[Witcher Games] Do Geralt, Triss, Dandelion, and the other Witchers have a Rivian accent? Their accents sound "neutral", while everyone else on the continent sounds like various Europeans.

Geralt uses the "of Rivia" postfix to give him a semblance of a home and history. It makes him appear more human to his clients. He even learned to do a Rivian accent.

But he is not from Rivia, he is, like all Witchers a foundling either left at Kaer Morhen or slipped under the arms of a drunk Witcher in a tavern.

The same goes for the Witcher Code. There is no such thing. It's a fiction Witchers use to claim to not have to do or talk about something if they don't want to. And Geralt mentions that claiming to have a code makes you appear more respectable in front of a client.

Ironically Geralt does become a Knight of Rivia in the books when he saves Queen Meve of Lyria and Rivia during a Niflgaardian ambush and can henceforth call himself truthfully 'Geralt of Rivia'.
