Hello everyone and welcome to the first prologue/timeline of Xcom: Human incursion! This takes inspiration from various titles in the Xcom/Mass Effect category, namely from the author Timedraven. If you want writing actually worth your time, go visit him, he's got some pretty good stories. Forgive me, I'm not the best writer ever so please; forgive me if I make a few mistakes. Reviews of any kind are welcome and I love reading your guy's feedback on my work so I can improve and become even better. This also takes a little inspiration from my other works such as Xcom: Ethereal Ally and other thoughts I haven't gotten down on paper or computer yet. I am incorporating other series such as Civilization: Beyond Earth, mostly because it doesn't get the attention it really deserves. I may add more later but we'll have to see, you may recommend other series in the reviews or PM and I'll look into it. But that's enough of me talking; I don't own anything really important so you wouldn't want to sue me.

50,000 years ago- Remaining Prothean scientists salvage a wrecked ship near Ilos and activate it. The Protheans then develop a massive bomb which would be used to blow the Reapers in dark space out of existence. Before the Protheans could get to the dark space via Citadel, Sovereign appeared, noticing the Prothean presence. It then proceeded to destroy the Prothean ship before it could reach dark space. In a blaze of vengeance however, the Protheans activated the bomb. Sovereign attempted to protect the Citadel and in doing so, saved the Citadel and caused severe damage himself. The Citadel however, was knocked deeply off its axis and into space.

Human timeline told from Human Codex, dated in Earth Time.

1962 January 9th- First contact with the 'Zudjari' is made. Zudjari invasion of the United States and various other countries in Africa and Asia begins. All attempts to contact the invaders have thus far failed. The Xcom project is activated.

1962 January 12th- Zudjari presence on Earth is confirmed by multiple countries including the United States of America. The world goes into chaos as riots begin in Rural and Urban areas, as the Zudjari threat grows.

1962 January 20th- As riots grow in violence, Spanish police open fire on protesting civilians in Madrid. The incident is dubbed 'The Madrid incidente.' This action throws the country in pandemonium and brings the already teetering country on the brink of a massive civil war. Meanwhile, the Zudjari now control a significant amount of land in Thailand, Sudan and southern Florida.

1962 February 10th- Some poor and rural countries are now engaged in all out civil wars. Zudjari forces spread out and forces now dip into Vietnam. Zudjari forces attempt to reach out into southern Chinese lands but are harshly pushed back. Saudi Arabia invades Oman and Yemen but the actions go largely ignored as countries everywhere are caught up in their own problems.

1962 February 21st- American and Xcom's combined forces, in desperation launch 'Operation Silent Blade' to retake the Floridian mainland. Not expecting a counter attack of this magnitude from the Humans, Zudjari forces are caught by surprise and it's a Zudjari massacre as several strongholds are re-taken and several Zudjari are captured for autopsies and interrogations as well as several intact weapons are retrieved. Encouraged by this change of events in the west, a combination of what was left of the Thailand armed forces and the Chinese army storm the Zudjari bases of operations. Several hundred 'sleep walkers' are retrieved for scientists. It is to be noted that sprawling Alien structures have been planted into the ground by the Zudjari and have been terraforming the Earth's surface. Such structures are quickly targeted by Human air raids.

1962 March 14th- The first Laser rifle porotypes are tested in the field and results in large satisfactory among the Human Armed Forces. Many exchanges have been passed between the Zudjari and Human forces, resulting in varied results of victory and defeat. Soviet and Chinese scientists find success in reverse engineering Alien craft.

1962 May 1st- Zudjari forces are pushed back considerably by now but so are Human forces across the globe with Xcom's aggressive, risky and daring moves leading the charge. Sudan however has been completely engulfed by Zudjari forces and is threating to tip over into Ethiopia, Egypt, Chad as well as various other countries in Africa. Central and Northern Africa has become a near impenetrable Zudjari stronghold. Many Humans however still remain in Africa leading a strong guerilla war against the invaders. At the helm of the guerilla war is Amare Ajanlekoko, a now renowned African hero for his bravery and valor. Guerilla fighters led by Amare continuously harass Zudjari forces whilst raiding several Zudjari bases.

1962 July 9th- Zudjari forces in America have been completely destroyed and pushed back to their home world using a "'wormhole' of sorts" As described by one scientist. Zudjari forces begin to retreat from Asia as reverse engineered alien ships piloted by Humans start to roam Chinese and Soviet borders. Other countries ask China and Soviet Union for this technology but the two communist nations refuse, rather keeping the upper hand over their Human rivals.

1962 September 2nd- Zudjari armed forces are now completely destroyed or captured in Asia. But as the Zudjari 'wormhole' closes, several hundred Zudjari are left untended by their 'Mosaic' and without guidance, go either completely insane or give up and lay down arms, surrendering to the Humans. Zudjari refugee camps pop up all over China and northern Thailand. These 'Refugee camps' are secretly used as labor camps by the Chinese to expand their work force.

1962 September 4th- The US begins project 'Starscape' in case of another Alien invasion.

1962 November 18th- NATO forces move into Northern Africa to wipe up Zudjari populations. The Soviet Union and China do not comment on this. NATO and African guerilla fighters encounter each other and plan together in secret on a major counter attack.

1962 December 21st- Zudjari forces are pushed back severely due to a major counter attack by Human forces.

1962 December 24nd- The world is in utter shock as a nuclear missile is dropped on the former Sudan capitol. No comment on who launched the nuke but many suspect the Soviet Union as the culprits, further heightening the cold war's severity.

1962 December 25th (Christmas) - All Zudjari forces in Africa surrender. The last remains of the Zudjari in various other parts of the world give up as well. The Zudjari population is facing an uncertain future as protests to outright kill the rest of the Zudjari rise and many protests turn violent.

1963 November 21st- The decision to destroy all Zudjari weaponry (While keeping the few civil benefits) falls through as China and the Soviet Union back out of the agreement. All other major powers sign the agreement however. China and the Soviet Union urge several 3rd world countries in Asia to back out of the agreement and succeed. America and her allies begin to work on the alien tech in secret.

1979 April 27th- The 'Pan Asian Alliance' is born, bringing all of Asia together for the first time. Zudjari are now accepted as second and third class citizens as their populations on Earth rise with their genetically enhanced fast re-production system.

1979 October 7th- South America (And countries 'below' Mexico) unite to form the 'South American coalition' where notably, the Zudjari population is lowest. The South American Coalition is severely anti-Zudjari and their government quickly follows in the path of fascism. Many historians compare these actions to the rise of the Nazis. This is followed by the creation of the European commonwealth and North American Council.

1980 January 12th- The South American Coalition, Pan Asian Alliance, European commonwealth, North American Council and the Soviet Union are embroiled in war which is later called WWIII. With the Pan Asian Alliance's advanced weapons, they quickly seize the upper hand with the North American Council not far behind. Africa is left alone through the war.

1985 September 5th- The African Federation is formed and the several super powers in the war try to win Africa's favor. None succeed. The Soviet Union and the Pan Asian Coalition announce their alliance.

1987 January 12th- WWIII ends with human casualties over 1.5 billion and Zudjari casualties over 500,000, half their population. The war ends in a stalemate across the board with 3 nuclear weapons having been dropped in the European Commonwealth (Poland), Pan Asian Alliance (China) and the North American Alliance (Canada).

1990 January 1st- The UN is disbanded and 'The Council' is put in place. Due to popular demand, the Council is more militaristic than the UN was and is prepared incase another war, Human vs Human or Human vs alien.

1993 March 18th- A Zudjari ship is discovered by Xcom orbiting Earth. The ship quickly self-destructs before Human forces can arrive. Conspiracy theorists however claim that the Americans captured he ship and brought it to Earth to study.

1996 October 11th- The Soviet Union is able to sustain itself because of its advanced mining operation in the asteroid belt.

2000 June 30th- As the Earth's population grows, a moon base is established at the same time as the ISS (International Space Station). The Base's population quickly reaches the hundreds.

2009 April 6th- Amare Ajanlekoko dies of natural causes. He is proclaimed a hero.

2014 March 12th- The Moon base is fully operational and a small city resides on the Moon's 'Bright' side. People can see the city's lights from the Earth surface. As the world's population starts to regain its pre-war status, the world is going to once again be embroiled in war.

2015 February 11th- The Ethereal invasion starts with all the force of an avalanche. The Ethereals strike in Munich, Germany, European commonwealth. At first, the sudden attack is thought to be a terrorist attack. Soon though, an alien ship enters Commonwealth air space and strikes the city with plasma strikes. By the time the Nation's militia is able to arrive, it's an all-out war scene with local police fighting valiantly against the invading forces. When the militia arrives though, the aliens are beaten back and defeated. Several autopsies are conducted and all available technology is salvaged for the Human and Zudjari's own purposes. While the Ethereals own technology is only slightly more advanced, all useful technology is immediately put to use, including designs for an 'Arc Thrower' used to capture enemy combatants.

2015 February 12th- Another attack occurs in Chicago, USA, North American Council. The attack is even more severe and the city is leveled by the time the army can get there. The Xcom project is re-activated.

2015 February 13th- The ISS goes dark. It is later found, destroyed and in utter ruin. The Moon base is put on high alert and the small militia there grows.

2015 February 31st- Ethereal attacks occur in rapid succession with an average of an attack every day. So far the attacks have been sustainable by Human militaries but with every attack, the enemy seemingly gets stronger, despite heavy casualties on their side. Scientists theorize that they use clones to sustain their army size.

2015 March 5th- Project 'Starscape' is completed by the North American Council. The world watches in amazement as what is now known as the one (And to this date only) mothership class leaving orbit from Earth. It's named the 'Eternal Pride.' The ship is equipped with state of the art stealth systems and fly's right under the Ethereals noses and towards space at 10x the speed of light (FTL). This great achievement is accomplished using [CLASSIFIED] as the main power source. After the launch, all evidence is erased of project Starscape and all data regarding FTL travel is destroyed, in fear of it landing in hostile hands. Namely, other Human spies.

2015 June 29th- Conditions on Earth worsen as the Ethereals almost completely destroy the Moon base. The same day, the Eternal Pride arrives out of FTL and lands on the world 'Terra Nova.' Colonization begins immediately with its 20,000 occupants.

2015 Septmer1st- Plasma weapons are perfected and the tide is turned against the Ethereals as Humans and Zudjari are now able to level the playing field. In other news, the new Terra Nova colony, named 'New London' is a major success and they begin to prosper in technology, health and education.

2015 October 9th- 'Psionics' is discovered among humans. It is estimated that every one in three Humans are Psionic positive. Zudjari are tested as well but scans come out empty. Although Psionic scanning has found an equally powerful ability among Zudjari. This new skill is more physical than mental and is called 'physici potentia'. It estimated that every one in three Zudjari are Physici positive. These new found powers help push back the Ethereal threat.

2016 April 14th- The Ethereal 'Temple Ship' is destroyed with help from the 'Volunteer' who was proclaimed KIA, leading the Temple ship into space so it wouldn't destroy Earth in a black hole. The troops that survived the massive counter offensive remember the Uber Ethereal's threat of a greater foe. Militarization is top priory among the people of Earth. With the temple ship destroyed and without an Uber Ethereal to follow most Alien forces surrender, thus creating need for refugee camps. An increase of Psionics is a direct result of the Temple ship's destruction over Earth, resulting in 60% of Earth's population becoming Psionic potential.

2016 April 16th- Riots and protests begin immediately in light of helping these new aliens. Some people fear another Madrid incident occurring.

2016 June 19th- The final death count for the Ethereal war come into light of the public. 1 Billion People lost, 70% were civilians. The general populace is outraged, more so than when the death counts for WWIII were revealed.

2018 March 8th- Zudjari are now generally recognized as first class citizens, equal to humans. Ethereal species still remain a lower class.

2019 25th- Plans to restore the Moon Base are underway and it is expected to take several years to restore the damage. Plans to launch the first manned mission to Mars now seem in reach and the first mission to mars is scheduled for 2025.

2023 February 1st- The Moon Base is back to how it had been before Ethereal attack. A plan for a 'Construction Yard' is put forth. The station's primary function will be to build ships. It will also have built in lasers to protect itself.

2023 May 9th- Terra Nova now has a populace of over 40,000. The infrastructure is built and city lights can be seen from orbit. Terra Nova citizens have a life expectancy of over 100 years. Mining operations of the Terra Novan moon are commencing and the technology, epically in synthetics and the planet itself are going smoothly. Construction of a space station in orbit of the planet is also underway.

2025 December 11th- The first manned mission to Mars commences. Using salvaged Alien technology from both the Zudjari and Ethereal, the flight will take only a day.

2025 December 12th- The first manned mission to Mars is successful and the astronauts composing of five men and women and five Zudjari are safe. They will depart to come back to Earth shortly.

2026 November 17th- The Terra Novan colonists make an astounding breakthrough. The first true AI is developed. The AI boots up for the first time and the Terra Novan people ask if it 'Feels okay.' After a short while, it responds. 'I am… fine.' The people rejoice until the AI asks a question back at the colonists. 'Am I alive?' This is answered in; 'We don't know yet but we consider you alive.' The AI is sufficed with this response. Over the time, the AI decided to call itself 'primum' which means 'First' in Latin. Primum takes on the avatar of a middle aged woman.

2027 February 22nd- The first Martian colony is founded. The small settlement soon grow as colonists on Earth leave their now resource less planet.

2029 July 17th- The Earth construction yard is finished. In the coming years, the yard will be used as a major industrial hub.

2030 October 9th- Scientists on Terra Nova make an incredible breakthrough in that their planet itself is alive. By now, several AIs exist and the two ideologies, Synthetics and preserving the planet clash furiously, creating much unrest.

2035 May 30th- In a direct result of political unrest and ideologies, two major factions are created on Terra Nova, The Synthetics and the Planetary Union. Almost instantaneously, war breaks out globally. Giant mechanical machines are created by the Synthetics while gene fusing and taming the local wildlife are the Planetary Union's top priority. Soon, Planetary Union troops can wade through the planet's dangerous miasma while Synthetic troops are all but destroyed in the toxin. All thoughts of their home world are forgotten as the war rages on. The Planetary Union teaches their young that Terra Nova is their new home world while the Synthetics are too busy at the moment with war planning.

2040 January 11th- The Terra Novan war comes to an end with the Synthetics winning. What's left of the Planetary Union is banished to deep space, never to be seen again. It should be noted that humans without synthetic implants or planetary gene moding are allowed to stay.

2040 November 23rd- The Martian colony is now able to sustain itself with over 600,000 occupants.

2046 September 8th- Prothean ruins are discovered on Mars. The archives are surprisingly in good condition and translation of the archives begins immediately. Two things are discovered almost immediately: That the ruins are from a race called Protheans and that there is a Mass relay in the system, which is Pluto's moon, Charon. Human unification is proposed.

2050 January 1st- The Charon Mass Relay is activated from outside the system. From the relay comes a large fleet of ships. A similarly large amount of ships from the Humans and Zudjari coalition meets the new ships. They appear peaceful and negotiations begin as one of the Alien ship's docks with the Earth Construction Yard. They reveal themselves as a species called the 'Volm'. Their species is on verge of extinction from a greater power called the 'Espheni'. Peace is established and the Volm Empire integrates itself in Human society-slowly. Volm are to this date, the only species to have peacefully integrated themselves into Human society. Some Volm still live in their ships to this day though many now live planet side.

2056 January 1st- Human Unification takes place with all of the Human leaders stepping down and forming what is now known as the 'Species Alliance'. With this, all Species Alliance controlled colonies now have the right to govern themselves how they see fit, using the USA's states as an example. All Alien species inside the Alliance are now considered equal to Humans, including Ethereal. Historians remember the 'Eternal Pride' launching from Earth orbit and the Alliance, not knowing that the Synthetics exist, probes are launched to find the missing colonists.

2059 June 11th- The Synthetic colonists on Terra Nova send out probes to search for Earth, for they forget where the location of Earth was.

2060 April 19th- The 'Espheni war' begins. It begins with the Espheni emerging from the Charon Mass Relay in gigantic 3km long ships, firing automatically on Species Alliance ships that were stationed at the Charon Mass Relay. Volm fight alongside Human, Zudjari and Ethereal forces, much to the rest of the Species Alliance's surprise. They had assumed that the Volm would sit back and allow the rest of the coalition take on the Espheni. They were wrong when several Volm ships traveled from Earth to assist in the fight. The tide was soon turned against the Espheni and they were forces to retreat into the relay. Several dog fights take place near the relay after this with Species Alliance forces holding their ground. Xcom remained inactive throughout the war.

2063 June 15th- The last Espheni attack at the relay. After this, there now are no more Espheni attacks, many speculate that they gave up and that the Alliance wasn't worth the ships they lost.

2078 November 11th- A Species Alliance probe comes into contact with a Synthetic probe. Curious, the two powers soon travel to their individual probes. They come into contact with each other and exchange knowledge. Negotiations are to begin immediately.

2078 November 13th- Negotiations take place with the Synthetics and Species Alliance. With the help from Synthetic AIs and Species Alliance technology, the spaces in between the two powers are mapped and every Garden world is set for immediate colonization. For protection, the Synthetics integrate into the Species Alliance, making one Humanity.

2078 December 30th- With the help from Synthetic engineers, a Species Alliance ship is able to achieve 'Hyper Space'. All ships are planned to be outfitted with this new technology as it is far more convenient and sophisticated than their past FTL drives and Mass Relays. All Mass Relays are scheduled for immediate break down for resources.

2100 January 1st- Humanity slowly spreads out among the stars with help from AIs, Hyper Space drives and other integrated species. The Alliance celebrates the new century. Volm are finally tested for Psionics and Physici. Volm only have a slight potential for Physici but not Psionics. To this date, only Humans and some Ethereal races can master Psionics.

2109 July 10th- On a scouting mission at the Eden mass relay, first contact is made with the 'Turians'.

Oh my god, I finally finished the timeline! This took several (stressful) days to complete. Yes, this is also a crossover with Falling Skies and Civilization. If you want me to include other series in this fic, you can PM me or review the series and I'll look into it. I can't guarantee everyone's series will be in though. In this fic, the Council has only discovered a little, little piece of the galaxy as in the Relay network doesn't stretch the entire galaxy. At most because I find exploring an entire galaxy a process that takes many, many, many, more years. On another note, this isn't a 'Humanity crushes all' fic because even with Vast amounts of technological superiority, Humanity simply doesn't have enough ships or people to take the entire Turians out. And remember, the Reapers are coming! Though I won't focus on them as much as other fics because I have my own original Villain the galaxy has to worry about.

Edit: (12/30/2015) fixed some grammar issues that had thrown off some people in the reviews. Also added a few more things that explained on stuff, example: Why they destroyed all FTL knowledge and data.

Edit: (11/11/16) Fixed many, many things
