Summary
Over a hundred years in the future humanity has left their home system and joined an interstellar community after discovering the remains of an ancient spacefaring civilisation on Mars. Through the harnessing of element zero and dark energy, and with the technology of the precursors, all advanced civilisations travel the galaxy with the aid of a technology they call … Mass Effect.
Attempting to make her own path away from the one that life set out for her, Lena Kieran Luthor enlists in the Systems Alliance Navy. A few years later, wanting to see more of the galaxy without looking through the bulkhead of a warship, Lena convinces her superiors to send her offworld for additional training at one of the most reputable institutions out there: The University of Argo, on the planet Krypton.

Summary
In most universes, the Gates opened in low orbit above Pluto, others to their equivalent, leading to a shared dimension connecting all of them together. For the worst, as it would seem, as the Imperium of Man uses this new beachhead to launch invasions into every sci-fi and fantasy universe one could imagine.
Welcome to the Janus Chronicles. Where we will explore ever possibility that comes with this premise. And if you have any suggestions on what crossover event should happen, or what characters should meet, please let me know, and I will see if I can incorporate your idea into the story.

Summary
Orders fade. Only the ghosts remain.
Twelve years after the Aegis incident, Commander Elara Shepard is still chasing ghosts—some wearing Alliance colors, others with scars like hers.
To expose the truth, she’ll join forces with old friends and older enemies, and learn that sometimes the line between justice and obsession burns hotter than the fires that made her.
Former N7 operative Elara Shepard has been living off the grid since walking away from the Alliance and its lies. When whispers of the Aegis cover-up resurface—along with evidence of falsified reports and buried missions—she launches her own covert campaign to drag the truth into the light.
With Garrus Vakarian at her side, she’s forced to confront every ghost the Alliance left behind… including the one in the mirror.

Summary
The Gatekeeper made a mistake. A mistake that ultimately cost Izuku his mother. Guilty for what he has done, he asks two of his siblings to help fix things. Now with Izuku having the power of a Star Wars-themed system, he is determined to change not just his world but the entire galaxy and beyond for the better.

Directive Unknown is a collection of standalone one-shots set within the universe of File: REDACTED.

Summary
After a day from hell, disgraced C-Sec Officer and ex-Alliance Lieutentant Caitlyn Kirramman is approached in a bar by an old friend who makes her an offer she cannot refuse. Together with a new band of misfits from all over the galaxy, they must journey to recover an ancient Prothean Artifact that could cause the end of all galactic life.

But, with an Asari Commando, a genius engineer (and old friend), a Krogan preservationist and, a Quarian medical expert by her side, all under the command of the grumpy Turian Captain of the custom frigate 'The Sinestrus', surely it can't be that hard?
First though, she has to get the pink-haired mercenary they just broke out of custody to stop flirting with her and cooperate...

Summary
Alec is promoted to Captain and has to lead his team for the first time instead of just following orders. He later gets assigned a specialist on Daemonic artefacts to his team. If getting used to a new role was difficult, with this new chaotic element, it gets even more challenging.
Let's be real, I just wanted Magnus with a mind meld ability. :D It is light military sci-fi/fantasy focused on relationships, TSC characters in Mass Effect AU with my own tweaks. (You don't have to know Mass Effect to understand this setting; it is just sci-fi. :) )

Yet Another Attempt on Jessamine Kaldwin's Life by broken_ankle
Fandoms: Dishonored (Video Games)

Summary
The muffled sound that followed, and the ones after that, burned Jessamine's terror away to make way for hot, raging fury at herself. She had stood in the Council chambers and been respectful as they dismissed all of her requests without any deliberation. She had been ambassador to Palaven when tension from the First Contact War had still been high. She could maintain her composure during whatever was happening outside her office.
Someone takes advantage of the absence of Jessamine's bodyguard to try to kill her. Not the best of timing, all things considered.

Harry never asked for this. After everything—the war, the loss, the battles that had stripped him of nearly everything—he just wanted to rest. To finally be with his parents, Sirius, and Remus in whatever lay beyond death.
But fate had never been kind to him.
Instead of peace, he wakes up in the distant future, reborn as Ben Shepard—the son of Jane Shepard, the infamous Butcher of Torfan, a woman known for her ruthless efficiency and battlefield prowess. Thrown into a life aboard Alliance ships, constantly relocating with his mother’s assignments, Ben finds himself struggling between the echoes of a past life and the reality of his new existence.

Summary
If Roy was hoping that taking Edward out for drinks would help him wind down after their first joint mission in a while, then he was sorely mistaken; somehow, miraculously, Ed manages to look even twitchier in the middle of a club with a drink in his hand than he does in the middle of a firefight with a gun. He barely glances up when Roy flops back down into his seat with his own newly refilled drink and sweat on his brow from dancing, instead just going back to scanning the crowds as if expecting someone to throw a warp out or something.
Well. If Elric won’t have fun on his own, Roy will just have to make him have fun.
Or, after their first joint mission in a while, Spectres Elric and Mustang finally fall into bed together after years of sneaking glances through the corners of their eyes. Roy hasn't acted upon his desires out of fear of ruining their working relationship, since they are quite good combat partners when they do share missions. But maybe he's put a little too much thought into how he thinks Ed's feelings might change after sleeping together, and not enough thought about his own.

Summary
In the Sumeru System, one of seven systems that make up the Teyvat Galaxy, a plague has spread. From plants to animals to people, the Withering knows no bounds and shows no mercy. Driven to desperation, the Grand Sages send Sumeru's best, led by General Mahamatra Cyno, to find Lesser Lord Kusanali and finally put an end to Sumeru's suffering.
With dozens of unanswered questions, a ship too big, a crew he barely knows, and a general feeling of unease: Cyno's not entirely sure what he's signed up for.
On top of that, his past connection and growing affection for his head medic is not making things any clearer.

Summary
“We’re with you, Commander.”
It should bring Maggie comfort, she knows that, but she almost wants to scream at them to take the out.
Back on Akuze, her crew had no idea it would end up being their last mission. In this line of work, anyone hardly gets that heads up.
---
After a mission goes awry on her watch, Commander Maggie Sawyer is transferred to the Normandy, a ship of outcasts lead by Captain Henshaw.
Unable to convince the Council of the impending dangers of an ancient race terrorizing the colonies, the crew sets off on a journey to see if they can prevent disaster. Decade-long secrets uncover, enemies start teaming up, and the Normandy picks up a reputation everywhere it docks, for better or for worse.
Even with the threat of imminent doom over their heads, Maggie finds that a certain recruit teaches her how to actually live the future she is fighting so hard for.

Summary
three and a half minutes in, just after check-in, ed breaks the tentative unspoken truce between them to not bring it up. "you're mad at me."
roy is. he wishes he weren't, at least right now. but he's furious, and hurt, and currently very, very scared, because ed doesn't know how long his rebreather's going to keep him upright and shouldn't be wasting the oxygen to speak. "i don't want to talk about this right now, spectre elric."
with typical ed subtlety, he says wryly, "well i don't want to die with you being mad at me.” a deep breath. "so now i wanna talk about it."
Or, the one where Counselor Roy Mustang's boyfriend prized Spectre, Edward Elric, gets injured on a mission and calls his lover boss for help. In the midst of this they both clear the air and muddy the waters of what exactly they are to each other.
