Hi, I've played a number of DH and DW roleplay scenarios and I decided to try my hand at GMing one as well.
Try as I might to prepare solutions to foreseeable problems, every now and then I find my players leading themselves down a route that I haven't prepared. Trying to steer them away from it by leading clues to routes I have prepared and all but one time I have gotten them to lead themselves back on the scenario I have prepared.
Last session however they didn't pick up on these clues and continued going down a route I wasn't prepared for so I basically tried stonewalling them with some seriously equipped guards they would not have been able to beat. However this this caused a problem in itself, as they were trying to gather evidence of a crime, they were not dealing with a criminal organisation so they started waving "we are inquisition you will help us". Now because it had gone so far from my playbook I had no idea what to do as official imperium organisations can't exactly say no to the inquisition. Any tips on how to avoid this situation in the future? Or to deal with it when it pops up?
