The Rust Oasis of the Salt Flats

Where Water Is Blood and Scrap Is Sovereign

By Alex Merced · Published 2026-08-03 · Online Supplements

In the blinding, sun-scorched expanse of the Great Salt Flats sits Iron-Well, a fortified trading post built around a ancient geothermal water purifier. Surrounded by thousands of miles of dead salt desert, Iron-Well is the only source of drinkable water for five hundred miles. Survival requires balancing water rations, defending the solar stills from marauder war-bands, and scavenging ancient pre-collapse technology buried beneath the salt crust.

Core Mechanic: Hydration Depletion: Track the crew's water reserves as Hydration Depletion from 0 to 6. Environmental heat, physical exertion, and desert travel increase Depletion. At Depletion 4, characters suffer physical check penalties. At Depletion 6, severe heatstroke incapacitates the character.

“One liter of purified water buys a day of life, a handful of machine bolts, or ten minutes inside the shade-domes. Don’t waste a drop.”

1. Setting Overview and Tone

The Great Salt Flats were once a thriving inland sea, now dried into a blinding, white desert under a merciless sun. Iron-Well was constructed out of rusted shipping containers, scavenged tanker trucks, and solar stills anchored to a central geothermal deep-well pump.

Tone: Gritty, brutal survival, mad-max wasteland aesthetic. High tension around resource scarcity, harsh environmental hazards, and desperate moral choices.

Sensory Pillars:

  1. Sight: Blinding white salt reflecting harsh sunlight. Rusted iron towers against a cloudless cyan sky. Dust-rig vehicles with spiked tires.
  2. Sound: The rhythmic, groaning thump of the geothermal water pump. The howling desert wind whipping salt dust against metal plating. The crackle of desert radios.
  3. Touch and Smell: Salt-caked skin. The burning heat of exposed metal. The sweet, metallic taste of purified well water.

2. The Wasteland Landmarks

The Wellhead: The central geothermal pump room, guarded 24/7 by heavy turrets.

The Scrap Bazaar: A chaotic market under stretched canvas sails where scavengers trade pre-collapse tech for water chits.

The Salt Wastes: Miles of cracked white crust hiding sinkholes, unexploded warheads, and marauder ambush posts.

3. Factions

The Wellkeepers: The ruling junta of Iron-Well who control the water supply and enforce strict rationing laws.

The Sun-Warriors: A violent warlord faction driving motorized scrap rigs, seeking to seize the well for themselves.

The Dune Crawlers: Nomadic scavengers who harvest pre-collapse ruins buried deep in the salt crust.

4. Unique Mechanic: Hydration Depletion

Track Hydration Depletion from 0 to 6.

Depletion Triggers:

  • Travel through Salt Wastes without shade: +1 Depletion per hour
  • Intense combat or physical exertion in heat: +1 Depletion
  • Consuming a ration of purified water: -2 Depletion

Depletion Levels:

  • 0-1: Fully hydrated. Optimal physical condition.
  • 2-3: Mild thirst. Chapped lips, slight fatigue.
  • 4-5: Severe dehydration. Disadvantage on physical Force and Finesse checks.
  • 6: Heatstroke collapse. Incapacitated until rehydrated.

5. Character Archetypes

The Rig Driver

You pilot a heavily armored scrap vehicle equipped with harpoons and reinforced bumpers.

  • Drive: “Keep the rig running and convoy routes open.”
  • Approach Distribution: Force 2 | Finesse 2 | Mind 1 | Presence 2

The Salt Scavenger

You know how to read the salt crust, avoid sinkholes, and unearth pre-collapse technology.

  • Drive: “Find the motherlode pre-war tech cache buried beneath the salt.”
  • Approach Distribution: Force 1 | Finesse 3 | Mind 2 | Presence 1

The Well Technician

You maintain the ancient geothermal pumps and water purification filters.

  • Drive: “Keep the water flowing and prevent pump filter contamination.”
  • Approach Distribution: Force 1 | Finesse 2 | Mind 3 | Presence 1

6. Starter Scenario: The Filter Contamination

The main purification filter at Iron-Well begins failing, tainting the water supply with sulfur and toxic minerals. The only replacement filter unit is located inside a submerged pre-collapse research bunker fifteen miles into Sun-Warrior territory.

The players must outfit a scrap rig, navigate the treacherous Salt Wastes, breach the bunker, and return with the replacement filter before Iron-Well’s stored water runs out in forty-eight hours.
