Microscope: Chronicle Notes

System: Microscope: Chronicle (Playtest 2025) Author: Ben Robbins Status: PRIMARY history system for Western Horizon Use Case: Single-location history (settlement, object, organization)


Why Chronicle is Perfect for Western Horizon

The Scaling Insight

Chronicle for Lower TiersFull Microscope for Higher Tiers

The scope of what players need to know should scale with their tier and settlement size:

Tier 1-2 (Hamlet/Town):

  • Use Chronicle - Focus on THIS settlement’s history
  • Anchor characters are local: founders, early settlers, key NPCs
  • Periods span the settlement’s lifetime (decades, maybe a century)

Tier 3-4 (City/Capital):

  • Use Full Microscope - Zoom out to regional/world history
  • NEED to know: neighboring cities, kingdom structure, major conflicts
  • Periods span centuries, include multiple civilizations

What Chronicle Does

Creates the history of a single Chronicle (city, sword, secret society) through the lives of Anchors (characters connected to it).

Core Difference from Standard Microscope

MicroscopeChronicle
Entire civilization/worldSingle thing (city, object, org)
Broad, sweeping historyPersonal, character-focused
Can lose focusStays tightly focused
Good for Session Zero worldGood for settlement history

Chronicle Procedure (Abbreviated)

Setup

  1. Pick Our Chronicle — The thing you’re creating history for
  2. Bookends — START Period and END Period (each Light or Dark)
  3. Palette — Yes/No lists for tone and content
  4. End Discussion — No coaching on others’ turns
  5. First Pass — Each player makes one Period or Event
  6. Second Pass — Each player makes one Event or Anchor

The Three Elements

Periods — Major chunks of time (years, decades, centuries). Light or Dark.

Events — Specific things that happen within a Period. Complete description with outcome.

Anchors — Named characters tied to specific Periods. Show the Chronicle through their eyes.

Integration with Street Magic: Anchors from Chronicle → Residents in Street Magic (add sensory details and vignettes)

Integration with Western Horizon

When to Run Chronicle

TierWhenDuration
Tier 1 (1-4)At founding or reaching Tier 21-2 hours
Tier 2 (5-10)When established or reaching Tier 32-3 hours
Tier 3+ (11+)Switch to full Microscope2-4 hours for Chronicle of specific locations

Handoffs to Other Systems

  • Chronicle creates → Ex Novo details (founding periods → districts, resources)
  • Chronicle creates → Street Magic details (Anchors → Residents with true names)
  • Chronicle creates → Beak, Feather & Bone details (events → headquarters buildings)
  • Chronicle creates → Ex Umbra hooks (sealed temples → rumor-based dungeons)

Key Modifications for WH

  1. Abbreviated Chronicle: Set Period target (3-5 for small, 5-8 for larger), time-box sessions
  2. “Current State” as END Bookend: END isn’t destruction—it’s where the settlement is NOW
  3. Living Chronicle: Can be reopened at later tiers, END bookend shifts
  4. Integrate with Palette: Use Palette step for campaign tone + safety tools

The Tiered Approach Summary

  • Tier 1-2: Chronicle for settlement history (local scope, 1-3 hours)
  • Tier 3+: Full Microscope for world history, Chronicle for specific locations
  • Session Zero: Optional Microscope for world → Chronicle for starting settlement
