This is exactly what I've wanted since I started running Curse of the Crimson Throne last year.
Unfortunately, as this is coming out in November, I'll likely be wrapping up this campaign by then and these pawns will no longer be of much use to me (My prep work is nearly finished for all of A History of Ashes and I'll start prepping for Skeletons of Scarwall in the next month just to stay ahead of the game).
Still, this is such a great thing for people who have yet to run this campaign or are thinking about running it once again. Kudos to you guys for releasing this. I hope that you guys will follow suit and release pawns for some of the other older adventure paths.
Oh, and nice, printable, to-scale encounter maps for us old schoolers who still like to play face-to-face would be fantastic. :-)
