12. In what story did you feel you did the best job of world building? Any
side-notes on it you'd like to share?
That's a hard one to answer, because all my stories, novellas, and novels are set in the same storyworld. So I draw off details from other pieces quite a bit, and have an overall background of detail that wasn't necessarily developed for any one tale. I certainly know which story I did the most world-building for, and that was 'One Shining Day,' written for my mom. That story is set among the avarii, which meant I had to do a lot of work on the avarii culture before I wrote it--so in terms of world-building, that's the one I'm most proud of. I also did quite a bit of work for the Sutherule parts in book 5, which also show up to some extent in 'Resurrection' and 'Delarun' section 5. My biggest challenge, however, will likely be with the Shado-novella, since a good part of that is set on the Sister (the world's moon) rather than the planet the humans, hyarmi, and avarii live on.
Any side notes? For 'One Shining Day' I read the bulk of a 600-page Ornithology Textbook so I could pinpoint the avian characteristics of avarii, and work out from there how some of those influence their culture. For Sutherule, I found working through Patricia C Wrede's very exhaustive list of world-building questions quite helpful to insure I didn't overlook something.
