Author Note: This is a crossover between X universe series(X3 Terran Conflict, Albion Prelude) with some things from Litcube Universe like new sectors(Terrans are linked by Heretics End to Argon M148) and ships(Excalibur and Atlas FTW) and Mass Effect verse. I don't own these franchises but I own my Corporation inside my LU save.

Carrying on, technology in X universe is far more advanced than Mass Effect, so I will tone the numbers down a bit, the Commonwealth and Terran Empire also do not have that big of civilization, 1 solar system + Heretic End for Terrans while Commonwealth races have about 10-20 planets each.

To get idea about X universe, we need to start with timeline. I will not copy paste it whole so link will be on my profile.

There is also change here that Xenon are less murderous(more often than not) because of Effa joining Elder Races who promptly with Sohnen went to do their own things and do not care anymore about their jump gate network. So there wasn't a shutdown.

Also Commonwealth did not go to war with Terran Empire because... you will see. So it just went with cold war and progress of tech just like normal. Things are relatively peaceful between races.

Last thing I want to add is how it crossovers. Elder Races created Jump Gate Network in a small part of the Milky Way galaxy before Leviathans noticed them and asked to stop. So JG network is X Universe part of the galaxy while Relay Network will be rest. Elder Races do not interfere aside from saving Effa Xenon from destruction. Reapers also were programmed to not enter the JG network in it's basic code unless something emerged from it to not anger Elder Races.

Timeline for Sordahon(SDH) Corporation from its beginnings up to now:

Argon Year 730/Earth Year 2900

Argon Federation citizen Thomas Silver nicknamed Sordahon passes test to become an apprentice Mining Pilot of a rented Transport Class ship (TS) at the young age of 24.

He secures a small deal as a subcontractor with Teladi Company to mine various precious materials and thus his career starts.

Argon Year 735

After 5 years of hard work, some luck and heavy protection of PTNI Corporation security fleet, Sordahon managed to safely save enough money for a 2nd hand TS ship of his own, certain that he will strike it rich on his own and with help of a few precious contacts in Teladi Company. He became a battlefield scavenger. Using his now personal ship 'Mercury' outfitted with full shielding, basic upgrades to propulsion, cargo space and maneuvering thrusters, he journeyed through various sectors bordering Pirate and Yaki, in addition to occasional Xenon Incursion and small border skirmishes between races.

Argon Year 738

Money starts to accumulate during Sordahon endeavors however he is meet with a pirate ship(M4) ordering him to drop his cargo, Sordahon left without much choice and no defense weapon, complies. This event sets him back a few months but doesn't hurt his motivation. Through lessons learned he becomes more careful.

Argon Year 739

Finaly after 4 years and no more dangerous meetings with a pirate, he sells his cargo in sector 'Treasure Chest' and then proceeds towards Omicron Lyrae in search of another transport ship and someone to hire while planning to increase his fleet and thus increase his income. Perhaps even one day to have his own station.

Argon Year 742

Xenon War is over, Commonwealth dealt great blow to their forces, and they retreat beyond jump gate network to lick their wounds, and as they say 'war is money'. With a modest fleet of 4, Sordahon sweeps through the sectors with his 3 subordinate Pilots. Achieving what not many can say, enough credits to buy a new full fledged station, one of the cheapest ones, however also one step towards something greater.

Argon Year 743

A newly built Medium Solar Power Plant is created in sector Elysium of Light, it took some negotiation and money, but Sordahon managed to get a permit from Goner Temple to build his own station, and thanks to its proximity to main Argon sectors, it became a hot midway spot to get some quite cheep Energy Cells. Fully functioning after about 2 months, he reassigned his two TS pilots to filling his new Power Plant with Crystals required to produce Energy Cells and a few decent operators to this mostly automated production facility.

Argon Year 747

With his first space station being a success, Sordahon set his sight on creating a trading fleet, His Scavenging Fleet reduced to 2 Pilots first increased with 6 new employees and 2nd hand TS ships focused on making money. After some minor success while looting area near Interworlds sector that holds a Large Weapon Platform created to secure space from nearby pirate sector of Twisted Skies. A bit dangerous yet lucrative work allowed Sordahon to buy his first two Mercury TS with Professional although greenhorn Merchants who will trade various wares.

Argon Year 750

Scavenging Fleet numbers increased to 10 ships while Trading Fleet increased to 12 ships. Sordahon himself instead focused on planning for future inside his office of his Power Plant.

Argon declare war on Yaki and various border sectors become battlefields. Safe as he may be, Sordahon uses a good amount of his funds to set up two defensive Laser Towers near his station for peace of mind and also hires two merceneary heavy fighters (M3) ships with their pilots each ordered to protect the two fleets.

Argon Year 758

Entering middle ages of his own life, Sordahon starts to fear his own mortality more. During 8 years, his one station and two modest fleets increased by 2 Medium Mining Stations built in newly charted Unknown Sector Beta filled with various asteroids, one refining various Ores and the other Silicon. His trade fleet increased to 3 sub divisions of 10 ships and 10 Free Traders. While he scrapped idea of shot and miss Scavenging fleet and sent all 10 to the new Mining Stations as miners. However need for heavy load transport required purchasing a batch of 10 Mercury Super Freighters (TS+) class ships, 5 each for each mine for the stations to achieve their full potential.

Such expansion also required to create a separate security fleet instead of mercenaries. As such 1 Nova Raider M3 class ship was bought in addition to 6 Buster Sentinel (M4 Fighter) class ships. The small fleet was equipped with good weapons, shields and fully upgraded to face the threats. Their greatest strength was a jump drive which allowed them to respond to threats far away in a moment, powered by Energy Cells provided by Power Plant in Elysium of Light. The two Mining Stations each were instead protected by 2 separate Laser Towers.

Argon Year 760

News spreads around about newly found corporation originating from Argon Federation, it calls itself Sordahon Corporation or SDH Corp. shortly. Founding CEO Sordahon expresses his thanks to all affiliates and employees for making it this far, when interviewed if their current goal is expansion in mining and trading business, CEO Sordahon replies he is setting up a research station with yet undisclosed project. Various Media outlets speculate what a new corporation has in sight exactly.

Argon Year 761

Sordahon Corporation newly built Research station is fully built and outfitted with top of the line equipment in addition to a few recommended researchers by contacts from Teladi Company and various people Sordahon met along the way.

Project Origin starts at the interest of media outlets, it's focus is revealed to be Gene neIV/732 previously created by Asam Ahmad around 750 years ago, the Gene was commonly known by granting an average increase of lifespan by up to ten times, however it was scrapped due to chromosomal incompatibility allowing only females to use it. As such it was deemed failure, though a few patients exist and some were one of founding members of Argon Federation after First Terraformer War, expected to live at least 1000 years, another problem was introduced due to slowly becoming detched from life because of male relatives and loved ones limited lifespan.

Various amount of outcry and criticism is directed at Project Origin but CEO Sordahon ignored it, his 85 life long ago entered middle age and though he would easily live past 150 years due to current technology. He seeks more, though that information is not released.

Argon Year 763

The SDH itself grows, however progress on Project Origin seems to be stagnating. CEO Sordahon pours money into it and invites various famous scientists from around the Commonwealth. His Corporation now stands at 6 mining stations, 3 power plants, 1 research station and a Laser Tower Factory becoming SDH Corp. entrance into defense systems market.

CEO himself seeks more money possibilities across nearby sectors.

Argon Year 764

Kha'ak Race invades known universe, sector President's End is destroyed.

Panic spreads while various fleets prepare for war.

SDH increases its security fleet by 6 M4 class ships, 2 M3 class ships and one Argon Centaur Corvette (M6) class ship, boosting firepower and defensive capability of SDH Corp. significantly.

Battle of Omicron Lyrae begins.

Argon Year 765

Kha'ak Invasion Fleet is defeated with aid of rediscovered Terran Empire. Earth, The Jawel of Sol returns to known universe.

SDH Corp. remained unscathed through the conflict and started once again expanding.

Argon Year 768

Terrans reunite with lost colony of Aldrin that reveals various advancement in propulsion technology.

Argon Operation Final Fury successfully eradicates Kha'ak main Hub sector, Kha'ak race retreats from known universe never expected to return.

Xenon Hub is discovered and utilized by Terrans to connect to Aldrin sectors.

Terrans built first jump gate in a long time.

Terrans refuse to Join Commonwealth of Planets.

CEO Sordahon uses various contacts and bribes to request a meeting with Terran officials.

He is allowed entry into Sol System where he creates a small branch of his Corp. set on increasing relations between their Corporation and Terrans, but also trying to lower tension that started to brew.

Argon Year 770

CEO Sordahon gains enough reputation in Terran Empire that he is allowed to visit Earth.

Excited at the marvel of the home planet of humanity he once again starts to think of his age, this prompts him to make official query with regard to known living subjects of commonly known Longevity Gene.

Terrans are hesitant at first due to subject of query, but they give out the information when one of the subject females reveals her agreement, this then prompts other subjects to join.

Those subjects travel to SDH Corp. Research Station as guests and agree to help in completing the project.

Argon Year 772

Terrans are revealed to have planted spy network in Argon Federation.

Sordahon desperate from the events happening and threat of having to send his project helpers home if war were to occur, uses his now more vast funds to create one of bigger known Media campaigns in order to influence public opinion. Some sympathizers contact him and send additional funds. The focus of the campaign is warming relation between the two governments to a manageable level. Those include sponsoring various students for foreign exchange programs, funding various Terran Charity organisations, Inviting celebrities from both nations for light funny shows. Little by little the public opinion changes, CEO Sordahon gains reputation of a peace seeking eccentric.

Public pressure prompts both governments to have a bit more positive view over each other due to recent events. Both sides agree to a more stable peace and minor trade agreement.

Argons agree to Terrans view to limit AGI development to a dagree, however as they declare themselves a federation founded on democracy. It only disallows government research into war applications of that technology. Private enterprises and individuals are not limited though encouraged to be careful.

Terrans realizing it's as good as it can be regarding their laws, warm up a bit more but also create a private pseudo governmental company that keeps tabs on private AGI development in case of danger.

Known Universe enters an era of relative peace.

Argon Year 780

After another eight years of development, Project Origin advances to later stages. It is now capable of functioning and increasing longevity of male humans as much as female ones.

Completion period soon approaches however it becomes clear that the Gene development and distribution have taken and will take a significant amount of money.

News of Project Origin success spreads around like wildfire, every news highlight focus is placed on Sordahon Corporation and what they managed to develop. Media outlets describe this as entrance into new age, age of longevity and prosperity.

They also redistribute information that the gene is expensive and not easily created, thus SDH Corp. releases its own article about its advantages, disadvantages and price options.

These being increased longevity, upwards to a thousand years, perhaps more. However telomere shortening is not completely stopped and the user of this gene will still die once it approaches its end.

Price is set at 100.000 Credits — A price that can be compared to a small space shuttle or an expensive car.

There are also however benefits in certain options. Researchers who worked on the project get 80% discount on the price while an employee of the Corporation gets a 50% discount, provided they sign at least 40 years contract.

Sordahon Corporation massively expands due to no shortage of new employees and money made by selling Longevity Gene.

Argon Year 800

SDH Corp. experiences rapid growth of assets entering the stage to stand on equal ground with behemoths such as Plutarch Mining Corporation or Optimised Technology, Armaments and Shielding Corporation. Massive development of the corp caused them to buy several private sectors in addition to a special station as their HQ but also another supplementary shipyard which they use to sell various ships their now expanded research station produced. Experts say that their new designs approach OTAS in level and expect a friendly competition. Meanwhile Mining, Trade and Security Fleets are undergoing change into proper arms of the corporation and acquiring more and more employees.

Argon Year 840

Currently one of biggest corporations in the known universe due to their extreme growth after developing Longevity Gene. SDH Corp. stands now at several complexes creating defensive technology required to protect itself. About 1500 Free Traders flying various ships not limited to Argon designs or employees of Argon race becoming known as Trade Division of the Corporation. SDH Corp. good reputation became known to other races like Borons and Paranids becoming interesting job prospect for these races, making it now multi-race Corporation. The Mining Fleet became Mining Division now has expanded to 3000 various TS and TS+ class ships and six Mammoths Heavy Transporter (TL) class ships capable of transporting enormous amount of cargo in addition to capability of building stations. Station to Station supply system became a chore by reassigning employees so a completely new division was found to keep it running. Supply Division now manages 500 Dock Agents and Freighters.

Security Fleet shed it's shell of merely protecting the Corporation from threats, it now became Security Division holding power over several military fleets, each capable of devastating damage. They are also now capable of taking on various missions as governmental sub contractors for significant amount of money and reputation in governments seeking it.

Currently, there are 10 fleets, 8 defensive patroling 8 sectors in control of Sordahon Corporation and in SDH Home Sector that contains its own Headquarters and two planets, with one being colonized as resort world. There are also 2 rapid response fleets at back and call of CEO Sordahon and Chief of Security Division.

Normal Jump Drive allows shorter in sector distance jumps and jumping through various jump gates from remote location and using them as an exit point.

Jump Beacons allows jumping into other star systems without using a jump gate or prototype jump drive once set up and running by creating continuous jump tunnel of microscopic size.

Edit: Changed Year 800 into 840 and added Year 800 as the time seemed a bit short for such growth.
