Segmentum Exterioris stands as once of the least understood, and least tamed regions of the Andromeda galaxy, and barring segmentum Adniliho is one of the least inhabited regions of the galaxy. Since the beginning of the 2800s, a large bright spot known as The Glow of Exterioris has dominated the deepest regions, understood by Andromedan natives to be the epicentre of the shockwave that fragmented the galaxy with hyperspatial fissures, and made worse by The Grand Teyan Empire's use of hyperspatial weapons that has left nearly thirty five percent of the entire segmentum without hyperspace.
Since then, Exterioris has gone from the most unexplored regions to being the most difficult to explore, as the segmentum where the Shattering originated, the fissures in the segmentum are densely positioned enough that large areas exist deemed inaccessible to most forms of FTL and hyperspace-based travel.
Exterioris was colonized by the Psal'Jinnai Symmetry around 11,880,000 BCE, serving as the seat of their power in the Xonexi Cluster until their fall. During this time, the Yphreli and Belphrim were both engineered by the Psal'Jinnai as part of the next set of hosts for the extrauniversal minds of their kin. However, the Asymmetry's attack on the Psal'Jinnai left their civilization in ruins, with only their constructs and children being left behind.
After the fall of the Psal'Jinnai, the segmentum ceded to the tyranny of the Gros, until their eventual fall and the collapse of the Stratocracy of Karnagtah in 2793. Following this, the region was greeted with realtive peace, until yet another power rose, aiming this time to destroy all other powers in the region. This new threat took the form of The Grand Teyan Empire, whom the Muaran Resistance have responded to in a brutal gurrila war that has devastated planets, such as Sulsua, the homeworld of the Mithadorn, one of the races whom rose up to defend their stakes in the segmentum.
Segmentum Exterioris is currently dominated by a massive area of hyperspace-denied space known as The Chasm, which encompasses approximately thirty five percent of the region, and covers much of the former territory of the Mithadorn Republic, and several parts of The Glow of Exterioris, which denies further hyperspace routes in the segmentum. Making up the "north east" of the Andromeda Galaxy, it borders on the Xhodocto-controlled segmentum Adniliho, and segmentum Umbra.
|The Chasm is a large section of Exterioris within which conventional hyperspatial travel is impossible, with Teyan Krasnikov tubes being the primary, and only, means of superluminal travel between systems. The Grand Teyan Empire dominates this region as a result, though the Muaran Resistance and Mithadorn Remnants continue to fight back throughout the region.|
|Serving as the region in which the Muaran Resistance operates from, the Muara Sector and affiliated territory is consider the forefront of the Teyan Subjugation War. Many of the Segmentum's empires have found countless civilians fleeing to the area to take refugee under Resistance protection. The entire sector is named after this fact, and it's prior name is very rarely used as a result. It is home to a significant portion of the former Yphreli Glaciation, whose occupied capital can also be found in the sector.|
|The border sector between Exteroris and the Dominion-dominated Segmentum Adniliho. It is unaffiliated with any major empire.|
|Like the border with Segmentum Adniliho, the border with Umbra is unaffiliated with any major empires, though is more heavily trafficed than the segmentums other regional boundries, due to the lack of Dominion presence.|
|Home of the now-defunct Belphrim Republic and the site of a research zone jointly operated by it and the Yphreli Glaciation, the Antecedent Sector is marked by a high concentration of Psal'Jinnai constructs. Since the conquest of both states by the Teyan invaders, the zone has fallen under Teyan control, though the Xonexi Conduit Mind has reawakened and now resists their attempts to take control of formerly dormant Symmetric constructs.|
|Named after the primary pirate trading hub in the region, Kula'Tion was a noted zone for merchants to avoid in Exterois, prior to the Grand Teyan Empire's invasion. Now little remains in the sector, as the Teyan occupiers have razed many of the unruly pirate strongholds to the ground.|
|Formerly dominated by the Psal'Jinnai and, more recently, the Romanian Commonwealth's Andromeda colonies, the Shaluso Sector is one of the less pirate-infested regions of Exterioris, though several Combines of the Saviki Metafleet have recently entered it to scavenge in the wake of the Teyan Blitz. Though not significantly impacted by the hyperspace-denying Godspade, Shaluso is currently under the control of the Teyan, with Romanian remnants within the Muaran Resistance prioritizing strikes against them in this region. It is named for the Psal'Jinnai fortress-world which spearheaded the Symmetry's initial forays into Andromeda through this sector.|
|Largely shielded by the Muara Sector in the Teyan Subjugation War, the Aniku sector functions as a back-line in the conflict against the invasion of the Grand Teyan Empire. Much of its territories, while without hyperspace due to the Teyan's actions, functional Krasnikov tubes still exist in the region, allowing outside aid into the segmentum, and providing crucial supply lines for soldiers, both local and foreign to the segmentum, fighting in the war. Within it are a number of systems formerly controlled by the Yphreli.|

Exterioris has little in terms of an economy. Without any major hyperpowers with interests in the region, excluding the one trying annihilate everyone else, and the overabudence of pirate raiders, little trade actually occours between the local empires. Much of what little economy there is, as a result of this, typically involves weapon sales and black-market slave trading between pirate factions.
The overall culture of Exterioris can be described as lacking. Excluding the Muaran Resistance and its allies, and Grand Teyan Empire, the only factions common across the region are pirate fleets. As a result, Exterioris is commonly viewed as pirate-territory, and a simple battleground between the invading Teyan, and their enemies. Culture within the segmentum matches this approriately, with local civilisations almost unanimosly opposed to Teyan rule.
The Progeny races (those descended from or influenced by the Psal'Jinnai) have recently begun forging stronger cultural bonds due to their common heritage, and Progenic sociopolitical tendencies have gradually seen expansion across the Segmentum. However, with the Grand Teyan Empire attempting to bulldoze most native societies, whether this will continue through the partly Progeny-dominated Muaran Resistance remains to be seen.
