I have made my own PDF of the prologue that excises everything that spoils that first encounter. It ain't as pretty by a longshot as the campaign guide, I just cut and pasted the text and some graphics and used MS Word-- but it seems like an effective way to pass out the prologue to the players without giving anything away. I even scooped two nice paragraphs of non-spoilery description out of the last section and put them into the previous one, because they do a fair job of describing Gate Pass as a city.
If I did this right (I've never attached a file to a post before), the PDF should be attached. Feel free to use it.
To my mind, the stuff in the November part just foreshadows the campaign itself, and doesn't ruin anything at all. No encounters or challenges are undermined. Not to mention, by the time we get to the later modules where these characters show up, players in my group will probably have forgotten, say, Darius's inner monologue. If you're worried about any spoilers in the November section, this probably won't work for you, but otherwise, I'm putting this up as a game aid for anyone who wants their players to read the prologue without knowing what the first combat will look like.
EDIT: Morrus, this is okay, right? I figure since the Campaign Guide was a free product, you wouldn't mind packaging the prologue in a player friendly way, since there are so many free game aids people have made already, but if this isn't alright, obviously you can delete this post!
