The history you know is only a fraction of the truth. A truth so black and frightening it was decided that for reasons of national security it should be forever hidden from the public…until now.

1920, September 1: President Woodrow Wilson forms an elite governmental taskforce codenamed Threshold. Recruits range from law enforcement officers, military personnel, scientists, archeologists, doctors, librarians and regular civilians. All applicants have been thoroughly screened: mentally, physically and spiritually. Agents are given Double Black security clearance and rigorous training in self-defense, firearms, arrest theory and the occult.

Months earlier, President Wilson was injured in a failed assassination attempt by members of the Cult Of The Black Goat, unscrupulous traitors who would see man’s dominance over this planet overthrown by ancient and evil beings. Setting upon the President at his residence and spiriting him away to a clandestine ceremony, cultists bound and assailed him. Their intent was to offer the President as a sacrifice when they opened a gate to another reality. Fortunately for Mr. Wilson, something went wrong, leaving him the sole survivor. These events may never be known, but what is known is this:

As long as there are things lurking just beyond our reality and traitors who would seek to bring them here, we shall be there waiting at the Threshold.

–President Wilson in a secret address.

1920, November 21: Newly trained Threshold Agents are placed into society and given assignments. Protecting an unknowing humanity from forces so dark and ancient and alien that to comprehend would surely mean madness…and to fail, absolute destruction…

What happens next is uncertain…but whatever the outcome, the future lies in your hands.
