I ran this adventure for my latest campaign, adapting it to fit my East Asian setting but otherwise leaving it largely intact.

My players loved the mystery aspect of things, and it was certainly a change from kobolds and the like to instead have them fighting flocks of murderous birds. While I did change the final bossfight to a bit more of a fey-themed dungeon, the plot and the layout of the book made it exceedingly easy to run. A really well done module!
