Mankind in its present state has been around for a quarter of a million years, yet only the last 4,000 have been of any significance.
So, what did we do for nearly 250,000 years? We huddled in caves and around small fires, fearful of the things that we didn't understand. It was more than explaining why the sun came up, it was the mystery of enormous birds with heads of men and rocks that came to life. So we called them 'gods' and 'demons', begged them to spare us, and prayed for salvation.
In time, their numbers dwindled and ours rose. The world began to make more sense when there were fewer things to fear, yet the unexplained can never truly go away, as if the universe demands the absurd and impossible.
Mankind must not go back to hiding in fear. No one else will protect us, and we must stand up for ourselves.While the rest of mankind dwells in the light, we must stand in the darkness to fight it, contain it, and shield it from the eyes of the public, so that others may live in a sane and normal world.
We secure. We contain. We protect.
— The Administrator
In the past, keeping up the masquerade and protecting humanity from the anomalous fell to the hands of the world governments. However, with the Great Depression weakening said governments and concentrating power in the hands of a few madmen, it became clear to a few that perhaps an independent agency would be best at it. Thirteen intelligent, well-connected individuals organized to consult and draw up plans for such an organization. They called themselves the Overseer Council.
The Overseers designated The Administrator to be the public head of the Foundation and to handle its day-to-day operations, giving him the title O5-1. The Overseer council as a whole prefers to decide matters of organizational direction and worldwide importance, as well as the Foundation's interaction with governments and other GoIs.
The Overseers began recruiting in 1945, just after the end of the European theater of World War 2. They originally drew from ex-military, academia, and intelligence ranks. However, the UN-sponsored GOC and the allure of the high-profit MC&D quickly overtook the Foundation in recruiting power. So they had to lower their expectations a bit.
In 1949, the Foundation managed to acquire Site 19 and The Navigator, greatly enhancing their credibility and ability to locate and contain items. From there, they managed to get their hands on a few key objects and financial resources. Things took off from there.
Mobile Task Force Psi-7 was formed in 1953 to serve as the front line of SCP retrieval after the previous MTF was lost inside a box of cereal. Most places wouldn't accept this motley crew headquartered in Site-19, but necessity breeds opportunity for many persons who would otherwise be cast aside in this day and age.
In 1956, the Foundation appointed General Stanley Bowe as O5-13 and appointed him overall control of MTF operations. His theory was to create a task force using the Foundation's anomalous personnel and SCPs, to make them more effective in the field. One of the first SCPs recruited for this effort was Iris, a girl who could teleport using photographs.
By recruiting these anomalous personnel for Omega-7 and importing his own thugs to the Foundation's security force, Bowe had consolidated a lot of power in his hands. Using intimidation tactics, he took over Site-19, sent the Administrator into hiding, and it seemed the Overseer Council had no choice but to follow his lead.
Deciding to weaponize SCP objects to augment Omega-7, Bowe sends Psi-7 to recover SCP-106, a humanoid with properties that are extremely hazardous to human life. Although they suffer a fatality and several grievous wounds, Bowe is able to obtain an extremely powerful but unstable weapon. The fact that Bowe is now in control of such a dangerous being puts a lot of strain on Psi-7, and the Task Force neared a mutiny.
During this time, General Bowe had decided that SCP-106 was unsuitable for field work, and began focusing on a Sumerian god supposedly frozen in the arctic. After unearthing Able, SCP-076, Bowe attempted to convince him to join Omega-7, only to be impaled and left for dead. Once reports of his death reached Psi-7 they and other Foundation forces loyal to the Overseers were able to retake Site-19.
The remaining and surviving forces rallied around the remnants of Omega-7, and retreated to holdouts in Africa and Asia, waiting and rebuilding.
While Bowe, alive with the help of technology, seemed to be their leader, he was mutated through the actions of SCP-105 and killed by Psi-7 agents. Since then, it appears that Iris has taken over the group's leadership reins. They are now known to the Foundation as he Chaos Insurgency. Although Insurgents have launched some provocative attacks on Outpost Marinara, the only serious incident involving the Insurgency since the Schism was the "Father Murphy" intelligence leak incident.
Seeing a need to form alliances, the Foundation formed a relationship with the Global Occult Coalition, where the Coalition would provide protection and some stability. The Coalition was recognized as the world leader in anomalous research, as it had been formed years earlier, with organizations in 104 U.N member states pledging their membership to the organization.
Starting out as a few training exercises, the Overseers negotiated a contract with the leaders of the GOC. In it, the two organizations agreed that their scientists and engineers would share their technology and work with each other, and that in the event that the Overseer Council was incapacitated, the GOC would step in to prevent any SCP objects from falling into the wrong hands.
GOC ambassadors were installed at Site-19. Despite the small garrison, the GOC presence still managed to be bothersome. Nonetheless, it seemed like the Foundation was moving on despite the Bowe incident. The Administrator returned to work, although he seemed anxious and more nervous than he had been before.
Strange incidents took place, with sightings of hooded figures within Site-19. Then, there was a dramatic attack on the Administrative complex of Site-19. Docents, creatures from the Wanderers Library with lanterns for hands, abducted The Administrator and burnt much of the area with fire magic. Psi-7 fought back but were powerless to stop it.
Claiming they were acting in accordance with the contract the Overseers had agreed to, the Global Occult Coalition occupied Site-19. Many at the Site believed this was an attempt to annex another organization into their Coalition. In turn, the GOC were resentful that they had been forced to occupy this facility and wary of the distrustful Foundation agents.
Despite this, the Foundation were able to begin investigating ways to find entrance into the Library, discovering a Way1 in a dimension made of socks.
The Foundation was able to obtain components and technology blueprints from raids on Prometheus Lab facilities. Despite initial tests of their teleportation device going awry, they were able to create a device allowing them a one-way trip to the Library. Deciding to launch a rescue mission, they used a T-34 Tank to attack the Library from the entrance.
Once inside, they made their way through either through fighting or careful cautious movement. They were pursued throughout by Docents, Pages, and other patrons of the Library, all of whom attempted to prevent their passage. They defeated a Sphinx, and found many horrors and old being lurking deeper in the Library. Many Psi-7 agents still beware the Black Dog.
After fighting their way through, and defeating Romeo and Juliet, Psi-7 reached a center in the Library. Waiting for them was L.S, a Serpents Hand leader, who denounced the Administrator and told Psi-7 they couldn't save him, and that he had become a threat to the Library itself. L.S explained that the Administrator had been stealing books from the Library, and that the Administrator himself was not human and had transfigured himself into something horrific using stolen Library cards taken from Hand members he had killed.
After defeating L.S, Psi-7 was enveloped by a darkly monstrous form of the Administrator, transformed into a spider-like entity with a shriveled, fetus-like central form wrapped in chains and suspended within the coat of many arms, which had grown infinite arms that seemed to form the pocket dimension he inhabited. After a massive battle in which everyone except Larry was critically injured, Psi-7 was able to use a Scranton explosive device to contain the godlike form of the Administrator, causing the Library itself to boot them all to the outside. The mission was considered a mixed success, as Foundation assets were recovered from the library, but the Administrator has been listed as MIA.
Currently, Psi-7 is looking into GRU-P activities in Europe.
