As someone who played Expedition when it came out, long long ago, I was excited to find Wizards was coming out with a follow up (and one that was entirely for charity, to boot).
This adventure is presented with 8ish hooks that can be used in combination with most WOTC hardcovers from Tomb of Annihilation onward. There should be no problem dropping this adventure into most campaigns and it even has guidelines on how long to run it (as a 4 hour one shot, as a few sessions of "short play" or as a huge adventure).
The artwork is all of different styles, but that's a minor hiccup when compared to the pure dearth of content available here. Looking forward to finishing this adventure up!
