A fantastic little module. Very old-school in setup and presentation. It's got some mini-sandbox elements to it that could be blown up to cover 3 or four full game sessions.
ACTUAL PLAY EXPERIENCE: If you're willing to truncate the setup a little bit to get to the action, you can turn a lot of the "meet the people in the village" setup into startup box-text. A lot of people like that sort of slow-build intro role-playing (I'm one of them), but for the session where I ran this I knew I only had a single session. Fortunately, the setup is easy to truncate, and doing that makes it possible for you to do the presented dungeon crawl (repairing a geomantic ward in a ruined volcano monastery before it fails and brings on the destruction of the village full of nice natives) in four to five hours.
I ran it for a DCCRPG game, so I had to do a little stat conversion work, but that's not tough. There are three unique new monsters in there, but the quasi-AD&D stat lines are simple enough that swapping stats is easy. The encounters (random and keyed) are a blast, and the monastery itself is a tightly-written masterwork of dungeon design.
For free!? You don't even need to think twice. Download this puppy right the heck now.
