The following is a list of Carraya IV inhabitants.
These Klingons lived on Carraya IV until 2369 when Starfleet lieutenant Worf found their settlement. They performed ritual songs and lived with Romulans side by side, some of them also married Romulans. Following Worf's participation, several of the younger Klingons left the settlement and their parents to visit Qo'noS. (TNG: "Birthright, Part I", "Birthright, Part II")
These Romulans lived on Carraya IV together with the Klingon survivors of the Khitomer Massacre and their descendants. They guarded the camp and received orders from the camp commander Tokath. (TNG: "Birthright, Part I", "Birthright, Part II")
Makeup continuity Polaroids from this episode reveal that the fourth Romulan is female. During the dinner scene she was sitting next to L'Kor which might indicate a relationship as Gi'ral was sitting next to Tokath. The continuity Polaroid of Michael Moorehead features the note that he was replaced in the second part which was filmed in January 1993.
