[[Image:galaxy_map_segmentumtempestusgalaxy map segmentumtempestus.jpg|thumb|right|300px|Galactic map of Segmentum Tempestus]]The '''Segmentum Tempestus''' is one of the [[Segmentum|Segmentums]]s, divisions of the [[Galaxy]], of the [[Imperium]]. Its [[Segmentum Fortress]] is located at [[Bakka]].{{Fn|3}} The Segmentum is roughly organized organised into 200 light-year cubes, each of which is designated as a [[Sector]]. Free from much of the [[Chaos]]-related problems of the Imperium such as invasions from the [[Eye of Terror]] or [[Maelstrom]], Segmentum Tempestus instead suffers from [[Xenos]] invaders and raiders.{{Fn|4}}
