I just calmly looked at them and said, "When the time comes, we can discuss the terms. You will all have a chance to trade with the Dwarven Kingdom, so there's no need to worry."
The moment that they heard this, they all knitted their brows once more.
After all, they could hear from the way that I said this that I wasn't planning on playing ball with them at all.
I was planning on upholding the agreement with the Dwarven Kingdom and sell as their middle man.
That meant that I wasn't going to give the other human kingdoms any chance to connect directly with the Dwarven Kingdom.
That effectively put a stop to their plans, so it was only natural that they were unhappy with me.
But I knew that there would only be more trouble by letting them connect directly with the Dwarven Kingdom.
