The Reapers trap was perfect in its design. Their execution refined over billions of years, their technology refined since the dawn of time itself. Right up until Someone Broke the Trap!

When the Technocracy loses a science ship while exploring a nearby galaxy identical to the Milky Way, what first is a simple search and destroy mission becomes something much more complicated when it turns out, there are humans and other aliens there too. This'll be interesting... WARNING: Contains Plot Deviation and Shitty Dialogue

A Codex exploring the History and Lore of the Stellar Effect Universe

A new galactic power, the Solar United Nations, has taken a mantle alongside the Citadel Council. Two powerful forces acting in concert to form a stable, galactic community- Where did these space creatures come from? What do you mean the Humans Summoned spirits- No! Don't Adopt the Quarians! (One-shot, but can expand later).

The Empire is in a time of Peace and prosperity, After Crown Princess Sarah Led the Fremas Offensive during the Fremas Rebellion where Imperial Forces clashed with Traitors and Renegade Elements of Imperial Society, Only for the Empire to finally Emerge Triumphant, But a new threat emerges and a Whole new galaxy is now aware of them, Irene Protects, Let no one be found wanting.

In a distant yet expansive corner of the galaxy, many races rose and fell without anyone noticing. Yet a collection survived their ordeals and now look outwards. They bring Ideals, Peace, Prosperity, all under the UNSA and its Custodianship. When the Quarian Migrant fleet encounters an Expedition fleet, the nomads find a new home and a new family.

My favorite race in Mass Effect is the Krogan. So imagine my surprise waking up as the Geth. I recently been reading stories where one person becomes a member of a team or a species so I thought about combining mass effect with stellaris. I do not own any of these established properties

Somewhere along the lines of history, two Humanities would evolve in two galaxies. One of these Earths would unite an entire galaxy under its flag and defeat the unbidden. With no threats left in its home space, the United Nations of Solar Species decides that the Reapers make good target practice and invades to stop them. Extreme OP Humanity, AU, and curb-stomping Reapers.

Over many cycles, the Reapers have wiped out many civilizations. However what happens when one of those civilizations survives? What happens when one is able to rally several other species that evaded the trap as well? How will the council react to someone that surpasses them? Stellaris/ME/RWBY crossover. HFY. (tempora hiatus so I can focus on my other works and school).

Senator Simon Moreno is sent to the Citadel as part of an official visit from the Commonwealth. Little did he know that news of the Commonwealth had already elicited some odd reactions amongst the Citadel species, particularly the Turians. Sequel to 'The Address'.

Sent with a delegation to represent the Citadel Council, Councillor Tevos has her eyes opened to a much more powerful and larger community, making her rethink how the Council has functioned for centuries. Along the way, she meets a prominent human diplomat.

An empire torn out of its galaxy stands ready to burn the stars once more, in the emperor's name.

Humans discovered creatures that wander the stars, and the galaxy will never be the same again

The Council made the discovery of a lifetime during their expansion. But that discovery would haunt the Council. For the first time they could see, the universe was infinite and full of horrors. They were but a speck in the cosmos. The echoes of those that came before could be heard, a re-awakening had begun. Would the Council become no more than an echo throughout the stars?

Its a game. Or is it? Turians get to welcome the denizens of a Stellaris based civilization that is hell bent on the extermination of all aliens, well except for some. Of course the Turians fired first, Galactic laws and all that bullshit. In return they are faced with an enemy that doesn't play fair. Warning: HFY. Read at your own peril AU Fic. Edit: On indefinite Hiatus

In 2075 CE the Manswell Expedition dissapeared. In 2181 three ships of unknown origin arrives in the Milky Way. Who are they? AU.

The Citadel Council have only discovered an estimated 1% of the galaxy. It's only natural that something out there can... surprise them.

Humanity reached for the stars earlier than expected, their colonies reaching out far and wide before the turn of the 22nd century. Yet they had not encountered another alien species; that is, until an exploration ship enters a miscalibrated mass relay and crash-lands in the homeworld of an alien species. How would humanity evolve when welcomed with kindness instead of violence?

A century ago, humanity peacefully made first contact with the wider galaxy. Now, as a fledgeling Alliance tries to secure its place in the wider galaxy, a long lost branch of humanity sets its sights on the chaotic sprawl of the Terminus Systems.

The Collector Base has been destroyed, never to threaten mankind again. The Reapers took offence at their puppets destruction and decided to take away Shepard's escape, forcing her into an abandoned part of the galaxy. Instead, Commander Shepard is thrust into meeting an entirely new race of aliens! Four of them in fact. How will this meeting change the Reaper war?

Humanity have fallen, they forgotten what it makes us humans. To Ascend we must bring forth all our knowledge and might. The Broken Ascension must be completed. Humanity is Supreme and Ascension is a must. Note: I kinda made a mod for stellaris for this settings. It has all the main details. Just check "Ultimate Sol System" in the workshop

The galaxy played with forces beyond their comprehension, the Human race were now refugees, fleeing from what was certain extinction. Council space might be Humanity's only hope of survival. AU DISCONTINUED (Sort of, idea reforged as Echoes)

The Dreadnought Ventrau has been sent to the mass effect universe, what kind of change will it bring and what will happen to the species it comes into contact with?

Short story. All in 1, 3 Episodes. Mostly on the Stellaris side of things and all told in first POV. Sort of more crack than anything. It's just idea that I wanted to post but it sort of helps me set a new stage for Expansion Edition when I get around to finishing the final draft and posting it next week. New updates are featured in here, you'll know it coz it's obvious.
