Moth

Every promise has a weight, and someone keeps the scales.

Overview

Moth is a globe of busy trade roads, lamp-lit cities, and small communities that depend on public scales to make distant promises trustworthy. The Great Weighing linked local measures into one magical standard, allowing goods, taxes, and even civic duties to be counted across continents. Now the standard gives contradictory answers. Merchants argue over whose measure is true, while ordinary people discover that a faulty entry can change what their town owes, owns, or is allowed to remember.

The world

ShapeA round world
What it is likeMoth is a single inhabited planet with familiar continents, oceans, and a slightly larger-than-Earth circumference.
How people travelShips follow coasts and established ports, while caravans use beacon-marked roads; high passes and unlit stretches make overland travel slow and risky.

Laws of the world

The rules

MagicMagic responds strongly to measured exchange: weight, distance, time, and freely witnessed promises can shape spells, while false measures make effects unstable.
TechnologyMagitech is common in cities and along trade roads, built around brass scales, relay lamps, and pressure-driven lifts; rural communities repair older devices with salvaged parts.
Death and soulsSouls pass beyond the world after death, though a person's recorded promises can remain bound to a civic scale and trouble heirs until resolved.

Special rules

A sworn agreement made before a working public scale can be enforced by subtle magical pressure, but not compelled to succeed.
Beacon lamps attract moths and other creatures, including some that carry spell-charged dust.

The skies

SkiesA broad blue sky is often hazed by the amber glow of enormous beacon lamps; moths gather around their light in clouds visible from the high passes.
Moons and stars
  • The Sun
  • the pale moon
  • the wandering red star called the Nail
SeasonsThe year has four familiar seasons, but civic calendars follow the monthly relighting of the great lamps, when contracts are renewed and debts publicly weighed.

Ages

3 ages
A growing number of official records disagree with lived experience, and the machinery that once settled disputes now creates them.

Conflicts

  • The Measure Dispute
    Sides

    If the shared standard fails, trade and public protections may collapse; if it is enforced unchanged, whole communities may be declared legally nonexistent.
  • The Lamp Riots
    Sides

    the lamp keepers, urban residents, raiders from the outer roads

    The moth-drawing beacons keep roads safe but consume scarce fuel and draw raiders toward the settlements they protect.
