The Mid Rim is a sprawling galactic region of the Cyrannus Galaxy located between the prosperous Inner Rim worlds and the expansive Outer Rim. Secluded from the politics of the Core, yet largely isolated from the lawlessness of the Outer systems, the Mid Rim can be characterised as a microcosm of the galaxy as a whole, with a relatively stable interior, and a harsh, unrefined exterior. The Mid Rim is filled with millions of inhabited worlds, many of which are the cradle worlds of some of the Cyrannus Galaxy's most influential species, such as the peaceful Apationagtus of Apheria, and the expansionist Thanatyrannus of Maastrichtia.

In the earliest days of modern galactic exploration and colonisation, the Mid Rim represented the galactic frontier, with the establishment of Core colonies such as Taracondor, Coraaxas and Jurasican inaugurating an era in which a regional culture grew as a confluence of Libertus and native Mid Rimmer customs and traditions. Trade from the Core and Inner Rims led to the development of prosperous worlds such as Melenor and Cruandai, while the serene beauty of worlds such as Bonderae and Elen Thalorae attracted visitors from across the galaxy. However, the territorial ambitions of the Thanatyrannus has darkened an otherwise stable past. Striking from the Maastrichtia Sector, the Sublime Tyranny established a vast imperial regime, hampering Federation efforts to expand into the western sectors of the Mid Rim.

In modern galactic history, characterised in the Mid Rim by the normalisation of relations between the Thanatyrannus and the Core, the region endured the brunt of the Great Cyrannus War, when thousands of Mid Rim worlds defected from the United Republic of Cyrannus to join the Confederacy of Allied Systems. Simultaneously, the northern reaches of the Mid Rim became heavily influenced by Quadrantia culture, with the establishment of the Rambo colonial sector at New Ramhall. When the Empire was formed at the end of the conflict, the Mid Rim was treated relatively well by its new Imperial masters, unified almost absolutely under Tyrómairon's rule. Rewarding the largely loyalist region with improved infrastructure, as well as a surplus of Imperial academies—particularly in the highly developed Taracondor Sector—much to the chagrin of the region's few New Republic sympathisers.



The Fall of the Temoin Empire took place within the Mid Rim.

For millennia, the Mid Rim represented the galactic frontier to the more populous inhabitants in the Core. Prior to the charting of the Outer Rim, the Mid Systems were referred to simply as the "Rim", a vast and untouched region of space home to mysteries and dangers unimaginable. The Great Temoin Empire was the first great civilisation to hold sway over the region, countless millennia before the rise of the Empire. However, having grown corpulent under the strain of their vast empire, the Temoin were destroyed by Oikoumene AI, programmed by their creators to ensure that despotism would not bespoil their mother galaxy. Nevertheless, the Temoin would leave behind hyperspace technology which would be used to inform further research into faster than light travel by brave explorers from the Core.

During the era of the First Republic, the region was a hotbed of conflict between the Republic and various factions, including the ancient Phaedric Empire, as well as civilisations suspicious of the Republic's expansion outward from the Core. During the reign of Praesator Riantontine I, the Republic came under the sway of religious extremists, who targeted independent Mid Rim worlds in a series of bloody Crusades which lasted for centuries. Ultimately, however, the discovery of the Miluiel, and, according to some scholars, the First Aldárae Order, brought about an end to the cult, and its genocidal crusades in the Mid Rim.

After the devastation of the Second Nagith War, and the collapse of the First Republic, the expansionistic Thanatyrannus came to power, forging an empire known as the Sublime Tyranny of Maastrichtia. The Thanatyrannus, prideful though honourable, offered comfortable subjugation to those who bent the knee to the Rex, and abject destruction to those who refused. Their campaigns in this regard would lead to the devastating Mid Rim Wars, fought during the sixty first century prior to the rise of the Empire. Defeated by a coalition of species led by the Ausare of the Inner Rim, and the Libertus Mid Rim stronghold of Coraxaas, the Thanatyrannus would begin to cease their campaigns against defenceless civilisations, and began peaceful relations with the newly established Federation of United Worlds.

The Mid Rim became a bastion of power for the United Republic of Cyrannus upon its formation in 53 NE, and upon the opening of the galaxy to extragalactic civilisations after the Trucinex War, it became home to an expansive network of colonial sectors governed by aliens from across the First Gigaquadrant. Though some species, such as the Thanatyrannus derided these newcomers as interlopers, the peaceful Apationagtus, Cargura and Ermitant welcomed them gladly, and began regular trade as equals. The most prosperous of these sectors was controlled by Rambo Nation, from their galactic capital New Ramhall.

The site of countless battles during the Great Cyrannus War, the Mid Rim was hotly contested between the Republic and the Confederacy of Allied Systems. Though the Republic controlled the bulk of the Rim, the Confederacy captured numerous sectors during the early weeks of the war, seeking to cut off Republic reinforcements seeking to defend the outlying systems. By capturing the critical hyperlane known as the Reach, the Confederacy held sway over some of the Mid Rim's most influential worlds, such as Bonderan, Corenor, Taracondor and Elen Thalorae. Other systems defected through political means, with the Sylvamiman orchestrating the secession of the Forenus Sector during the second year of the conflict. The Mid Rim would remain a Confederate stronghold for the duration of the war, though the bulk of their defences were destroyed during the Battle of Taracondor prior to the final battle at Orbispira.

Battle of New Ramhall 12

The Empire ousts Rambo Nation during the Battle of New Ramhall in 01 NE. However, upon the signing of the Nim-Glaré Concordat, they were permitted to return to their worlds.

Under the Empire, the entirely of the Mid Rim fell under the crimson Imperial flag. In order to consolidate its power, the Empire conquered the extragalactic territories of the former Republic's allies. Only the Oligarchy of Praetinna was spared, when the Draconis inhabitants, led by Geleriva Delsacrian, agreed to swear fealty to Emperor Tyrómairon. Though mistrusted initially, the Oligarchy proved loyal and influential members of the Empire, becoming key players in Mid Rim politics. Upon the signing of the Nim-Glaré Concordat, the Rambo would be permitted their old worlds once again, as members of the Empire.

In recent years, with the establishment of the New Cyrannian Republic, most worlds in the Mid Rim upheld their loyalty to the Empire, grateful for the establishment of vast Imperial academies, and the improved hyperspatial infrastructure. Nevertheless, upon the outbreak of the Second Great Cyrannus War amidst the fires of the Cataclysm, some have begun to doubt the Empire's commitment to order and security.





The rustic beauty of the Apationagtus homeworld of Apheria is known across the galaxy.

  • Affiliation: Empire
  • Sector: Apherian Oversector
  • Terrain: Dense forests
  • Population: 3.1 billion
  • Sentient Species: Apationagtus (97%), Other (3%)
  • Government: Constituional monarchy
  • Major Exports: Manufactured goods, foodstuffs
  • Major Imports: Starships, raw materials

Apheria, the homeworld of the Apationagtus, is located in the Heartworld region of the Apherian Oversector, located along the Perliama Hyperlane close to the border with the Outer Rim. Though strategically located close to the Rambo Nation colonial sector, and thus benefits from lucrative trade from the Quadrant Galaxies, Apheria has largely enjoyed lasting peace throughout its time on the galactic stage. Perhaps such a fact is unsurprising, for the peaceful Apationagtus evoled within its endless golden woods. Blasted by its system's binary suns, Apheria is generally unsuited to non-reptilian life, though saurian species such as the Libertus and the Cavaneu can generally live there comfortably.

The Apationagtus evolved from tree-dwelling theropods in Apheria's dense equatorial forests and as they developed into a sentient species, they discovered countless Oikoumene relics scattered across their world. The first of these relics, known as the Kirk'ne'son Obelisk, propelled Apationagtusi technology forward over two centuries, illuminating the existence of alien species beyond the celestial halo. The Apationagtus soon made first contact with an Ermitant trader ship plying the Perliama Hyperlane, and became introduced to wider galactic society. Joining the Federation of United Worlds, Apheria benefitted from constant trade with the other worlds of the Mid Rim, becoming something of a power broker in Rim politics. A loyalist world during the Great Cyrannus War, the people of Apheria tended to be among President Apollo's most loyal supporters, and provided him with a vessel known as the Last Hope during his escape from the Empire.

During the Imperial era, Apheria came under the rule of Grand Mandator Aporyan, a fair and benevolent man who made Apheria the de facto capital of the Galactic Empire within the Mid Rim. However, the planet's claim on galactic importance disappeared over night when Aporyan resigned in 13 NE. Though it remained prosperous due to its location along the Perliama, the planet's New Republic sympathies earned the peaceful planet the Empire's baleful glare.


  • Affiliation: Empire
  • Sector: Coraaxas Sector
  • Terrain: Plains, forests, mountains
  • Population: 987 million
  • Sentient Species: Libertus (94%), Other (6%)

Referred to as the Defender of the Rim, the ancient world of Coraaxas was once an outlier colony of the First Republic, where it gained a reputation as one of the ancient Republic's most prized fortress worlds against incursions from the Nagith or Phaedric Empires. Though the planet itself has a population below a billion, it has been the seat of military prestige for millennia. During the reign of the Cyrannian Federation, Coraaxas played a similar role in reinforcing Federation borders against the Thanatyrannus. Steeped in the naval tradition of the galaxy, while Coraaxas has never reached the grandeur of Cyroenia or Scorpiae's shipbuilding capabilities, it's naval academies were counted among the best outside the Core.

A key Republic fortress world during the Great Cyrannus War, Coraaxas was attacked twice by the Confederacy of Allied Systems, though the presence of one of the Mid Rim's largest defence fleet, as well as unexpected reinforcements from the anti-Confederate Thanatyrannus, resulted in a decisive Republic victory during the Second Battle of Coraaxas, three weeks before the end of the war. When the Galactic Empire rose to power, Coraaxas was honoured as a bastion of the naval tradition cherished within the new hyperpower. Imperial Mandator Siron Tarkolis presided over a renewal of the planet's military prestige, making it his personal base of operations in policing the systems of the southern Mid Rim.

When Grand Mandator Apoyran resigned as the governor of the Mid Rim, Tarkolis ascended to the role, much to the delight of the native Coraaxans, a people proud of their planet's role in providing peace and stability to the Mid Rim. Such is the attitude of many Coraaxans, that outsiders often remark that unless one has proven themselves in the navy, they are not worth the effort. The planet itself is unremarkable, being relatively small and not housing any large cities other than the Bastion—the planetary capital and home to its prestigious academies. Though the planet is staunchly loyal to the Empire, Coraaxan shipwrights are responsible for the construction of the CC-line of vessels, ranging from blockade runners to diplomatic Consular-class corvettes. Contracts for the creation of such vessels are often outsourced to pro-Republic worlds in Coru Secundus, where they find themselves in the service of the Republic Navy, or, to the considerable chagrin of a typical Coraaxan, the Cyrandia Resistance.
