I have Shil's notes for the campaign and it certainly had it's moments. The bit about Grabthar scoring the criticals and utterly vaporizing the main bad guy in the final battle was from the kingmaker campaign. I've just never been able to get myself motivated enough to write anything up. I was planning on starting with a parody of Arnold's Conan's movie beginning "And one day he would sit upon a throne won by his own hand, but that is a story for another time.... No! Wait, this is that story".
I still have the spreadsheet I was using to track our investments in the Kingdom, if that becomes useful. Not sure how much of those mechanics was Shil's or the adventure path. I suspect the later, so it might be helpful
