Warhammer 40k - Lexicanum β

Galactic map of Ultima Segmentum

The Ultima Segmentum is one of the divisions of the Galaxy known as Segmentums of the Imperium and is by far the largest. It is located to the east of Holy Terra, and its Segmentum Fortress is located at Kar Duniash.[1] Notably it contains the Ultramarines empire of Ultramar, the Tau Empire, and along its border is the Eastern Fringe.[Needs Citation]

Following the conclusion of the Thirteenth Black Crusade and the rebirth of Roboute Guilliman, much of north and northeastern Ultima Segmentum has become stranded within Imperium Nihilus.[2]
