The hardest part of running a published setting was never the rules for me. It's the homework. Before you feel ready to run Faerûn or Eberron, there's this nagging sense you're supposed to have done the reading first: the sourcebooks, the factions, the gods. Most DMs never quite shake it. They either fall back on something they already know cold, or they throw the whole thing out and homebrew from scratch.
Edenfall started as my way around that. The entire setting assumes you've read exactly one thing: the adventure sitting in front of you.
The drop-in idea
The premise is simple enough. You should be able to pick up a single Edenfall adventure, run it cold, and never once feel like you're missing a book you were meant to read. The lore isn't a gate you clear before play. It's something you earn during it. Each adventure plants a few seeds, and the wider world grows out of them at the table instead of in a wiki somewhere.
Setting detail should be a reward for playing, not a fee you pay before you're allowed to start.
What that looks like in practice: every adventure stands on its own. The NPCs carry what they need inside the module. The locations have just enough history to feel lived-in without sending you off to cross-reference anything. The rest of the world is there, implied, but you never have to crack it open to run the night.
So what is Edenfall, actually?
It's a region on the way down. The old institutions are coming apart, newer powers are creeping into the gaps they leave, the roads aren't as safe as people remember, and the woods have gotten strange in ways nobody really wants to talk about. The party matters here, not because a prophecy said so, but because everyone else is too busy getting by to deal with any of it.
The mood is dark and pastoral. Small villages, deep forest, old ruins nobody can quite explain. There are no gleaming capitals in the core collection; the scale stays human on purpose. The trouble is local, and it usually feels personal by the time it's over.
How I actually write it
Every location, faction, and NPC in Edenfall comes down to two questions: what do they want, and what are they scared of? That's more or less the whole method. The politics, the history, the magic all hang off those two answers, which keeps the world grounded and makes it easy to wing it when the party inevitably wanders somewhere I didn't prep.
What does this person want, and what are they afraid of? Answer that and you can play almost anyone at the table without looking at your notes.
I stole this from novelists, not game designers. Characters in good fiction feel real because you can read their wants right off the page. I wanted Edenfall's cast to work the same way: not complicated, just legible enough that you always know roughly how they'd react.
Where it's headed
The Crooked Mile is the first adventure in the collection, but it isn't the first thing that happened. Plenty is going on in the region that predates the party turning up. Some of those threads run quietly through everything that follows; others I've left loose on purpose, for tables that want to pull on them.
Volume 2 is well underway. It takes the party somewhere completely different, nowhere near that road through the woods, but anyone who ran The Crooked Mile is going to recognize something in it. That part's deliberate too.
If you want to watch Edenfall come together as it grows, Patreon is where I think out loud: design notes, rough drafts, and table reports for each adventure before it ever gets its final layout.
