The Hoffman-Browning Manuscript
an ancient manuscript with mysterious properties
A 23 page manuscript, each with a different picture. All of them are abstract designs made up of Hebrew words. Believed to have been made during the 14th century in Spain. It was written by a Kabbalist, and if properly translated should allow the characters to contact the VALIS Satellite.
Currently in the hands of the Knights of the Lambda Calculus.
