sounds great, but there's going to be ~some~ scripting to make it happen.
It sounds like it'll be more of a party quest than a solo, but we can make it work for both. It just depends.
Anyways, how about we make the conversation port the pcs (i can handle that, no problem) to the area that they're going to do what they want to do in.
For the roadblock: a road with a couple of barricades and some ditches set up, along with some defensible positions... the line of npcs walks up, someone comes up to talk to the pcs, who will attempt to intimidate the people into giving up their goods peacefully. One or two guards resist anyways, but by and large everything happens quietly.
For the sneaky approach: we'll make a lil canyon where the npcs have set up camp at night, the pcs can sneak in and loot things, but if they get caught all hell breaks loose.
It doesn't just have to be a badly quest, either. Slavery growing now that Iuz has occupied the Bandit Kingdoms (Or combination of free lords, whatever you want to call it) and it could be efforts to free captured slaves.
Anyways, great quest idea padre! it's for sure going to be implemented, but as it's your idea let me know what you think about methods.
