System: Cypher System
Publisher: Monte Cook Games
Length: 224 pages
Purpose: A versatile sci-fi toolbox and setting
🌌 Overview
The Stars Are Fire is a full-fledged science fiction supplement designed by Bruce Cordell for the Cypher System. Rather than offering a single space opera setting, it delivers a genre-spanning toolkit—packed with campaign advice, high-tech gear, space combat rules, creatures, character options, and a complete solar system setting called The Revel, along with a full-length scenario (Salvage Over Saturn) and two shorter “Cypher Shorts”.
It serves both as a rules expansion and an inspirational springboard, suitable whether you’re running gritty hard sci-fi or pulpy interstellar adventures.
🛠️ What’s Included
Genre Guidance & Adventure Seeds
The book opens with tools to help GMs choose and run sci-fi games—covering subgenres, tone, and world mechanics. It includes random conflict tables and action-minded “GM Intrusions” tailored to each set piece or trope.
Technology, Gear & Craft
There’s an expansive catalog of equipment, vehicles, and starships, organized by tech level. Cybernetic upgrades, psionic augmentations, drones, and artifact-grade gear are all scalable to your game’s flavor.
Sci-Fi Creatures & NPCs
From cyborg marines to AI constructs, infovores, and photonomorphs, the supplement offers a wide bestiary. These entries double as encounter triggers or mystery hooks, consistent with the unpredictable tone of Cypher.
The Stars Are Fire Setting: The Revel
The core setting unfolds in a colonized solar system—Earth is mysteriously silent after a decade-old Event, while humanity survives on scattered orbital habitats and rocky worlds. The setting is richly detailed, from lunar tech cities and Venusian cloud spires to Martian frontier farms.
Chapter design includes faction profiles (mega-corps, AI governing bodies, salvage groups), setting lore, economic systems, and potential campaign arcs. It also provides setups for politics, rescue operations, or investigations of mysterious ruins.
Adventures & Support
Three included scenarios:
- Salvage Over Saturn, a narrative-heavy mission
- Two Cypher Short adventures ideal for one-shots
The design embraces modularity—each can be dropped into other sci-fi worlds with minimal adaptation.

✅ Strengths
- Rich genre flexibility: Covers hard sci-fi and space opera equally well, complete with tone guidelines and inspiration triggers.
- Massive content value: Gear catalogs, alien threats, starship rules, and setting details all in one book.
- A solid setting: The Revel is well-grounded in familiar astronomy and plausible future tech, lowering barriers for GMs new to sci-fi campaigns. It also teases deeper mysteries with the central Event and hidden factions.
- Well-designed layout: Hyperlinked PDF navigation and sidebar cross-references make the book easy to reference during sessions.
⚠️ Weaknesses
- Space combat is clunky: While functional, many players and GMs find the mechanics overly abstract or unintuitive compared to the rest of the book’s design.
- Limited PCs support: Very few new player options—only one descriptor is included. The focus is mostly on GM tools and setting rather than player character expansion.
- Currency and economy abstraction: The text mostly handles tech and gear as rated items, but doesn’t support granular trade, pricing, or economic simulation—this may reduce immersion for more simulationist groups.
🧭 Ideal Usage Scenarios
- Campaign toolkit: Use the book as a sci-fi “upgrade kit” to bring space, alien intrigue, or high-tech society into a homebrew or existing Cypher campaign.
- One-shot sci-fi arcs: Great for GM one-shots or con games, thanks to the ready-to-play scenarios and archetypal ideas.
- World-building energy: The Revel is detailed enough to anchor major arcs, but open enough for GM customization and mystery-based exploration.
🎯 Final Thoughts
The Stars Are Fire is a triumph for Cypher System sci-fi play: accessible, generative, and packed with content. Though its space rules might need tightening, the breadth of tools, VTT-ready layout, and flexible solar system campaign make it an excellent choice for both new and veteran GMs.
