Vienne

Vienne is a former member of Jad Karadin´s gang and a elven sharpshooter.

Before joining Karadin, she was also a guerilla-fighter of the Scoia'tael until her unit got defeated, leaving her the only survivor of this incident. Out of a lack of options, she joined Karadin´s assassins.

Vienne can be encountered in the Seven Cats Inn where she is getting drunk as Geralt and Lambert enter the tavern.

She can provide useful information for the quest Following the Thread as she makes it clear that Karadin´s gang was, if one thing, a group of trained assassins rather than one of debt-collectors. This can help later to choose wether Karadin should be spared or not.
