The Perimeter Restricted Zone

The Headland — northern forest where old-growth redwoods stand and drone shadows move through the canopy gaps.

The Long Water — interior valley where fog chokes the lowland reservoir, silent with the kind of silence that has weight.

A town that erased itself from every map before the Cascade and has only gotten better at it since. The roads leading in are gone — not overgrown, removed, the asphalt physically torn up and the ground replanted. Drone coverage over this grid square shows anomalous gaps that could be terrain interference or could be something else. Signals intelligence detects nothing. Thermal imaging detects nothing. Satellite passes show forest canopy and coastline and no evidence of human habitation, which is itself evidence because the vegetation patterns are too uniform to be natural. Whoever lives here — if anyone lives here — has achieved what every settlement in the Sprawl dreams of: genuine invisibility. The drones patrol the perimeter but do not enter. Whether this is a technical limitation or an agreement is unknown.

The highest non-orbital point in the Sprawl — 785 meters of coastal mountain bristling with military-grade infrastructure that predates the Cascade and has been upgraded by hands unknown. Radar arrays rotate in slow sweeps. Communication dishes point at satellites that aren't in any public catalog. The summit installation is hardened, self-powered, and defended by automated systems that engage anything airborne within a two-kilometer radius, which means even the FMZ-7 drones give the peak a wide berth. Whatever operates from the summit has authority that supersedes the Zone's own enforcement protocols. The trails up are mined. The roads are cratered. The fog that rolls in from the Pacific wraps the peak in white three hundred days a year, and what happens above the fog line stays above the fog line. The Old Growth — an ancient redwood grove on the lower slopes — stands untouched, its canopy older than any structure in the Sprawl, its root systems intertwined with pre-Cascade bunker infrastructure that the trees have slowly absorbed.

The bay narrows here to its most fortified chokepoint — the Golden Gate Dam spans the gap, and the Cyber Castle compound occupies the ridgeline above with a sight line that covers every approach by land or water. The Lookout sits on the island in the bay, a former immigration station turned surveillance platform whose sensors paint the water surface with enough resolution to track individual swimmers. This is where the Restricted Zone meets the Sprawl's most valuable infrastructure, and the concentration of defensive systems is dense enough to create overlapping kill zones that leave no dead space. The shallows themselves are mined — acoustic sensors in the seabed, pressure plates on the bay floor, and autonomous underwater vehicles that investigate anything larger than a harbor seal.

Coastal cliffs dropping hundreds of meters to cold Pacific water, the concrete remains of pre-Cascade military batteries embedded in the headlands like teeth in a jaw. The gun emplacements that once pointed seaward now house sensor arrays that point in every direction. Bunker complexes tunnel into the cliff face, their entrances sealed with blast doors that show no corrosion, suggesting maintenance by someone or something. The wind here is constant, salt-laden, and strong enough to ground small drones, which creates the Zone's only reliable surveillance gap — a narrow window during winter storms when the coastal sub-sectors go briefly unwatched. People have tried to exploit this window. The wreckage at the cliff bases suggests the window is narrower than they calculated.

Eastern slope above the bay, dense vegetation reclaiming pre-Cascade roads that the drones patrol but nobody maintains.
