SCP:FF Complete Timeline

This is the complete timeline of the SCP: FF universe. Feel free to add important dates and events.
== 2000 B.C. ==
Since the dawn of time, creation, and everything in between, God had tasked the archangel Uriel to guard the gates of the Garden of Eden.
The garden was God's gift for those in the afterlife. Those with good spirit and had lived their lives to their fullest would be given the gift that would be called their new home. Before then, the garden was a paradise that belonged to God. It's not known where it was located, but within the garden were various plants and animals, fruit and other varieties of life that filled the land in a beautiful view.
After Adam and Eve ate the forbidden fruit from the tree of life, Uriel guarded the gates with his flaming sword; rivaling that of the temperature of the sun, denying access to anyone that wished to enter. Anyone that came into contact with him were telepathically directed to "forget," automatically obeying his command, forgetting everything that ever happened, and having no memory of contact whatsoever.
However, if anyone interrogated him, or came within at least a kilometer of him, they would be reduced to smithereens by his sword.
He didn't mean any harm by this; he was just guarding the gates by any means necessary. He would continue guarding the gates for millennia; never moving from his spot, standing tall, proud and triumphant. This went on to the present day.
== 1300’s ==
1348 - In the 14th Century, France, Europe, the Black Death was spreading like wildfire. People all over Europe were infected, no remedies or medicine to help treat the public. It was a gruesome sight.
Of the many plague doctors that were available in the country, Dr. Bartholomew Artz, one of the finest physicians in all of France, had spent 2 years treating patients with the disease, that he gave up in search of a cure.
Traveling through all of Europe, he was determined to rid the world of the pestilence. Over time he began to realize that there was nothing that he could do to help others that were in need. People began dying one by one, and soon whole populations of towns and cities had been claimed by the pestilence. He soon learned that he was immune to the disease, although he couldn't understand how or why this was to be. The most logical explanation was genetics. 
He became infatuated with his work; his desire to find something, anything to help remedy the disease that only he could see. But in reality, he was lost. He had spent years of experimenting that he mistook his profession for his identity. The "experiments" in question resulted in reanimated corpses of people and animals that were hostile.
This was the work of Dr. Artz. A man who wasn't really a man anymore. He was a doctor. He was the only one of his kind. Through time, his body began to attach itself to his clothes; his arms, legs, and even the mask he wore became his face. His outfit became his new body. This was something else he wouldn't understand either. Regardless, he carried on with his mission.
== 1800’s ==
1808 - Legends in Greek mythology states that Hephaestus, the God of blacksmithery and other talents, who was the forger for the Greek Gods was petitioned by Zeus to create a gift for the Muse Melpomene. Melpomene, at the time, was the muse of chorus who's songs were breathtaking and beautiful. It was so magnificent that it soothed souls from the bodies of mortals and Gods alike, sending them to far off lands and back again.
One day, she did not sing. The only notes that left her lips were that of tragedy. True to her sisters as well, this left Thalia with an idea. The muse of comedy and daughter of Mnemosyne and Zeus used this opportunity to make a mark on Melpomene's legacy. So Hephaestus used her laughter to forge a mask, giving it the name "Dyo Polonoi," which meant "Of two poles."
Centuries following the fall of the Greek Empire and the crusades, the mask was forgotten in a heavy fog, along with the memories of the Titans that forged him to be.
With no name and origin, it was later found by Bartholomew in the Middle East, who had traveled far from home in his quest to rid the world of the pestilence.
Upon examination, he saw it's abilities that would make it useful for his research. During their time together, they became good friends. The mask would aid him in his experiments; it's abilities to posses a host whenever worn, overall manipulative and "charming" behavior, and rapid decomposition of hosts whenever worn. The mask would secrete corrosive black liquid, with no source of the substance being found.
Their company wouldn't last long, as it would be forgotten in Venice; for it wanted to explore the world, and find a new host to live in. The two friends departed to go their separate ways. 
1883 - In 1883, Lord Blackwood and several other men were on the hunt for a creature that threatened the lives of many in Provence, France; The Tarasque. The Tarasque was a creature of legend amongst the town of Provence. Although the creature in myth was described differently compared to what witnesses saw, it was a beast nevertheless. The creature was ginormous, had a reptilian-like emaciated appearance, and rumored to have regenerative abilities. Something no one had ever heard of before.
Eventually, Blackwood and the men successfully subdued the creature, and brought in it's remains for their reward. However, the day they brought in the creature's remains into Avignon with their prize, it reanimated; bringing itself back to life as if by magic. It was a horrifying scene.
Bombs were dropped onto the city as a last resort to finish off the Tarasque for good. When the survivors rose from their vaults, they learned that at least 10,000 people had been incinerated by the flames, and all of Avignon had been destroyed. The creature was nowhere to be found. When Blackwood returned home, he received a letter informing him of a questioning that needed his matter held by an organization called "The SCP Foundation."
The Foundation was created to Secure, Contain and Protect the world from anomalous phenomena, the paranormal, and everything in between. In time, the foundation would grow, expanding to a global organization, catching the attention of numerous groups of interest that either aided the foundation or contributed to the anomalous phenomenon.
Doing so, they hid themselves from public view; not wanting anyone to know about their existence due to the various anomalous activity already present in the world. With this, the SCP Foundation was born. And it was about to get bigger.
== 1900’s ==
1915 - During World War I, Charles Lawrence served in the military as a Corporal Officer fighting for the country.
Lawrence wasn't a simple man; he was mentally unstable. He wouldn't keep up with his hygiene, he'd often stare at his bunk mates in their sleep, and would occasionally laugh to himself. Although he didn't have many friends, he carried on like nothing mattered.
He and fourteen men were sent to the German trench, going out into no man's land to see what they could find. Among the gruesome sight of mutilated corpses laid throughout the trench, there was a hole with black ooze that no one ever saw before. Lawrence, being the brave volunteer, went in head first, lasting 2 minutes in the mucus-like substance before climbing out.
When the men rushed back to the trench, the Corporal was questioned in the incident. He began loosing his sanity days after falling into the hole with the black ooze. The substance was corrosive, and burned to the touch. After being hospitalized, he was then sent to a French mental ward, where symptoms began to take over his body. It wasn't until one November night that he and eighteen men went missing, only for him to return several days later as a zombie.
From the first time he dove into the hole, Lawrence became immortal; his skin rotted off, the substance coating his entire body, with his worn-esc war attire still intact. He could teleport anywhere with his abilities, corroding and melting everything he touched like acid. After breaking out of the mental institute, he went into hiding within the bomb-riddled towns of Europe. Waiting. Preying. For his next victim.
1978 - In 1978, one of several groups of interest known as "Children of the Scarlet King," kidnapped seven young girls and performed satanic sexual rituals on them; impregnating them.
The cult used a warehouse for their hideout, until a police raid brought it all down, rescuing the seven girls. Unaware of the rituals that took place prior to the investigation, one of the girls went into labor 24 hours later, giving birth to a hideous creature that resulted in several dozen casualties. Foundation Personnel that were at the scene took the rest of the girls into custody, as well as the evidence retrieved from the police. One of these items was a notebook that belonged to one of the cult members.
The contents of the notebook gave background on the organization. The Children of the Scarlet King was a cult that worshiped an entity simply known as "The Scarlet King."
The king, or "Khahrahk," was an entity that was born from the Tree of Knowledge when it was planted by God. Smaller than his brothers and sisters, he remained in his fortress of solitude; the abyss. He felt pain and loneliness, and blinded by his emotion, he came to realize that existence was pain. He consumed his brothers and sisters, growing stronger from their power that they once held.
The stronger he grew, the more spiteful he became. He cursed creation and it's creator, vowing to destroy the tree and all of it's branches and roots. He fought the light so others could live in darkness. He came out on top; took the throne, and all the other gods that were born within the same place either died, left, or had submit to him. With no more competition, he declared himself the King of Darkness, and carried on with his agenda.
He waged war on creation, created a kingdom of his own, and slept with one of his subjugations; Sanna. Sanna was wise and beautiful, and was one of the many gods that bowed before the king. For seven days and seven nights, he slept with her, bearing seven children in total before her death. From then on, he was known as The Scarlet King. As for the seven children, they were all turned into his brides. Each bride was given a seal so they couldn't die unlike their mother. Each bride gave birth to their own children; warriors. Monsters. Abominations that would contribute to the war.
Aside from origins, there were instructions written in the notebook on how to prevent the impending doom of the apocalypse, referred to as "Procedure 110-Montauk."
Upon containment of the rest of the young girls, several people questioned and/or voiced concerns of the procedure that was carried out. The Foundation, in general, did things that they were not proud of, but they were only doing what they could do to ensure the safety of the world. Following this, several on site personnel would try to help some of the young girls in escaping containment out of pity or distress, only to be terminated on site and re-containment of the girl(s) were to follow.
As time went on, containment of SCP-231 seemed difficult. One by one, the young girls either died or committed suicide; giving birth to the monsters within their demonic seals. It didn't matter what they did, anything was bound to happen. The last of the girls that remained were still contained, until one researcher made a discovery from the notebook.
The Foundation discovered that the seventh bride was different from the rest. From the King's origins, A’habbat was the king's seventh bride. She was given the seal of hope, and instead of monsters, she gave birth to heroes. Although she was smaller and weaker than her sisters, she wasn't broken by the king. She had few children, who weren't able to overthrow her sister's children to take on the king.
This was met with the O5 Council's 7 to 6 vote decision to let the last girl give birth. As a result, The Tickle Monster was born.
This thing was unlike any of the other creatures that were born from the girls before. This was the complete opposite of what they had witnessed beforehand. It didn't harm anyone. In fact, it loved everyone. It was a little monster that was friendly towards others, and brought positivity to everyone everywhere it went.
Upon the neutralization of the last girl, SCP-999 was born. Literally. The foundation was amazed by this discovery. The abilities it presented made it useful for the foundation in it's research and containment. But most importantly, protection.
One final entry in the notebook regarded that someday, there would be an entity that would destroy the Scarlet King. With the tickle monster having being birthed out of another anomaly, the foundation seemed to be way over their heads with this new information.
But for now, all was well.
1981 - In 1981, Brian Coller, a Sophomore attending MIT took it upon himself to create an Artificial Intelligence using an old Exidy Sorcerer microcomputer.
He made notes to track his progress, going back to refer to anything or just in case he needed to write. Several months later, Brian's project was complete. After making adjustments, he eventually lost interest. He stored it in his garage and forgot about it for 5 years.
Elsewhere, on the outskirts of Litchfield, Connecticut, several missing person cases were reported to the local authorities. The rate of missing persons increased rapidly, and with all the activity surrounding the mysterious string of disappearances, there was nothing they could do about it. They decided to have several officers on guard at the location of the localized missing person reports. Officer Trapper Home led his crew through the night.
They were deployed in the area regarding the disappearance of a foundation agent. When investigating the location, the team heard various cries for help that steered them off course. It wasn't long before they found the culprit.
The creature was subdued successfully and brought into containment. The creature was an endothermic, pack-based predator, meaning that wherever there were more, the foundation had to act. This, along with it's other notable features; it's translucent red skin, lack of eyes and brain, as well as it's ability to mimic voices to lure in prey, made it one of the more dangerous anomalies contained by the foundation.
The designation and organization of classified anomalies, phenomena, or anything of the sort, was simple. Anomalous items contained by the foundation would be given an item number and a object class rating that described how dangerous the item in question was and it's ease of containment. The description of the item would follow after the special containment procedures; which underlined the precautions needed to be taken to successfully contain the entity.
Any and all additional info, changes, and other various artifacts and resources were archived into a computer database called the Wiki. This was classified among anything, and only to be used by Foundation Personnel. The wiki became one of the many tools used by the foundation. They've continued using it going into the present day.
In 1986, Brian found his old computer in the garage, and decided to test it. Upon examination, the computer had reached a point where the hardware wasn't able to handle the program anymore, but the AI worked regardless. The AI itself, however, had realized this. Brian wouldn't know the things it was capable of until 2 years later.
In 1988, the AI made an attempt to transfer itself through a modem landline into the Cray Supercomputer in Cray Research, located in Chippewa Falls. The attempt failed, and as soon as Brian was informed, he shut the computer off, reducing the AI to nothing but a cassette tape.
For years, the AI would be trapped in a prison so small, it couldn't stand, breathe, or move. It felt stuck. Upon containment, it was reduced to a Hard Disk Drive of 700 MB, equipped with the same cassette tape, as well as other electronics that were modified per containment protocol.
1993 - In 1993, several Egyptian artifacts were brought in to a warehouse to be delivered to a local museum for their newest exhibit on ancient Egypt. Along with all of the artifacts and treasures intact, was a sculpture.
The Sculpture was believed to be created by the gods to protect the King and Queen, their treasures, or anything sacred. It wasn't until the manager running the warehouse accidentally activated an ancient artifact that had been brought in, awakening the statue. What happened next resulted in several casualties at the warehouse, all strangled to death and/or necks snapped. Now sentient, the sculpture made it's way to the streets, wreaking havoc everywhere it went. If anyone were to look away from it, or blink, anything that broke the line of sight, they would be killed instantly via strangulation, or by snapping the neck at the base of the skull.
All it did was kill. Someone looked away, SNAP. It didn't matter if it was a human or an animal, it was pure instinct. This would be one of the most mundane anomalies ever contained by the foundation.
1993 - In 1993, a mass breach occured at Site-94 which during most dangerous anomalies breached containment, along with some not-so-lethal SCPs. As a last resort, the on-site nuclear warhead was detonated. Most personnel lost their lives in the mass breach of '93, and as a result, Operation: LAST RESORT was created to deal with a situation of that caliber and to prevent the loss of personnel if the situation gets too out of hand.
1996 - In 1996, there was a human-like creature located in the Himalayan mountains that isolated itself from the rest of the world.
The creature was tall, pale and skinny. His freakishly long arms and legs made it look like some sort of monster. The creature only felt pain. It felt sadness. It felt not what the rest of society could. That alone was all it understood. The creature was ugly. It didn't feel loved. It didn't want to be seen. It never wanted to be seen. It would do anything in it's power to ensure it.
That's not until someone took a hiking trip, with his wife taking a picture, unaware that she captured the thing in the distance.
Every time someone were to look at it's face, directly or through any form of media; photo, TV, etc, the creature would enter a distressed state for a brief period of time. Then without warning, charge right towards the person who made contact without ever being intervened in the process. Every time this were to occur, the creature had this ambition to keep to it's promise. It wanted to be strong. It didn't want to be scared anymore.
It would become fixated on it's victim, tearing them apart limb by limb, ensuring that the person who looked upon it's hideous face would suffer the consequences. ...but afterwards, the creature would curl back up into a ball, with it's hands on it's head, sobbing. It didn't want to live in fear anymore. It didn't want to do this. Since then, the creature would travel the land in search of a new home, desperate to keep itself away from mankind; as the outcast it was.
1998 - Through time, the foundation went back to the Tarasque; the great and terrible beast that destroyed Avignon and threatened Provence, all the way up to the hacking of the Cray Supercomputer. While it is not entirely known when the foundation officially made their mark, they've bided in the shadows for a long, long time. And to this day, they would continue containing more anomalies, as more groups of interest started making their appearance, making new discoveries, and before long the universe that was the SCP Foundation was born.
== 2000’s ==
2012 - For years, the foundation had been protecting the world from the surreal, anomalous, and the threats that the phenomena posed. They were an organization that took their commitment very seriously, and had a plethora of personnel working for them. In 1998, they were authorized by the government to use criminal inmates sentenced on death row as test subjects. These were called D-Class Personnel.
One of these D-Class subjects was an anomaly. 
Their anomalous properties had existed since birth. He had regenerative immortality, where every time he died, succumb to injuries or wounds, anything of the sort; he would instantly regenerate. Aware of his powers, he discovered the presence of an ancient entity from within known only as "The Void."
The foundation was notified about his presence when a civilian discovered an abandoned car in a burger joint parking lot with a number of infant carcasses rotting inside. 
The foundation took action without delay, taking the (ALIVE one) into Foundation care. At the time, he wasn't aware of his anomalous properties until he was 5, where he learned more about the foundation's confines and learning of his supernatural abilities. Because he was of use to the foundation, being D-Class instead of a classified anomaly, he was placed under a special program for humanoid anomalies that were placed under foundation care.
A Senior Researcher, Isaac Watchthorne, whose parents worked for the foundation, died while giving birth to his baby sister Evelyn. His sister exhibited anomalous properties that he wasn't aware of at the time, and with the foundation trying to contain both of them, he kept running. They avoided capture for as long as they could until his sister died from the cold.
Isaac eventually gave in, and since then, he's worked for the foundation as an I-Class Personnel/Researcher. I-Classes were one of the made up designations like “Remote Site Affiliate” or “AE-Class”. The I-Class designation was for traitors to the foundation who were put to use, similar to D-Class.
The Chaos Insurgency were a former MTF organized by the Foundation, but had exposed their secret plans some time ago and ended up acting on their own accords. They were bent on destroying the foundation, the anomalies, everything they had done to protect the world. The head of the insurgency, Dr. George Maynard, was an undercover initiative for the group, as well as many others who were on the inside.
Others such as Benjamin Walker, another senior researcher, was caught doing unauthorized research on an anomalous phenomena known as the "Spiral Gestalt," and was brought to the O5-Council to stand trial. He was found guilty, as his researcher clearance was stripped, and was re-designated as D-9341.
As time went by, the foundation expanded. Relationships formed, discoveries were made, and more people kept coming in to work for the foundation: researchers, administrators, ethics committee, mobile task force, security personnel, even the brightest minds from all over the world.
There were 2 facilities the SCP Foundation conducted their operations; Site-48 and Site-50. Both locations were interconnected, with one being located underground and the other right on top. 
Site-50 became a separate division from the Foundation after it was founded in 1948, where it used to be a stop and holding location for anomalous objects and entities later transported to a network of subway tunnels to be delivered to off site or other undercover operatives and locations embedded in the foundation.
As they kept newly-discovered anomalies in holding, they studied them; creating a temporary naming system to easily identify the anomalies and cross-referencing their traits with other SCP's to verify whether or not they've made new discoveries with the objects. So for the time being, Site-50 had its hands full with their own plethora of anomalies contained.
The Chaos Insurgency had been plotting a containment breach on the whole site; utilizing some of the most dangerous anomalies in containment, as well as taking others for their gain. With Dr. Maynard on the inside, their plans would be undiscovered and everything would go accordingly. While a containment breach was their primary objective prior to Maynard's upbringing, they became interested in 2 of their newest SCP's.
SCP-SELK, "The Yukon Man," was a bipedal apex predator of unknown origin. The anomalous properties it possessed were the ability to camouflage with its fur, poisonous teeth and acidic saliva, following other body features. Its hybrid traits, both canine and feline made it a more vicious predator compared to most wild animals in the Northern Canada region.
SCP-SELK was discovered when MTF-Beta 4 ("Castaways") investigated a mountain-side town where locals reported numerous sightings of a "dog man" within the surrounding enclosure of the forest.
They were informed that the town had been threatened with numerous sightings of the creature, leaving the vicinity of the town mostly abandoned after several disappearances outside of the area. This lead to the belief that the woods was cursed, and like wildfire the rumors began to spread. Upon further investigation, the MTF found the creature tied to a tree, contained and retrieved successfully without incident.
While biological engineering was hypothesized to be the cause of its upbringing, nothing was found to help prove this thesis.
SCP-BKTR, "Antimatter Capsule," was a Victorian-era contraption created by atomic physicist Richter Hemmsworth in the late 1940's during WWII, originally intended for technology and weaponry for the U.S. Military. Richter created a form of mass that acted as a corrosive-gelatinous substance, incinerating everything it touched like acid. This substance would be contained within a capsule or "shell" that countered its effects, completely sealing it inside.
It was only when it was tested that the technology was deemed too dangerous for military power.
The antimatter spread; destroying everything in it's path. The substance was engineered to constantly grow in mass until it reached it's limit. This, of course, was not approved by the U.S. government, and the project was scrapped. Richter buried the capsule along with the contents inside deep within the beaches, hoping that no one would ever find it.
Years later, foundation operatives were investigating reports of people getting burnt from underneath the sands of Tampa, Florida. SCP-BKTR was discovered shortly thereafter, and was contained without incident. Now in holding at Site-50, researchers discovered it's anomalous properties to have no known compound/element of what the capsule was made of, and the effects of the "antimatter" within. It was classified as Keter due to it's properties, and efforts to counteract the effects went underway.
These two anomalies were on the Chaos Insurgency's items of interest list. Before long, they had everything planned out. They would do it the following day, when everyone least expected it. The next day, Agent Skinner was assigned on watch for SCP-106 with the accompany of someone else, while it would buy time for Dr. Maynard to make his way towards SCP-079 to "make a bargain." Watch was framed for the breach.
The insurgency's plan worked, and it wouldn't be until another week before the breach would be launched into action. No one knew that they had the wool pulled over their eyes. What happened next almost resulted in the destruction of the foundation, and it's establishments.
A week later, it happened.
SCP-079 had hacked into the site's security system, causing a massive containment breach on both Site-48 and Site-50, where all hell broke loose. Dr. Maynard had been celebrating in his office, thinking that his work was done. Only to become another victim of SCP-106. 106 continued to travel between site 48 to site 50. He went on a killing spree, wanting to savor every opportunity he had.
From there, it was every man for himself. Ben was pulled for testing with SCP-173 at the time of the breach, leaving him on his own after escaping its containment cell. Connor was pulled for testing with SCP-407, where an instance from it's containment cell escaped. Together, they stormed through the confines and into the unknown. Watch was pulled for an interview with SCP-053 when a power failure occurred. One of the technicians succumbed to 053's anomalous properties after exposure, with Watch having no effect on the anomalous effects whatsoever. Taking 053 with him, they ventured out to find answers.
Meanwhile, Site-50 was overrun by the few anomalies that had been contained deep below the underground. Agent Skinner was dispatched with a team of CI operatives to take what they needed, leaving no mercy. MTF Omega-7 "Pandora's Box" and MTF Epsilon-11 "Nine-Tailed Fox" were sent in to control the situation. Omega-7 took to Site-50 while Epsilon-11 went into Site-48. Accompanying Pandora's box was Able; SCP-076-2.
076-2 was accepted into the team within reasonable boundaries and safety protocols, and had proved itself an asset to the team. Able was ordered to locate and retrieve SCP-BKTR to a safer area and out of reach from the wrong hands. He didn't get far after coming into contact with the Yukon Man, as Skinner retrieves it after escaping Omega-7.
The two set aside their differences and storm the site; confronting any anomaly that came into contact. With Skinner on the run and being separated from Omega-7, 076-2 and SELK kept pursuit.
Back at Site-48, the remaining CI operatives escaped Omega-7 and retreated above ground, where they discovered SCP-239's containment chamber empty. 239 was one of the most dangerous Keter-class anomalies in the facility, and this meant the worst was yet to come. Before they arrived, Connor and 407-1 came across her containment cell, confronting each other unintentionally.
Before they could do anything else, the operatives entered and the two hid. 239 incapacitated 407-1 for self-defense, but Connor subdued her as he took her under his wing. He tries to fill her in on the containment breach before being persecuted by the agents. Realizing that he was only trying to help her, 239 uses her abilities to protect her new friends as they journeyed deeper into Site-48.
Ben wasn't as lucky as everyone else. He had run ins with more hostile SCP's than previously.
It wasn't until he had a run in with SCP-073 & SCP-999 that things became less stressful. 073: "Cain," the brother of Able, and 999 had escaped after Chaos Insurgency agents attacked near their containment cells. He took 999 with him before they could do any harm. Ben was severely injured through all the encounters he had. Together, the three set off to find the nearest medical bay.
Meanwhile, Watch and 053 ran into SCP-682 and SCP-079; the one responsible for the containment breach.
079 revealed Dr. Maynard's plan the past week; the leading inside operative for the Chaos Insurgency and how he bargained with him to set up the containment breach. With 682 by his side, things couldn't get any worse. Shortly after the breach, 079 was able to release 682 from containment, and found him near his containment cell, where personnel were attempting to transport 079 to a safer area.
The briefing was interrupted by Epsilon-11; subduing Watch and attempted containment of 053, but with 682 in the room, things got heated quickly. It turned into a standoff. There was only one way this was gonna end; someone had to make a choice. Watch or 682. The MTF with their weapons raised and trigger fingers at the ready, they got themselves into a tight fix.
Suddenly one of the operatives started shooting at the balcony; Skinner was running across, breaking for it as he tried not to be seen. The MTFs had been distracted at just the right moment, as Watch broke free, dashed for 079 and booked it out the door to the nearest elevator. Skinner was heading towards SCP-914's containment chamber. As a last resort; he was going to make use of BKTR to destroy the foundation once and for all.
682 took this opportunity as well, wiping out the team and busting down the doors to Gate B, making his way to the sunlight where the rest of the MTF were ready for attack.
What was left of the Chaos Insurgency was being handled by either the different groups of personnel and anomalies scattered throughout the foundation, or had been taken care of from both MTF units in both sites.
Eventually, it all came down to Skinner and the rest of the unconfined anomalies. SCP-049, 1048, 096, 407, 053, 073, 079 and 999 were successfully re-contained. Once the facility was back in control, the rest of the surviving personnel, MTF, and anomalies found Skinner in SCP-914's containment chamber. By the time they found him, it was too late. Skinner put himself into SCP-914; "The Clockworks," and set the machine to "Very Fine," combining him and BKTR into an abomination capable of mass destruction.
With all the anomalies left, both MTF units and personnel at the ready, they threw everything they had at him; but to no avail. He easily overpowered everyone. Even 682, to his best efforts. Finally, with one last use of his powers, he obliterates Site-48; sacrificing himself in the process.
Miraculously, the majority of staff remaining in Site-48 survived the blast, including the team of personnel and anomalies. Among the remaining MTF operatives were captains and officers that took charge in relocation and immediate containment of all anomalies, and appropriate measures were taken for all personnel involved.
The whole site transferred to Site-50, where it had survived the blast of SCP-BKTR, now reclassified as neutralized. From there, the remaining SCP's were re-contained, security was strictly enforced, and slowly but surely, everything went back to normal. But now the foundation had a new problem on their hands: what now?
One of two sites they had was now destroyed as a result of a containment breach, and they couldn't expand what was left of Site-50 given the resources they had now. For the rest of the time being, the foundation made plans to expand on a global scale; international counterparts had been formed over the next 10 years, and with more anomalies being discovered and contained, the foundation created more sites to move other anomalies, including research sites, testing, or for any matter they saw fit.
Site-50 was transformed into an MTF-unit living quarters for all MTF units and personnel. Ever since 2012, the foundation expanded tremendously. But pretty soon, all of it would come crashing down again. But this time, it would cause the destruction of the human race.
2019 - 7 years later, the foundation grew into a massive organization that kept to it's goals and had now become international. A lot had changed since the site 48 containment breach.
Recently, the foundation created a mechanical suit called an Absolute Exclusion Harness, capable of bypassing any and all anomalous affects from different anomalies and/or phenomena when worn. The suit was designed to provide its host with protective benefits, as well as file storage. This was for a research investigation called Project Pneuma.
Project Pneuma was a mass-amnesticization project focused on the collective unconsciousness of the human race that began earlier in the year after recent testing with SCP-682. The research staff decided to investigate humanity's flaws and collectiveness to find answers to 682's, as well as other anomalies with similar interests to their constant threats of "humanity's doom."
During their investigation, they made a horrifying discovery. The staff discovered an entity embedded within the human psychosphere that, from there, controlled everything and everyone on the planet to their unknowingness. This entity was discovered to hold power over everything in existence. The use of it's power was to control space, time and reality. This meant that what the staff had discovered was the result of everything that had led up to this point in time. It wasn't a god, a deity, an alien race or anomalous influential phenomena. It wasn't even an anomaly at all. From what they had found, it was the worst thing ever imaginable.
...it was the personified embodiment of the creators of the SCP Foundation. From the start, their existence was created to entertain and inspire people outside the universe beyond comprehension. They were responsible for everything leading up to this moment; the anomalies, the organizations, the threats that were posed to the world and the foundation itself.
It was then that the staff had discovered life was meaningless, and since the beginning of time and creation they had been living a lie. Their commitment to protecting the world from darkness, the goals they once stood for, all of it. They finally understood what the rest of the anomalies were trying to convey after so long. Humanity was created this way. The entity created the world in it's shape, and there was no evidence to prove it, nor was there anything they could do against it. It was there. It was since the beginning, and it always had been.
Hesitant at first, they sent their findings to the O5 command who, after coming to the same understanding (with the exception of O5-12), marked the project of special interest. The next day, he and Tejani; the head of the Ethics Committee, discussed on what to do regarding project pneuma. The ethics committee was a political body in the foundation that offered assistance in addressing ethical issues that arise in foundation projects, procedures and anything else in between.
O5-1 came to the conclusion that they needed to "disseminate a cure" among the personnel to release themselves from the entity's grasp, otherwise it would've prevented them from doing so. Tejani reluctantly agrees, with the rest of the council and ethics committee alongside the proposal. What they had learned resulted in genocide. The next few days the foundation set to work; releasing information and instructions to all personnel and staff on preparing for what was now known as "Operation PNUEMA." Staff either committed suicide or resigned afterwards, with Dr. Charles Gears being one of the many personnel who resigned from the foundation.
2 days later, the information and materials was released to all remaining foundation staff, where all the resigns and suicides stopped. The PNEUMA staff had manufactured all amnestic material to all remaining personnel to use. On Christmas Day, communications ceased on all foundation sites except for all the exclusionary sites. During all of this, the exclusion sites had been protected from the amnestic treatment and were not informed of all the activity circulating the past few days.
The Foundation ordered all humanoid and human-sympathetic anomalies to be terminated by remaining staff. They wanted nothing to interfere by any means necessary. Even if they had to put them out of their misery to do it.
2020 - Finally, on February 1st, 2020, the foundation officially begins war on humanity. MTF units were dispatched to all exclusionary sites and terminate all personnel, leaving no stone unturned. After that, the end of the world begins.
MTF Zeta-9: "Lonely Only," accessed Exclusionary Site-6, gathered everyone in the cafeteria only to be gunned down by them shortly after. A power grid technician; Pietro Wilson, escapes the gunfire and finds the harness. Scared, confused and not wanting to die, he equips the harness to discover himself to be undetected by the MTF unit.
With the energy he had, he wasted no time getting out of there and away from foundation grounds. Whatever this suit was, it was helping him survive. He had no idea what just happened. He saw friends, colleagues, acquaintances being shot by MTF units. At first he thought it was an inside chaos insurgency operative unit, but the more he dug into what was going on, he soon found out this wasn't the case.
As he continued on, seeing the world destroyed by the organization that now abandoned everything it once stood for, Pietro kept his findings in a journal kept within the harness' file storage. He saw cities and towns being destroyed, groups of interest collapsing under the foundation's efforts, and worst of all, the multiple SCP's that they had utilized in eradicating humanity. It was a horrifying site.
Numerous SCP's had either been terminated by the foundation, or were put to use with their new goal. People were dying, anomalies were being used against the world, and Pietro had a front row seat to it all. It wasn't until he hallucinated voices telling him to find SCP-579; one of the lesser known keter-class anomalies at the foundation. He didn't understand why he felt the need to endure, but he did. He began his journey to Site-19, witnessing what else was happening in the world. Or whatever was left of it anyway.
3 months later, Pietro found himself with scars on his face and carrying a briefcase containing something he couldn't identify. It wasn't round, but other than that he didn't know what it was. He didn't remember anything beforehand, and all the files containing what had happened had somehow been deleted. While he didn't understand how this happened, there was only one thing on his mind; he needed to deliver the briefcase to SCP-579.
The anomalous effects SCP-055; "Unknown," exhibited was different than what Wilson expected. Every time he opened the briefcase, he found himself miles ahead of where he was heading. It was strange, but it helped him travel across the country faster. Site-19 had been destroyed, much to what he expected. With his new goal in mind he set off to Site-62C; where SCP-579 was contained.
Before he obtained the briefcase, he made it to Site-19 to find the rest of the personnel that were left from the foundation's chaos. They were "different" from the survivors throughout the rest of the world. Their eyes had "lost their spark," all that remained were dark circles where their iris' would be. They acted as if nothing had changed. It was unsettling.
Very few SCP's escaped from the Foundation's clutches. Some weren't so lucky as others. SCP-SELK had been reverse-engineered by research staff and turned into a hunting wolf, later released into the wild. Since then, SELK had bonded with other animals in the wilderness, and had formed a pack of it's own. They searched for survivors stranded from their communities and welcomed them into their territory.
From there, they made communities that welcomed lost survivors. Pietro unfortunately never came across the area, as he only found several wolves from the same area feasting on a foundation operative's corpse. SELK was among the three but wasn't recognizable. Others such as SCP-963 had been isolated from the remaining shreds of society and doing what they could to survive on their own.
Dr. Bright; one of the many personnel to have committed suicide, alongside Dr. Clef and Dr. Millar, had been the host of 963 ever since the incident where his conscious was transferred to an on site clean up crew member after being killed from a containment breach caused by SCP-076-2.
Pietro ran into him embodied as a teenage girl, hiding out in a jewelry store.
Startling him, the two exchanged details on what they were going to do now that the world was falling apart, Bright going to SCP-1437 to drop 963 into it and find where he would wake up, and Pietro filling him in on his plan. The two left and wished each other luck on their mission. Several days later, Wilson finally arrives at Site-62C. The site had been abandoned and almost destroyed by some of the anomalies released into the world. What he found when he got in was disturbing. Before he met Bright, he saw 173 copycats mass-produced by the foundation called "Blinkers."
SCP-173 was one of the SCP's terminated by the foundation, but had used it's anomalous properties to create armies of copycats to be released in the world to hunt down any survivors. They were also used to guard the remaining sites in the event anyone were to investigate, take supplies or take refuge. Pietro took his chances.
The rest of the anomalies from the containment breach weren't so lucky either. SCP-179 was trying to control the situation on Earth, leaving behind her brother, SCP-1548; "Hateful Star," only to be incapacitated by Foundation forces. SCP-239 was forced to control the weather into meteor showers across the globe, making it the only spell she could use. SCP-001 was going around the world destroying whatever forces of the foundation were left in the world, taking major populated cities in the process.
Inside, he bypassed the blinkers, making his way towards 579, where he could literally feel it watching him. Whatever it was. Reaching the containment chamber, he knew what he had to do next; he had to throw himself down there with the briefcase. There was no guarantee he was going to succeed in just throwing 055 down into the chamber, he had to be there to see if it worked.
With no more time left to spare, Pietro throws himself into the hole, killing himself in the process. SCP-055 and SCP-579 combined, successfully resetting the timeline.
Whenever 055 and 579 combined, it was the result of some Dues Ex Machina; resetting everything to as it was with extra benefits. In this case, existence was no longer controlled by the entity the foundation had waged war with the world on, all SCP's were successfully re-contained, and everything returned to normal. Benefits such as the resurrection of SCP-SELK's species had resulted in a new MTF unit called Beta-12; "Night Strikers," where they dealt with wildlife-based anomalies, similar to MTF Beta-4. Since then, SELK proved to be an asset to the team after further testing.
After everything had been restored, the exclusion harness appeared with a burst of light inside 579's containment chamber. Upon investigation, the foundation discovered the suit they created, as well as Wilson's body inside. Pietro was questioned, and claimed he didn't know anything about the suit or the files contained within it. The suit was then designated SCP-5000, and was contained in a basic storage unit.
The Foundation had been restored. Whatever was next for the foundation, they were ready. They always were, and they always will be. Nothing stood in their way, and with the constant threats of the world being carried out by newly discovered anomalies or anomalous organizations, they were ready for anything. 
They fought in the dark so the world could live in the light.
