A Prince took a photo of the hall?

Answer >

Not a Prince, a prinst, which was the commonly used term for Permanently Postioned Recording Instrument (or P.P.R.INST.).
There were also Mobile Airborne Recording Instruments known as martians (you'd call them drones), and a few Mobile Waterborne Recording Instruments known as we'reBoats, or wereBoats. Martians and prinsts were pretty ubiquitous during the years humans dwelled in sanctuaries.
