Hook
A maze of shallow routes hides smuggler beacons and broken shrines.
Tahre Heart is a globe of island nations, reef chains, and sudden new shores where the sea moves to a hidden pulse. Most peoples live by ship, chart, and treaty, because roads are rare and every crossing depends on the Heart Tide. Magic is common, trade is fierce, and old burial customs still shape politics. When the pulse falters, ports, faiths, and crowns all feel it at once.
Themes
Form · Sphere
A sphere covered in island territories, reef chains, and broad seas, with no continent large enough to dominate the world.
Traversal
Travel is by sail, tide timing, and charted currents; the Heart Tide opens and closes routes across the globe, so the best roads are often temporary sea lanes.

The first sailors learned the Heart Tide, built harbor towns on the largest islands, and mapped the sea lanes that appear and vanish with each beat.
Merchant houses, sea lords, and temple courts fought over tolls, charts, and the right to name safe passages between islands.
After a chain of brutal island wars, the powers signed a peace that tied trade, burial rites, and ship passage to shared law.
The Heart Tide has begun to lag and surge, stranding fleets, waking old claims, and turning every harbor into a place of risk and leverage.
A fresh sandbar has risen between rival harbors, and both sides want it charted before the next tide swallows it.
A respected tidekeeper has vanished with the only full map of the next major pulse.
A privateer fleet offers fair pay to escort supplies, but their route crosses a forbidden grave current.
A string of villages reports the same drowned stranger arriving on different shores.
The world’s pulse was built by forgotten hands to keep the sea lanes alive.
Discovery · It shows up in lost tide tables and in the timing of sea-birds.

Impact · A hidden island is moving closer each year, and it may be the source of the pulse.
