Where the roots hide treasure and the tide remembers every trespass.
TGThe Drowned Green
Overview
The Drowned Green is a broad wilderness of small jungle islands and mangrove-lined waterways near Davania. Brackish channels wind beneath tangled roots, crossing mudflats, flooded hollows, and reed-choked pools before reaching open sea. Salt-heavy air, luminous insects, sudden rain squalls, and shifting tides shape every journey. Boaters, monsters, salvagers, and wary guides share this maze, where larger mangroves hide old rope scars, buried evidence, and caches that still tempt explorers.
Cultures
Tideway boaters who treat currents, kinship, and hospitality as sacred obligations.
Jungle island clans who gather medicinal plants, shellfish, resin, and saltwater herbs.
Wreck-descended traders who blend distant customs with local survival practices.

How they spread
PatternSettlements cluster on stable island edges, old dock sites, and channel junctions, while remote waterways remain nearly uninhabited. Small homes often stand on stilts or movable platforms.

Power
Rule
GovernmentA loose coalition of boaters, island elders, herbalists, and trade representatives governs through seasonal councils.

History and secrets
The Drowned Green was first settled by clans who learned to read tides, fog, roots, and storm signs as carefully as written maps. Later traders used its channels as shortcuts, but several expeditions vanished and left behind abandoned camps, faded markings, and concealed caches. The Tidewardens now preserve fragile agreements among residents, while outsiders increasingly search the old trees for forgotten cargo and dangerous secrets.
Key events
Before written records
The First Tide MapsEarly island clans mapped the channels by carving tide marks into durable mangrove roots.
Several generations ago
The Lost FlotillaA trading flotilla vanished during a storm, leaving campsites, abandoned canoes, and rumored treasure caches.
Recent generations
The Channel CompactThe Tidewardens formed after rival salvagers caused a deadly channel blockade during a falling tide.
Recent years
The Cache HuntUnknown searchers began cutting old ropes and probing larger mangrove trees for hidden compartments.
Secret 1 · GM only
The old caches were part of a covert supply chain used by survivors of the Lost Flotilla.Found by: A cache tree bears rope scars that continue beneath the waterline.If found: The hidden network connects several islands and reveals that the Lost Flotilla survived longer than recorded.
Secret 2 · GM only
The markings identify a protected breeding ground shared by local clans and territorial monsters.Found by: The faded territorial markings overlap older clan symbols in a pattern visible only at low tide.If found: Revealing the pattern could prevent a creature war or expose a disputed ancestral claim.
Secret 3 · GM only
Someone is looking for an artifact capable of predicting or manipulating the deepest tides.Found by: Fresh tool marks appear inside a sealed compartment containing no treasure.If found: The searchers are pursuing a map or key that could redirect the region's waterways.
