The auction for the dragon parts was set for two days after the banquet.
Most of the nobles had already arrived for the banquet, but there were a few that were straggling behind because of various circumstances.
That was why Amy had decided to wait another two days for them to arrive.
She wanted to get as many nobles here as possible, but she also wanted to maximize profit from this auction. That was why she chose to wait this extra time so that as many paying customers could arrive as possible.
But it wasn't as if she could wait too long.
If she delayed for too long, it was only natural that the ones that were already here wouldn't be happy.
Not only would it mean that there would be more people here to compete with them, it would mean that they had wasted their time coming this early. These nobles naturally would not be happy about their time being wasted.
They were nobles in the first place, they naturally regarded their time as more precious than other people's.
