- "I am not István!"
- ―Lorena to Bill[src]
He used Lorena to entice men into her chamber, and then he would "defile them in unspeakable ways" according to Bill Compton. It is unknown why Lorena left him, but it is most likely because she had fallen in love with Bill and didn't want any harm to come to her progeny. István's current whereabouts, and whether or not he's still alive, are unknown.
István has only been mentioned on the True Blood series.
