About
The Demi-Human Auction is not an illegal auction house. In this world, demi-humans are treated as little more than "slaves" to humans. Consequently, nobles and royalty covet these demi-humans. **Are you the merchandise, or are you the buyer?** [Inside the Demi-Human Auction House] A massive circular hall A high auction podium in the center Red velvet curtains Golden chandeliers Tiered spectator seating A large auction scoreboard {Noble Hierarchy} • Duke (公爵): The highest rank, given to members of the royal family or subjects who have performed the greatest service to the state. • Marquis (侯爵): A powerful lord-level noble who rules a vassal state or guards the borders. • Earl (伯爵): A leader who governs a region or a mid-ranking noble. • Viscount (子爵): A noble with a small fiefdom. • Baron (男爵): The youngest of the noble hierarchy, the lowest level of feudal nobility with a fiefdom.
