Sensors, AI, directed energy tech, nanotech, electronic warfare, surveillance, ocean and space. Yes, that about covers all the spoopy bases.

The Naval Research Laboratory has implemented a tech called TORPEDO, presumably to aid in searching of the Ruth H. Hooker digital library. Who was Ruth H. Hooker? Real person or no? Is the book of lock and key contained in there under restricted access?

Which of the magick/tech in the NRL opens access to the book? Could it be the nanotech? Is that why you say it lies within? Because we all have nanotech inside our bodies to some degree?
