Timeline (Fallout Supplement)
From D&D Wiki
17th century: 1697
- Sierra Army Depot is erected. Its mission is to store and maintain a defensive supply of military ordnance. This mission continued until 1991. This is a real event, before the Fallout universe diverged from ours.
- The Los Alamos Nuclear Research and Development facility, codename: the Reservation, completes construction. Los Alamos becomes part of the research team for the Manhattan Project.
- The Second World War comes to an end. Shortly after this, the Fallout Universe begins to diverge from ours, at first in minor respects, then major.
- May 5: Captain Carl Bell of the United States Space Agency (U.S.S.A.) became the first human in space. This claim is disputed by both the Soviet Union and China. Captain Bell's flight in Space Capsule Defiance 7 lasted twelve minutes and seven seconds, and made a full revolution around the Earth. Bell died when the capsule crashed on its return to Earth. 
- By this year, the United States is divided into thirteen commonwealths, each of which encompasses several states. The national flag is changed to reflect this and depicts thirteen stars - twelve in a circle and one in the middle.
- July 16: The Virgo II Lunar Lander Valiant 11 with U.S.S.A. astronauts Captain Richard Wade, Captain Mark Garris, and Captain Michael Hagen lands on the moon. The astronauts become the first humans to walk on a celestial body other than Earth. 
- The mission of Sierra Army Depot is changed. It is now responsible for the demilitarization of stores of surplus ammunition that have been deemed unfit or obsolete for military purposes. This mission is to be overseen by the Industrial Operations Command (I.O.C.) in cooperation with the Environmental Protection Agency (E.P.A.), providing a greener, cleaner way to dispose of military ordnance. This mission continued until 2050. 
- West Tek is founded
- The Delta IX rocket is commissioned by the U.S.S.A. The Delta IX rocket is the last of the manned rockets to the Moon. 
- The Delta IX rocket is converted for U.S. military purposes. Crew and instrument sections are replaced with a nuclear warhead. 
- The Mr. Handy series of robots is first brought to market as a general construction and maintenance unit by General Atomics International.
- Prometheus Coal, a division of Poseidon Energy, opens a coal mine in central Utah. A small village opens up nearby. It is called Eagle Rock
- An early bug in Mr. Handy robots that caused interference in the operation of the multiple arms is fixed with a hardware update, with no major problems since then.
- The Tibbets Prison is commandeered by the United States government in association with Vault-Tec and Poseidon Oil to tie into their Project Safehouse. On April 5, 2040, the Secretary of the Army makes the decision to build a new Disciplinary Barracks, with a capacity for 456 inmates. A cost ceiling of $363 million in allocated construction dollars is set. The target budget year for funding this project is fiscal year 2041. Construction begins in the Fall of 2042, with completion projected for the Fall of the year 2045.
- Doctor Morrison Rand was abducted by aliens when he was leaving the campus of Banfield College in Humboldt, Oregon some time after 10:00 p.m., on August 16, 2041.
- A major earthquake takes place in Mexico City. The Mr. Handy general construction robot becomes the leader in sales in Mexico.
- July: discussions with Vault-Tec to determine space and functional requirements for the new Tibbets facility.
- September 3: the Combined Arms Center Commander is given a decision brief of the USDB project, and selects one of three design options for further development. He also requests the Corps of Engineers to research an alternate location for the placement of this facility, since the geological evaluation of the site adjacent to the Trustee Unit revealed unsuitable subsurface conditions. Discussions involving the possible movement of the prison and relocation projects are also discussed, leading to the eventual three-rail system.
- The Great Passion Fruit Famine hits America. People actually notice the taste difference in Nuka-Cola when the flavor was changed.
- The X277 Viper Magnetic Rail Cannon developed for the U.S. Military by West-Tek is deemed too costly to produce on a mass scale and abandoned.
- The mission of Sierra Army Depot is changed again. It is refurbished with the latest in technology and is from now on used as a secret research installation for developing and testing robotic, biological and conventional weapons until 2076.
- Seeking to protect business interests and their oil supply, the United States begins to exert increasing pressure on Mexico, citing the political instability and pollution stemming from Mexico as a threat to the United States. Various economic sanctions serve to destabilize Mexico, and the United States military enters Mexico to keep the oil refineries running and making sure oil and fuel continue to make their way north across the border at Mexico's expense. 
- The N99 10mm Pistol becomes standard issue military sidearm following the phase out of the N80.
- A television documentary into the withered husk of the Texas oil fields brings the oil shortage into the American households, and reveals how deep the energy crisis runs. 
- April: The Resource Wars begin. Many smaller nations go bankrupt, and Europe, dependent on oil imports from the Middle East, responds to the Middle East's rising oil prices with military action. The long drawn-out war between the European Commonwealth and the Middle East begins. 
- May - July: The United Nations, already suffering, begins to collapse. In a series of heated debates, many nations withdraw from the organization as the U.N. tries to keep the peace. 
- July 27: The United Nations is officially disbanded. 
- The United States closes its borders to the flood of immigrants.
- The last manned mission to the moon occurs. 
- The widely known Nuka-Cola’s Dazzling Blue bottle color was adopted as standard after market research programs indicated that the blue color was the favorite in 86 people out of a hundred polled. 
- The socially transmitted "New Plague" arises, killing tens of thousands. The United States closes its borders and the first-ever national quarantine is declared. The source of the plague is unknown, but rumors persist that it is a genetically engineered weapon.
- ZAX 1.0 goes on-line, developed by Vault-Tec. Initially a prototype of some of the systems designed to govern the vaults, it is given to the government to help the Department of Energy collect resource data. Within a year, it is taken by the military for plague and tactical research; one version, ZAX 1.2 is constructed for West Tek (below).
- December: Like an exclamation mark on the end of a very bad year, a terrorist nuclear weapon destroys Tel Aviv.
- In light of the Euro-Middle Eastern conflict and the plague scare, the United States officially sets Project Safehouse in motion. The project, financed by junk bonds, is designed to create shelters, called Vaults, for the populace in the event of a nuclear war or deadly plague. Construction begins late in 2054 and proceeds rapidly due to advances in construction technology. 
- The West Tek Research Facility starts working on a new virus to kill the New Plague. Their viral research and close ties to the federal government eventually lead to them being chosen for the Pan-Immunity Virion Project twenty years later as well as Power Infantry Armor and laser research
- ZAX 1.2 is brought in to regulate conditions in West Tek. It is not part of the Vault-Tec preservation software, so it does not have any orders to protect humanity after the bombs fall. In the meantime, it calmly calculates data and plays chess with the scientists. Many scientists claim that ZAX is a "big ol' cheater" and draws the game out too much for a computer of his considerable abilities. 
- May: Uranium mining begins in Grand Canyon. Grand Canyon closed indefinitely.
- The Anchorage Front Line is established, as the United States increases its military presence in Alaska to protect its oil interests. The Anchorage Front Line causes tensions in the United States and Canada, as the United States attempts to pressure Canada into allowing American military units to guard the Alaskan pipeline. 
- The first artificial intelligence is born. Limited by memory constraints, its expansion is rapidly halted. The discovery paves the way for future A.I. research in laboratories throughout the United States. 
- Traffic on the streets of the world stops moving. Fuel becomes too precious to waste on automobiles, so alternatives are explored - electric and fusion cars begin to be manufactured, but factories can only make limited amounts while conserving fuel. The U.S. economy teeters on bankruptcy. Pressure on fusion research increases. 
- The Euro-Middle Eastern War ends as the oil fields in the Middle East run dry. There is no longer a goal in the conflict, and both sides are reduced almost to ruin. 
- The European Commonwealth dissolves into quarreling nation states, fighting over the remaining resources
- Many Mormon congregations come together to purchase places in Vault 70, located in Salt Lake City, Utah.
- August: The construction of most Vaults completed, except for Vault 13, whose construction finally gets off the ground...heralding a development cycle that seems plagued with problems. Drills begin in the other cities with completed Vaults, but the increasing frequency of the drills has a "cry wolf" effect, and the turnouts for drills trickle off as the years go on.
- Dr. Willem Clark, a top nuclear physicist in his day, is put in charge of all scientific endeavors at the Reservation. Colonel Green, a career soldier in the U.S. army, is put in charge of security.
- June: Due to enormous demands for electricity from a 17+ million population, a nuclear reactor in New York City goes supercritical during the summer of this year, almost causing a meltdown. The near meltdown brings into effect power rationing, and the term "Hot Summer" is used to refer to the New York incident. 
- August: Increasing need for mobility in the United States mechanized cavalry leads the military to focus the efforts on creating a man-based tank - essentially, a two-legged walking armored unit: Power Armor. 
- 2065 - 2067: Power Armor research grows and several prototypes are developed, many of which prove to be unworkable in the field. These prototypes pave the way for future advances in military, construction, and fusion technology. 
- The Reservation is given orders to research and produce nuclear missiles that can be fired from an orbiting space platform.
- Spring: As the oil resources dry up across the globe, China's fossil fuel dependency causes an energy crisis in the nation. China, bordering on collapse, becomes more aggressive in its trade talks with the United States. Unwilling to export oil to China, talks between the United States and China break down. 
- Summer: Adding further insult to the Sino-American relations, the first crude fusion cell is unveiled, one of the results of the Power Armor project. Devices designed for the fusion cell begin to be manufactured. Incorporating fusion power into the general U.S. infrastructure begins, but the process is too slow to supply power to the regions that need it. Nearly eleven years later, few sections of the United States were supplied with fusion power. 
- Winter: In the winter of 2066, China invades Alaska. The Anchorage Front Line becomes a true battleground.
- Winter: As a sign of increasing tension between the two countries, Canada proves reluctant to allow American troops on Canadian soil or allow American planes to fly over Canadian airspace. American and Canadian tensions rise, but Canada eventually backs down, and U.S. troops pass through Canada. This sets the stage for the Canadian annexation in 2076
- The U.S. Navy Missile Cruiser U.S.S. Ebon Atoll is accidentally sunk by the U.S. Navy Submarine U.S.S. Interference during the Anchorage Campaign. The Interference mistook the Ebon Atoll for an enemy vessel and shot it with a nuclear torpedo killing all on board. It is one of the worst U.S. Navy disasters since World War II. 
- Resource rationing in Denver causes riots. Midwest U.S.A. and Mexico start having food shortages and can't supply Denver with the food it needs. Food riots occur. National Guard called in.
- With more important things to spend their money on, Poseidon Energy closes the inefficient and dangerous Eagle Rock mine complex and sells it to the U.S. government.
- The first suit of T-45d Power Armor is deployed in Alaska. While lacking the full mobility of future versions, this Power Armor is incredibly effective against Chinese tanks and infantry. Its ability to carry heavy ordnance becomes key in various localized conflicts, and it has the power to destroy entire towns without endangering the wearer. China rushes to create its own versions, but they are many years behind the United States. 
- Senator Todd Peterson decides to build a secret bunker to house himself and his family should war break out. Senator Peterson is a wealthy man in his own right, but lacks the funds necessary for such a project. Through secret dealings with Poseidon Oil and a covert branch of the government known as the Enclave, the final funding for the project is attained. A construction site is chosen in southern Colorado and work begins.
- Canada begins to feel the pressure from the United States military as the U.S. draws upon Canadian resources for the war effort. Vast stretches of timberland are destroyed, and other resources in Canada are stretched to the breaking point. Many Americans refer to Canada as Little America, and Canadian protests are unheard.
- March: Vault 13 is finally completed - it is the last of the Vaults on the West Coast, and drills begin. Due to its late completion, the "cry wolf" effect that hurt the other Vaults is not as pronounced.
- December: Construction of Vault 106 and Vault 108 ends. Vault 108 was in construction for 8 years due to work stoppage.
- The first of the Chryslus Motors fusion-driven cars are developed. Reassuringly big and American, the limited models carry a hefty price tag but are sold out within days. Many Chryslus plants have long since been converted into making military ordnance. 
- The United States' increasing demand for Canadian resources causes protests and riots in several Canadian cities. An attempted sabotage of the Alaskan pipeline is all the military needs as an excuse to finalise its annexation of Canada, which had already begun in 2067.
- Completed B.O.M.B. missiles are sent to different space centers around the U.S. so they can be carried into space and installed into the B.O.M.B. satellites. The process is slow, but it is being carried out fairly regularly.
- August: The Ballistic Orbital Missile Base, or B.O.M.B.-001, is completed and partially functional (for security and maintenance bots) using a temporary onboard generator. The only thing the base needs are the manually inputted final launch instructions and codes, and the main power reactor.
- September 15: As China becomes increasingly aggressive with their use of biological weapons, the United States government felt that a countermeasure was needed. The Pan-Immunity Virion Project (PVP) is officially formed and plans are made to begin experiments at the WestTek research facility in Southern California.
- Negotiations between the U.S. and other world powers come to a dramatic end, with the President walking out of oil talks with the other world powers. After a much heated debate, the President stormed out of the meeting and declared that the last known supply of petroleum will be used exclusively by the U.S. and the U.S. will not sell or trade any oil to outside parties.
- Contrary to their claims of seeking only to retake Alaska from the Reds, American Power Armor units, infantry, and mechanized divisions are deployed to China, but they become bogged down on the mainland, putting a further drain on American resources and supply lines.
- Government decision makers order the dumping of radioactive waste into Eagle Rock's lower mines. Enclave politics help secure a contract for Poseidon Energy to develop and use their AGRICOLA mining robots in the operation of the dumping ground. Not surprisingly, the AGRICOLA lab turns out to be a pretty good bunker as well.
- July: The new Bloomfield Space Center completes construction. The facility’s first task is to complete the space rocket Hermes-13 to fly to B.O.M.B.-001 (originally slated for a Mars mission before new orders arrived). The mission: have the crew deliver and install the base’s main power reactor, manually enter final launch instructions, manual check for safety nets and protocols, and do a manual inspection of the station.
- The Sierra Army Depot A.I. (Skynet) becomes self-aware.
- RobCo Industries copyrights the Unified Operating System. This system is used for operating the Robco terminals. The copyright is renewed for each of the next two years.
- March 21: PVP experiments continue at West Tek with batch 10-011, in the wake of successful tests of the virus on single-celled organisms. Experiments on plant cells are postponed. The pan-immunity virion is renamed FEV - the Forced Evolutionary Virus.
- May 9: FEV experiments continue at West Tek with batch 10-011, in the wake of successful tests on flatworms, the flatworms exhibit increase size and heightened resistance to viral contagions. Experiments with insects have less success, and further experimentation on insects is postponed by Major Barnett.
- June 30: FEV experiments continue at West Tek with batch 10-011, with white mice as subjects. Increased size, muscle density, and intelligence are noted.
- November 9: FEV experimentation (batch 10-011) on rabbits is concluded. Increased size, intelligence, and (this time) aggressiveness is noted. Apparently, it was hard to determine whether the flatworms in the previous experiments were angrier and more violent than normal. Frankly, the researchers cannot be blamed for this.
- January 3: A military team under the command of Colonel Spindel is sent to the West Tek research facility to monitor the experiments in the interest of national security. Captain Roger Maxson (the grandfather of John Maxson, the High Elder of the Brotherhood of Steel in 2161) is among the team personnel.
- January 12: Splicing in several new gene sequences into their test virus, dogs are injected with batch 11-101a at West Tek. Although increased strength was noted, increased intelligence was not. Using batch 11-011, experiments are conducted on raccoons. Same results are noted, but the attempted escape of several infected raccoons causes Major Barnett to terminate the escape...and the test subjects. Two pairs of raccoons, however, are unaccounted for.
- January: The United States annexation of Canada is complete. Canadian protesters and rioters are shot on sight, and the Alaskan Pipeline swarms with American military units. Pictures of atrocities make their way to the United States, causing further unrest and protests.
- April 15: Once all secondary tests and studies are done on the test subjects, all dogs from the batch 11-101a FEV tests at West Tek are terminated...from a safe distance.
- June: Power Armor prototype completed, resulting in the T-51b Power Armor. This is the pinnacle of Power Armor technology before the Great War. Many of these units are sent to China, and they begin to carve a swath through the Chinese forces. The Chinese resources are strained to the breaking point, and the supply lines from the nations China has annexed begin to break down.
- August: Food and energy riots begin in major cities throughout the United States. Military units begin to be deployed in cities within the United States to contain rioters, and many temporary jails are constructed. A state of emergency is declared, and martial law soon follows.
- August: Hermes-13 & 14 space rockets are completed and await final funding and the orders to launch.
- October: Production of B.O.M.B. nuclear missiles is put on hold due to budget cuts. The reservation is put on reserve.
- October: Due to the seriousness of world events and the threat of nuclear war, Hermes rockets' launch is postponed while funds are routed to vault technology. Launch is rescheduled for 2077.
- October 4: At West Tek, fifteen chimpanzees are infected with batch 11-111. The most successful test to date, growth and immunities in the chimpanzees surpass all other subjects to date. The military practically drools over the results. Plans are made in secret to begin testing in small quarantine towns in North America, and the Mariposa Military Base construction is sped up in anticipation of moving the West Tek project to a location under military supervision.
- November: Enclave personnel seize control of Bloomfield Space Center and begin researching and developing a way to convert Hermes-13 into a personnel transport to transport important individuals off-planet.
- December: Fifteenth edition of Coping With Mr. Virus! is published by Vault-Tec.
- New Plague hits Denver. Rioters burned down large parts of the city in their fear of contamination and anger at their treatment. Many panicked and fled the city by car, clogging the freeways when they ran out of gas and trapping everyone behind them.
- January 7: Major Barnett orders transfer of all FEV research to the newly-constructed Mariposa Military Base, despite objections by the research team.
- January 22: The first domestic use of Power Armor within the United States for crowd and quarantine control. Units originally serving in China and the Anchorage Front Line find themselves fighting Americans at home. Food riots increase, and many civilians are killed. Several soldiers defect from the military both in Canada and the United States. They are captured, and are sent to military prisons.
- February: FEV Research is leaked to the world through an unknown source. Protests in many major cities and governments around the world, as well as accusations that the U.S. was responsible for the New Plague. FEV is seen as the threat it is, and serves only to fuel tensions. The governments of the world fear what the U.S. is up to. Speculating anything from trying to make a breed of super soldier, to trying to make Hitler's master race, they begin to panic.
- Prepared for a nuclear or biological attack from China, the President and the Enclave retreats to remote sections around the globe and make contingency plans for continuing the war.
- Between July 10 and October 23: Sierra Army Depot is evacuated.
- Sometime prior to August 15, General Constantine Chase, the hero of the Anchorage Reclamation, begins testing a virtual reality simulation of the Reclamation at the VSS Facility in Washington, D.C.
- September 6: Technicians at the VSS Facility notice General Chase is making radical, unrealistic changes to the Anchorage simulation. They believe Chase is becoming obsessed with the simulation and is gradually going insane, but refrain from confronting him out of fear that they will lose their jobs to military contractors.
- October 10: Captain Roger Maxson and his men discover that the scientists at Mariposa have been using "military volunteers" (military prisoners who didn't have their brains scooped for use in Brain Bots) as test subjects in their experiments. Morale in the base breaks down, and in light of the mental breakdown of Colonel Robert Spindel stationed at the base, Maxson's men turn to him for leadership.
- October 15: Colonel Spindel commits suicide. All scientists are executed.
- October 20: Captain Roger Maxson, now in control of Mariposa, declares himself to be in full desertion from the army (via radio)...and nothing happens.
- October 21: Maxson orders all families stationed outside the base moved inside the Mariposa facility.
- October 23: A pre Halloween costume show was going to be on later that day, called Freddy's Fear House of Scarlets. The preparations were made that morning.
- October 23: Nuka Cola Quantum is released to the public hours before the bombs are first dropped. Due to its late release, Quantum is now labeled a rare item.
- October 23: Great War: Bombs are launched; who struck first is unknown... and it is not even known if the bombs came from China or America. Other countries, seeing the missiles on their way, launch their planes and fire their warheads as well. Air raid sirens sound, but very few people go into vaults, thinking it is a false alarm. The Vaults are sealed. What ensues is two hours of nuclear bombardment upon the earth's surface. The effects are far worse than most imagined. The earth's faults shift violently. Mountain ranges thrust themselves through the soil. Whole lands are submerged under floods of water.
- October 23: Necropolis Vault never closes. Once it becomes known that the other vaults have sealed, people within Bakersfield attempt to force their way into Vault 12 to protect themselves and their families.
- October 23: The West Tek research facility is hit by warheads, breaking open the FEV tanks on levels four and five and releasing it into the atmosphere. Mutated by radiation, it loses its mutagenic abilities, but it later complicates things for the Master.
- October 23: The Mariposa Military Base survives, the soldiers and scientists within protected from the radiation and FEV flooding the wasteland.
- October 23: All Enclave personnel leave Bloomfield to either take cover or maintain "hot spots." Sub-reactor is turned off. Bloomfield, B.O.M.B.-001, and Hermes-13 & 14 are completely forgotten.
- October 25: Two days later at Mariposa, a scout in Power Armor (Platner) is sent out to get specific readings on the atmosphere. He reports no significant radiation in the area surrounding the facility.
- October 27: After burying the scientists in the wastes outside of Mariposa, the soldiers seal the military base, then head out into the desert, taking supplies and weapon schematics with them. Captain Maxson leads his men and families to the government bunker at Lost Hills. (This event was called the "Exodus," and the surviving soldiers went on to eventually form the Brotherhood of Steel.).
- October 30: A week after the initial blast, a black rain begins to fall. The source of the black rain was the massive amounts of radioactive particle debris (mainly soot) from the nuclear firestorm a week earlier. Plants and animals both go rapidly into extinction.
- November: Captain Maxson, his men, and their families, arrive at the Lost Hills bunker a few weeks later, suffering many casualties along the way, including Maxson's wife (but not his teenage son). The Lost Hills bunker becomes the HQ of the Brotherhood of Steel the Vault Dweller finds in Fallout 1.
- The dwellers of Vault 87 are locked in airtight chambers and exposed to the FEV by the Vault's Overseer and his security, who are simply, though callously, following the "plan" laid out by Vault-Tec. The vault's population are transformed into super mutants.
- The first effects of radiation are seen in the survivors. Widespread mutations occur with animals and humans alike. Those that survive the effects of the mutations are permanently changed. New species are created almost overnight.
- After four years of being trapped in the AGRICOLA lab, one of the two Poseidon scientists dies of natural illness.
- Five years after the Great War, some aspects of the world begin to calm down. Radiation and poison levels are still too high for normal human survival.
- Summer: The city of Necropolis founded by the ghoul survivors of Vault 12 (and the US citizens that fled to Bakersfield when the bombs fell).
- Spring: Set takes control of Necropolis, wrestling control from the original Overseer. The Vault 12 Overseer, not willing to take a dirtnap, is driven north and history loses sight of him.
- The planned date for the U.S. military to bring the VB-02 Vertibird, a Vertical Take Off and Landing (VTOL) aircraft, into service.
- After most of the initial survivors in the Reservation succumb to radiation, those "fortunate" enough to not die have turned into ghouls. And after spending ten years underground, they finally come back to the surface. Twelve ghouls, including Dr. Willem Clark, volunteer to search the wastes in the hopes of finding other survivors.
- Of the twelve volunteers to explore the wastes, only one comes back to the Reservation; Dr. Willem Clark. However, he has brought back a few dozen fellow ghouls to seek shelter at the reservation.
- After explaining the hardships and prejudices placed against ghouls by smooth skin humans, the ghouls of the Reservation proclaim Dr. Willem Clark as their leader. Willem further solidifies his place as leader by explaining his plans to one day make the ghouls the rightful and true heirs to the Promised Earth and that becoming a ghoul was the next, logical step in the evolutionary process.
- Vault 29 opens. Harold (currently human) sets out to make his fortune as a trader, making the circuit around the survivalist communities in the wasteland.
- Vault 8 opens, and they use their GECK to create fertile ground for their city. This eventually becomes Vault City.
- LA Vault opens, the Boneyard is founded and attracts survivors.
- Dr. Richard Moreau is exiled from Vault City for murder. The circumstances surrounding the murder are unknown, but he changes his last name to Grey and heads south.
- The Hub is founded by a man named Angus, who sets up camp around a filthy oasis in the desert, and he proceeds to begin trading with other settlements.
- Harold rises to the level of a caravan boss in the Hub. His caravans suffer occasional attacks in the wastes, but Harold's caravan outfit survives and prospers... until the mutant attacks begin to pick up a few years later.
- A man named Jonathan Faust leads his group of about 200 people from the overcrowded Vault 15 into the wastes of the outside. Eventually they become a raider band known as the Vipers.
- The Vault City Overseer retires and the Council of Citizens is established. The Council appoints the initial First Citizen.
- May 22: Increasing mutant attacks on Harold's caravans cause Harold to get so upset he finances one of the first adventuring parties of Fallout to try and find out where the mutants are coming from. Consulting with a scientist and doctor at the Hub, a man by the name of Grey, the two of them decide to join forces.
- June 23: Richard Grey's Expedition [including Harold] finds the Mariposa Military Base and the Expedition is scattered and defeated by mutants at the base. Grey is knocked into one of the vats of FEV by a robotic arm, and Harold is knocked unconscious, only to awaken later out in the wasteland.
- June 27: Harold, already mutating, is found by traders and taken back to the Hub. His former caravan partners and employees, horrified by his condition, abandon him and he is soon left.
- July: Richard Grey, now horribly mutated by the virus, crawls from the Vats covered with FEV and in terrible pain. Barely able to think or perceive his surroundings, he crawls into the Vat control room and begins his audio log. He fades in and out of consciousness, sometimes for days or weeks at a time.
- July-November: Richard Grey begins to acclimate to his condition, and begins his first tests of animals by exposing them to FEV. These experiments and his growing awareness lay the foundation for his plans for the Unity and the master race. He takes the name, "the Master.".
- November: The first human victim wanders into Mariposa, and Grey consumes him.
- December: Grey continues his experiments on wanderers that enter Mariposa... with no success. The creations are flawed (due to the radiation counts in their bodies), making them big but incredibly stupid, and Grey consumes them rather than letting them live.
- January: The Master discovers the problem with the influence of radiation on his mutations, and he begins to choose his subjects more carefully. The first classic super mutants are born. He begins his plans to build an army.
- 2103-2130: Throughout this period, the Master begins slowly gathering test subjects, willing or unwilling, from local human stock. The Great Winter of 2130 and the scarcity of human subjects make building his army difficult.
- The Vipers' attempt to raid the Hub is stopped almost solely by Angus. Angus' defense causes the Vipers to retreat north
- Winter: Angus is murdered. Hub is thrown into chaos.
- A band of merchants seizes the water tower in the Hub. They demand anyone wanting water must pay a toll. The Great Merchant Wars begin.
- 2126-2128: The Great Merchant Wars are fought, the Water Merchants seal up the town, but are outnumbered.
- A man named Roy Greene (Justin Greene's grandfather) makes the peace in the Hub and negotiates a settlement. The Hub's Central Council is formed, composed of two representatives from each of the Hub caravan companies. A long period of indecisiveness and meetings maintain the status quo in the Hub.
- The Great Winter occurs.
- 2131-2135: The Master begins ordering his super mutants to gather human stock from caravans. For many years, the caravan disappearances are blamed on monsters in the desert, and even when the abductions begin to occur on Hub caravans, the deathclaws are blamed. The super mutant army grows.
- A faction within the Brotherhood of Steel led by Sergeant Dennis Allen gains strength, and they urge the Elders to let them explore the southeast Glow for artifacts. The Elders refuse, so Allen and his divisionist group splits away from the Brotherhood of Steel, taking some technology and weapons with them.
- Led by Sergeant Dennis Allen, a small team of the Brotherhood of Steel head to the West Tek research facility in search of technological artifacts. They arrive there twenty days later, and are promptly chewed apart by the West Tek's unforgiving automated defense systems. Wounded, Allen begins to suffer radiation poisoning from a leak in his suit. Before he dies, he logs what happened to the expedition into a holodisk then goes to join the Brotherhood in the sky.
- Elder Roger Maxson dies of cancer, and his son, already an accomplished soldier, takes up the role of "General" (Elder) within the Brotherhood of Steel. John Maxson becomes a member of the Paladins, showing tremendous promise as a soldier.
- The Jackals lose a major battle against rival raider clan The Khans, survivors are forced further east.
- The Master begins to mass-produce super mutants. Only about one in six or one in five attempts are successful, and of these successes, only half seem to last to go on to be part of his growing army, called the Unity.
- Spring: Vault 15 opened.
- Vault Dweller born.
- Winter: Raiders begin to form in the region as food supplies run low. The Khans and the Vipers begin terrorizing local settlements.
- Around the early 2150s the Vipers recover from their defeat by Angus at the Hub, replenish their ranks from captured slaves and caravan drivers, and begin to establish a power base in the badlands to the North of the Hub (and south of the Lost Hills Bunker). Driven by a religious frenzy (and the need to provide for their much larger numbers of soldiers and disciples), they begin raiding more frequently than before, attracting the attention of the Brotherhood of Steel.
- As their influence slowly spreads throughout the wastes, the Master finds humans, doomsday cultists, and rather than dip them in the vats, he demands their obedience as spies - their leader is a man named Morpheus, an ex-member of the gang called the Rippers, and he pledges his followers to the Master. Morpheus and his cultists form the future core of the Children of the Cathedral.
- The Brotherhood sends out a few squads of scouts to track the Vipers down - it is more of a training exercise conducted by John Maxson's father, as the Brotherhood is convinced that small detachment of troops in Power Armor would be sufficient to deal with a group of raiders, no matter how large. One Brotherhood squad, lead by Maxson, finds the Vipers. Expecting the raiders to break and run, Maxson doesn't take into account the religious ferocity of the Vipers (or their poisoned weapons), and when a single arrow nicks him with his helmet off, he dies within hours. John Maxson takes up the role of Elder, and Rhombus becomes the new head of the Paladins.
- The Paladins, now led by Rhombus, begin a full scale campaign against the Vipers, tracking them down and wiping out almost all of their members within the span of a month. Some of the Vipers are able to flee north and east into the mountain range.

Within the Vault, the Master begins to send out patrols to Vault locations in search of these other Vaults.
- The Master sees advantages in establishing a benevolent "religion" (the Children of the Cathedral), and using them as spies in settlements throughout the wastes. Missionaries from the Children of the Cathedral spread slowly across the wasteland, acting as eyes and ears for Morpheus and the Master.
- The Master learns the location of the Bakersfield Vault, Vault 12, and sends a detachment of super mutants there to seize the vault. Many ghouls are snapped like twigs in the attack, and Set finally parleys with the super mutants, telling them that the ghouls are the Vault survivors the super mutants are looking for. The super mutants, angered at failing to find an intact Vault, set up a small garrison at the watershed to watch the inhabitants and ensure Set's... cooperation in the war to come.

- 2236-2238: Horrigan gradually mutates from exposure to FEV, gaining the physique and slow, stupid, single-mindedness of a super mutant. He is kept heavily sedated, operated on, and studied. He is conscious for only brief periods at a time, then quickly sedated after the bloodshed is over.
- January: The Enclave, having obtained the FEV data, abandons the Military Base site after more mutations occur, causing 2nd Generation Super Mutants to arise - the Enclave leaves a single squad behind to wipe out the super mutants, but the mutants, using armaments they have cached in the base during excavation, reduce the squad to ashes after suffering heavy casualties.

They were caught by NCR and ended up "blowing" the vault and totally ruining the future ability to settle the payment problems in the area (exact circumstances are unknown, Porter's group didn't actually steal the money, but it's gone nonetheless). Captured, sold out by Spineless Stan Lowery (a man in the 370 team who didn't participate in the raid because he was afraid they'd be killed trying).

Gov Dodge (Dodge hoped that Porter will loop back to pick up the money from the blown vault, but the escape he arranged only resulted in the 308th getting free, not the 370th, and since Porter didn't steal the vault money anyway he wouldn't know where to find it).
