After the standard account of the state of the setting (chiefly for those new to Odysseys and Overlords) we get the background to the adventure: a merchant called Madeina Ilrekar hired an adventurer, a fellow called Jorasco Vinn, to go into the Untamed Gauntlet to prospect for precious metals. Apparently he didn't do very well, when he returned he spoke of an ancient shrine, the name of which is lost to antiquity. Now Madeina's daughter has vanished, and she thinks that Vinn has kidnapped her with an eye to reviving the practice of human sacrifice at the shrine he discovered!
This is where the party comes in. Perhaps they have heard about the daughter's disappearance, or maybe Madeina hires them to go in search of her... she is, it transpires, of marriageable age, and Madeina has a few potential suitors in mind. There's an optional opening encounter with Madeina, or you can start the adventure with the party already travelling through the Untamed Gauntlet. One encounter is provided for the journey, you may wish to add others of your own devising.
The main part of the adventure is the exploration of the shrine. This starts with a puzzle to unravel to get in which is very well presented. You get the puzzle itself (and its solution - not all GMs are puzzle fanatics, after all!) and suggestions about how to use die rolls to help the party crack the code and gain admission, if they don't figure it out on their own. The few rooms are described clearly, along with contents and inhabitants, and the party ought to find out what happened to the daughter. Every possible outcome is covered, depending on what they decide to do about the situation.
Overall, it's a neat little adventure. Can the party save the daughter? Only you and your group can tell!
