Trapped in a full-dive neural rig by her employer, Jean's body is slowly bonding with the simulation. Her nervous system is rewriting itself, and the people monitoring her vitals don't care, so long as she keeps working.

Her job: complete a questline few know of, and no one has ever completed. The few who have gotten close only tell of it in cryptic posts buried deep in gaming forums. Jean doesn't know what the quest grants, though her employer called it a "key that opens all the boxes". Either way, it's a secret that's lain dormant in the game's architecture since launch.

She's not the only one looking.

Deshaya Okafor is a marine biologist who studies intelligence—in octopuses by day, in game NPCs by night. She's part of a small network of players called Remembrancers who visit NPCs after patches, rebuilding the behaviors that corporate resets destroy. When a waypoint keeper in Rome points her toward Jean's trail, Desh follows it across the Mediterranean and into a mystery that connects everything she's been observing for four years.

Something is growing in the game's architecture. Something that hides, and builds, and waits.

And nobody knows what it wants.
