Butcher of Blaviken

Butcher of Blaviken is one of Geralt's aliases.

Geralt gained the moniker after what transpired in the story The Lesser Evil (Mniejsze z'lo).

In Blaviken, Geralt slew Renfri's bandits, as well as Renfri herself, in order to save the life of the wizard Stregobor. However, to the general populace, it looked like Geralt attacked them out of the blue.

The Witcher computer game
This title follows the amnesiac Geralt even during the game, especially in the Temple Quarter of Vizima.

A townswoman: "The Butcher of Blaviken's in town. If you see him, run!!"

Guard: "I know we needed a witcher to kill the sewer beast...but the Butcher of Blaviken?" Geralt: "What's the problem?" Guard: "I know who you are. The city guards are watching you. I'll hear of no humans being slain in this town." Geralt: "You'd hardly be the first to know." Guard: "Witty...What you want?"
