Khan's statement excited the guests. He had yet to name a price, but money wasn't a problem for those figures, and the item was worth it.
Safety had always been one of the nobles' top priorities. Few in the Global Army would dare to attack them, but that only applied to weaker parties. Infighting was common inside those massive families, so the representatives wouldn't refrain from purchasing additional ways of protection.
The noble guests in the hall could also benefit from an additional advantage. They had attended Khan's birthday to represent their entire families, but their loyalty was to specific factions and groups inside those immense parties. Purchasing Khan's magic item now would give them priority over their fellow family members.
