The limelights were added at Moshe’s suggestion. In the original drafts of the book, I had bonfires burning outside. That was problematic, however, since they not only required a lot of fuel, but getting them close enough to the windows to provide enough light meant getting them close enough to be dangerous to the glass because of the heat. In addition, Moshe pointed out that bonfires just wouldn’t be intensely focused enough in their brightness to provide the right illumination for the stained glass windows. (And, of course, I HAD to illuminate the windows. Why go to all the trouble of putting the balls in gothic cathedrals if nobody could see the windows?)
So, anyway, Moshe came up with the limelights as a fix. They actually work quite well—they fit the general level of technology I place the Final Empire as having, and the provide focused and intense light. As I understand it, they were the way that stages were illuminated to show the actors during the nineteen hundreds. Hence, being in the limelight as a phrase for someone who is being paid attention to.
