Sentith was a Romulan male who was, in part, associated with the captors who held captive survivors of the Khitomer Massacre. He was living in seclusion on Carraya IV until 2369, when Starfleet lieutenant Worf found their settlement. (TNG: "Birthright, Part I", "Birthright, Part II")

Sentith was portrayed by background actor Ted Parker.
His speaking scene was cut from the episode. Tokath says that Sentith once wrestled with a wild morag to save a Klingon child.
