As you wander around, heading back to the room you arrived in you pass the platform/stage with its guards. The area around it stays mostly clear due to the rather surly disposition of the guards that are in full armor with helm so it is impossible to determine their race, save they are humanoid. As you meander you catch another snippet of gossip.
Goblin says:
"The Boss will be the guy bidding up the price."
Piecing together things you have heard and filling in a few gap you gather there will be an auction some time soon. But you get the impression it will not be today but within the next several days. The invitations are likely for those deemed strong enough to bid on it, and their forces. The Expedition might want to learn more about this.
Upon arriving back at the building you arrived from you are a bit put out when you see a trail of smoke drifting out from one of the windows and several goblins loitering around the front of the door.
