Sereia

Every safe harbor is someone else's claim, and every horizon asks for a sail.

Overview

Sereia is a warm, island-strewn sea where independent ports cling to fertile shores and steep green hills. Ships carry olives, salt fish, pottery, and news between familiar harbors, but beyond the marked passages lie reef mazes, volcanic islets, and long crossings where weather decides who returns. Every community depends on the sea and fears its price. Now poor harvests and uncertain charts are testing old agreements, and even a small crew can change the balance between islands.

The world

ShapeA round world
What it is likeA spherical world whose inhabited lands form a broad, irregular archipelago across a warm sea, with several large islands, scattered chains, reefs, and wide stretches of open water.
How people travelTravel is by sail and oar, following seasonal winds, sheltered channels, and known harbors; open-water crossings demand provisions, capable pilots, and luck with the weather.
Themes
  • Mythic maritime adventure
  • Island rivalries
  • Exploration and uncertain maps
  • Hard-won hospitality

Laws of the world

The rules

MagicMagic is scarce and practical: vows, offerings, and carefully kept rites may bring a favorable wind or a warning dream, but never reliably command nature.
TechnologyPrimitive tools, bronze and iron blades, pottery, woven sails, and sturdy wooden ships; no reliable way to cross the open sea without sail or oar.
Death and soulsThe dead are buried or burned according to local custom; people say a soul follows the last tide it saw, but no confirmed spirit has returned to prove it.

Special rules

Oaths sworn before a harbor altar are binding in law even when their magic is doubted.
Fresh water is precious enough that wells and cisterns are protected as common civic trust.

The skies

SkiesClear days turn the sea bright turquoise, while humid evenings bring violet cloudbanks and sudden squalls; sailors read stars through gaps in the clouds.
Moons and stars

the Sun, the Moon

SeasonsThe year turns through a dry sailing season and a wet season of heavy rain and rough crossings; communities count days by sunrise and mark months by the Moon.

Ages

3 ages
Several dry years and a run of violent storms have strained island stores, while old charts disagree about reefs and the city-states dispute access to dwindling freshwater.
