- "I am not István!"
- ―Lorena Krasiki, to Bill Compton[src]
István was an unseen male vampire on the HBO original series True Blood. Originally from Hungary, István is the maker of the once innocent Lorena Krasiki, and was mentioned only on the episode "I Got a Right to Sing the Blues" in the series' third season.
István wasn't the most liked individual in the world. Especially when people found out he would "defile [them] in unspeakable ways".
István is originally from Hungary. He is the vampire who turned Lorena Krasiki into a vampire.
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. ("I Got a Right to Sing the Blues")
István is a Hungarian name and means Stephen.
- István could be a member of Sanguinista, taking into account his opinion about humans.
- István as a Hungarian name can be a reference to the infamous Count Dracula. As his original name was Vlad Țepeș, and Vlad is the Slavic version of the name István, and the infamous lord was born in Segesvár, Hungary. This is also in correlation with the facts and horror stories, that István/Vlad/Dracula was a sadist.
