The differences were minor. Early on I had shown Matt and whoever was helping him with layout my pencil sketch map, but I didn't want that used in the published magazine. I had commissioned a much better map from Andreas Claren. I had also commissioned Ian Baggley to Illustrate the adventure. For some reason, the polished map and the illustrations didn't make it into the magazine. I wasn't happy so I decided to publish the adventure. Once I did that, I made some light changes and a few small additions. I'm a little hazy on the specifics though, because it was 2009.
