The Common Measure

In this land, a line becomes real when enough people agree to keep it.

Overview

The Common Measure is a settled world where the most powerful magic is the act of agreeing where a thing begins and ends. A shared boundary can protect a village, but it can also make a landlord's claim stubbornly real. For generations, the Great Survey's calendar and maps have kept trade moving between farms, ports, and market towns. Now a new census threatens to erase old rights, while those who feed the realm argue over who gets counted, taxed, and remembered.

The world

ShapeA round world
What it is likeA temperate, inhabited planet of broad continents, with the Common Measure's main campaign lands clustered around a navigable river and its neighboring coasts and uplands.
How people travelTravel by cart on maintained roads, by boat along the river, or on foot over local tracks; official maps are useful, but disputed boundaries can make routes politically dangerous.
Themes

grounded fantasy, custom versus law, resourceful communities, political adventure

Laws of the world

The rules

MagicMagic is uncommon and practical, worked through careful knots, spoken measures, and offerings tied to a place; it can influence weather or memory but never command either outright.
TechnologyLate medieval tools, water mills, sailboats, and simple black-powder signal tubes are known; long-distance travel relies on horses, carts, and river craft.
Death and soulsThe dead are believed to pass beyond the Moon's reach; burial customs differ, but no reliable spirit has returned to settle the question.

Special rules

A boundary witnessed by three households is difficult to move by force or magic.

The skies

SkiesClear skies are common, with high cloud bands used by farmers to guess the coming rains.
Moons and stars

SeasonsThe Great Survey calendar divides the year into twelve months, though planting and harvest still follow local signs.

Ages

A new census promises fairer rations, but its maps mark uncultivated land as vacant and threaten communities that have lived there for generations.
