This 'dungeon crawl' for 2nd-3rd level characters opens with the standard overview of the setting, useful for those who don't have any other Odysseys and Overlords material - it works with any OSR ruleset, but best with The Basic Fantasy Role-Playing Game. We then get on to the background for this adventure, being a discussion of how people turned to worship other deities when the local mob decided all-out war between themselves was a good idea. One such was called Bala, who was mildly popular with creative folk for a few years before falling out of favour again. However centuries later a rumour arose that Bala's followers had discovered the secret of eternal life, only by then nobody could remember where any temples to Bala were. The hunt was on...
... and this adventure begins with the discovery in the Untamed Gauntlet of a tablet whose inscription, according to a priest called Dendefsha (who worships another deity), contains directions to one hidden deep in the Gauntlet. He wastes no time in hiring a party of adventurers to go and take a look. Of course, other interested parties are also looking for the temple. Who'll find it first?
The adventure proper begins with the party standing on the doorstep of the temple. Actually finding it is an adventure you'll have to provide or, if wilderness adventures aren't your thing, just give the party sufficient background and start the game here. The first trick is figuring out how to get in, and it doesn't get much better thereafter: there are tricks and puzzles galore as you explore onwards. As well as rivals for the idol, which is said to be carved with Bala's secrets, there are some creatures to contend with as well.
Although small - there are only three main chambers - the temple is well-described. Details of all the traps or effects are explained clearly, with notes on relevant mechanics, saves to make, and so on, and all monsters come with a stat block to enable you to run them effectively. Player and GM versions of the map are included. The conclusion assumes that the party is successful, but does give the possibility of future allies and enemies that can be woven into further adventures.
This is a classic 'delve' adventure, with monsters to kill and loot to acquire... being short and sweet it could be a good filler or one-off adventure, or even an introduction to OSR play. It's nicely-done, however, and there are concepts here worthy of expansion should it suit your campaign to do so.
