From publisher blurb:
The characters are hired to steal a mysterious artifact known as "The Engine" from a wealthy noble. The only catch is that they only have a single chance, with the backdrop of a high society party, showcasing the mysterious collection containing the artifact. The characters must be careful in their dealings amidst a number of nobles, well-off merchants, and other members of the social elite in attendance.
Chapel Perilous is a location-based stealth adventure for player characters of levels 5 to 7, although characters of any level may find the situation challenging.
