To craft a compelling campaign for Thirteen Parsecs: Beyond the Solar Frontier, you need to lean into the "Hard-ish Sci-Fi" aesthetic: grimy cockpits, looming corporate shadows, and the terrifying silence of the void.
In this setting, space isn't just a backdrop—it’s an antagonist. Here is a campaign framework titled "The Icarus Debt."
Campaign Concept: The Icarus Debt
The crew starts not as heroes, but as indentured salvage contractors for the Acheron Holdings corporation. You own a ship, but you don't own it. Between fuel costs, air filtration taxes, and interest, you are one bad haul away from being spaced.
The Hook
While scavenging a "dead" sector 11 parsecs out, the crew recovers a black-box data core from a vanished exploration vessel, the S.S. Venturer. The data suggests that the "Frontier" isn't empty—it’s being intentionally vacated by something much older than humanity.
1. The Core Conflict: Pressure from All Sides
A good Thirteen Parsecs campaign should balance three specific types of tension:
Environmental: The ship is breaking down. Every jump requires a "jury-rig" roll.
Political: Three rival factions (The Sol Hegemony, The Belt Syndicates, and Acheron Holdings) all want the Venturer’s data.
Existential: Something in the deep black is "listening" to faster-than-light comms.
2. Key Locations
| Location | Description | The "Vibe" |
| Station 13 | A hollowed-out asteroid serving as the last refueling stop. | Blade Runner meets a submarine. |
| The Ghost Nebula | A graveyard of pre-war ships and high radiation. | Claustrophobic and eerie. |
| New Eden | A corporate-owned "paradise" planet where the air is filtered and the debt is eternal. | Sterile, high-tech, and oppressive. |
3. Campaign Progression (The Three Acts)
Act I: The Scavengers
The crew takes "bottom-feeder" jobs to pay off their weekly ship debt.
Act II: The Signal
The black box is decrypted. It contains coordinates to a "Parsec 14"—a jump point that shouldn't exist.
Act III: The Threshold
The crew arrives at the coordinates. They find a massive, non-human megastructure—a "Gate"—that is currently waking up.
4. Mechanic Spotlight: The "Oxygen vs. Credits" Die
In this campaign, introduce a Resource Die. Every time the crew spends credits or takes a long journey, they roll a $d10$. On a 1 or 2, the die shrinks (to a $d8$, then $d6$). If it hits zero, the ship suffers a critical life-support failure. This forces the players to choose between safety and profit.
GM Tip: Never make the ship feel safe. Describe the hum of the engines changing pitch, the smell of ozone in the vents, and the way the stars look just a little too distant.
To make your ship feel like a lived-in pressure cooker, you need NPCs who bring their own baggage. These characters are designed with "competing interests"—they help the players run the ship, but they also have reasons to compromise the mission.
To kick off The Icarus Debt, you need a mission that feels like a "paycheck" but quickly turns into a "survival horror" scenario. This mission introduces the crew to the mechanics of salvage, radiation management, and the creeping dread of the Frontier.
Mission Title: The Iron Husk
Objective: Board the derelict freighter Caldwell’s Folly, retrieve its high-grade Deuterium fuel rods, and extract before its decaying orbit pulls it into a gas giant’s gravity well.
The Setup
The Client: A middle-manager from Acheron Holdings named Vance. He offers to shave 10,000 Credits off the ship’s debt if you bring back the rods.
The Hook: Vance "forgets" to mention that the Caldwell’s Folly was carrying a classified biological cargo.
1. The Approach (Skill Challenge)
The Caldwell’s Folly is tumbling. To dock, the pilot must succeed on a Complex Maneuver Roll.
Success: Smooth docking at the main airlock.
Failure: The ships collide. The Icarus takes Hull Damage, and the crew must enter through a jagged breach in the "Lower Engineering" deck (the most dangerous part of the ship).
Environmental Hazard: The Cold Void
Since the ship is powered down, the temperature is dropping. Every 10 minutes of real-time play, have the players roll a $d20$. On a 1-5, their suits' heaters flicker, causing 1 point of Fatigue.
2. The Interior: Three Key Zones
The ship is a maze of floating debris and frozen droplets of... something dark.
| Zone | Description | The Threat |
| The Bridge | Flickering holos and the frozen remains of the Captain. | A security turret is still active but "blind"—it fires at any sound over a whisper. |
| Medical Bay | Smashed glass and "Growth" on the walls. | This is where the Secret Data Core is hidden, guarded by the Venturer's first casualty. |
| Engineering | The Fuel Rods are here, glowing a soft, deadly blue. | The deck is magnetized. Heavy gear (like Jax’s shotgun) sticks to the walls. |
3. The Encounter: "The Drifter"
While the crew is pulling the fuel rods, Mags picks up a frantic signal on the internal comms. It’s not a person—it’s the ship’s AI, screaming in binary.
The Enemy: A "Drifter." This is a crew member who was exposed to the Venturer’s data signal. They aren't a zombie; they are "phase-shifted." They move sporadically, appearing to teleport 2–3 feet at a time (like a lagging video feed).
The Twist: The Drifter isn't trying to eat them; it’s trying to "plug" them into the ship’s computer to "show them the Truth."
4. The Climax: The Death Throes
As soon as the last fuel rod is pulled, the Caldwell’s Folly groans. The gravity well of the gas giant has caught it.
The Clock: You have 4 Rounds to reach the Icarus.
The Complication: The docking clamps are frozen shut. Silas needs to use a plasma torch to cut the ship free while Jax holds off the phase-shifting Drifters emerging from the vents.
The Reward & The Price
The Credits: If successful, the debt is reduced.
The "Loot": In the Med-Bay, they find a Strange Vial labeled Project Icarus. If Dr. Thorne sees it, he will try to hide it from the rest of the crew.
The Fallout: The Icarus’s sensors now show a permanent "Ghost Signal" following the ship at a distance of exactly 13 Parsecs.
GM Tip: During the "Cold Void" rolls, play a low-frequency ambient drone in the background. If the players take too long to argue about who carries the rods, increase the volume.
The Crew of the Icarus
1. Silas "Rust" Vane (Chief Engineer)
A veteran of the Belt Wars who treats the ship's reactor like a temperamental god. He’s more comfortable talking to a plasma manifold than a human being.
The Vibe: Greasy overalls, smells like recycled ozone, constantly chewing on synthetic nicotine.
The Secret: He’s been skimming "surplus" fuel to sell on the black market to pay for his daughter’s medical treatment back on Mars.
Utility: Can fix any mechanical failure, but every "miracle" repair increases the ship’s Debt by 500 credits.
2. K-76 "Kaye" (Android Navigator)
An outdated, decommissioned labor unit that was illegally re-sleeved with navigation software. Kaye is prone to "existential glitches."
The Vibe: Calm, overly formal, but occasionally stares at the stars for hours without blinking.
The Secret: Their memory banks contain a hidden map of Acheron Holdings’ restricted black sites—they are literally "stolen property."
Utility: Grants a $+2$ bonus to navigation rolls, but if the ship is scanned by Corporate patrols, there is a 15% chance Kaye is detected.
3. Dr. Aris Thorne (Exobiologist / Medic)
A high-society defector who claims they grew tired of New Eden. In reality, Aris is a disgraced researcher who knows too much about what the black box contains.
The Vibe: Sharp, clinical, and judgmental of the crew’s hygiene.
The Secret: They are addicted to "Stim-Z," a proprietary corporate sedative. If they run out, their hands shake, making surgery dangerous.
Utility: Can heal injuries and identify alien artifacts, but requires expensive medical supplies to stay "functional."
4. "Mags" Marek (Sensors & Comms)
Young, twitchy, and incredibly talented at "listening" to the void. Mags is a "Void-sensitive"—someone who claims they can hear the Ghost Nebula.
The Vibe: Oversized headphones always on, caffeine-jittery, terrified of silence.
The Secret: The "voices" Mags hears aren't hallucinations; they are encrypted signals from the Venturer that only their specific brain-mapping can pick up.
Utility: Can detect stealth ships and anomalies others miss, but long-range scanning causes Mags to take Stress damage.
5. Jax Lowery (Security / Heavy)
A former Acheron Holdings enforcer who "retired" early. Jax is the muscle the crew needs when a salvage op turns into a firefight.
The Vibe: Scarred, carries a modified kinetic shotgun, surprisingly soft-spoken until the shooting starts.
The Secret: Jax is an undercover informant for the Belt Syndicates. Their job is to make sure the black box ends up in Syndicate hands—not the crew's.
Utility: Provides a massive advantage in combat encounters, but will occasionally "suggest" detours that benefit his secret employers.
In Thirteen Parsecs, the vastness of the frontier doesn't just wear down the ship's hull; it erodes the crew's sanity. Using a Stress & Trauma system turns the psychological toll of deep-space salvage into a tangible gameplay mechanic.
The Stress Tracker
Every character has a Stress Track (1–10).
Gain Stress: When missing a critical roll, witnessing a "Drifter," running low on Oxygen, or taking a "Debt Penalty."
The Breaking Point: When Stress hits 10, the player must roll on the Acute Breakdown Table. After a breakdown, their Stress resets to 5, but they gain a permanent Trauma Strain.
I. Acute Breakdown Table (Rolling at 10 Stress)
Roll $1d6$ when a character snaps in the heat of the moment.
| Roll | Result | Effect |
| 1 | Catatonic | The character freezes for $1d4$ rounds. They can do nothing but stare into the void. |
| 2 | Paranoid | The character believes another crew member is "compromised." They refuse help or healing for the rest of the mission. |
| 3 | Vent Rage | The character lashes out at the nearest object (or person). Deal $1d6$ damage to the ship's console or an ally. |
| 4 | Compulsive Repair | The character becomes obsessed with a minor mechanical flaw, wasting their next two turns fixing something that isn't broken. |
| 5 | The Void Call | The character begins opening an airlock or removing their helmet to "hear the star better." Must be physically restrained. |
| 6 | Cold Clarity | The character suppresses all emotion. They gain an immediate success on their next action, but gain 2 Permanent Trauma Strains. |
II. Permanent Trauma Strains
Trauma Strains are the long-term scars of the Frontier. They can only be removed by spending massive amounts of Credits on "Neural Re-mapping" at a high-end Corporate facility like New Eden.
Phantom Alarm: You constantly hear a low-oxygen alarm. $-1$ to all Sensor and Comms rolls.
Agoraphobia: You feel exposed in open spaces. You take $+2$ Stress whenever you are outside the ship (EVA).
The Shakes: Your hands won't stay still. $+1$ Difficulty to all Repair and Medical rolls.
Corporate Zealot: You become obsessed with the Debt. You refuse to participate in any mission that doesn't have a guaranteed Credit payout.
Void-Touched: You start finishing other people's sentences. It’s creepy. You have a $-2$ to all Social/Persuasion rolls with "normal" humans.
III. Reducing Stress: "The Shore Leave"
Between missions, players can reduce Stress, but it always comes at a cost.
"The Grime & The Glory" Choice:
Cheap Synthetic Alcohol: Reduce 3 Stress. Cost: 50 Credits. Risk: Roll $1d6$; on a 1, wake up with a "Hangover" penalty for the first half of the next mission.
Neural-Dampers: Reduce 6 Stress. Cost: 500 Credits. Risk: No physical side effects, but it adds to the Acheron Holdings Debt.
Meaningful Connection: Talk it out with a crew member. Both players reduce 2 Stress. Risk: You must share a "True Secret" about your character's past.
Managing the Crew's NPCs
Remember, your NPCs (Silas, Kaye, etc.) have Stress tracks too. If Silas hits 10 Stress, he might sabotage the engines so the ship has to stay docked at a station where he feels safe. If Mags snaps, they might broadcast the ship's location to the "voices" in the nebula.
NPC Interaction Table
Use this table when the crew spends a "Long Jump" together to see how tensions flare.
| Roll (d6) | Interaction |
| 1 | Kaye glitches and accidentally vents 10% of the oxygen. Silas is furious. |
| 2 | Dr. Thorne is caught stealing meds from the emergency locker. |
| 3 | Mags swears they heard the players' names in the static of a dead star. |
| 4 | Jax and Silas get into a physical fight over "stolen" rations. |
| 5 | Kaye shares a piece of forbidden corporate data with a player they trust. |
| 6 | A "Quiet Moment": Two NPCs bond over a shared hobby, lowering the ship's Stress level.
