Of course coming events cast their shadows before, but this shadow was 400 years long!
The following advertisement appeared in the July 1953 issue of several magazines:

The Perpetual Order of Seekers After Truth
POSAT
an ancient secret society
Most readers passed it by with scarcely a glance. It was, after all, similar to the many that had appeared through the years under the name of that same society. Other readers, as their eyes slid over the familiar format of the ad, speculated idly about the persistent and mildly mysterious organization behind it. A few even resolved to clip the attached coupon and send for the booklet—sometime—when a pen or pencil was nearer at hand.
