What happens when two delve crews compete for a starship captain's favor while facing cosmic horror in the ventilation ducts? Join our playtest crew for lessons in layered scenario design.

Journey through slipstream space with veteran roleplaying gamers as they playtest "The Library of Apan'ra," a Coriolis: The Great Dark scenario built using Ask Agger's methodology. Host Eli Tremors and Peter Randel's longtime friends Tim Rasmussen, Mikael Andersen, and Høgni Kallehauge explore how the journey to Auriga created multi-layered tension through biological horror, political rivalry, and cosmic mystery.

WHAT YOU'LL LEARN:

• Create layered obstacles that operate at multiple scales simultaneously
• Integrate cosmic horror with practical problem-solving for maximum impact
• Use rival NPCs to generate ongoing tension without forced combat
• Design journeys that functionally prepare players for main events
• Balance crisis moments with routine for natural pacing rhythm

THE PLAYTEST EXPERIENCE:

Discover what happened when the crew volunteered for ventilation duct clearance while competing with a suspicious "geological survey team" for the captain's favor. Experience claustrophobic horror as they crawl through passages filled with crystalline arthropods and bioluminescent colonial structures that violate conventional biology.

Høgni's laboratory analysis reveals organisms with crystalline matrices integrated into living cells—impossible by standard science. The crew faces a dilemma: share findings with rivals or maintain information advantage? Small decisions during the journey create lasting factional consequences.

EPISODE HIGHLIGHTS:

Minutes 1-6: Meet the rival crew and learn how professional courtesy masks strategic competitionMinutes 6-17: Into the ventilation ducts—cosmic horror meets practical engineeringMinutes 17-21: Intelligence gathering and the cost of information sharingMinutes 21-25: Scenario design principles—why these techniques work

Translating Cosmic Dread: Fidelity vs. Function in Coriolis's "The Quarantine Station" Nightmare

Going over some of my old roleplaying materials I found the classic Mansions of Madness collection for Call of Cthulhu, and of the scenarios - the Sanatorium is a favorite of mine, and I thought how if this was transformed into a Coriolis the Great Dark scenario.

So with the aid of Claude, I tried to work with the idea, and I think it could work.

This Debate is a discussion about this. So is the previous episode, which used the Deep Dive format to discuss the same material.

Part 3 of 3 (segment 4): From Concept to Publication

How do you transform sophisticated scenario design into a usable document that game masters can actually run at the table?

In this concluding episode, hosts Peter Randel, Carsten Eriksen, Christian Eriksen, and Elisabeth Tremors explore the often-overlooked art of scenario publication. Building on the structural foundations and action design from previous episodes, we examine how visual design, information architecture, and thoughtful handout creation determine whether The Library of Apan'ra succeeds in practice.

• Information ecology: designing for multiple reading modes (prep, play, deep study)
• Typography and layout as functional infrastructure, not decoration
• Creating essential delve maps: surface overview and depth cross-section
• Handout philosophy that enhances immersion without creating barriers
• Campaign integration frameworks that support both episodic and ongoing play
• Editorial techniques that make complex content accessible without dumbing it down
• The publication as teaching tool: showing methodology, not just content

Whether you're publishing scenarios for others, creating materials for your own table, or studying how design choices affect usability, this episode provides sophisticated frameworks grounded in practical application.

Scenario designers preparing for publication • Game masters creating custom adventures • Anyone interested in information design and usability • Fans developing Coriolis campaigns • Designers studying how layout supports play • Writers transforming ideas into usable documents
