Bastior Sub-sector
From Warhammer 40k - Lexicanum
The Bastior Sub-sector is a Subsector within Segmentum Pacificus that contains many worlds and also a pivotal Warp Route, that the Imperium most hold at all costs.[1]
Such knowledge breeds fanatical devotion and selfless courage from its Imperial defenders and the Crimson Medallion of Bastior is the highest honour afforded to them.[1] Currently, the Sub-Sector is under heavy assault from the Tyranid tendril Grendyllus as part of the Fourth Tyrannic War and is a key front in the conflict.[2a] So far dozens of Bastior's systems have been devoured by the Tyranids.[7]
