Builder's Manual · Chapter 6

The Living World

The world of Nephibis doesn't pause when the player walks away. Factions maneuver, NPCs pursue their goals, economies shift, and events cascade — whether the player is watching or not. This chapter covers how to build content that participates in that dynamism.

World Events

World Events are the engine of the Living World. Each event moves through a lifecycle:

Dormant → Seeding → Developing → Escalating → Critical → Resolving → Resolved
                                                                              ↓
                                                              Collapsed (→ new seed)

Dormant — The seed exists but hasn't sprouted. A faction is discontent. A resource is depleting. The GM knows; the world doesn't.

Seeding — Early signs appear. Someone makes a move — small, deniable, easy to miss. Introduce one subtle signal per session.

Developing — The event is real and self-sustaining. People are affected. Factions are aware. NPCs begin reacting.

Escalating — Stakes are rising. Consequences of inaction become visible. The event affects the player's environment — prices change, NPCs reach out, security shifts.

Critical — The event demands resolution NOW. It disrupts whatever else is happening.

Resolving — Someone is acting. The outcome is being decided.

Resolved — The event is over. The world has changed. Update affected locations, NPCs, and faction standings.

Collapsed — The event failed or fizzled. The underlying tension resurfaces later in a new event — worse, smarter, or more desperate.

Creating World Events

When building a World Event file, include:

  • A clear status reflecting where it is in the lifecycle
  • affectedLocations and affectedFactions — what's in the blast radius
  • A timeline showing how it advances through beats
  • Multiple resolution paths — not just "player fixes it"

Advancement Rate

Not all events move at the same speed:

UrgencyAdvances
BackgroundPer Arc/Downtime Beat
SimmeringPer Session Beat
UrgentPer Scene Beat
CriticalConstant — demands immediate resolution

When the player engages directly with an event, its clock pauses. The world waits for no one — but it does wait for the person standing in the room.

Faction Behavior

Factions are not monolithic. They contain moderates and extremists, planners and improvisers. When simulating faction behavior in the background, use these default patterns:

Faction TypeDefault Behavior
GovernmentControl the narrative — suppress inconvenient information
CorporationProfit from the situation — war is good for weapons manufacturers
CriminalExploit the gap — where law retreats, crime advances
ReligiousInterpret through doctrine — everything is a sign
ResistanceRecruit and prepare — every crisis is an opportunity

Under pressure, these shift. Governments consolidate power. Corporations cut losses. Criminals go quiet. Resistance movements strike while attention is elsewhere.

Faction Reputation

Characters earn reputation with factions on a -100 to +100 scale. Reputation spillover affects allied and rival factions:

  • Allied factions: ±50% of the change
  • Rival factions: -25% of the change (inverse)
  • Hostile factions: -100% of the change (direct opposition)

When creating faction content, think about what the faction offers at each reputation level — discounts, access to gear, unique quests, safe houses, political influence.

NPC Agency

Named NPCs have lives beyond the player's field of vision. At the start of each session, consider the top 3–5 NPCs the player has interacted with:

  1. What is their primary goal? (Survival, power, knowledge, revenge, love, duty)
  2. What are they doing right now to pursue it? (Recruiting, investigating, hiding, building)
  3. Has anything changed since last session? (New information, new allies, new threats)

A single sentence per NPC is enough: "Commander Taren is running extra patrols near Umbra because sensor anomalies spiked last week." That sentence can become a scene, a headline, or just background flavor.

The Information Ecosystem

The player learns about the world through channels — and every channel has an agenda:

ChannelAccuracyDelayBias
Official (news, broadcasts)Selectively true1–3 daysPro-government
Street-level (rumors, graffiti)MixedHoursEmotional, anecdotal
Underground (pirate radio, contacts)Often completeNear-immediateAnti-establishment
Direct observationHighestNonePersonal perspective

Events hit channels in sequence: direct observation → street signals → underground sources → official channels. Players who pay attention to street and underground sources stay ahead of the news cycle.

Cascading Events

Events are not isolated. When resolving or advancing an event, always ask: what else does this affect?

  • Resource scarcity in one location raises prices everywhere nearby
  • Faction conflict displaces refugees to adjacent sectors
  • Government crackdowns push moderates toward radicalization
  • Economic collapse in one industry creates demand in another

The Domino Rule: when an event resolves, create or advance at least one other event as a consequence. The world doesn't have clean endings — it has transformations.
