Setting as constraint: worldbuilding in two crafts

The research document for Reine’s story had a section called “Do NOT use.” Things that seemed period-accurate, checked out superficially, and would have made the story worse, because they were wrong.

That list exists in good level design too. The reference material that looks right until you find the actual spatial records, and then the flow has to change.

That moment, when research stops decorating and starts constraining, is where setting becomes a character. Both crafts have it.

What a location brief is actually for

In level design, the brief that opens a new location isn’t primarily about aesthetics. It answers: what happened here before the player arrived? Who uses this space, and for what? What does the design need the player to feel?

Those answers shape the geometry. A space built without them looks right and plays wrong. Players move through it and feel that nothing is at stake, even if they can’t say why.

Historical fiction research asks the same questions, set back a century. What was this world actually like? What were the real constraints on a person living in it? Those constraints are the design problem, not the atmosphere.

Knowing more than you show

A level designer knows the full history of a space even if players see five minutes of it. The loading bay where the heist starts had a different use before the crew arrived. The foreman’s office has a specific logic in the building. That context doesn’t appear in any player-facing text, but it shapes every sight line and every exit.

Historical fiction works the same way. The research for Reine’s route ran to dozens of verified findings. A fraction surface in the prose, as specific details or as limits on what she can plausibly attempt. The rest live in the research document, shaping what the story won’t do.

You build from more than you show. When a reader or player feels something is off, they usually can’t name it. What they’re sensing is the gap where the background knowledge should have been.

Research as reframe

The more useful research findings aren’t the ones that confirm what you planned. They’re the ones that change it.

The 1893 Paris research surfaced something about what an artist working in that time and place could and couldn’t realistically do. That finding, once known, sharpened the story’s central question. It didn’t decorate the arc. It became the arc.

Location research does this too. You go in expecting to make a stealth space and come out knowing it has to be a puzzle. The original plan was reasonable. The actual space forced something better.

When the material says no

Both crafts have a moment where research stops expanding and starts refusing. The period says no. The spatial logic says no. The records say: not that.

I’ve learned to like that moment. It’s when the work gets specific.

A constrained brief produces writing and geometry that feel like they couldn’t be anything else. Generic is what happens when you haven’t let the research in to do damage.
