The Felonsine envoy is let in.
"Greetings, oh noble, gracious and most shrewd King Yoe of Methiant! My mistress and liege, Queen Karkhuta, have heard that you wish to sell some small parcels of land in your south to the Ceodwells. While she has no detail of the Ceodwellian offer, in her wisdom and generosity she offers you something even better - a dozen of the fearsome Blackheart siege engines, for your own use, along with a team of expert operators." Courtiers murmur and gasp at this wondrous offer; Fireblood powder is rare, expensive and hard to get or produce, and even more so a properly assembled team of Blackhearts, the siege engines in question producing lots of smoke, thunderous roars, not to mention they smash fortifications with ease.
"Furthermore-"
*SLAM!*"
"Now what's this!?" Yells the Ceodwellian envoy who just barged into the throne room. "How dare you, King Yoe, conduct business over the lands that you wanted to sell to my master, King Aun!"
"Why is this Ceodwellian let in? Do you have no guards, King Methiant!" The Felonsine diplomat steps aside to dodge a Ceodwell's fist.
"This is an outcry! Dishonor! Shame upon you! Those are Ceodwellian lands by promise and by ancestry! Begone, Felonsine pig!"
"As if!" The westerner shouts back. "We offer fearsome siege engines and not just few tons of cheap low quality silver from the land of poverty that is Ceodwell!"
They descend into a shouting contest. You decide to...
A) Have the guards remove the Ceodwellian so you may continue negotiating with the Felonsein envoy.
B) Shush both envoys and try to sneakily wrangle out a confession out of them - something's valuable hidden under the southern dirt and you seem to be the only one not knowing.
C) Have the guards remove the Felonsine so you may conduct business with the Ceodwellian instead.
