What you can ask later

  • “Who lives in Saltmere?”
  • “Does Ilse’s backstory clash with the Reed War dates?”
  • “Which characters haven’t appeared since chapter 10?”
  • “List every item the Tide Guild owns.”

Who can see what

  • The writing team adds and edits characters and places.
  • The lead writer is the only one who can edit the Timeline, so canon dates stay put.
  • A freelance artist can read the descriptions of the characters they draw, without spoilers in the Secrets field.

How it compares with World Anvil or a wiki

World Anvil and wikis are better for rich pages with maps, images and links you browse.

Checking facts is what ADoor is good at here. Every character and place has fields your assistant can compare, and access by field keeps spoilers from people who shouldn’t see them.

How to start

  1. Open an assistant like ChatGPT, Claude, Grok or Cursor and connect ADoor through MCP.
  2. Tell it: “Keep our story world: Characters, Places, Factions, Items and Timeline, linked to each other. Invite the writers.”
  3. Keep the Timeline editable by the lead writer only.
