History:
Carraya System, Near the Romulan/Klingon border, the location of a secret Romulan prison camp. This camp, established several months after the Khitomer massacre in 2346, imprioned nearly a hundred Klingon prioners who had been captured, unconscious, from a perimeter outpost. Romulan officer Tokath sacrified his military career in a humanitarin gesture to establish the Carraya camp where these prisoners could be incarcerated so that the Romulan government would not execute them. In the years that followed, a peaceful coexistence devloped between the Romulan jailers and their captives, whose Klingon warrior ethic would not permit them to return to their homeworld after having been captured in battle.
TNG "Birthright, Part I and II"
The exterior of the prison camp was designed by Richard James, from which a model was built that was the basis for a matte painting executed by Dan Curry. (Production designer James was, of course, also responsible for the full-size interior sets, as well).
