Minor spoilers follow.
Enjoyable exploration of a tower with a moon worshipping/werewolf theme; undead are the main opponents. More than just a treasure hunt, as there is a captive to rescue, rival adventurers, and various items with which one can interact. Consistent tone: the seemingly bizarre spectral dance makes sense after later revelations; imaginative magic items which fit the backstory. Treasure might be a touch light, but there are interesting items for which you will need to find the right buyers. Some rousing combats to win.
One aspect that could be improved is the presentation of immediately important information in room keys: possibly bullet points or short boxed text could be used. The adventure does address attempting to enter via upper windows. Maps are clear, and the repeats of individual levels in the text are helpful.
In play, the party scared off the rival group, gained useful information from the Wise Wolf, and triumphed after some tough battles; they recruited Mariya.
Familiar themes, but stylishly done, well crafted. Highly recommended.
