Setting Primer
This is Starfinder 2e with a few setting twists. If you know SF2e, you're 90% there.
The Premise
Five hundred years ago, humanity fled a dying galaxy through an ancient alien gate. Three hundred years ago, something broke reality and merged countless alternate timelines into one. Twelve years ago, the peace that held everything together started unraveling.
You're a crew—smugglers, salvagers, investigators—navigating a galaxy where the past bleeds through, institutions are failing, and the people you trust matter more than the systems that don't.
Tone: Firefly meets Andor. Working-class heroes. Found family as survival strategy. Hope earned, not given.
What's Different from Standard SF2e
Most of Starfinder 2e works exactly as written. Here's what's unique to the Forge:
The Sundering
Three centuries ago, an event called the Sundering merged countless alternate timelines into one reality. This explains:
- Why ruins exist from civilizations that never happened — Collapsed-timeline remnants dot the galaxy
- Why some people remember things that didn't occur — Timeline echoes occasionally bleed through (rare)
- Why the dead aren't always staying dead — The Corpse Fleet fields soldiers from timelines that lost
For most characters, this is background flavor. You might have occasional déjà vu or strange dreams. Dissonance (timeline bleed) is purely narrative—it's not a mechanical system you need to track or worry about. Use it for character flavor if it interests you; ignore it if it doesn't.
The Way
The Way is the Force, the weave of magic, the current that makes FTL travel possible. It manifests through seven elements: Light, Metal, Life, Water, Shadow, Air, and Fire.
Way-sensitives are rare—maybe one in ten thousand. Most people have never met a trained practitioner, though they've heard stories. Major stations might have one or two; frontier settlements count themselves lucky to have any. Those who can touch the Way can form covenants with an element—gaining power in exchange for following that element's principles.
Fire is scarred. The ancient being who embodied it fell to fear and corruption. Fire practitioners bear visible marks (ember eyes, ash-gray hair) and face social suspicion. They're not evil—but Fire remembers what fear made it do.
The Drift
FTL travel works through the Drift, a dimension alongside normal space. The Forge (a star at the galaxy's center) burns as a constant light that Navigators orient by.
Ships that lose sight of the Forge's light get lost—or worse.
Where You Are
The Forge is both the galaxy's name and a specific place—a Precursor facility hidden inside a star, inaccessible since the Sundering. Its reflection in the Drift is what Navigators steer by.
Elysium is the political and economic heart of the galaxy. The city of Aurelia rises around the Ark Spire—one of the original colony ships, now eight kilometers tall. The Concord governs from here. The Way Academies train here. If you need something official, this is where you go.
The Pact Worlds are the systems that signed the Elysium Compact after the Sundering—"civilized space" where Concord law applies (more or less). The Outer Fringe rejected the Compact; out there, authority is whoever has the guns.
The Hollow Edge is where the Forge's light fades. Ships that go too deep don't come back. Something's out there. No one knows what.
What You Need to Know About Classes
Almost all SF2e classes work without changes. Three have Forge-specific flavor:
| Class | What's Different |
|---|---|
| Mystic | Elemental Connections replace standard connections. Choosing an element means entering a covenant—you gain power, but must follow that element's tenets. See reference/player-options. |
| Witchwarper | Purely thematic retheme, no mechanical changes. Witchwarper powers are explained as controlled timeline bleed—you reach into collapsed timelines and pull possibilities into the present. |
| Solarian | Thematic connections to Athena, the ancient being of Light who sacrificed herself to stabilize reality. Optional flavor—you can ignore it if you prefer. |
Other classes (Envoy, Operative, Soldier, etc.) work exactly as written.
