The Underground Auction that take place in 2000, the same year as the 287th Hunter Examination, is notable for being involved in a series of violent incidents: On the night of September 1st, the Phantom Troupe attack the Cemetery Building to steal all the auction items, killing a large number of Mafia members and their clients in the process. Not knowing that the items were already removed from the vault of the building by the Owl of the Ten Shadow Beasts and are safe, the Mafia Community mobilizes a large number of members, including Kurapika and some bodyguards of the Nostrade Family, to chase after the Troupe to the Gordeau Desert.
