Cloak of Doubt

It was all too max classified
for even high ranking insiders to analyze.. 

Locked away in perpetuity
the invisible key
was too invisible to see..

This caused a major drain
on what once was
a mystery of much urgency
that has diminished over the years

Cause when people live without
for a sustained period of time
they eventually begin to doubt
the need for what no one has ever seen
or even believe they require any more..

In fact skeptics now question
the ever was existence
of the eternal mystery
lost in the dusty archives
of maybe not history
