PISCES

The Paranormal Intelligence Section for Counterintelligence, Espionage, and Sabotage (PISCES), also known as the Section, is Delta Green's counterpart in the United Kingdom. Created on June 26, 1940 by an executive order of Winston Churchill, PISCES continues to serve as the official arm of the British government charged with defending Great Britain from supernatural threats. Unlike Delta Green, PISCES has studied the secrets of the unknown for possible exploitation in the UK's national interests.
