Segmentum Ultima - Notable Regions: Grendl Stars - The Grendl Stars are a constellation of stars located on the far Eastern Fringe of the Milky Way Galaxy that were once known as the Wings of Sanguinius. They are now known to harbour the hyper-violent xenos race called the Barghesi.Ghoul Stars - This region of space is located beyond the furthest reaches of known space, northeast of the Eastern Fringe. This vast tract of relatively unexplored wilderness space was once home to a number of inhabited human worlds. However, an ancient threat, known only as the Pale Wasting in Imperial records, is believed to have been responsible for the destruction of these worlds' populations during the Nova Terra Interregnum. This accounts for the large number of Dead Worlds within the region. The Ghoul Stars region lies beyond the light of the Astronomican, which is used by Imperial Navigators to guide vessels while travelling in the Warp. Without the guidance of this vital beacon, Navigators are unable to sense its guiding light and are forced to navigate blindly. Navigators often refuse to travel into this region for this very reason, for it is extremely hazardous to do so. The Death Spectres Space Marine Chapter currently maintains a constant vigil to ensure that the inhabitants of the Ghoul Stars never again threaten the galaxy.Charadon (Ork Empire) - Charadon is the capital world of the largest and longest-standing Ork empire in the galaxy, also known as Charadon, which is ruled by the tyrannical Ork Warlord Snagrod the Arch-Arsonist, a particularly vicious and sadistic leader of a race noted for its generally vicious and sadistic tendencies.Octarius (Ork Empire) - Octarius is an Ork empire covering the Octarius Sector, an area of space almost as large as the Realm of Ultramar, centred on the Ork World of Octarius. It is ruled by a vicious Ork Warlord known as the Overfiend of Octarius.Realm of Ultramar - The feudal demesne comprising 11 worlds which is administered by the Ultramarines Chapter of Space Marines.Sautekh Dynasty - The Sautekh Dynasty is a Necron dynasty consisting of 80 Tomb Worlds. Its Crown World is Mandragora. This powerful Necron dynasty is currently ruled over by Phaeron Imotekh, "the Stormlord."T'au Empire - The T'au Empire is a rapidly expanding xenos stellar empire situated within the Imperium of Man's Segmentum Ultima, near the Eastern Fringe of the Milky Way Galaxy.Triplex Sector - The Triplex Sector is dominated by swathes of barren star systems, largely uninhabitable and empty. It is a wasteland of ore-rich asteroids and older, dying stars where a few scattered clans of Abhuman miners and prospectors try to eke out a living. However, it still contains some places of interest to the Imperium in the Eastern Fringe.Korianis Sector - Contains the Sub-sector Aurelia, home of the Blood Ravens Chapter of the Adeptus Astartes, and site of the three Aurelian Crusades.Elara's Veil - Elara's Veil is a massive, crimson-coloured nebula located somewhere in the Ultima Segmentum of the galaxy that is also an isolated sector of the Imperium. It is named after the legendary hero Elara, a significant figure in the mythology of the people of the Ocean World of Nemeton. Comprised of twenty Human-settled worlds, Elara's Veil falls under the protection of the three Chapters of the Adeptus Astartes known as the Adeptus Vaelarii, the "Sentinels of the Veil," which once included the Emperor's Spears, the Celestial Lions and the Star Scorpions before the latter was destroyed and corrupted by Chaos.
