Your ideas · Your rules
Turn your own concept into reusable rules, adapt a Library seed, and keep ownership and versions clear.

Describe the result in plain language before looking for a Library entry: “I want to stitch memories into maps,” for example. Discuss what that means with the DM. Break it into subjects you can affect, actions you can perform and any special rules it needs. You can author a primitive, effect, capability, heritage or item in the Atelier. The community Library provides inspiration; your concept does not have to match an existing entry.
02
In the Atelier, choose the kind of piece you are building and give it a clear name and description. A primitive grants one reusable permission or rule. Describe its intended scope, limits and price; add a mechanical rule when a tracked number or behavior should change. The description explains what happens in the fiction. A mechanical rule helps the sheet calculate it. Neither replaces the table’s judgment about an actual action.
03
An effect groups related primitives; a capability compiles pieces into a ready idea for play. Select the relevant pieces, describe targeting and resolution, and state duration, upkeep and consequences where needed. Preview the composition to check that it says what you mean. Saved capabilities are shortcuts: owned primitives can still be combined into new actions at the table.
04
Fork makes your own copy of a Library piece or public character. Open its preview or sheet, choose Fork, then work on your copy. A public character opens read-only; fork it to change Vitality, consequences or its build. Your edits to the copy do not rewrite the original author’s work. Review inherited rules and costs before using the copy.
05
Open your own creation in the Atelier or open edit mode on a character you own or have edit permission for. Change the description or composition, inspect the preview and budget, then save. Reading a Library preview does not give edit permission. Fork a piece owned by somebody else when you want your own version. A character can keep a pinned older version; review an offered update before adopting it.
06
Keep a draft private while shaping it. Use the available sharing or publishing controls when you want others to read or reuse it. Publishing is a separate choice from writing a useful rule for your own table. Check the current visibility before you finish.
07
Agree its price and permissions with the DM, then acquire the primitive using available BU. You can invent and purchase a piece during a session, including combat when it makes sense for the scene. Buying it grants access; the particular action still needs an agreed resolution and cost. Keep a note of the ruling so the next use is easier.
