I was relatively confident that one of those books, I think it was "The Bloody Eye" or somesuch, was done by ex-President of Paizo, Johnny Wilson.
My reason for thinking that was that that book, when it came out, found itself with both a piece of fiction in Dragon and an adventure in Dungeon, the latter of which was done by Johnny Wilson (and, IIRC, the former also, I think). It is, AFAIK, the only direct article by Wilson in either of the magazines, and none of the other Iconics books got so much support (some got a bit here and there, but not nearly that much).
