Giaca was a lush, wild, world in the Unknown Regions, which was largely unspoiled by civilization. Although it was not a homeworld or colony for any particular species, it was not without intelligent inhabitants. Besides the numerous types of wild creatures in its dense forests and massive volcanic causeways, Giaca hosted a few scattered outposts of survey teams and criminal hideouts.
Giaca was said to be home to an ancient surveillance station of a lost civilization. The outpost and the surrounding area were rumored to be extremely dangerous.
