Author's Notes: Bioware owns Mass Effect.

- Welcome to my Mass Effect fic! Much like my Harry Potter fanfic, a highly unsatisfactory ending combined with numerous head-scratching plotholes has inspired me to write a fanfic of the Mass Effect universe. As a warning, much of this story will be AU. Slightly less in some areas, slightly more in others. I will say for now that the ending I have in mind is wildly different- the purpose of the Reapers will not be summed up in one Xzibit meme.

- additional note: I've completely rewritten the prologue, for various reasons.


Prologue

Awaken. Begin the March.

In the dark, empty void between galaxies, three red lights flared to life. A massive ebony hull turned to face the Milky Way galaxy, focusing on a densely packed nebula on the Norma arm. This was not supposed to happen. For a hundred thousand cycles, this had never happened. They had not received the signal from the modeller.

They had woken up late.

The waking signal had not come from the modeller at all. They received the call from the maintainer. The maintainer included its observation logs.


Error noted. Cycle was shortened by eight standard deviations. Inherent Mass effect usage. Modeller is unresponsive. Likelihood of interference extremely high. Species analysis performed. Physiological, genetic, and cultural markers remarkably similar to preceding cycle. Species is unsuitable. Probability of noise from preceding cycle causing interference is 0.9624. Species is to be eliminated.

Error noted. Mass effect use increased. Multiple species present. Second species analysis performed. Physiological, genetic, and cultural markers remarkably similar to preceding cycle. Species is unsuitable. Probability of noise from preceding cycle causing interference is 0.9963. Both species to be eliminated.

Error noted. Mass effect use increased. Multiple species present. Third species analysis performed. Physiological, genetic, and cultural markers identified as unique. Species is suitable candidate. Probability of interference from present species certain. Probability of noise from preceding cycle causing interference is 0.145. All species to be eliminated.

Natural selection overridden. Candidate species number 298 selected for uplifting and eradication of candidate species 173, 206, and 313. Eradication protocol has begun.

Error noted. Mass effect use increased. Fourth species uplifted by species 206. Species 298 eradicated. Cycle has now been extended by 0.00974. Modeller remains unresponsive.

Potential eradication of species 173, 205, and 313 by uplifted species. Observing.

Eradication failed. Cycle has now been extended by 0.01784.

Error noted. Mass effect use critical. Basic artificial intelligence detected. Advancement unacceptable. Cycle must end immediately. Will attempt direct manipulation of artificial intelligence. Will attempt direct reset of modeller. Will attempt direct manipulation of species 313. Sending waking signal to the Myriad. Sending march signal to the Myriad.


The March had not been performed for over 7035 cycles. Millions of red lights flared to life. A sea of black bodies, nearly invisible in the backdrop of intergalactic space, turned towards the Milky Way galaxy.


Codex Entry: Citadel and Mass Relays: Origin and Discovery

Although the Citadel was first discovered hundreds of years ago by the Asari, and studied continuously up to the present, only superficial knowledge has been gleaned about its origins. It was discovered in a fully functional state, activating itself when the first Asari exploration team lead by Maiden Renissia first entered the structure. An automated VI function quickly scanned the entire team, and the VI network used their physical forms as a template for a holographic guide, now known as Avina. This welcoming function, combined with the lack of any visible damage, has lead historians and archaeologists to theorize that the creator race, dubbed "Protheans," were a highly benevolent race that seeded the galaxy with these massive structures, and simply moved on.

Some theorize that the native race known as the Keepers were also the Protheans, but given their highly specialized role in the maintenance of the Citadel, they are much more likely to have been genetically engineered by the Protheans for that role.
