Viznik

Viznik is a former member of the cult of Richard Smallhorn. He can be encountered in the Překážka sewers and can give Adam Jensen the side mission SM02: Cult of Personality.

Background
Viznik was once a member of Richard's cult, a group who have been subjected to Richard's hypnosis technology involving the use of emitters to stimulate a person's brain to create an illusory communal experience. When there was a temporary signal failure in Richard's emitters, Viznik questioned Richard and was subsequently expelled from the cult. Despite being out of the cult and away from Richard's emitters, Viznik has not yet returned to a fully normal mental state, as seen by the awkward manner in which he speaks.

Deus Ex: Mankind Divided
Viznik will tell Adam Jensen that Richard has harmed him and the others, and will ask Jensen to investigate Richard's cult. Viznik carries with him the keycard needed to access the locked door leading to the cult's area. Obtaining the keycard from Viznik begins the side mission "Cult of Personality."
