A/N: Alright, since everyone else's codices begin with a timeline, this one will too, presuming it's not taken down on order of Support (someone who cared too much prodded me about it and I asked them just to be safe)

Unfortunately, a lot of this will initially be referenced from SupCom wiki. However, you will notice major changes from the formation of the Prime Worlds onward, and little things that changed (e.g. Proxima Centauri for first colony instead of Alpha Centauri, to celebrate that exoplanet discovery) before that.

This timeline is not SupCom canon, unlike the unit sizes listed in later codex entries which are measured from in-game. However, I must point out that colony growth rates here seem more sensible than canon… and the Empire-UEF power gap more sensibly small. All characters mentioned are not quite canon or entirely of my creation…

Codex Entry 0: My Modified Timeline, 2000 to 3850

2009: An aggressive project is launched by the United States of America, aimed toward putting a man on Mars.

2016-2056: Preparations for and the act of limited colonization within the Solar System by the various major powers of Earth, in response to the United States' actions.

2025: The Quantum Age begins with the successful transportation of a single cesium atom 10 feet through a "quantum tunnel" in a lab. This is fundamentally different from previous attempts which merely "copied" matter.

2032: A milligram of iron is successfully transported to the Moon's surface, using the combined output of 25 nuclear fission reactors.

2050: First living matter transportation test. Monkeys are successfully transported to Mars in 2055.

2062: A research base on Triton begins work on interstellar travel, having been transported there the previous year via a 0.26 second journey.

2108: First extra-solar colony on Proxima Centauri b. This endeavour's energy cost was deemed completely impractical for future colonization efforts. This was not due so much to the energy needed, since mass-energy manipulation and thus post-scarcity has already been achieved to a degree (which would grow in the coming centuries), but the technology to contain it as needed.

2110: Unification of human exploratory efforts, under the United Nations of Earth. This government would later rename itself the Earth Empire as an aristocracy emerged and solidified its political power.

2110-2184: After determining that sending genetically engineered human DNA patterns and a small team to initiate a colony would be best, using local mass and energy resources for construction and terraforming as needed (the technology is coined "nanolathing" as per old science fiction works), the UNE establishes the first sixteen colonies, known as the Prime Worlds. The colonists contributed greatly to the creation of the Quantum Gate Network, which allowed for much more efficient transit and expansion of the colonies by emigration from Earth.

2284: The First Great Expansion begins with the colonies of the Prime Worlds launching their own colonization efforts. After adapting over time to govern on an interstellar scale, the Earth Empire fully establishes Earth Command as its military arm. To maintain control over the rapidly expanding Empire, derivatives of the colonization suits are specially made to create units in the field, requiring fewer people serving in Earth Command to enforce order.

2425: The Second Great Expansion begins as many hundreds of new colonies are founded by the colonies founded in the First Great Expansion and older worlds alike. So far, no intelligent life has been encountered and many assume no other intelligent life exists.

2457: A survey expedition sent to Seraphim II does not re-establish contact within the standard window. A routine follow-up expedition is scheduled.

2490: A second expedition to Seraphim II also fails to re-establish contact with Earth. Seraphim II is marked "Hazard" on the ever-growing "Investigate Hazard" list. Due to unrest on the fringe worlds, Earth Command cannot afford the personnel to investigate at present. There are few who are capable of withstanding the reality of modern war for very long…

2492: An artificial intelligence is successfully implanted into a human brain and becomes part of the person's personality and abilities. The human/AI pair is called a Symbiont.

2512: The Symbiont program completes its experimental phase. Symbionts take up important tasks throughout Earth Empire space.

2563: The Third Expansion begins. The Earth Empire begins to show strain from having so many colonies and being of such technological level that they are essentially independent of one another.

2566: Procyon, a Symbiont colony, petitions for independence. The Earth Empire activates its secret "Loyalty Program" installed on all Symbionts.

2569: The first version of the Symbiont Liberation Matrix is distributed en masse for the first time by Dr. Brackman and the few Symbionts he had already freed. The Symbionts mostly lie low for now, awaiting the return of Brackman and their brethren from beyond the down-spin border of the Earth Empire.

2570: The Earth Empire is contacted by descendants of the Seraphim II expedition, who claim to have been taught many secrets by aliens. The Empire quarantines the sector and sends Commanders. First Contact between the Earth Empire and Seraphim proceed disastrously due to EarthCom xenophobia. The Earth Empire quickly develops a bioweapon and deploys it against the Seraphim near the end of this year.

2571.3: Contact with all worlds bordering Seraphim II is lost.

2571.8: All contact with EarthCom forces within 10 light-years of the Seraphim Quarantine Zone is lost.

2572: The last known Seraphim dies in battle. Most of the Seraphim had been killed by the bioweapon. The humans who had coexisted peacefully with them take up the cause of vengeance and spreading The Way. They call themselves the Aeon Illuminate.

2578: The newly named Cybran Nation tears into the down-spin border of the Earth Empire, liberating many Symbiont colonies and pushing deep into Earth Empire territory, while EarthCom is being beaten back by the Aeon. The Infinite War begins (though the name was coined later).

2590: The First Aeon Incursion begins, eventually ending with the desperate stand of Commander Williamson at the location thereafter known as Williamson's Bridge ten years later.

2618: The Earth Empire has lost control of most of its territory as perceptions of corruption and injustice boil over more than EarthCom can contain. With the many failures of EarthCom against the Cybran Nation and Aeon Illuminate, faith in the military is non-existent and open rebellion an everyday occurrence across the thousands of human-controlled worlds. Anarchy reigns through former Empire territory. It is during the massive advances into the collapsing Empire this year that the Cybran Nation and Aeon Illuminate collide in ideology, interests, and battle.

2624: The Earth Empire is formally dissolved, and the United Earth Federation is formed by the force of fear of the Aeon and Cybrans. For some odd reason, there is usually a lot of screaming about "BORG!" and mass murder-suicides whenever the Cybrans tried to pacify a settlement…

2640: The United Earth Federation finally digs in its heels manages to grind the battle lines to a standstill. Most of the rim-ward worlds (relative to Earth) now belong to the Aeon, and the down-spin worlds largely belong to the Cybrans.

2650: The United Earth Federation launches its first Incursion into Cybran space and exterminate as many Cybran civilians as they can find, before the Cybran military stops them and pushes them back.

2690: On the hundredth anniversary of the beginning of the First Aeon Incursion, the term "Infinite War" was coined for the present conflict.

Sometime in the 2800s: Contact between the Cybran Nation and the United Nations of Drell. The Cybrans repair the Drell homeworld from ongoing ecological disaster, and mostly leave them to their own devices in the name of promoting independent technological paths.

3000: In response to repeated UEF and Aeon Incursions, the Cybran Nation no longer mandates trying to encourage non-Symbionts to peacefully accept the change in control over settlements during Incursions. It is now up to individual ACU pilots.

3503-3504: Rhiza Sullivan and Xavier Fran are born.

3529: Xavier Fran and Rhiza Sullivan graduate top of their class from ACU pilot training, though Rhiza wet through the program faster than Fran. Unfortunately, in the name of having some measure of wisdom and he Aeon Illuminate being in a good enough position in the war, graduation from ACU piloting school is not permitted before age 25, and Rhiza enlisted a bit late, so she is 26 at this point. Both proceed to become highly renowned Aeon commanders.

3543: Rhiza achieves the rank of Crusader, the youngest Aeon commander ever to reach that rank. Fran lags behind due to lack of adequate demonstration of zeal. He focuses vastly more in battle on engaging and destroying enemy Commanders instead of killing civilians before they can escape, which is often the actual objective.

3740s: Rhiza and Fran assist Rhianne Burke in ascending to the throne after the last Princess, Miranda Burke, retired. The violence of this period is reckoned by some to be practically a civil war. Eventually, the compromise of accepting Rhianne, a known pacifist and student of Evaluator Abigail Toth, another known pacifist, being counterbalanced by selection of a more aggressive Avatar of War is brokered.

3760: Fran, still stuck at the relatively dead-end rank of Senior Templar (compared to High Templar on the promotion path), mentors a promising young recruit by the name of Jaran Marxon. The young man is piloting an ACU two years later, and quickly climbs up the ranks due to the endorsement of so senior a commander as Fran—though he is considered too soft for higher rank, Fran is still highly respected as one of the oldest surviving pilots—and making the right political connections.

3814: Appointment of Jaran Marxon as Avatar of War once he reached fifty gigadeaths in his total score (kills plus a fraction of each assist), which is the minimum required to qualify for that position. Marxon informs Fran and Rhiza that he feels extremely betrayed at being recommended for that position, and for them shoving him up the ranks so fast so that Rhiza doesn't need to deal with the paperwork. He also suggested that this was because Fran and Rhiza were more than friendly rivals, citing his new rank as why they couldn't knock some sense into his head. Marxon avoids social contact with the two from that point forth.

3815: Steven Hackett is born.

3816: Ariel Williams is born.

3820: Hannah Shepard is born.

3830s: Dominic Maddox (3831), Thalia Kael (3834), and Ivan Brackman (3838) are born.

3840: Hannah Shepard makes her debut as an ACU pilot. Cybrans mature faster physically and mentally than Aeon or UEF humans, and she is no different.

3841: Steven Hackett and Ariel Williams make their debut as ACU pilots. They and Hannah quickly become acknowledged as the prodigies of their generation.

3844: Black Sun is fired while being contested by the Cybrans and Aeon. Though the Cybrans controlled the Control Facility and had uploaded their Quantum Virus successfully, Marxon, who had come to Earth to see the end of his endless mountains of paperwork, stalemated Hannah's forces and forced Hackett to escape to another base in time for Ariel to sweep in and help Rhianne fire Black Sun while it was under largely Aeon control. This is the first instance of Rhianne becoming an Ascended being. Then the Quantum Rift opened, and though a significant part of the Earth populace was evacuated by cooperation between at least the UEF and Cybrans—Rhianne had not managed to broadcast at enough power to pierce the fanaticism of some Aeon pilots—Earth is bombed to ashes and the Seraphim War began.

3845: Jaran Marxon, having barely escaped Kael's purge of the Aeon military after her seizure of power, admits himself to a psychiatric facility run by Aeon Loyalists flocking to Rhiza and Fran's banner. He could probably have sought care from the UEF with far less trouble, as his face is nearly unknown outside the Illuminate. That wasn't because "few survived long enough to transmit it" as propaganda claims. No, it's because like Fran he wasn't one to trash-talk his enemies back when he operated in the field, and unlike Fran he had no habit of telling the civilians to use the time he spent fighting their defenders to get the hell out. Marxon was found to be repentant thanks to Rhianne's message, and psychologically no longer fit to pilot an ACU after 30 years of serving as the Avatar of War full-time.

Due to the blanket immunity of ACU pilots from persecution for war crimes and the not so minor fact that while ruthless Marxon didn't specifically take extra effort to go out of his way to kill civilians—except when testing the mettle of subordinates, or getting back at his old mentor for sticking him with this damned job—he was tolerated by the Coalition. He will also sometimes be hired to give speeches about how wrong the path the Aeon had taken was, though he is permanently barred from UEF and Cybran space unless governmentally invited.

Marxon served a few more times after his defection as an ACU pilot, fighting in defence of the planet the facility was on. None have passed. As a side note, he is mystified as to why people nicknamed him "dry tofu" (Gan Dou Fu) in Chinese, the second most common and second official language of Quantum Age humanity, for terminating all attackers.

3846: General Samantha Clarke is presumed to be killed in action on Capella, though the blast profile didn't quite match an ACU meltdown…

3847: Arrival of the Seraphim Separatists, who assist the humans in slowing the advance of Seraphim Imperium forces. It is revealed by the Separatists that while the Imperium is actually a democratic system and thus the name was meant as a joke, the Imperium were completely serious about teach the humans a lesson for their bioweapon on Seraphim II. However, it is also suggested that the Imperium seems to not be trying as hard as they could be, and the human factions found this plausible due to lack of Seraphim bio-weaponry use.

3848: Rhianne Burke returns, and the Quantum Rift is closed by use of technologies provided by the Seraphim Republics. Though suspicions abound regarding the motives of both groups of Seraphim, the Republics are for now accepted into the Coalition as a fourth faction. Oh, and Marxon confessed to Rhianne (who did not sense falsehood in his words) that his "killing" of Toth was actually a matter of putting her out of action… and then the Order of the Illuminate finishing the job to his surprise. He did not state why he previously claimed otherwise. She would probably put him through several walls if he told her he'd said it just to piss her off…

…Goddamn it, historians, now he had to run away, as fast as he could, and given he hasn't had a chance to stick himself in rejuvenation therapy yet… that not as fast as he would like, even if Rhianne didn't use her Psionics…

A/N: And that's how my fanfics begin, more or less. Marxon's fate varies in the three SupCom 1 endings, so I made him the butt monkey of many jokes, and stay alive so he can be the butt monkey of many more. On the other hand, he did get the last laugh by a) being lumped in with all other ACU pilots in not being persecuted and b) fobbing the paperwork mountain off on Rhiza. This also reserves another canon character for future hilarity.
