Umber Scale, or Umbra Scale, as it was preferred to be called by the Kimogila Fanatics, was an area of space in the Karthakk system. By the time following the Battle of Yavin in 0 BBY, the Kimogila Fanatics had conquered the territory, stealing it away from the Blood Razors and pushing them back to the other side of the Spine of Lok. The once-peaceful space system of Lok, by now riddled with war, often prevented civilians and freighters from passing through the area unharmed. A space station was located within the Umber Scale territory.
