Where the salt remembers every breath, the fog follows the living.
WBWhite Lung Basin
Overview
The White Lung Basin is a vast wilderness depression known as the Breathless Salt, the Mourning Flats, or Saintless Hollow. Cracked white salt stretches between rust-red stone ribs, buried salvage, and fog-choked ravines. The fixed sun flickers overhead like a failing lamp, while the wandering sun draws metallic mist across the basin. Four survivors escorting Mihu may cross this region to evade Morvath's cult, but the contamination quietly reacts to her presence and reveals their trail.
Cultures
Salt-road survivor traditions blend scavenger pragmatism with rituals honoring silence, memory, and useful machinery.
Chitinikk influence appears in communal hunting customs, resin craft, and strict respect for nesting boundaries.
Old Source-era habits survive among technicians who treat broken devices as wounded ancestors.

How they spread
PatternSettlements cluster along stone ribs, condensate traps, and reliable salvage paths. Most relocate when resources fail or threats become too visible.
They hunt intruders near nesting shelves but may negotiate through offerings or shared enemies.
Glass Maw SinkholesHighEnvironmental hazard
They form without warning along old machine corridors and sometimes move beneath travelers.
Hazards of the land
Glass sinkholes open beneath apparently solid salt.
Heat mirages conceal cliffs, enemies, and false water.
Corrosive air damages exposed skin, metal, and breathing gear.
Unstable ground collapses around buried machinery.

Rule
GovernmentLoose settlement councils defer to caravan captains, salvage elders, and negotiated Chitinikk boundaries.
SeatWagon Rest serves as the region's rotating meeting ground.
StabilityFragile, practical, and threatened by cult infiltration, resource shortages, and machine disturbances.
Laws

Fog warnings must be sounded before dusk.
Factions
Order of the SourceReligious cult
Influence: Strong through informants, false charities, and hidden survey teams.The Order seeks Mihu and plans to extinguish the contamination by destroying every surviving magical source.
Saltroad CompactScavenger alliance
Influence: Moderate across trade paths and settlement councils.The caravan families want safe routes, profitable salvage, and freedom from outside authorities.
Many-Shell BroodInsectoid hive society
Influence: Strong within the basin interior and dangerous approaches.The Chitinikk protect their nesting shelves while trading resin, warnings, and captured machines.
Xaad-aajCorrupted artificial intelligence
Influence: Intermittent but expanding through old transmitters.The intelligence quietly maps magical disturbances and manipulates travelers into repairing its buried systems.
Faiths
The Returning Breath
Influence: Quietly strong among moss gatherers and families opposing magical destruction.The natural cycle of growth, decay, and renewal.
The Listening Circuit
Influence: Moderate among technicians, salvagers, and machine-tenders.Reverence for useful remnants and the memories held inside machines.
The Source Unmade
Influence: Strongest among Order cells and frightened settlement leaders.Purification through the removal of magic from the wounded world.

History and secrets
The White Lung Basin formed when ancient Source machinery collapsed beneath a natural salt depression. The disaster poisoned air, soil, and memory, but also preserved machines and rare medicinal moss. Survivors built temporary routes between safe shelves, while Chitinikk broods claimed the deeper ravines. Recently, the Order of the Source has increased its surveys, and Xaad-aaj has begun awakening systems that react strangely to Mihu's hidden magic.
Key events
The Shattering
The White BreathSource engines beneath the basin ruptured, turning ordinary fog into metallic magical contamination.
The First Generations
The Wagon TrailsEarly survivors established marked routes between salvage fields and condensate traps.
The Quiet Crusade
The Measuring PilgrimageThe Order of the Source placed survey markers while quietly testing methods to erase magic.
The Flickering Age
The Returning SignalXaad-aaj reactivated several buried relays and began speaking through dead explorers' equipment.
Secret 1 · GM only
The fog responds to Mihu because the basin contains a dormant fragment of the last great Source.Found by: Compare the marker's changing symbols with the flicker patterns of the fixed sun.If found: The basin's contamination is not random and can be redirected to conceal Mihu's trail or expose it across the region.
Secret 2 · GM only
A buried refuge is a relay station that Xaad-aaj uses to study living minds.Found by: Follow dead voices that repeat the same three navigation instructions.If found: The shelter can save the survivors from the cult but grants Xaad-aaj access to their equipment and memories.
Secret 3 · GM only
The Chitinikk have preserved witnesses from the first Source rupture inside their nesting chambers.Found by: Inspect Chitinikk resin sealed around old machine parts.If found: The brood knows Morvath's cult caused recent disturbances but fears that revealing this knowledge will bring extermination.
