You order the Suiso delegation in. They wear linen, brightly colored, and fur caps on their heads. Their hands and fingers, long and thin, are adorned with bone rings and bracelets.
"Greetings, King Syrus of Surinthomus! We have come to warn you of a great calamity that is lurking to befall you and your peoples!" The courtiers gathered in the room immediately start murmuring, whispering and grumbling.
"And what would that be?" The Advisor says as the delegates bow their heads.
"A great calamity!" Says their leader, then takes his hat off, exposing his sparse, messy, dark blonde hair. "You see, ours is the faith of the Waters, and we have oracles - shellsingers - who venture into the depths to procure shells of specific kind, and then they listen to their murmur, discerning prophecies of both great and mundane import. Our King, Tuomas, has recently asked the greatest of Shellsingers, to advise him on the future. Imagine his surprise when he was told a prophecy that would affect not his kingdom, but someone's else!"
"What's the prophecy?" You ask loudly, and silence enters the place, as your courtiers are, of course, very interested in it as well.
"Here it is, our King ordered us to memorize the lines. It goes like this: When the young star rises in the east, a bloated, old one falls. When the trees resume moving west, the ice giant rages. When the young star loses part of its luster, it crashes upon its domain in voracious flames, causing great stress, and famine, and death." Your courtiers resume their murmuring, but the Advisor silences them with his staff.
"Let me elaborate, what our King and his advisors believe this means." The leader of the delegation says. "The first part, is about you. You, a rising star, have cast down the bloated, corrupt Usurper - the old star. Few years after your peoples started sending lumber down the river - to the west - there was one winter of terrible blizzards that even our people struggled against. And recently, as our King has learned, you have lost your son in terrible tragedy - you have lost part of your luster."
"And the crashing part?" The leader of the delegation shakes his head.
"We do not know what that might be. But our wise men had some ideas and each is worse than previous, up tp and including the Sun herself falling down upon your kingdom. King Tuomas ordered us to sail upriver, to your Kingdom, and warn you, as the shellsingers say that if one part of the prophecy will cease to be true, so shall it will never not come to pass in full."
"Cease sending lumber down the river, to western kingdoms, is what you mean!" The Treasurer speaks up, glaring at the westerners.
"You cannot bring neither Usurper, nor your son, back to life, King Syrus." The Suiso diplomat states the obvious. "So this is the only way!"
A) "Thank you for this warning. We shall cease lumber trade immediately!"
B) "Listening to seashells and divining the future out of them is the stupidest idea I have ever heard about. Begone at once, and trouble my people no more!"
C) "You've ventured so far to warn us despite not knowing much. Your King and your people ought to be rewarded - with precious copper and lead!"
D) "Call for the Archdruid! What do the omens of the Creator and voices of the spirits have to say about this?"
