I am running a fantasy campaign (using the Ptolus setting), and the PC just looted a "conspiracy board" from the hideout of a rather unhinged creature.

I've added a bunch of elements that might or might not be relevant for the campaign. And the element with the most strings to other elements was "beer price increases".

And I'd like to mess with the minds of the players some more. Thus, I could use some ideas for sinister reasons why the beer prices in a city might have increased.

Any suggestions?
