A prompt forge for tabletop roleplaying

Conjure the unseen.
Picture every scene your party imagines.

Chimera-Forge turns your campaign's personas, locations, and atmospheres into precise, evocative prompts for any image generator. Build a private library — then compose portraits, vistas, and encounters in seconds.

For the Game Master

Worldbuild without the wait.

The drowned chapel. The kobold quartermaster. The festival at dusk. Add them as Locations and Personas — Chimera-Forge remembers every detail when you forge a prompt.

Locations NPCs Atmospheres Encounters

For the Player

Your character, fully realised.

Define your persona once — looks, gear, category, notes. Then generate portraits across moments: first session, level-ups, the backstory, the aftermath.

The Workflow

A library, not a blank page.

Most prompt tools start from scratch every time. Chimera-Forge is built around the things you already track at the table — and lets you snap them together the moment the story calls for an image.

I. Step

Build your library.

Add Personas (characters and objects) and Locations (with type, epoch, and atmospheres). Tag everything. Your library persists across sessions and grows with your campaign.

II. Step

Write your scene.

Create a scene by writing a narrative description. Reference library items inline — use #p:slug for Personas and #l:slug for Locations. Attach a Base Prompt Style to steer the visual direction.

At the altar of #l:drowned-chapel, a figure waits — #p:vael-pale-blade shrouded in silence and ember light.

III. Step

Generate the prompt.

Chimera-Forge's AI reads your scene, resolves every inline reference, and applies the chosen style. The result is an optimised image prompt — saved as a Prediction you can rate or set as your scene preview.

Ink wash, high contrast. A moonlit coastal ruin, shattered bell tower draped in fog. A pale figure in dark armour stands at a flooded altar, ember light catching the blade.

Your Library

Every campaign has a memory. Yours, finally, is searchable.

Four building blocks. Infinite compositions. Build your Personas and Locations as you prep — Chimera-Forge remembers Vael's pale eyes and the chapel's shattered bell tower the same way.

Forged at real tables.

A selection of pieces our early fellowships have summoned — each one tracing back to a Persona, a Location, and a set of Atmospheres.

"I described the chapel for three sessions. They never saw it. Then I added it to Chimera-Forge — and the whole table went quiet."
