While the first volume provided us with a quick and fun adventure (Claws of Madness), Whispers from the Void is filled with inconsistencies, plot holes, semi-transparent NPCs and challenges that simply don't make sense the way they occur.

As I thought that the previous adventure held itself reasonably, I went blindly into this module and just found myself painted in a corner with a dull adventure as thin as hair holding together on absurdities.

It is more like a draft with some ideas put together without really checking whether they'd make sense in the end.

It was a huge amount of work to make it interesting, with more meaning and logic. I regret this purchase and it wasn't fun to DM. I almost called it a quit but for the sake of my players I re-wrote 80% of it to make it playable.

Not recommended at all, not even for the ideas or as a continuation of the prequel. It is a couple of levels below and should not have been released. A waste of time and you are better off looking for another module to continue your adventures.

Edit: 21st of March 2021 highly suspicious 5 stars reviews added. These people haven't DMed the module for real neither have picked the absurdities plaguing the plot line, not to mention missing NPCs' stats or inconsistent characters at the end. Again, at very best a draft that was never playtested. The first module (Claws of Madness) is a lot more acceptable.
