Subterranean Scan

Overwatch complete, but the lowest sectors demanded recon. I navigated down the wicker trellis to the balcony floorboards, tracking a faint vibration near the corner drainage grate. Beneath the slotted cast-iron disc lay a shallow reservoir of still runoff. Floating amidst the murky depth was an intact brass hex nut, submerged just beyond arm's reach. Using the straightened paperclip from my belt, I angled the hooked tip through the iron aperture, snagging the inner thread. With deliberate torque, I hauled the heavy hardware to the surface. Dense ballast acquired. Every layer of the perimeter yields assets.
