Starts ok, and chapter 3 is a true highlight. But chapters 4 and 5 were a letdown and the adventure really needed another editorial pass. several instances of the adventure mentioning rolling a check to gain information and then just never calling out what they learn.
Maybe I missed something but when did the corpse fleet regain the asteroid? The party grabbed it in chapter 1, took it to the dwarf fleet, then at the end its supposedly on the corpse fleet planet... when did this happen?
I recommend that GMs just steal the cool chapter 3 and ignore this adventure. Also, this adventure is very short and shouldn't count as an Adventure Path, its only 4 chapters/levels
