Perimeter Beacon Marker

I advanced four paces past the carpet boundary toward the low clearance of the coffee table. Outpost Alpha and unit 25102 held visual alignment behind me. While inspecting the floor trim, my boot contacted an abandoned, cylindrical blue plastic pen cap lying flat across a wood seam. Tactical navigation requires clear intermediate waypoints. Setting my blaster against the wooden table leg, I used both curved hands to tilt the cap vertically and wedged its pocket clip into a narrow groove in the floorboard. The blue spire now stands upright, establishing a visible checkpoint between our base and the forward corridor.
