The air at Gate Zero smelled of three decades of frozen paperwork and ozone.
Across the narrow stone bridge that spanned the Sub-Harbor Brine Shaft, the temperature hovered at minus two point one four degrees Fahrenheit. It was the exact freezing point of salt-saturated municipal quicklime. Sixty feet below the rusted iron floorplates, the black sump water churned in a sluggish, foaming vortex, releasing dense white vapor that frosted the marble handrails in delicate, razor-sharp needles.

The charge nurse had both hands clamped onto the chrome push-handles of Clara’s transport gurney. Beside her, Lin Mei pushed up her cracked tortoiseshell glasses with a gloved thumb, her sneakers finding purchase on the frost-dusted tiles as they cleared the final threshold of the approach ramp.
“We’re across the perimeter!” Lin Mei called out, her voice tight with strain. “The inductive ground wire on Gate Zero is holding! The electromagnetic locks on the secondary barrier are dead!”
Elena glanced down at the portable cardioscope strapped to the gurney frame. The small green screen flickered in the cold draft, tracing Clara’s slow, hypothermic heartbeat.
