You guys did a fantastic job of getting this together; the PDFs look great. I have to imagine RHoD will play much better as a 4e adventure in general (thanks largely to the minion rules), so I really appreciate the work you did to get it here.
That said, somehow in the 20 seconds I spent looking at the Monsters PDF, I caught a stat block error. Azarr Kul has 284 HP; his bloodied threshold should be 142, not 147.
Again, great work, and thanks for putting this together.
