The Trianii Space was the region containing the Trianii's homeworld, Trian, and their colonies. This faraway region was a freestanding subsector, it was never part of the Galactic Republic or the Galactic Empire.
The Trianii Space was a regional rival of the Corporate Sector. The Corporate Sector Authority offered to annex it but the Trianii always refused. The CSA attempted to forcefully annex several Trianii colonies, but met resistance from the Trianii Rangers.
