Building Worlds in the Forge
How the Forge Agent turns a description into a playable world, what the building blocks are, and how you stay in control.
Updated July 2, 2026
The World Forge is where you build your own playable world. Describe what you want in plain language and the Forge Agent drafts proposals; you approve, edit, or remove each one. Nothing becomes part of your world until you approve it.
Working with the Forge Agent
- Start with your genre. Genre shapes how the AI narrates, the currency, the starting location, and the look of the game. Pick a built-in genre or describe your own and the Agent helps you craft it.
- Be specific. "Three rival smuggler crews fighting over a drowned harbor city" gives the Agent far more to work with than "make some factions." Concrete names, tensions, and stakes lead to richer proposals.
- Iterate in the chat. The Agent remembers the conversation. Reply with "make it darker" or "give them a hidden motive" and it builds on what came before.
- Control the scope. Ask for a whole world in one pass, a few specific pieces, or one block at a time, whatever fits how you like to build.
The building blocks
A world is made of typed blocks. The Agent proposes them for you, and you can also add or edit any of them by hand:
- Core info: your world's name, genre, tone, and one-line hook.
- World Bible: the durable truths the AI must always treat as fact.
- AI Guidance: narration style, pacing, consequences, and things to avoid.
- Player Setup: the character-creation steps players go through to start.
- Template Blocks: reusable details the opening scene can slot in.
- Codex: your world's wiki of lore, locations, factions, characters, creatures, items, and secrets. DM-only secrets go in hidden notes that players never see.
- Premise: an open starting hook the AI builds a fresh opening from.
- Archetype: optional character templates players can pick at the start.
- Item: custom gear and equipment for your world.
- Rule: a world rule you want the AI to enforce.
Reviewing and approving
Every proposal lands in a pending list. Approve it, edit it before approving, or remove it. The Agent never writes to your world on its own, so the canon is always something you chose.
Playtest, then publish
Playtest your world from the Forge to feel how it opens, then publish when it is ready. Publishing runs an automated safety review and lists your world in the Community for others to play. The details are in publishing your world.
