Delta-Beta-Tau-3 is a mobile station located in the Thule Sub-Sector. Nominally, it is a jointly run facility of the Navis Nobilite and the Adeptus Astronomica, officially tasked with studying the Pandaemonium and the the Warp routes of Askellon. Since its inception, no one other than the Navigator houses and those of the Adeptus Astronomica have been allowed aboard, but numerous unmarked ships have been seen providing cargo of some sort to the station outside of the usual supply drops. Attempts to follow these craft have resulted in numerous missing ships and fatal accidents for the pursuers.
