Under the Dome: A Simple Delivery (Post apocalyptic D&D adventure)

Weird D&D Monster Lore Deep Dive: Illithids or Mind Flayers

An Adventure About What Happens After the Hard Part

The job is done.

The party went beyond the Dome.
They survived the storms.
They extracted the Grind.

They made it back.

That was the hard part.

What’s left should be simple:

Deliver the Grind. Get paid. Move on.

Under the Dome, nothing that involves Grind is ever that simple.


🚪 The Setup: A Clean Exchange

The party has a buyer.

Maybe it’s:

  • A Refiners Guild contact
  • A Grind Baron intermediary
  • A trusted fixer
  • A dealer like Vexa or a smuggler like Sable

The terms are clear:

  • Meet at a controlled location
  • Deliver the Grind
  • Receive payment

No negotiations.
No surprises.

That’s the promise.

And under the Dome, promises are always conditional.


🧾 The Delivery Site

Choose a location that feels stable—but watched:

  • A warehouse near a transit hub
  • A refinery intake station
  • A secured loading dock
  • A quiet backroom in a “legitimate” business

Everything appears routine:

  • Guards are present but relaxed
  • Paperwork is prepared
  • Payment is visible—or confirmed

This should feel like the moment players exhale.

Let them believe it’s over.


⚠️ The First Problem: Something Is Off

Before anything goes wrong, something feels wrong.

Pick one or more:

  • The buyer is late—and that’s unusual
  • The guards are different than expected
  • The paperwork references a shipment the party didn’t make
  • The Grind container reacts subtly (heat, vibration, faint sound)
  • Someone nearby is watching too closely

Nothing explodes yet.

But the situation is no longer clean.


💥 The Complication: The Grind Isn’t Just Grind

When the deal begins, introduce the twist.

The shipment is not what it’s supposed to be.

Possible complications:

1. Contaminated Batch

The Grind reacts unpredictably.

  • Crystals shift or “breathe”
  • Nearby magic distorts
  • Someone handling it experiences a surge or hallucination

The buyer may refuse delivery—or try to lower the price.


2. Marked Shipment

The Grind has been tagged.

  • Tracking sigils
  • Invisible markers
  • Ledger-linked identifiers

The party didn’t just bring back Grind.

They brought back attention.


3. Missing Weight

The shipment doesn’t match expected volume.

  • Someone skimmed it
  • The crystals degraded
  • The storm changed them

Now the party is short—and someone thinks it’s intentional.


4. It’s Alive (Subtly)

The Grind reacts like something aware.

  • It pulses in response to voices
  • It reacts to specific individuals
  • It resists being separated

No one wants to be the first to say it out loud.


🕶️ The Interruption: Other Interests Arrive

Before the situation resolves, someone else shows up.

Choose a faction or NPC tied to your previous posts:

  • A Syndicate crew claiming the shipment is theirs
  • A Baron’s enforcers freezing the deal
  • A Refiners Guild inspector declaring the batch unsafe
  • A Stormbound agent trying to destroy it
  • The Pale Auditor, observing—and rewriting the rules

They don’t necessarily attack.

They complicate.

Now the party isn’t just delivering Grind.

They’re standing at the center of competing claims.


⚖️ The Pressure: Make a Decision

The situation escalates quickly.

No matter what happens, the party must choose:

  • Complete the deal as planned
  • Walk away and keep the Grind
  • Sell to a different buyer
  • Destroy the shipment
  • Protect it from everyone else

Each option has consequences.

There is no neutral outcome.


🌩️ Escalation Options

If you want to increase tension, introduce one of these:

Grind Surge

The shipment destabilizes.

  • Magic fluctuates
  • Equipment fails
  • Nearby people react unpredictably

Containment Lockdown

The location seals.

  • No one leaves
  • Authorities take control
  • Everyone becomes a suspect

Violence Breaks Out

Not necessarily started by the party.

  • A faction makes a move
  • Someone panics
  • A single mistake triggers chaos

💰 Resolution: Payment Has a Cost

No matter how it ends, the party is changed.

Possible outcomes:

  • They get paid—but flagged in the system
  • They lose the shipment—but gain new allies
  • They keep the Grind—and gain enemies
  • They expose something—and destabilize a faction
  • They survive—but are now being watched

The job is technically complete.

But under the Dome, completion is rarely the same as success.


🧠 Themes to Lean Into

  • The illusion of “safe” work
  • Control vs unpredictability
  • Ownership of dangerous resources
  • Trust as a temporary condition
  • The cost of surviving success

🎲 Using This Adventure in Your Campaignunder the dome

This works best when:

  • The party has already risked themselves outside the Dome
  • Grind is established as valuable and dangerous
  • Factions are active and competing

It serves as:

  • A transition from exploration to intrigue
  • A way to introduce factions directly
  • A reminder that the Dome is just as dangerous as the outside

🕯️ Closing Thought

The party survived the storms.

They crossed the wasteland.
They extracted chaos from a broken world.

They came back alive.

And now they have to do the simplest part of the job:

Hand it over.

Under the Dome, that’s where things get complicated.

Because the moment Grind changes hands, it stops being a resource.

It becomes a question:

Who gets to control what was never meant to be controlled?

Thanks for reading. Until Next Time, Stay Nerdy!!
