Prince Solomon of the Kaiser Empire.
There were already close dealings between the Empire and the Federation, especially on trading and commerce aspects. Both sides needed various things, and they both tried to contain the other. The Federation needed resources while the Empire needed technology. There would always be constant competition in places where humans existed, and this wouldn't change unless it was something related to mankind's extinction.
In the past, the Federation had consistently refused to give in and created many difficulties. When faced with benefits, however, the various clans definitely began to push in the background, leading to preliminary approval. All of this wasn't very important. The most intense point was the internal competition between the clans themselves. A massive amount of profit came from this trade, and in the end the Stuart clan had won.
