The horrors of the Great War awoke movements in both England
and Russia to destroy, cover-up, capture, and study those
things discovered that were beyond human understanding.
In Britain, in 1916, with the British Intelligence apparatus
MI-6 pushed to the limit, the government looked in unusual
places to curb the U-Boat threat which had a stranglehold
on international shipping. They found Lt. Commander Frederick
Ramsey and his stable of “Talents,” intelligence analysts that
claimed to possess psychic abilities allowing them to see remote
locales, and even the future. By World War II, this force
was designated MI-13, called PISCES: Paranormal Intelligence
Section for Counter-intelligence, Espionage and Sabotage.

30 DEC 1942: William J. Donovan, commander of the OSS, and David
Cornwall, commander of PISCES, meet at Kilmaur Manor to work out an
intelligence-sharing process between PISCES and OSS/Delta Green. Donovan
is introduced to the capabilities of PISCES’ unnatural Talents
for the first time.

1 MAR 1943: William J. Donovan learns that PISCES had sent agents to
assassinate the OSS/Delta Green team in Australia and seize pre-human
books and artifacts that supposedly could allow humans to know or
control the future. Ties between Delta Green and PISCES are severed.

13 DEC 1945: The Paragon Foundation is established in Toronto, Canada,
as a front by PISCES to evaluate psychic phenomena and gifted individuals
in the Western Hemisphere. PISCES also uses the foundation to
carry out secret investigations of unnatural activity in the region.

27 SEP 1947: PISCES agents observe the reactivation
of Delta Green, but do not resume
the close relationship they shared
during the war, due to concerns over possible
security leaks.

19 FEB 1968: Having been led to investigate a series of “anomalous”
sites surrounding the Severn River in southwestern Wales, PISCES
Brigadier Charles Balfour orders a large-scale raid on the town of
Goatswood. PISCES, backed by elements of the British Army’s Gurkha
Brigade, massacres the inhabitants, demolishes the town, and confiscates
a cult-related object known as the Moon Lens. During the Goatswood
raid, several PISCES agents are infested by the insects from
Shaggai, who infiltrate deep into PISCES.

In 1999, agents of Delta Green discovered that an
alien intelligence, capable of mentally controlling
humans, had infiltrated the United Kingdom’s government
through the organization PISCES. Delta Green
immediately broke contact in order to gather intelligence,
but it made little progress before the Program
launched. The Outlaws let it go. The Program maintained
limited contact.
