Mixing the "Raygun Gothic" surrealism of C.L. Moore’s North West of Earth with the grimy, claustrophobic body horror of The Red Room and The New Flesh creates a campaign setting that is essentially "Cyberpunk at the Edge of Cosmic Madness."
In this world, the frontier of space isn't a high-tech utopia; it’s a decaying, visceral nightmare where the laws of physics are as fragile as the human ego.The Red Room's Orbital Decay has all of the advantages for this genre. This blog post picks right up from here
The Setting: "The Eroding Frontier"
The campaign takes place in the Belt of Sighs, a region of space where reality is "thin." Here, the sleek, brass-and-glass aesthetics of Northwest Smith’s solar system are being eaten away by the systemic rot and biological mutations of The New Flesh.
The Aesthetic: Imagine Art Deco starships with interiors lined with rusted, pulsing veins.
The Conflict: Outlaws and smugglers (Smith-types) are trying to survive while their own bodies and ships are being "reclaimed" by a sentient, necro-biological virus known as the Orbital Decay.
Integration of Core Elements
1. The Protagonists (The Outlaws)
Players take on roles similar to Northwest Smith: cynical, rugged explorers with itchy trigger fingers. However, instead of just dodging Venusian blasters, they are managing their Corruption/Mutation tracks from The New Flesh.
The Struggle: Every time you use "pre-collapse" tech or travel through the "Thin Places" (Moore's influence), you risk an Orbital Decay event where your gear—or your arm—starts growing teeth.
2. The Antagonists (The Thirsting Gods)
C.L. Moore’s ancient, soul-drinking entities (like Shambleau) are reimagined as the ultimate "Engineers" of The Red Room.
Shambleau 2.0: Not just a psychic vampire, but a biological interface that connects victims to a massive, orbital meat-server.
The Red Room: A physical location in the deep vacuum—a space station built of bone and flickering monitors where the "Old Ones" broadcast signals that force the evolution of the New Flesh.
Campaign Mechanics: The Decay Cycle
To blend these systems, use a Dual-Resource Loop:
| Feature | Influence | Mechanic |
| Heat/Notoriety | North West of Earth | How badly the planetary authorities want your head. |
| Systemic Decay | Orbital Decay | The physical breakdown of your ship's life support and hull. |
| Bio-Transgression | The New Flesh | The "Gifts" you gain as your humanity erodes. |
Starting Adventure: "The Scarlet Rust"
The Hook: The players are hired by a veiled woman (reminiscent of Moore’s Jirel of Joiry or a Red Room handler) to retrieve a "Memory Core" from a derelict luxury liner drifting near the gravity well of Jupiter.
The Twist: The liner isn't empty. It has undergone Orbital Decay. The ship’s AI has merged with the passengers' biomass to create a singular, screaming consciousness.
The Environment: Hallways that look like brass corridors but feel like throats.
The Goal: Extract the core before the players' own cybernetics begin to reject their flesh and join the ship.
"The gun felt cold in Smith’s hand, but the hand itself felt... wrong. It wasn't just the sweat of the Martian heat; it was the way his skin seemed to ripple toward the trigger, hungry for the spark of the discharge."
Tonal Palette
Vibe: Gritty, pulpy, and nihilistic.
Color Palette: Oxidized copper, bruised purple, and fluorescent surgical white.
Music/Sound: Analog synthesizers layered over the sound of wet, tearing fabric.
This D100 table blends the pulp-horror surrealism of C.L. Moore (where entities change your soul) with the industrial-body horror of The New Flesh and The Red Room (where the change is physical, wet, and agonizing).
In this setting, mutations aren't just "buffs"—they are the Orbital Decay claiming your sovereignty.
The New Flesh: Mutation Table (D100)
| D100 | Mutation Name | Clinical & Visceral Effect |
| 01-05 | Leaden Marrow | Your bones thicken and turn to a heavy, grey metallic composite. Increase Armor/DR, but your movement is sluggish and loud. |
| 06-10 | Ocular Bloom | Clusters of tiny, lidless eyes erupt along your collarbone. You cannot be surprised, but you suffer constant psychic "noise." |
| 11-15 | The Gilled Throat | Slits open in your neck, lined with vibrating silver filaments. You can breathe toxic atmospheres and vacuum for 1d10 minutes. |
| 16-20 | Vocal Lathe | Your vocal cords become serrated. You can mimic any sound or frequency, but your natural speech sounds like grinding metal. |
| 21-25 | Porous Dermis | Your skin becomes a fine mesh. You can "sweat" a paralytic neurotoxin, but you take double damage from chemical or fire attacks. |
| 26-30 | Recursive Digits | Fingers grow smaller fingers at the joints. +2 to fine motor skills (picking locks, surgery), but holding a heavy weapon is painful. |
| 31-35 | Nervous Webbing | Your nervous system partially exits your body as fine, glowing "hairs." You sense electricity and heat signatures through walls. |
| 36-40 | The Second Maw | A vertical slit opens in your abdomen. It functions as a digestive tract for "raw biomass"—it can consume evidence or enemies. |
| 41-45 | Chitinous Plates | Patches of your skin harden into iridescent, insect-like shells that hum when near high-voltage machinery. |
| 46-50 | Hydraulic Veins | Your blood is replaced by a pressurized black ichor. Strength increases significantly, but a single puncture causes "explosive" bleeding. |
| 51-60 | Translucent Flesh | Your skin becomes clear as glass. Your internal organs are visible and have begun to rearrange themselves into non-human patterns. |
| 61-70 | Synaptic Antennae | Two twitching, fleshy stalks grow from your temples. You can "hear" the thoughts of those dying nearby. |
| 71-80 | Biological Interface | Your palm develops a USB-like organic port. You can "jack in" to machines, but the machine's "spirit" can damage your sanity. |
| 81-90 | Exoskeletal Rig | Your spine grows outward, forming a cage of bone around your torso. You are incredibly durable, but can no longer wear standard armor. |
| 91-95 | Crystalline Scabs | Wounds heal over with jagged, sharp crystals. You are a walking hazard to touch, but your body is slowly turning into a mineral. |
| 96-99 | The Living Tool | One arm fuses with your primary weapon. You never drop it, but you are now a literal "living weapon." |
| 00 | Apotheosis | You become a "Red Room" Conduit. Your body collapses into a slurry of sentient meat and data. Roll a new character. |
Managing the "Decay"
In a campaign mixing these systems, mutations should be treated as a trade-off.
The Benefit: Every mutation provides a specialized survival edge in the harsh North West frontier.
The Cost: Each roll on this table should reduce the character's Humanity or Sanity score. As the body becomes more "functional" for the void, the soul (as Moore would describe it) becomes a stranger to the self.
GM Tip: When a player rolls a mutation, describe the scent (ozone and copper) and the sound (wet clicking) to emphasize the New Flesh aesthetic over traditional fantasy mutation.
To track the erosion of the self in the face of the New Flesh, we use a dual-track system: The Ego (Sanity) and The Resonance (The Decay).
In the style of C.L. Moore, madness isn't just "seeing a monster"—it is the horrifying realization that your own soul is becoming unmoored from your body. In the style of The Red Room, it is the physical "glitch" of the human hardware.
The "Alienation & Decay" Mechanic
1. The Ego Track (0–20)
Every character starts with an Ego Score of 20. This represents your "Northwest Smith" core: your memories, your human desires, and your sense of self.
Mutation Cost: Every time you roll on the Mutation Table, permanently reduce your Max Ego by $1d4 + 1$.
The Thresholds:
15-19 (Distanced): You struggle with empathy. You find human faces "flat" and uninteresting.
10-14 (Uncanny): Your movements are jerky/mechanical. Animals snarl at you. You take a -2 penalty to all social interactions with "pure" humans.
5-9 (The New Flesh): You refer to yourself in the third person or as "We." You no longer feel physical pain, only "data input."
0 (Total Decay): Your consciousness uploads to the Red Room or merges with the ship. You are an NPC.
2. The "Mirror-Shock" Check
Whenever a player uses a biological mutation in a stressful situation, or witnesses a crewmate undergo a visible "wet" transformation, they must roll a Mirror-Shock Check.
The Roll: Roll $1d20$.
If the result is HIGHER than your current Ego: You lose $1$ point of current Ego as you catch your reflection and don't recognize the thing looking back.
The "Moore" Effect: If you fail by more than 5, you suffer a Sensory Hallucination (e.g., the stars begin to scream, or you smell the scent of a long-dead Venusian lover in a sterile airlock).
Alienation Complications
When your Ego drops below certain milestones, the crew (and the world) reacts. Use this table for narrative consequences:
| Ego Level | Trait | Gameplay Consequence |
| 15 | The Cold Eye | You cannot "Bond" or heal the stress of others. You are an island. |
| 12 | Static Speech | When you speak, those nearby hear a faint radio hum or the sound of wet clicking. |
| 8 | Biological Dysmorphia | You must spend 1 hour a day "pruning" or "calibrating" your mutations, or take a penalty to all rolls. |
| 4 | The Hunger | You no longer eat food; you require raw biomass or direct electrical grounding to "recharge." |
The "Safety Valve": Grounding
Because this is an RPG campaign, players need a way to fight back against the decay—though it should always be temporary.
The Memento: If a player interacts with a "Human Object" (an old photograph, a physical book, a non-digital musical instrument), they can regain $1d4$ temporary Ego.
The Vice: Northwest Smith had his "Space-Juice" and his blaster. Engaging in a purely human vice (gambling, brawling, or Moore-esque romance) stalls the decay for one session.
"He looked at his hand—the fingers too long, the skin the color of a bruised plum—and for a moment, he couldn't remember the name of the girl he'd left behind in the Martian ruins. He only remembered the way the radiation tasted."
This encounter, titled "The Charnel Processor," is designed to be the climax of a mission. It forces a direct confrontation between the pulpy heroism of North West of Earth and the systemic, biological horror of The Red Room.
Encounter: The Charnel Processor
The players have reached the core of a drifting vessel (or an ancient Martian tomb). The air is thick with the smell of scorched copper and wet ozone. In the center of the room sits a Red Room Terminal: a monolith of obsidian glass and twitching, exposed optic nerves.
The ship’s reactor is hitting critical mass. The "Orbital Decay" has progressed so far that the manual overrides have melted into a single, pulsating mass of meat.
The Problem: The Lock-Out
The terminal requires a High-Density Bio-Authentication. The system doesn't want a password; it wants a consciousness to balance the cooling equations.
The Three Choices (The "Sacrifice" Mechanics)
The players must choose one of the following methods to stabilize the ship. Each has a different cost to their Ego and New Flesh tracks.
Option A: The "Smith" Gamble (Neural Override)
The player attempts to "shoot" the logic board with a high-frequency blast or a frantic, manual hack.
The Roll: Hard Tech/Logic Check.
The Success: The ship stabilizes, but the feedback loop is brutal.
The Cost: Lose 1d6 Ego. The player develops "Static Vision"—for the next 24 hours, they see everyone as a wireframe skeleton.
Option B: The "New Flesh" Communion (Biological Interface)
A player with at least one mutation "plugs" their mutated limb into the terminal. The machine recognizes the Orbital Decay and grants access.
The Roll: Automatic Success.
The Cost: Permanent Mutation Roll. The limb used to interface becomes a permanent part of the ship's architecture for 1d4 minutes. When they pull away, they lose 1d10 Ego.
The Result: The ship is saved, but the player's arm is now a translucent, multi-jointed "data-limb" that twitches in time with the ship's engine.
Option C: The "Moore" Sacrifice (Soul-Bleed)
The player offers their memories as "buffer data" to soothe the screaming AI.
The Roll: Wisdom/Willpower Check.
The Success: The ship’s alarms go silent. The lights turn a soft, comforting amber.
The Cost: Lose 1d12 Ego. The player forgets one significant NPC or background detail from their character sheet. To the rest of the crew, that person still exists. To the player, they are a total stranger.
The "Red Room" Complication: The Feed
During the interface, the terminal begins broadcasting. Every monitor in the room flickers to life, showing "The New Flesh" in its final form—a galaxy-sized organism of metal and bone.
GM Description: "The glass doesn't show your reflection. It shows a version of you that hasn't happened yet—a beautiful, terrifying lattice of silver veins and ivory armor. The machine isn't trying to kill you; it’s trying to invite you home."
Aftermath & Rewards
If they survive, they gain "The Mark of the Room."
The Reward: They can now "speak" to any derelict ship they encounter, gaining a +4 to navigation.
The Curse: They are now "Leaking." Occasionally, their footsteps leave behind a trail of black, oily data-ichor that attracts hungry entities from the North West void.
