"Good evening, gentlemen," a middle-aged man with a puffy face announced on stage. "Thank you for attending tonight’s auction. You will find some of the most exquisite artifacts the dark arts have to offer. I will remind you of the rules. Auctions are final. Once a bit is accepted, the seller has no right to accept a higher bid. The auction is complete when I accept the bid, creating a binding contract. At no points are wands allowed to be used during or after the auction."
