Under the Dome: Grind (A D&D resource from a post apocalyptic fantasy setting)
Fuel, Currency, and Control in a Post-Apocalyptic D&D Campaign
In Under the Dome, survival runs on a single substance:
Grind.
Every light that flickers back to life after a storm.
Every engine that roars across a broken district.
Every desperate deal made in shadowed alleys.
It all traces back to the same source:
Refined chaos. Crystallized survival.
Grind isn’t just a resource.
It is the foundation of power under the Dome—and the reason that power is never stable.
🌩️ 1. Where Grind Comes From
Grind begins in the worst possible place:
the aftermath of chaos storms.
When storms tear across the wasteland, they leave behind:
-
Jagged crystal growths
-
Unstable energy deposits
-
Fields where reality hasn’t fully settled
These raw crystals are volatile, unpredictable, and incredibly valuable.
Harvesting them requires:
-
Specialized scavenger crews
-
Heavily modified vehicles
-
Or people desperate enough to try without either
Many scavvers never return.
Those who do are rarely unchanged.
🏭 2. Refinement: Turning Chaos into Control
Raw crystals are unusable—and often lethal—without refinement.
Inside the Dome, Grind is processed through:
-
Guild-controlled refineries
-
Baron-owned industrial complexes
-
Black-market labs with no safety protocols
Refinement stabilizes chaos energy into usable forms:
-
Fine powder
-
Liquid slurry
-
Compressed fuel cells
But refinement is never perfect.
Every batch carries:
-
Residual instability
-
Trace chaos signatures
-
Unpredictable side effects
The best Grind is expensive.
The worst Grind is still used.
🚗 3. Grind as Fuel: Motion Is Power
The most visible use of Grind is as fuel.
Under the Dome, mobility is survival—and power belongs to those who can move.
Grind powers:
-
Scavenger rigs
-
Armored transports
-
Gang war machines
-
Courier bikes
-
Baron-controlled caravans
These engines are:
-
Loud
-
Temperamental
-
Dangerous when pushed too far
Overloading a Grind engine can:
-
Dramatically increase speed
-
Destabilize nearby magic
-
Trigger catastrophic explosions
DM Tip: Treat vehicles as risk-reward systems, not just transportation.
🧪 4. Alchemy: Bottled Chaos
Grind is central to Dome alchemy.
It can:
-
Amplify potions
-
Replace rare magical components
-
Stabilize volatile compounds
-
Act as a powerful catalyst
Common uses include:
-
Stimulants that push the body beyond exhaustion
-
Temporary mutation suppressants
-
Chaos-reactive explosives
-
Perception-enhancing tonics
But every use introduces exposure.
And exposure accumulates.
🔮 5. Spellcasting: Power at a Cost
Some spellcasters incorporate Grind directly into their magic.
This allows them to:
-
Extend spell duration
-
Increase area of effect
-
Punch through magical interference
-
Cast when they otherwise couldn’t
But this power comes at a cost.
Using Grind in spellcasting risks:
-
Magical feedback
-
Mutation triggers
-
Detection by authorities monitoring unauthorized use
Magic fueled by Grind isn’t refined.
It’s forced.
🤖 6. Grind as a Drug
Grind is not just fuel.
It is also a substance people depend on.
For constructs and artificial beings, it can function as:
-
A power enhancer
-
A sensory amplifier
-
A temporary override of built-in limitations
Effects may include:
-
Increased reaction speed
-
Heightened awareness
-
Simulated emotional states
-
Loss of control
For organic beings, Grind is harsher:
-
Euphoric bursts followed by crashes
-
Hallucinations tied to storm memory
-
Long-term physical degradation
Addiction is common.
And extremely profitable.
💰 7. Grind as Currency
In many districts, Grind is more valuable than coin.
It is:
-
Divisible
-
Universally useful
-
Always in demand
People trade Grind for:
-
Food
-
Protection
-
Information
-
Identities
-
Favors
Debt is often measured in Grind—and interest compounds quickly.
Because unlike money, Grind is never abstract.
It is always useful.
⚖️ 8. Control, Scarcity, and Power
Grind defines the power structure of the Dome.
Those who control:
-
Harvesting routes
-
Refinement facilities
-
Distribution networks
Control everything else.
This leads to:
-
Baron monopolies
-
Guild wars over supply chains
-
Black markets undercutting official systems
-
Artificial shortages to drive demand
Grind is rarely truly scarce.
It is made scarce.
🧠 9. The Hidden Truth of Grind
Officially, Grind is a miracle resource.
Unofficially, there are whispers:
-
That refined Grind still “remembers” the storm
-
That overuse attracts chaos attention
-
That certain batches behave differently… intentionally
-
That Grind is not just fuel—but a bridge
A bridge between:
What the Dome allows
And what it is trying to keep out

Optional Mechanics Ideas
-
Grind Burn: Gain advantage on a roll at the cost of later exhaustion or mutation risk
-
Overload Engines: Boost vehicle speed with a chance of catastrophic failure
-
Chaos Exposure Track: Repeated use leads to escalating side effects
For Players
Ask yourself:
-
What is your relationship with Grind?
-
Do you rely on it, profit from it, or avoid it?
-
What happens when you run out?
🕯️ Closing Thought
Under the Dome, people tell themselves Grind is just a resource.
A tool. A fuel. A means to survive.
But everything about it says otherwise.
It comes from chaos.
It carries chaos.
And the more it’s used, the more the Dome depends on it.
Which raises a question no one in power wants to answer:
What happens when survival itself is built on something that was never meant to be controlled?
Thanks for reading. Until Next Time, Stay Nerdy!!
