Re: Canon characters killed in lit-verse. (spoilers)
It's not as big of a conspiracy as that. Apparently the editors decided they didn't like some of the stuff in IfM, and they've decided to ignore the book. Yeah, it's crappy, but as far as I know it was a one time thing. No one has said anything about any other books getting this treatment.
They say a little knowledge is a dangerous thing, but it is not one half so bad as a lot of ignorance. - Terry Pratchett, Equal Rites
