The **British Occult Service** (**BOS**), also known as **MI666**, is the United Kingdom's primary paranormal agency, originally founded as a subdivision of the Secret Intelligence Service (MI6) in 1907 by King Edward VII. It is a voting member of the Council of 108.

## History

### Founding of Three Portlands

As early as 1899, the predecessors of the British Occult Service were aware of the existence of Three Portlands. In 1905, what would become the BOS made a deal with the genius loci of Three Portlands to house Sidhe refugees from Avalon within the pocket universe. These Sidhe formed the district of Little Avalon within the city, as a refuge from the inevitable Collapse of Avalon.

However, the BOS remained mostly disinterested in the city-realm; though, after World War I, the BOS mostly pulled out of Three Portlands in order to hunt down occult activity on Earth and prevent another Occult War. The city council of Three Portlands remained unrecognized until the genius loci was inducted as "the Mayor" within the city charter in 1922.

### Search for Randall

In 1927, after J. C. Randall's disappearance while exploring the Multiverse through Ways, Sir Robert Durant of the British Occult Service led a search party to find Randall. Durant only managed to trace Randall's steps to JCR-072 until they found a now-collapsed Way that Randall left from. He theorized that Randall either trapped himself in a low-level universe or was killed by the Thule Society.

### American discovery of Three Portlands

The BOS attempted to hide the existence of Three Portlands from the United States; nevertheless, Bureau of Prohibition agents tracked Chicago Spirit operations to the city in 1929.

After a standoff ensued between Director J. Edgar Hoover and the city of Three Portlands that was only ended by President Herbert Hoover and the Hoover Mandate, the BOS was highly displeased and competed with the Bureau of Investigation's UIU. Though never directly fighting the UIU, tensions were still high until 1939.

### Seventh Occult War

In 1939, MI666 formed the Allied Occult Initiative alongside the Holy Order of the Knights Templar, fighting in the Seventh Occult War, an anomalous shadow war taking place during World War II between SS Ahnenerbe Obskurakorps and the AOI. They approached their rivals and newfound allies in the FBI UIU in 1940, signing the Howard-Grant Agreement that guaranteed British non-involvement in Three Portlands from that point forward in exchange for UIU resources. According to Josef Boller of Obskurakorps in a letter to Director Konrad Weiss, MI666 agents were counted among Obskurakorps' diverse group of enemies.

#### Battle of Portlands

In 1943, the BOS worked with the UIU to defend Three Portlands during the Battle of Portlands when Obskuracorps commandos and Thulian battlemages apportated onto the Isle of Portland and created a Way into the city with the goal of capturing ICSUT Portlands and looting the AOI storehouse. With the assistance of ICSUT, the municipal police golems and Portlandser citizenry, Obskurakorps was driven out of the city.

#### DIAMOND PALACE

Starting in 1939, alongside the Occult and Supernatural Activity Taskforce and the FBI Unusual Incidents Unit, MI666 utilized the Crown colony of Other London as a staging ground and training facility, as well as a labor camp. This was primarily utilized for Allied Occult Initiative operations requiring rapid transport from North America to Europe. The AOI's use of Other London ended in 1943, after a vote was held to close the Other London Bridge Way in light of the SS Ahnenerbe Obskurakorps' attack on Three Portlands.

### Formation of the GOC

MI666 presumably became a member of the Council of 108 after the Seventh Occult War, contributing resources to the newly formed United Nations Global Occult Coalition.

### Covert attack by PENTAGRAM

In 2017, the US Department of Defense's PENTAGRAM used SCP-6571 to attack several governmental anomalous intelligence agencies, including the British Occult Service. On 3 February, the BOS contacted the SCP Foundation regarding several of their operatives at their London headquarters committing suicide. The Foundation determined this to be the effects of SCP-6571-1.

## Alternate realities

### U-3931

In November 2024, it was discovered by the United Nations Global Occult Coalition that SCP-3931 would kill all lifeforms in the universe. On 8 November, both the British Supernatural Intelligence Service and the US DOD PENTAGRAM sector offer assistance to stop the ritual. After discovering that 3931 was the result of a GOC error in a ritual to assassinate certain targets, both MI666 and the O5 Council of the SCP Foundation expressed anger, though continued cooperating to stop the K-class Scenario.

On 12 November, after O5-6 appeared in London to quell any XK Scenario fears to overwhelming failure, MI666 reported that they could no longer support the Foundation due to rising anomalous activity in the United Kingdom.

### U-5000

In U-5000, during the SCP Foundation's autogenocidal war against humanity in order to combat the Entity, the British Occult Service directed citizens to take refuge in SCP-1678. After UnLondon reached capacity, the Foundation detonated a nuclear device planted inside the city.
