After the potentially world-shattering Wrath of the Righteous, the new adventure path has moved to something somewhat calmer and less immediately devastating. Indeed, the first instalment of Mummy’s Mask, The Half-Dead City by Jim Groves, has one of the calmest openings for any adventure path. This isn’t a bad thing. It provides a contrast with other adventure paths and sets the tone for this one. While big things may well happen down the line, this adventure path is taking the time to set the scene and build things up before letting all hell break loose.
The Half-Dead City is very much a dungeon crawl, and while I’m not the biggest fan of pure dungeon crawls, this is a well-made one and one I can imagine myself running at some point. As a consequence of delving into tombs, there’s not a lot of opportunity for interaction with NPCs, but nonetheless, it does manage to have several extremely well-developed and interesting NPCs. The PCs may not get a lot of time with these characters, but that time will almost certainly be memorable (assuming the GM plays them well).
