The Worldbuilder’s Grimoire · a self-paced course
Grow a living world from one small seed — in a weekend, not a decade.
Most worldbuilding guides hand you 500 questions and wish you luck. The Grimoire gives you the Imagination Engine: an 8-phase method that starts with a single compelling idea and grows it into a world where the economy, the faiths, the politics, and the conflicts all connect — because they all grew from the same root.

Sound familiar?
Every abandoned world dies
one of three deaths.
The Endless Outline
You bought the 300-question worksheet. You answered forty of them. Somewhere between “describe your world’s tax code” and “list its major exports,” the thing you were excited about stopped being fun.
The Empty Wiki
You built the vault. Folders for kingdoms, religions, timelines — two hundred pages, most of them blank. Now opening it feels like walking into a house you owe money on.
The Cold Spark
The idea arrived on fire — a city, a curse, a strange machine. You wrote two pages, hit the first question you couldn’t answer, and set it aside “for now.” That was months ago.
Here’s the part nobody tells you: none of these are discipline problems. They’re what happens when you try to build a world from the outside in — continents first, meaning later. It’s a method problem.
“A world isn’t an encyclopedia you fill in. It’s a seed you grow.”
The Grimoire’s method — the Imagination Engine — starts with one tangible, fascinating element and asks a simple question: what would this actually change? Answer it eight times, at eight depths, and you have a world where everything connects — because everything grew from the same root.
See it work
Watch one seed become a world
This is the actual example from Phase 1 of the course. One object. No map, no pantheon, no thousand-year timeline. Watch what it does.
The seed
“A smooth black stone that absorbs memories when held — and lets anyone who touches it later live those memories.”
Ask “what would this change?” — and it grows
That’s economics, crime, religion, law, scholarship, and history — pulled out of one object, in minutes, without a single worksheet about climate zones. The eight phases take that same pull and give it structure: each one deepens the seed’s consequences until you’re holding a complete, internally consistent world.
That’s one seed. Yours will grow somewhere entirely different.
The method
Eight phases. Eight things you’ll actually make.
Every phase is a handful of short lessons, a fill-in worksheet, and one challenge that ends with something real in your hands — a scene, a map, a document from your world’s past. You’re never just taking notes.
-
01
Plant your seed
Choose the one element that makes you think “I want to tell stories here” — an object, a phenomenon, a practice, a place. Define what it can and can’t do.
You’ll make: A 250-word scene of someone encountering your seed for the first time
-
02
Grow the first roots
Follow the seed into ordinary life: what it’s worth, how people use it at breakfast, what it does to a marriage.
You’ll make: “A Day in the Life” — one ordinary day, reshaped by your seed
-
03
Develop core systems
Who controls it? Who worships it? Who studies it? Power, belief, and knowledge grow up around the seed.
You’ll make: A scene between an expert and a novice — knowledge changing hands
-
04
Complexity through conflict
Surface the tensions your seed creates. The best conflicts have no villain — just people who are both right.
You’ll make: “The Dispute” — a conflict where both sides have a point
-
05
Expand your geography
Now the map — drawn because your world needs it, not because worldbuilding is “supposed to” start there.
You’ll make: The Map & Key — your first real map, with a legend that means something
-
06
Deepen the history
Write the past that explains the present. History should illuminate today’s tensions, not bury them in dates.
You’ll make: A historical document from inside your world — a treaty, a letter, a heresy
-
07
Build connected systems
Weave technology, law, and education into the web. This is where the world starts to feel inevitable.
You’ll make: The System Map — every element, and every thread between them
-
08
Bring it all together
Integrate everything into a living society with current problems and people who disagree about them.
You’ll make: Your World Bible — the complete, organized reference for every story to come

Troubleshooting guide & reading list
For the stuck days: common worldbuilding problems, diagnosed and solved, plus the books worth your shelf space.
Built for Obsidian. Works anywhere.
The Grimoire is designed around linked notes — your world becomes a living web you can see in Obsidian’s graph view. But every lesson, worksheet, and template works in Notion, Scrivener, a plain notebook — anything that can hold words.
Know thyself
Built for worldbuilders with unfinished worlds
The Grimoire is for you if…
- You’re a novelist who needs a world that won’t contradict itself in book three
- You’re a game master building a setting your players will actually want to explore — and poke holes in
- You’re a serial starter with a dozen half-built worlds and a genuine desire to finish one
- You love worldbuilding itself and want your hobby to produce something whole, not another folder of fragments
It’s not for you if…
- You want a world generated for you — this is a method you work through, not a random-table machine
- You’re after random name lists and prompt decks — the internet has plenty, free
- Your current world is already finished and coherent — go write in it, you don’t need us
We’d rather you not buy than buy the wrong thing — an unused course is just another empty wiki.
From the fireside
Worldbuilders who finally finished
“My current world has more depth and cohesion than anything I’ve created in the past decade.”
“Before the Grimoire I had dozens of abandoned world ideas. Now I have one world I’m actually using.”
“The phase-by-phase approach kept me from getting overwhelmed. I actually finished my world.”

Questions worldbuilders ask
The complete 8-phase Imagination Engine: 24 core lessons, 8 guided worksheets, and 8 phase challenges — plus 5 advanced masterclasses (magic systems, political systems, economic frameworks), the AI Collaboration Playbook, the full template collection, three worked example worlds, a troubleshooting guide, and a curated reading list. Self-paced, online, yours for life.
No. The Grimoire is built to shine inside Obsidian’s linking system — your world becomes a web you can literally see — but every lesson, worksheet, and template works with any note-taking app, or plain pen and paper.
The method works for any world that needs developing: fantasy, sci-fi, alternate history, horror, historical fiction with invented elements — any genre where the setting has to hold together under pressure.
A focused weekend gets you through the early phases with a world that already feels alive; the full engine takes as long as you want it to. There’s no schedule, no cohort, no expiry — lifetime access means the pace is entirely yours.
Yes — and it’s especially good at this. Running an existing world through the phases exposes the gaps and missed connections, and turns a pile of scattered notes into a system that actually holds together.
The Grimoire isn’t an outline — it’s a foundation. Knowing how your world works is what lets you improvise inside it without contradicting yourself. Discovery writers tend to find that liberating, not confining.

The fire’s lit
Somewhere in your notes is the seed
of your best world.
It doesn’t need another decade of planning. It needs a method. Plant it this weekend — by Monday you’ll have a world that finally holds together.
