The Bellarb Sector
The Bellarb sector is located on the eastern fringe region. The Astronomican is very weak and distand.
Bellarb has a scattering of imperial outposts and see Ultramar traffic from time to time, but calls for help to the Emperium largely goes unanswered.
No ships headed to the Bellarb sector has returned for almost a month now. Astropaths hear nothing. Something is going on.
