The Treasury gains some, the dungeon cells lose one. A good trade, that.
962 AD, Summer
A war trumpet of Dahnia greets you one morning. The envoy of King Tinwulf II arrives wearing chainmail and the banner of his master.
"Greetings, Grand Duke of Tven, Estwalf, choosen by the Council!" He greets you hurriedly in the audience room. "Our beloved lord and master, King Tinwulf II, has grown tired of the Eist raiding of your borderlands, especially when in one such raid his cousin was wounded. He therefore calls to arms his subjects, to beat the zealots of Eist back to their homelands. King Tinwulf requests as many footsoldiers and cavalry as you can provide."
"You could also lead the men yourself, my liege." Says the advisor, leaning towards you. "That would boost your prestige and the morale of your men, too."
As for the matter of support...
A) We can spare only few soldiers, unfortunately.
B) Time to send our Army to conquer Eist. Onwards!
C) Soldiers we cannot give, but how about some war supplies?
As for your presence in the war...
A) TIME FOR FAME AND GLORY!
B) Imma stay at the palace, yo.
//If you pick C as first choice, do not choose anything from second list.
