There's a LOT of great flavor in this adventure. I found it a little too loose, though and struggled running it the first time. It was unclear to me why the PCs would spend any time in the Driftwood Orchard or Outer Precincts. You're supposed to roll a random encounter for every hour they spend there, but it just ended up being one random encounter and then move on.  The Polis is described as towering above the rest of the city. The players never even considered stopping to search one of the other districts.

The second lesson I learned - I wish there had been some guidance about how and when the PCs might interact with the NPCs. Mine never met the Oracle or Peotr (except as the Childe), and would not have met the Corpse Master except I thought to include a showdown with him in the Ziggurat. 

But all my complaining aside, there's SO much good, flavorful content here. I've run it twice and am going to run it a third time, but I wish it had been better structured to make my first run as good as my third.
