I modified this scenario and ran it for my players.
They went off piste and circumvented a chunk of the plot, not that I expected them to actually follow anything as planned.
I think one of the main differences is that while House Neleus does want to be peacekeepers and find a mutually acceptable solutions, House Sindri approached it from the view of what they can get out the situation while keeping a lid on things.
A fun session, thanks for providing it.
