The warp spew out existential headaches for the Citadel Council. *Pending Rewrite.

In 2148, explorers on Mars discovered the remains of an ancient spacefaring civilisation. In 2157, mankind opened the Shanxi-Theta relay and encountered alien life. But it was in 2155 that everything changed, when unwanted guests as ancient and arrogant as any Reaper arrived in the galaxy, dragging with them unwitting tagalongs.

Fire can burn, it can hurt and it can kill. But it is also warm and comforting. Fire can bring retribution upon its enemies but can also be a beacon in the darkness for those who are lost. The citadel council and the galaxy as a whole will learn soon learn, as a mysterious fleet suddenly enters the orbit of a terminus planet. Primarch Vulkan and his Salamanders bring fire.

Death is common as apart of life growing up on the most violent Death World in the Imperium. A home world that makes even the most dangerous of missions seem like a lovely vacation. It is not common to be cast through the Warp and into a completely unknown reality. Little can ever truly bother a Catachan though, and thankfully this reality still has plenty that needs killing.

This is not a story about heroes. Nor is it about great villians. This is the story of the rank and file troopers just trying to survive another day. The moral high ground, the low ground, it doesn't matter as long as you survive.

Xeno loving hippies are dead! The slaughter begins

For millennia they slept beneath the deserts of a faraway planet. Warriors created to fight as pawns in the wars of the gods themselves. After awakening to find humanity had reached the stars, the last Pariah leaves the confines of the Tomb world and enters a changed galaxy.

massive Changes to warhammer 40k lore in that main character's mother is a grey Knight that has the Power armor sink into her body thus not needing a Power armor since she basically is one. linked to kevinyu's main story. Before eden prime and the 212's deployment to eden prime

this one-shot describes how mortarion finds the planet where they start to research and harvest the gas named vespine x which they then make the flesh eater virus. this one shot is in conjunction to kevinyu's warhammer mass effect story. i own nothing of warhammer 40k or mass effect

In the future, where there is only war, sometimes desperate measures must be taken to secure the survival of a few. But when that measure leads to a place far different from what they know, can the Eldar adapt to a new reality, where there is more than only war? Also, what is a monkey?

The Council has encountered a power that is so massive, so overwhelming, that they cannot hope to fight it. Matriarch Benezia instead sets out to negotiate for the Council's continued right to exist. Patreon sponsored one-shot.

A salamander of the name (y/n) (l/n) is killed on the battlefield to avenge his battle brothers death, but the emperor decided to send his soul to another universe to keep fighting for the human race...and xeno alike...But if the emperor wills it, it will be done. That is the space marines sole purpose.

After being thrown into the tides of the Warp, the Space Marines of the Iron Sentinels chapter find themselves thrown into the mythical past of mankind and engaged in a war that threatens to see humanity wiped out. Threatened on all sides by Chaos and heresy, will they succumb or remain faithful to the Emperor's Light?

No Imperial records of the Second Primarch or his Legion of Adeptus Astartes exist. They have long since been purged on orders of the Emperor, yet this does not mean he did not once live, nor that he does not still live. In a Galaxy eerily similar yet foreign to the one he once inhabited, will the Primarch of the Second Legion be able to survive and adapt or will he die forgotten?

Shepard's mission to stop the Collectors had only just begun when she receives a strange distress call. She directs the Normandy to an uninhabited planet, where she finds four strange people, people not even from her universe, but from somewhere else. Somewhere far more hostile than her universe. A universe where something like the reaper threat has another name; Tuesday.

They came to this galaxy many millennia ago, some say even during the era of the Sea Serpent. They sought refuge and soon they rebuilt; returning to their former glory. Some thought them to be Gods. But just like their creators, they too vanished, never to be seen again. Until now. Heavy AU.

Commander Jane Shepard has done everything she could to defeat the Reapers. Yet the galaxy is a cruel place and she must once more assemble her team and do the impossible and prevent an even more devastating war. Story set after modded Mass Effect 3, thus with destroyed Reapers but with a still living EDI and Geth. I own nothing and all IP belongs to their respective owners.

A fusion of ME and 40K universes , different in many ways but one thing remains: in the grim darkness of the far future there's only war to the laughter of thirsting gods.

Leman Russ searches for a way to heal the Emperor and save the Imperium. There is a solution but it is not something that is conventional knowledge in the Imperium. Not even in the galaxy. There is no way for the Primarch to know when and where he will finally be able to achieve his objective. Nor if finding the solution is the hard part.

And Imperial Battlefleet is lost in a warp storm and finds itself in an unknown location. They will be faced with circumstances that will put them in both mortal and moral danger. T for Possible Language and Violence. Updates irregular, this is a private project so it updates whenever the author stops being lazy and writes.

Shepard is back from the dead and primed to go after the collectors. Now she needs to gather a team and hit them hard. There are some new face, some old friends and even some unexpected arrivals and Allies. How will the newcomers from the Grim Dark 41st Millennium effect the way of life in the Mass Effect universe?

What happens when three 'heroes' get dumped in an unfamiliar galaxy with only an inkling as to how? Why you get a decidedly unlikely adventure of course! Set in ME1 and before Gathering Storm.

Using the Nobledark Imperium AU. Jane Shepherd, hero of the Skyllian Blitz and savior of the Milky Way, was now stranded in the Milky Way. Or at least a version of the very same galaxy. Things become rather questionable when this former commander ends up living in a fascist utopia where secret police monitors all communication, taxes are paid in troops, and live with total war.
