I like that you were able to include such an extensive loot table. For a setting that is regional like this, it goes a long way to adding a sense of specificity to the location. I also found the idea your encounter table interesting. Things like clams being run across (I assume these are actually oysters due to the pearls) rather than just monsters/npcs was nice. If I had one critique, it was for the merfolk. The key element to the story is people getting turned into them, but in the meat of the adventure, it seems to indicate they are unaware of ever having been human. Are they a separate group of merfolk serving the Naga or people whose memories have been lost to the transformation? Perhaps I missed it as I have been reading quickly to get all of the reviews in on time.
