain during an invasion.

I arm myself and leave the Orbiter, but for the first time in centuries, I'm not prepared for what greeted me... Small colourful equines.
