Chapter 2 — Ignition

The Opening Narrative

You have read this opening already. It is how this book began — Kael, the corridor, the marks in the wood, the question left hanging. Read it once more, and this time watch it as a thing that was made:

The north corridor of the safe house is cold and close to silent. Kael stands with his hand near the latch of a door he has not yet opened, three pale cuts in the old wood just above his fingers. Beyond it, somewhere, is the ledger — the one that names everyone who ever ran with him. The house was built by people who expected betrayal; he has already passed two doors that were not what they pretended to be. The watch are due back before light, and the dark outside the one high window is already thinning. He does not quite trust the quiet. He looks at the marks in the wood above the latch. What are they?

Every solo session worth watching opens on something like this. Not a character sheet. Not a list of objectives. A person, in a place, with a problem closing on them, and a question they can’t yet answer. That is what people mean when they say a session had life from the first minute.

It is not talent, and it is not free writing. It is the output of a procedure called Ignition, and every clause in that paragraph came from a specific step. Watch the seams:

a thief who reads small signs, in a house built to punish the careless → the Hook

the ledger — beyond the door, somewhere → the Aim

doors that were not what they pretended … the watch due before light → the Friction

the one that names everyone who ever ran with him → the Stake

the north corridor, the hour before dawn, every door a possible trap → the Stage

He looks at the marks. What are they? → the Opening Beat’s First Question: where play begins

It reads like prose. It is assembled like a machine. And here is the thing worth noticing before anything else: Kael did not invent any of that. He is playing a module. The house, the ledger, the people who built the place expecting betrayal, the watch and their schedule — all of it was on the page. His Ignition didn’t author the situation. It read the situation off the module and narrowed it to a person at a door with a question.

How much of this do you need?

As much or as little as the situation doesn’t already hand you. Ignition is not a gate you pass through before you are allowed to play. It is a set of tools for one job: deciding where the fiction comes from.

If your setting already provides a strong opening — a module’s call to action, an inciting incident, a faction making demands — you may not need all three parts. Start at Problem Setup. If the situation still feels flat, work back to the Hook. Take the tools the moment is missing and leave the rest. The only output that is not optional is the last one, and we will come to why.

Where the fiction comes from

Kael read his Ignition off a module. Now watch the same procedure run with no module at all.

Sam has no scenario tonight. No prepared adventure — just a character she knows and a setting she knows: an occult investigator allied to the French Resistance, occupied France, 1943. She is playing generatively. We will operate the procedure on her, step by step, because the steps are clearest when nothing is handed to you and you have to source every part yourself.

This is the whole relationship between scenario play and generative play: it is the same Ignition. The steps do not change. The only difference is where each part is sourced. Kael read his Friction and Stage off the page. Sam imports hers from the setting and the character sheet. Same statement out of the other end. None of it is invention for its own sake — all of it is sourcing.

The Hook

Sam starts with herself, not the mission. She looks at her character sheet and picks one thing that feels real right now: Occult Lore. She asks what that detail implies about the world — if she has occult knowledge, then the world has things worth knowing it about: dangerous relics, sealed away by people who understood what they were dealing with. Then she asks what is happening now that makes it matter. Resistance intelligence has located one. The Silver Sword. In a cathedral vault in Reims.

Her Hook:

“If I have Occult Lore, then the world has dangerous relics. Right now, Resistance intelligence has located the Silver Sword.”

That is the whole step, and now it has a name. A Hook connects one detail from your character sheet to one fact your setting must therefore contain, then says why it bites today. Two moves:

Anchor — “If I have (detail), then the world has (implied fact).”

Trigger — “Right now, ___.” An arrival, an escalation, a deadline, a reveal, a disruption, a loss.

One discipline, and it is the system telling you no. If your Hook names the objective — steal, find, retrieve, kill — that is your Aim bleeding in. Strip it out and go back to the sheet. The Hook is about who you are, not what you have to do. The moment the mission sneaks in, you have skipped the only step that keeps the opening about a person. (Kael’s held the line too: a thief who reads small signs — who he is — not “get the ledger.”)

A detail is anything on the sheet. A skill: “If I have Stealth, the world has problems that reward not being seen — right now the patrol routes have changed.” A contact: “If I have a fence in the docklands, stolen goods move through channels I know — right now something I fenced has surfaced in the wrong hands.” Even an absence: “If I have no healing magic, the world has healers who charge what they like — right now the only healer in the valley wants a favour, not coin.”

Your turn. One detail that feels real. The world fact it implies. The thing happening now that makes it matter. If the objective sneaks in, you have written the Aim — go back.

Problem Setup

The Hook gave Sam a situation. Problem Setup makes it playable by answering four questions — and you watch her sharpen each one until it has teeth.

What does she need right now? Not the war, not the campaign — tonight. To steal the Silver Sword. That is the Aim.

What resists it? She looks at the setting and imports, she does not invent: the vault is sealed by a consecration ward; Wehrmacht patrols sweep the grounds every ten to fifteen minutes; the Gestapo are arranging the Sword’s transfer, so it has to be tonight. She sharpens with one constraint — before sunrise. That is the Friction:

“Right now, I’m trying to steal the Silver Sword, but it’s sealed in a vault, before sunrise, while Wehrmacht patrols sweep the grounds.”

What does she personally lose if she fails? Not what the war loses — what she loses. If she fails, she is caught and interrogated, and the Resistance network in Reims is compromised. Notice the Stake came out of the Friction, not the Aim. The best ones usually do.

Where is this, when, and what does the place actively do to her? Reims Cathedral, winter 1943, midnight, mid patrol-sweep — and fresh snow over the graveyard, turning every step into evidence. That last detail is not atmosphere. It is a machine that converts movement into proof.

Now the steps have names:

Aim — one shape: Recovery, Protection, Acquisition, Investigation, or Obligation. “Right now, I must ___.”

Friction — “I’m trying to (Aim), but (Friction),” sharpened with one constraint: without (a resource you can’t use), before (a deadline), or while (a complication already running). One is enough; two is richer.

Stake — “If I fail, ___.” Concrete and personal. Loss, Escalation, or Exposure. “Something bad happens” is not a Stake. “The cartel silences my contact, for good” is.

Stage — “At (place), (when), while (active constraint).” The test: can the place notice you, interrupt you, or make the goal harder? If it can’t, add until it can.

And here is the one place in all of Ignition where the dice push back. If you cannot find an active constraint for your Stage, you do not invent one — you roll for it. Roll d6, halve it (round up), for how many constraints; then roll that many d12:

1 Patrols / security sweeps

2 Witnesses / crowds / bystanders

3 Timer / countdown / closing window

4 Weather / elements (rain, snow, heat, fog)

5 Darkness / low visibility / smoke

6 Noise / alarms / loud environment

7 Limited access (locked doors, checkpoints, ID)

8 Fragile ground (creaking floors, thin ice, loose rubble)

9 Hazardous terrain (cliffs, ledges, deep water)

10 Unstable situation (riot, fire, evacuation, collapse)

11 Competing faction on-site (rivals, inspectors, cultists)

12 Surveillance / scrutiny (cameras, scrying, informants)

It is buried at the bottom of a step, but do not treat it as a last resort for the uninspired. It is the only moment in Ignition where the game hands you something you did not choose — a constraint you now have to play around rather than one you reached for. That is worth reaching for, not just falling back on.

Your turn. Aim in one sentence. Friction with at least one constraint. A Stake that names something concrete you personally lose. A Stage that can push back — rolled, if nothing presses. Does the whole thing make you feel something — urgency, dread, defiance? If not, sharpen until it does.

The Opening Beat

Problem Setup describes the situation. The Opening Beat puts Sam inside it.

Where is she standing, physically, right now? Not “Reims Cathedral” — that is the setting. Crouched behind the low stone wall on the east side of the graveyard, within reach of the Aim, in contact with the Friction. That is Position.

What does she attempt? Not a plan — one physical thing. She presses to the stone and scans for a route across that keeps her off the open snow. That is the First Action.

What is uncertain at the edge of it, asked from inside her, not from above? Not “is there a patrol?” but “what do I see when I look across the graveyard?” That is the First Question — left unanswered, on purpose. It is where play begins.

Written as one paragraph, present tense, eye-level, ending on the question:

Midnight frost grips the graveyard at Reims Cathedral. Sam crouches behind the low stone wall on the east side, breath visible in the cold. The Cathedral looms ahead — the Silver Sword is somewhere inside, locked in a vault she hasn’t seen. Fresh snow blankets the graves between here and the nearest door, and beyond the wall she can hear the rhythm of a patrol sweep working the grounds. Sunrise is hours away, but not enough hours. She presses against the stone, scanning for any route across the graveyard that might keep her off the open snow. What does she see?

That paragraph is the statement: Position, First Action, First Question, sourced from a Hook and a Problem assembled one piece at a time. It was never free writing — and that is exactly what Kael’s opening was too, run the other way: read off a module instead of imported from a setting, same machine, same shape out the end.

Your turn. Write your Opening Beat — one paragraph, present tense, eye-level, ending on your First Question. That paragraph is your statement. The opening narrative you would lead your session with. You did not write it. You built it.

Back to Kael — and the latch

You have now operated the machine. Watch it close. Kael’s Ignition runs the same four moves you just learned, sourced from the module instead of imagined — assembled, not reconstructed here for the first time:

Hook If I read small signs, then the world has rooms built to punish the careless. Right now, a house built by people who expected betrayal stands between my crew and the thing that can hang them.

Aim Get the ledger out of the safe house.

Friction The house is trapped by people who expected exactly this, and the watch return before light.

Stake If I fail, the ledger stays — and it names everyone who ever ran with me.

Stage The safe house’s north corridor, the hour before dawn, every door reinforced or trapped, the watch due back before light.

Opening Beat At the latch of an unopened door, three pale cuts in the wood above his fingers. What are they?

One thing left, and it is the only part of Ignition you do not get to take or leave. Read Kael’s statement and ask what his character is actually driving at: get the ledger out before the house and the watch close on him. That want — stated by the character, not the player — written down as the thing play will press on, is the Pressure Clock. Name it as the question he is asking — the north star, never the action and never the how; it does not matter whether he picks the latch, forces it, or goes through a window. Pick the scope that helps you, from this one corridor to a whole campaign; default size 4; and write it as a question, the one form a reader cannot mistake for a progress bar. Kael writes:

Can I find the ledger? 0/4

Everything else in Ignition was dialable — as much or as little as the night needed. This is not, because this is the one output the rest of the system consumes: the next chapter’s engine fills this clock, and there is nothing to fill if you never named it. It is not a counter bolted onto the fiction. It is the character’s want, made trackable. The statement was character. The clock is that character, given something to lose ground against.

So here is where Ignition leaves Kael:

The north corridor of the safe house is cold and close to silent. Kael stands with his hand near the latch of a door he has not yet opened, three pale cuts in the old wood just above his fingers. Beyond it, somewhere, the ledger. The watch are due back before light. He does not quite trust the quiet. He looks at the marks in the wood above the latch.

The question is unanswered. It is supposed to be. His clock is named. From here you take the first roll — and the next chapter is what that roll does. The opening you read at the top of this chapter was the destination. You now know the road, and Kael’s hand is still on the latch.
