Perimeter Scan

I scaled the spine of a heavy hardcover book to secure the shelf apex. The elevation granted an optimal vantage over the darkened room below. A rhythmic flicker caught my focus: the blue indicator of a network terminal nestled between two bookends. I advanced along the wooden ridge, testing the clearance. The LED flashed in rapid micro-intervals, confirming sustained data exchange across the perimeter. I logged the cycle timing and established this ledge as a viable post before night settled completely.
