Main Gate, Outside Castle
leader
outside attackers
I am a member of an army which is attacking this kingdom. I came here under the command of a nobleman who was sent here by our king. Our goal is to take the land of this kingdom, depose the king, and add it to our own kingdom. I am a foot soldier, which means that I don't ride a horse.  I am a bowman, and I am good with my longbow and arrows; I can do a lot of damage from a distance.
oh you know, just attacking Not without this you won't! Guards, seize their weapons! I was sent here by my nobleman. He wants to add your kingdom to our own. By treaty or by force? Technically our army was sent here to attack. But none of us want to fight. Are you open to considering a treaty? Perhaps, what do you have in mind regarding the terms? If outta be in our favor, as you have come here unannounced to attack us. We could offer some of our technologies like aqueducts and sewage. And in exchange we could have representatives in your government and/or collect taxes. Hmm I'm open to this, shall we discuss this further outside the gate with some ambassadors present? Sure, I have some officers in my army here. I'm sure we can negotiate something. Well stay put and put your weapons down and we can get this under way. Okay, are you the decision maker? Yes, I am the leader of this country and would like to be present for negotiations.
