Effect of Nations
by Martian Author reviews
In 2148, a small team of American scientists and explorers found the greatest discovery in Human history; alien ruins on Mars. For the next two and a half centuries Human governments and corporations flew out from Earth, carving great empires and propelling Humanity into a new golden age of peace and prosperity. And in 2397, a Japanese explorer answered Humanity's oldest question.

How To Invade An Alien Planet
by roman566 reviews
Ah yes, Alien Invasions. The favorite past time of Always Chaotic Evil aliens. Mass Effect has couple of races like that. Surely such Sufficiently Advanced Aliens should have no trouble with conquering one Insignificant Little Blue Planet, right? It's not that the planet in question has faced so many failed invasion that the aliens inhabiting it wrote a guide to help invaders...

The Human Effect
by Leona-do reviews
Planets with their own consciousness. Collective consciousness of species. Magic. These are a few things that most the galaxy didn't believe. How will the galaxy react when all these things they dismissed as fiction were actually true. The species known as Humans would prove they were real. This is the Human Effect.

The Fourth Council Race
by Knight Vigilant Koren reviews
A few minor and realistic changes in the decisions made by the leaders of humanity drastically altered the path of Citadel Space and the Reaper War. This is the story of caution and planning over recklessness, the path of the juggernaut over the glass cannon. This is the story of humanity as it should have been. A power the Council has to respect, and one the Reapers can't ignore.

The Citadel is but a shadow of its former glory. The Terminus systems led by the Batarians and Salarians stand as the new masters of the Galaxy. Or so they thought? Heavily AU. Humanity based off of the Expanse T.V series. HFY.

The name 'Enigma' is one that is whispered all across the galaxy. It is both respected and feared - someone who rivals the Shadow Broker himself in the field of information brokering. Many things about him are unknown - who he is, his motives, his origins. But one thing is certain: he is not from this universe. SI. Main story is consistent, potential AU deviations elsewhere.

Alternative Humanity - The Lost Sol: Redux
by The Glorious Reader reviews
What would life entail with the disappearance of the sun? How would humans survive in a world without the very thing that sustains life as we know it? How would this upbringing effect the mass effect universe a whole when humans enter the galactic fold? Heavily based off of Orez Lanrete's original story, which he has allowed me to work on and continue.

by Flick262 reviews
In 1890 the Martians invaded Earth, in 1940 Earth invaded Mars. Humanity has never been the same. Told from the views of people (and aliens) on the ground, this is a compiled history of Humanity from the Martian invasion and leading up to the Shepherd's Sacrifice and perhaps beyond.
