Foretta IX

Foretta IX is a designated minor Fortress World in the frontier-east of the Ultima Segmentum, formerly serving as a civilized world. Its history with the Cadian 101st regiment has a considerable impact on their culture, and its recategorization as a Fortress world was in response to the sector's discovery of the alien T'au Empire, and has focused most Imperial forces to blockading the T'au from the rest of the sub-sector.
