Most current designs assume the King in Yellow seeps into institutions and art scenes that already exist; what changes if you instead treat each campaign as charting the birth of a new institution (clinic, theater, archive, troupe) that is being founded under Carcosan influence from day one, and how would that origin-focus alter scenario goals, player roles, and safety concerns when the investigators are effectively designing—through their choices—the future engine of contagion for the whole city?

Answer

Treat the campaign as: “we are founding the future vector.”

  1. Scenario goals shift
  • From: uncover and contain an external infection.
  • To: decide what this new institution becomes and how dangerous it is.
  • Concrete goals:
    • Define the founding mandate (what it claims to do for the city).
    • Choose how much Yellow Sign / Carcosa influence is baked into rules, space, and culture.
    • Decide which communities it will protect vs exploit.
  1. Player roles shift
  • PCs are not just investigators; they are also founders, staff, patrons, or embedded auditors.
  • Typical roles:
    • The visionary (art director, chief clinician, lead archivist) tempted by Carcosan “insight.”
    • The fixer (administrator, lawyer, producer) who turns weird ideas into policy and budgets.
    • The skeptic/whistleblower trying to keep a mundane core.
    • The medium/canary whose dreams and breakdowns foreshadow where the institution is heading.
  • Each case becomes: “what precedent do we set?” rather than “how do we plug this leak?”
  1. Origin-focused scenario structure
  • Early arc: charters and blueprints
    • Sessions about permits, donors, space-hunting, first hires, first season/program.
    • Yellow Sign appears in drafts, contracts, floorplans, casting notes.
    • Key choice: which Carcosan elements you let stand because they’re ‘useful’ or ‘on brand.’
  • Middle arc: first clients / audiences / collections
    • Each investigation is a first: first patient, first show, first acquisition, first public scandal.
    • Outcomes harden into SOP: “how we handle missing time,” “how we stage identity shifts,” etc.
    • Carcosa seeps into intake forms, stage directions, cataloging schemas.
  • Late arc: the institution as engine
    • The clinic/theater/archive now generates cases on its own.
    • You investigate your own procedures, alumni, and buildings.
    • Endgame question: do you dismantle, reform, or surrender it to the Yellow King?
  1. How this changes contagion and clue design
  • Contagion vector = policy and culture
    • Every ruling, precedent, or design choice becomes an infectious meme.
    • The Yellow Sign works as:
      • A logo or seal.
      • A diagnostic code or shelving mark.
      • A casting shorthand or membership rank.
  • Clues are about future impact
    • Instead of “what happened last night?”: “what happens if this rule is normal?”
    • Show near-future flashes: a test group, a preview audience, a pilot ward.
    • Use dossiers, reviews, or inspection reports from 6–12 months ahead as foreshadowing artifacts.
  1. Pacing ambiguity and revelation
  • Keep Carcosa as implication in the design before overt phenomena.
  • Early sessions: ambiguous taste and branding (“why this mask as logo?”).
  • Mid: borderline supernatural, plausibly artistic or psychological.
  • Late: clear breaks in causality tied to institutional routines (e.g., everyone who reaches Tier 3 membership dreams of the same balcony in Carcosa).
  • Avoid a single “read the play → go mad” beat; instead, show how many small, reasonable founding decisions add up to something horrific.
  1. Safety concerns when PCs design the contagion engine
  • Main risks:
    • Players feeling blamed for fictional harm (“you built the bad asylum”).
    • Sensitive parallels to real institutions (psychiatry, academia, policing, art scenes).
    • Identity erosion through long-term institutional roles.
  • Tools:
    • Session 0: agree on what kinds of real-world institutions are off-limits or only loosely echoed.
    • Lines/veils on real diagnoses, real-world abuses; use fictional jargon.
    • X-card / Script Change for scenes where PCs’ decisions harm vulnerable NPCs.
    • Periodic “state of the institution” debriefs: OOC talk about where things are heading and adjust.
    • Optional “ethical load-sharing”: some dark precedents are clearly NPC-driven, so players aren’t the sole moral engine.
  1. Example campaign frames
  • Carcosan Clinic
    • PCs: founders of a cutting-edge sleep or identity clinic.
    • Investigations: unusual patients, trial treatments, research protocols.
    • Contagion: new diagnostic category based on the Yellow Sign; Carcosa-coded therapy rooms.
  • Yellow Theatre Company
    • PCs: troupe members launching a new venue and repertoire.
    • Investigations: casting disasters, missing actors, dangerous patrons.
    • Contagion: play selection, staging conventions, and a stylized Yellow Sign as brand.
  • Archive of the Un-performed
    • PCs: archivists building a city-funded collection of banned or unfinished works.
    • Investigations: provenance disputes, forgeries, visiting scholars.
    • Contagion: catalog tags, reading-room protocols, access restrictions.
  1. How this affects victory conditions
  • Win/lose isn’t just “stop the King in Yellow.” Options:
    • Contained engine: the institution is weird but mostly self-limiting; the city is scarred but not overrun.
    • Co-opted engine: city elites or cults weaponize it; PCs might gain status but lose control.
    • Subverted engine: PCs turn its machinery toward exposing or buffering Carcosa.
    • Collapse: the institution implodes; questions of who remembers and who inherits the ruins.
  1. Design guidance for Keepers
  • Track 3 simple dials on a campaign sheet:
    • Reach: how many people the institution touches.
    • Purity: how much of its core logic is Carcosan vs mundane.
    • Autonomy: PC control vs NPC/Carcosa control.
  • Each scenario should clearly move 1–2 dials based on choices.
  • Tie SAN / Stability loss not only to exposure, but to realizing what your own founding work is doing.
  1. Safety recap
  • Make “we are designing something dangerous” explicit up front.
  • Let players steer how culpable their PCs are (naive idealists vs cynical operators vs embedded saboteurs).
  • Regularly check: “Is this still fun horror, or does it feel too much like real-world institutional trauma?” and adjust scope, tone, or even reframe what the institution actually is in fiction.
