It's been a long time since I ever did any serious pontificating w/r/t disc theory, and so it was refreshing (and certainly illuminating) to see someone else describe it much better than I ever could.
If you're curious, the part I'm talking about concerns the narrator's introduction to the Kelx, p. 467-471. As I literally just finished reading these pages, I have no idea if the Kelx end up being baby-rapers or are otherwise bad people. Likewise, I'm not ready to go ahead and consider this a spoiler, either, since I have no way of knowing how relevant the Kelx are to the overall plot. As I'm only aware of one of you who've already finished the book, please feel free to leave a comment telling me if I've ruined the book for anyone.
