Then I need to figure out wtf Faeins are doing in Druidia -- might contradict both R and O's sections otherwise. Apparently George's ancestor is a Spriggan *and* named after a Druid. Interesting.
Control the distance to Druidia more closely. Ryden mentions it without the name in 10-R -- he is an ygg or so away maybe, so if so just say "from his home'. Also change one of the references to fifty-two -- that's another key number. It should be fifty-two from Rainshade, because that's where Cipactli and Deema/Diyani are, and Rosamund during book #2 as well.
I should imply somewhere in the Ferritinium section that there are similar mines for silicon for glass. Keep it subtle, though -- I feel like it'll be a plot point in book #2. Or maybe sand shipments from Druidia. The segment when T talks to W is perfect for this here. Especially since it's close to the first mentions of glass. Also the leshian Grove uses mirrors -- conveniently also related to Winifred.
