Black Hours

Cracks appear in the wall of secrecy involving crash/retrievals of non-human intelligences, the data breaches resulting from a schism between opposing factions of gatekeepers in a shadowy maze of unauthorized special access programs. Among the particulars exposed by whistleblowers is the startling revelation that after decades of analyzing off-world materials, our brightest minds remain at a complete loss, not only due to the perplexing wreckage but also as to why such advanced beings were so interested in a desolate expanse of scrubby desert in New Mexico.

A 15th-century illuminated manuscript recently discovered in the deepest recesses of the private archives of the Vatican might hold the answer. When deciphered by an occult fraternity, the curious variant of a devotional book known as "Black Hours" is shown to contain a secret calendar marking the phased intervals of human perception to a hyper-configuration that is believed to have attracted a mysterious presence.

To establish the precise location of this anomalous feature, information disguised amid ancient pictographs on a cave mural must be correctly interpreted - a process that requires someone who is acutely attuned to those that left the cryptic message.
