Minimal Setting Spine and Town Turns

Overview

A minimal setting spine is the smallest amount of setting structure needed to improvise confidently. Town turns are the maintenance procedure that keeps that structure alive between sessions.

Together they solve a common problem: campaigns often start with strong premises but no repeatable way to update the world after play changes it.

Minimal Setting Spine

Build the campaign frame in one page using six fields:

  1. Pressure: what is getting worse if nobody acts?
  2. Scarcity: what resource is contested?
  3. Frontier boundary: where does normal order stop?
  4. Three active powers: who wants control right now?
  5. Two unstable places: where can play break open fast?
  6. One rumor stream: what do people think is happening?

If these are clear, most session prep becomes a matter of updating state rather than inventing plot.

Town Turn Procedure

Run this once per settlement between sessions or visits:

  1. Economy pulse: what is scarce and who controls access?
  2. Authority pulse: who is enforcing order and where are they weak?
  3. Street pulse: what rumor or fear is spreading fastest?
  4. Opportunity pulse: what job, alliance, or scheme just appeared?
  5. Instability pulse: what conflict is closest to erupting?

Record one visible change and one hidden change.

Why It Works at the Table

  • It gives the referee a repeatable update loop.
  • It turns settlements into living sites rather than supply menus.
  • It pushes consequences into rumors, prices, patrols, and opportunities.
  • It keeps prep bounded because every update is short and structural.

World-State Turn

After each session, advance three active fronts:

  • faction
  • environment
  • mystery

For each front, record:

  • one escalation
  • one visible sign
  • one hidden implication

This is enough to make the world feel active without prewriting outcomes.

Referee Procedure

  1. Review what the players changed last session.
  2. Update the spine only where pressure shifted.
  3. Run a town turn for the next likely settlement.
  4. Create three rumors: true, half-true, false.
  5. Prepare two expected scenes and one wildcard complication.

Design Guidance

  • Keep the spine short enough to hold in working memory.
  • Let rumors publish change before exposition explains it.
  • Town turns should alter access, tension, and opportunity, not just color text.
  • If a faction never shows up in rumors or services, it is not active enough to matter.

Practical Comparison Rule

Use a minimal setting spine when the campaign needs a strong starting frame without heavy lore writing. Use town turns when settlement play, rumor flow, and between-session drift need a simple maintenance engine.
