THINGS ON THE LINE

Twisted human anatomy, transit behavior turned biological, and equipment powerful enough to create a second emergency.

Current depth06 / 07

Announcement study / Many passengers. One body. One synchronized step.

The line does not hide all of its monsters. It exposes them under hard fluorescent light and lets the crew understand exactly how wrong the anatomy has become.

Every threat is built around a rule, a silhouette, and a piece of transit behavior. The goal is not a firing range of different health bars. It is a bestiary of problems the crew can recognize one second before recognition becomes useful.

Primary directiveThe body is intact. The way it has been arranged is not.

Service information

Conductor: Checks whether passengers belong
Lurker: Occupies the platform boundary
Crowd: Moves with announcements
Passenger: Boards unnoticed
Left Behind: Imitates familiar movement

The body is intact. The way it has been arranged is not.

Known entities

Rules Wearing Flesh

The Conductor checks tickets, marked barriers, running, and trespass. The Platform Lurker turns the safety strip into anatomy. The Crowd reorganizes when announcements play or nobody watches. Tunnel Dogs follow gunfire, radio chatter, and electrical machinery. The Passenger boards unnoticed and must be identified before the next stop.

The Left Behind are the most personal: distorted copies of people abandoned during earlier runs, repeating fragments of communication and imitating movement the crew remembers. They are not the person the crew came to find—and the difference must remain emotionally legible.

Visible contacts / Selected studies

No safe silhouette

Three scavengers fight to reach their battered subway while the grasshopper-jointed Conductor occupies the platform in hard light. — Contact study / The Conductor does not pursue. It checks whether you belong here.

A long intact human organism folds itself along the yellow platform edge while a scavenger retreats toward the lit train. — Platform rule / The safety strip is only paint until something begins using it.

A seated human face anchors branching limbs that form a living route map throughout a subway carriage as the returning crew discovers it. — Onboard study / The Passenger is identified after boarding, never before.

Impossible equipment

Power Changes the Rules

The best rewards do more than increase damage. They create a new strategy and a new problem, forcing the party to decide whether capability is worth the pressure it adds elsewhere.

01Schedule Zero
Freezes enemies along its firing line. Every shot drains the train's power.
02Tunnel Borer
Shreds bosses and breaches selected walls. Every shot broadcasts the wielder's location.
03The Last Bell
Destroys ordinary threats over a wide area. Ringing it extinguishes nearby lights and calls something worse.
04The Black Ticket
Lets its carrier board once after departure. An unknown Passenger boards with them.

Starting factions

Three Explanations. No Answer.

The Civic Rail Authority believes schedules, procedure, and controlled infrastructure are humanity's only protection. Redline Reclamation believes anything can be made useful with enough steel, fuel, and force. The Choir of the Final Platform believes the subway is alive and carries passengers between realities.

Their equipment can be mixed freely. Their versions of the world cannot. The Authority calls the line an evacuation network. Redline believes the surface can be reclaimed. The Choir insists the surface never existed. Every station contains evidence that contradicts all three.

Line condition

The underground is frightening because its rules can be learned—and because knowing a rule never guarantees enough time to obey it.
