I’m not a very visual person, and it’s very difficult for me to imagine concrete details, especially logistical details, when writing. It’s even harder to keep them consistent when I do imagine them. So early on in the writing of the Firmament series, I decided to draw a scale diagram of the Surveyor bridge to help myself keep it straight throughout the series. Very simple–I just made it on Microsoft Paint–but it served its purpose!
