Well the whole damn thing worked out. Here is how. Go with the crazy. And be willing to convert on the fly without much agonizing whether you got it right or not. Conversion you say? Yes, while I used the adventure material to run the session, we are also playing my game Deluxe USR Sword & Sorcery DUSRSS), which is much different than the traditional d20, 6 attributes and a class type game systems. But you need to be good at this if you ae going to use any outside adventure material from other games. Which will be everything if you are playing DUSRSS.
The Howl is another great example of quality adventure content available for peanuts from independent creators these days. As a Crypt Keeper, I know I do not need another version of the rule book. I need nightmare fuel to feed the campaign beast. Adding outside material is an essential part of my job at the table. The trouble is where do you find great stuff in a landscape of AI trash and poorly thought out ideas which made it to print? If you are playing Old-school DnD I recommend Bryce Lynche's adventure review blog Ten Foot Pole. He has you covered with curated lists of some really dope stuff.
Howl gives the right amount of intriguing detail and evocative writing so the DM can convey the feel of the place quickly and adroitly. There are factions in the village which further define the environment, opening up multiple avenues of play. This is one of the features of the good stuff available these days. Creators understand the importance of factions being played out in a living game world. In fact, factions make a campaign setting so much more then geography and scale. And you can run the adventure adequately at the table with the book in hand. But not recommended.
Read the entire adventure before you decide how to use it, how it will fit into the game world if called. The nuance and hooks written inside the adventure will allow you to find the adventure's rightful place in your pantcampaign. But you are going to want to meditate and let the pieces jell. I didn't give myself that opportunity. I used the adventure with only preliminary reading of the content. This situation and site location offer many possibilites in any fantasy setting.
So I read hard and fast and we ended up with a nice nagical trip into the shadow world for a game session which would have been otherwise cancelled. What emerged was an adventure I used on the fly and found it easy enough to parse so I could make it "fit" into the current game and enough cool stuff going on (think factions) that even if the plot of the module was not the plot of my players I could use the adventure premise as a whole and shave where needed. I found the adventure intriguing. If you are looking for PCs to come across a town with problems, this adventure is a good pick.
