The Borsodi Brothers' Auction House is an impressive three-story building in the Free City of Novigrad, belonging to the Borsodi Brothers from the Borsodi family. It's located on the square on Main Street, in the most representative part of the city. Auctions were held only once every three months, on Fridays.
Hearts of Stone expansionEdit
In the first expansion for The Witcher 3: Wild Hunt, Vimme Vivaldi tells Geralt that Radovid V of Redania made a deal with Horst Borsodi if Horst moved his auction house near Radovid's kingdom pearl - Oxenfurt. Radovid would then grant Horst a preferential tax rate of zero percent.
The building in Oxenfurt is only two-stories high compared to the one in Novigrad, but this one has an underground vault to compensate. The underground vault has a trap plate right after the vault door leading to a pit full of Arachnomorphs, as well as a hidden exit at the end of the vault.
