You yell at the translator, gesticulating at the foreign Prince just like he does at you, to make him shut up, or you will make him by throwing him into the dankest of dungeon cells.
Your body language, tone of voice, and the translator's words make the Prince of Perunians shut up. He even looks impressed-of-sorts.
He sits down on the cold stone floor of the throne room, and his men follow suit.
Then the conversation can progress - the Perunians actually want to establish a land route through the mountains to avoid the price-gouging of western merchants, whilst also hoping to contain the Fomorian threat and begin exploring their south and southeast (your northeast). The Prince is proposing a system of caravans, where hardened men and soldiers would travel alongsied Perunian merchants to exchange goods and patrol the mountains along the way.
"What can they offer to us?" The translator chats with the Prince some more, before turning to you.
"Ivory of mighty giant cows, antlers of the white stags, brown and black furs of forest animals, and items of copper and rock." The courtiers murmur, clearly interested in valuables and exotic items. "The people of Perun would love to obtain weapon-worthy metal, for theirs is hard to work and scarce to obtain, and they've heard that southern lands are aplenty in iron."
A) "We will buy their crafts and furs, but we won't sell any iron."
B) "Pah! A proposal not worthy of Rug! They should return home before they test my patience more."
C) "We can sell them some iron, but we have no need for skins and work of their craftsmen."
D) "That sounds good! Let us establish the trade caravans to enrich and form closer ties between our nations."
E) "The trade proposal is unworthy, but establishing a route between Perun and Rug sounds good to me. Through fires of beast-slaying we shall prosper!"
