The Greylock Tapes Wiki

SimioDyn USA is a mysterious technological company responsible for many of the events throughout the GREYLOCK Tapes.

History[]

SimioDyn USA was founded in 1883 by the great-great-grandfather of Percival C. Rothwell. Sometime before or around the early 1960's, Percival Rothwell was the company's president and CEO for an unknown period of time.

In 1963, SimioDyn was involved in the assassination of U.S. President John F. Kennedy after he refused their plans for the National Access Initiative program. Some time after Lyndon B. Johnson was sworn into office, SimioDyn launched the NAI program, allowing them to spy on people in their homes and businesses for decades to come.

In 1987, SimioDyn made contact with the Morelli Construction & Mining Company to excavate Mount Greylock to build a facility for Unit 13 with the intention of doing experiments involving thoughtforms. However, the project resulted in unexplained phenomena around the mountain and Berkshire County, which included home invasions, bodies falling from the sky above Cheshire, and fetuses literally disappearing from the wombs of pregnant women.

Despite these occurrences, the Unit 13 facility was set up sometime before or around 1993.

SimioDyn USA was shut down in 1998.
