Bring forth what is within you.

A story asking for language.
A book asking for form.

A world only you can build.

A life changed in the making.

What you imagine can become real enough for another human being to enter.

Where the spark becomes the work.

An idea arrives like lightning. The house still needs framing.

Story Imaginarium is a creative house built for the framing. We make tools, stories and teachings for everything that comes after the lightning.

Most writers learn that part by accident over a decade, one abandoned draft at a time. We'd rather hand it over now, while your book is still alive.

Wonder does not excuse weak story architecture. Architecture does not require the death of wonder.

We do both.

You can feel your book. First Forge helps you build it.

Bring the spark, the notes, the half-built world, or the story you have carried for years.

First Forge is our novel-development system, and it uses AI in one chair only: the editor's. It is trained to read your material closely enough to find the book already alive inside it, and to say plainly what is missing.

FIRST FORGE HAS LAUNCHED

The tool can be powerful. The work has to be yours.

We use AI. Not like that.

There's a correct chair for it, and it isn't the author's. It's the editor's. An editor's whole job is to help a writer get the thing across: clear, alive, worth a stranger's evening. That's real work.
 

So we created Sovereign with AI: Keeping the Human Flame Alive in the Age of Synthetic Intelligence — a training series about using these tools without surrendering your voice, judgement, imagination or authorship.

START WITH THE CREATIVE SOVEREIGNTY CODEX

Stories, essays, craft & other things we find in the dark.

Story Imaginarium is also a publication: writing about imagination, story, craft, sovereignty, world-making, and the stranger country they live in.

Some pieces teach craft. Some tell stories. Some follow an idea until it opens somewhere unexpected and luminous.

Dispatches from the work of making things dangerously real.

Moon Does Not Write Her Book

A twelve-year-old with a four-day writing system, a dog who will not stay by the door, and a river about to do something she will spend the rest of her life failing to describe.

About the creator

She belongs to the part of the world that hasn't been written down.

Read the founder note

Sarah Berti writes as Leaf. She has spent twenty-five years taking people into places that change them — wilderness, classrooms, and the interiors of their own unfinished books.

She holds degrees in English Literature from Trent University and Outdoor & Experiential Education from Queen's University. At Trent she studied myth under Sean Kane, author of Wisdom of the Mythtellers. She has taught in public and private schools, in wilderness programs and in transformational training settings — Norval Outdoor School, Outward Bound, director of Mulmur Hills Camp, co-director of Camp Prospect — designing curriculum and experience for a quarter of a century. The work has always been the same: build the correct conditions, then let experience do what instruction cannot.

Her attention sits where nature, myth, coherence and neurodivergence meet. It is a strange country to specialize in, and it explains most of what she makes.

Her poetry appears in Reliquiae, Mythic Circle, RIC Journal and Luna Arcana. Her novel Embersong, co-written with O'ran Ruadh, was published in 2022, with film rights held by Mirthquake Productions.

As a developmental editor she has spent years inside other people's manuscripts, finding the story underneath the draft and building the structure strong enough to carry it. She has spent considerably longer inside her own. That work — the close read, the question the writer has been avoiding — is the foundation under First Forge. Her editorial practice is Bright Leaf Literary, offering editing and ghostwriting for people with something difficult to get out.

She lives off-grid at Heartwood, in the Land Between — the rugged country where the Canadian Shield gives way to the St Lawrence Lowlands — on a rocky shore surrounded by thousands of acres of protected wildland. She grows food, harvests wild edibles, and keeps company with ravens, herons, moss, billion-year-old rock and a very old turtle. She has never been able to stop paying attention.
