Bought this and ran it with my party, wove it into the campaign so a lot of details needed to be tweaked but the material is pretty light on details so it was extremely easy to fit into the campaign. However, there are a lot of grammatical and spelling errors throughout the text. The Showdown section specifically references what I assume were draft names for the Elder Being's abilities but when I first read through the adventure I had only skimmed the stat blocks so did provide a slight amount of confusion when I started prepping the adventure. In all, it was a very fun adventure to run, but I think some of the motivations for characters, specifically in the Hidden Temple, are too sparse or non-sensical, really does require the DM to rework a few details because I wasn't completely satisfied with Part Two straight out of the box. I would really like this to get another editing pass and an updated version with some of the grammatical fixes. I also found it a little surprising that there was an included Black Lake map but nothing for the final encounter.
