After the tour was over, S'aleth was required by her father to take Erich out to dinner. This was both a diplomatic venture in itself, but more importantly was a power play on behalf of Governor S'varin. For starters, S'varin had come to understand that Erich was more than just an adjutant to the Deputy Leader of the Germanic Star-Empire.
Though the Dvrakian politician didn't know exactly what Erich's role was, or why he was dispatched on this journey, he wanted Erich away from further diplomatic discussions which were to be held later that night.
Instead, he had tasked his daughter to escort Erich around the city and take him out to dinner for the duration of the night. She was also to report anything and everything that Erich may have done on their journey.
