Ooh, this one is good.
As a DM, you are going to need to be flexible however, as the options presented to the characters leaves it wide open to how they approach the situation. You could probably run this a dozen times and never have it shake out the same way twice.
Keep an eye on the clock however, and be ready to advance from Sections 3 to 4 if the action is slowed. I would recommend abbreviating the introductory section, and keeping things moving through Grimshackle jail as well. You could easily spend the whole session exploring the content in Section 3.
This adventure will allow players to feel empowered, as their tactical decisions have a real impact on how things play out. It is refreshing to see content for ALL of the factions presented.
