Name and Add World Building Features
If I didn't come up with a name for any of the worldbuilding elements I added, I do that at this point and fill in the questionnaires as much as I can. I don't force myself to come up with details at this point. I add things as I write, so I still have some flexibility where these things occur. Once I've filled in the information I am able, I use the "find and replace" feature again for the fillers.
I also draw new maps for places that I came up with while writing the outline.
