The "All-Seen" project wasn't just a map; it was a conquest. The drones were designed to penetrate walls using T-wave imaging, turning the private sanctuary of home into a transparent box.
"If they scan this building," Elara said, laying out a series of translucent overlays on Julian's desk, "they'll see the hollow joists. They'll see the way the elevator shaft is used as a heat-sink. They'll see you."
"I can't be seen," Julian said, his voice flat. "If they index me, they index my clients. They index the last fifty people who had the right to be forgotten."
"Then we build the Moiré," Elara said.
The trope of "Mutual Invisible Guardianship" reached its zenith that week. Julian used his knowledge of signal interference to create "noise," while Elara used her knowledge of the building's hidden geometry to place that noise where it would be most effective.
They spent their nights in the guts of The Obsidian. They moved through the service tunnels like twin shadows. Elara taught Julian how to read the masonry for hidden passages, and Julian taught Elara how to walk through a room so that the motion sensors would interpret her as a thermal drift.
There was a moment, in the crawlspace between the fourth and fifth floors, where the space was so tight they had to breathe in unison. Elara's forehead was pressed against Julian's chest. She could hear his heart—a steady, un-indexed beat.
"Why me?" she whispered into the dark. "Why did you keep the sketches?"
"Because," Julian said, his hands hovering just inches from her waist, "you were the only thing in this city that wasn't trying to be an image. You were just a fact. A beautiful, solid fact."
