You order the men to remain stationed in Western Luathbas, and with the order goes food, ammunition, medicine, clothes and all the soldiers need in everyday life.
884 AD, Mid-Autumn
The advisor approaches you as you read through the pile of morale reports from across the country.
"My Queen, the dwarves wish to talk with you." You blink and then move to the throne room, where the dwarves are waiting. You sit down on the throne and their leader, clad in purples and greens, steps forward, bowing slightly.
"Queen of Luathbas, we come here to offer our money to Treasury of nation of yours. We hear of many problems that haunt Luathbas and therefore, to see that our vital and most profitable trade route to East is maintained, we're willing to give you money."
"How much money?" The dwarf smiles.
"Double of what your gold mines produce coin per usual year." The courtiers gathered in throne room murmur.
"Or even four times that." He adds dramatically after a moment, causing only more murmuring.
"You want something in exchange, don't you, dwarf?" The leader of the dwarves nods.
"Indeed I do. For the double amount of money we wish for our merchants to receive a guarantee that for next fifty years not a single coin of profits will be taxed from them by your Treasury. The two-year small tax of course doesn't count, as such coppers can be easily afforded. For four times amount of money, we wish for Army of Luathbas to permamently guard and garrison our workshops and trading posts, and these we have twenty five total in Luathbas. A thousand humans would be required."
"Our Army is busy and small at the moment. Buy yourself some mercenaries instead." You quickly dismiss that one offer - in other times, it could be even called profitable.
As for the tax exempt guarantee however...
A) "I was in fact contemplating to tax you, so better go home and prepare your finances instead."
B) "So be it. An big influx of money for a tax exempt. We have a deal, dwarf."
