Quarist,
Since the robbery of the gear and item is a non-event...(meaning it is going to happen no matter what). It is the recovery of the items that is the fun thing. The locations of everything is random, as the bandits scattered after the robbery, and have divided the loot.
As for the "evil cult". That is the story your lord gives you. As to the cult accually being evil, or even a cult, when I get the scenario done and released, you will have to play it and figure things out in the allotted time
