The Second Great Cyrannus War, also known as the Second Great War, or the Republic-Imperial War, is a major intergalactic conflict pitting the Galactic Empire of Cyrannus, under the Oikoumene Emperor Tyrómairon, against the New Cyrannian Republic, led by President Apollo. However, outside Cyrannus, the Empire is opposed by a considerable coalition of anti-Imperial civilisations across the First Gigaquadrant—the culmination of years of confrontations between the Empire and rival powers.

The origins of the conflict date back to the Intergalactic War, when Tyrómairon—an ancient Oikoumene Lord dormant since the Apotheosis—reawakened, setting in motion a plan to reshape the galaxy under his rule. Orchestrating the First Great War between the United Republic of Cyrannus and their Confederate rivals, the Dark Lord brought the conflict to an end during the Battle of Orbispira, whereupon he dissolved the Republic, conquered the Confederacy and formed the Galactic Empire of Cyrannus with the support of the majority of the new Empire's war-weary population. Tyrómairon's age of peace, however, was opposed by remnants of the Republic and the Confederacy, both of which refused to surrender their ideals and freedoms in the name of order and security. Under the leadership of Apollo, the Republic remnants ultimately coalesced as the New Cyrannian Republic in 03 NE, beginning a period of detente which lasted until the Cyrannian Cold War toward the end of the Empire's first decade.

After nine years of mounting tension between the two powers, the Empire was the first to make a move. Any chance for Cyrannian Concordance dissolved as quickly as the worlds of the Mou'Cyran system, annihilated by the Empire in an open act of war condemned across the Gigaquadrant. Though it was successful in crippling the government and military of the New Republic, it rallied under the leadership of Apollo, who ascended to the Presidency to lead the Republic war effort—inaugurated by the destruction of the Cyrannic Imperial Battlestation and the outbreak of open conflict across Cyrannus and the Gigaquadrant.


Each of these conflicts is but one tiny piece of a larger whole, a war endless and inestimably larger. The Empire's crusade to rule the galaxy has not ended with the Fall of Vasuband. In truth, it has barely begun.

- Imperator Tyermaillin, 05 NE

During the Lost Eons, a timeless period prior to the formation of the Universe, the Oikoumene emerged under the wise leadership of Apolithanatár—the Lord and Vector of Light and the First Born of Valin'uvalyë. He was followed by the Vectors of Chaos and Order, who vied for control over the destiny of the Oikoumene. The Vector of Order, Tyrómairon, led the martial force of the Oikoumene empire, the Mornûnendur—seeking to bring eternal order upon the cosmos, by force if necessary. Since the disappearance of Apolithanatár, the Oikoumene strayed from the "Path of Valin'uvalyë", with the eternal battles between Chaos and Order corrupting their very being. During the Apotheosis and the First Return of Apolithanatár, civil war erupted, threatening to tear apart the very fabrics of space, time and reality itself. With the end of the conflict, the Oikoumene lords retreated—both Apolithanatár and Tyrómairon seemingly locked away for all eternity to follow.

The Cyrannus Galaxy evolved throughout the subsequent ages, during which time galactic governments such as the First Republic, the Federation of United Worlds and the United Republic of Cyrannus rose and fell. When extragalactics first arrived in the galaxy through a wormhole from the Quadrant Galaxies, the history of Cyrannus was forever changed. The Republic of Cyrannus became an intergalactic power and along with allies such as Rambo Nation and the Delpha Coalition of Planets stood together against threats ranging from the Trucinex, the First Cognatus Empire and the Xhodocto themselves. During the Intergalactic War, however, the future of the galaxy became intrinsically linked to its forgotten past.


The machinations of the Oikoumene Dark Lord Tyrómairon are central to understanding the origins of the Second Great War.

Awakened by Republic soldiers who happened upon his planetary prison, Tyrómairon rose to find the galaxy in conflict. Thus, he orchestrated the Grand Plan—the capitulation of Cyrannus through guile and the inauguration of an age of eternal peace and order under a single ruler—an Oikoumene Emperor. With the end of the Intergalactic War, Tyrómairon located and awakened his Mornûnenduran followers and began to influence galactic events as a power broker, known to but a few of the galaxy's most important figures. The culmination of the Grand Plan came with the outbreak of the First Great Cyrannus War, between the Confederacy of Allied Systems, an alliance of worlds seeking independence from the Core and against the Republic's claim as the galactic government of Cyrannus. Ensuring that neither side came close to achieving victory, Tyrómairon subtly began transforming the Republic into an increasingly militarised power, under the nose of beleaguered President Apollo. The war finally ended three years later with the formation of the Galactic Empire of Cyrannus, with Tyrómairon as the Galactic Emperor.

Three years later, the former President Apollo, had successfully negotiated with the Empire to allow for the formation of the New Cyrannian Republic far from Imperial borders. Though the period of detente which followed, characterised by undeniable tension, though also by occasional cooperation, led some to advocate for Cyrannian Concordance between the two powers, the outbreak of the Cyrannian Cold War in 06 NE dampened such hopes. During the Cold War, the actions of Aoirtae Valaeris, Kara Inviá and Master Ryen, culminated in the return of Apolithanatár—seemingly prophesied by the Annals of Valin'uvalyë to stand against the Darkness of Tyrómairon. In his wake, the Aldárae Order, an esoteric order dating back to the First Republic, was reformed as a beacon of Light to oppose the Empire. This, together with the Republic emerging strong from conflicts such as the Neraida War, led to the escalation of the Cold War and the formulation of the "Operation"—a first strike against the Republic. In 15 NE, a month after the Dissolution of the Imperial Senate, the Empire attacked the Republic capital Mou'Cyran—sparking the outbreak of hostilities across the Gigaquadrant, centred on the battle for control over Cyrannus, both between the Republic and the Empire and between the ancient Vectors of Order and Light.

Course of the WarEdit

Opening Stages (15 NE - 16 NE)Edit

I pledge to fight this tyranny. I pledge to fight your rule of atrocity and I pledge with every fibre of my honour, my life and my very being, that I will fight to bring about your destruction and the abolition of the Empire.

- President Apollo, during the Capricaerón Address

The conflict began in earnest with the Battle of Cadian, fought immediately after the Mou'Cyran Cataclysm. Republic forces under the command of Fleet Admiral Willelmus Cretacea and under the direction of the newly installed President Apollo, assaulted the Cyrannic Imperial Battlestation on the fringes of the Cadian System in the Outer Rim. As the Empire prepared to fire on the interim Republic capital Capricaerón, Republic and Aldárae forces managed to destroy the station, killing Grand Mandator Taev Vosaetiur and severely limiting the Empire's capacity to win a total and immediate victory against the Republic. Though the President sought to immediately capitalise on the victory to weaken Imperial sectors in the Northern Outer Rim, now free from Vosaetiur's stranglehold, the Empire responded with a massive invasion of the Republic's territories in the Coru Secundus region.

Second Battle of the Mou'Cyran Remnants

Republic and Imperial forces fight to the last ship to claim the Mou'Cyran System.

Commanded by Fleet Admiral Tharnak Adraci, the Imperial First Battlefleet struck at Thaehos and multiple other worlds along the now non-existent Neutral Zone, with many openly declaring for the Empire, alternatively through the machinations of Imperial Intelligence, or fear of the mighty Imperial fleet. Amidst the remnants of the Mou'Cyran System, the Empire and the Republic clashed twice in the largest battles of the conflict thus far, with the Republic fighting fiercely to prevent the Empire from gaining a foothold in the system—the gateway to the great hyperlanes of Republic space. Despite heavy losses, the Imperials ultimately emerged victorious at the Second Battle of the Mou'Cyran Remnants, dealing yet another crushing blow to the Republic Navy, which scattered to defend the few fortress worlds left untouched.

Simultaneously to the Battles of the Remnants, Grand Admiral Valindor Palenix rallied a massive fleet to the Rambo Capital, where he proclaimed Rambo Nation under his protection, keeping the turbolasers of the fleet fixed on Tirithsilliana to ensure High King Rambert Ramveral's loyalty to the Empire. From the Capital, Palenix directed Commodore Sorondil to quell the Allied Terran Republic's colonies in the Quadrants—the first of many battles in the Wormhole Campaign. The campaign spread to the Milky Way Galaxy, where Imperial forces led by Grand Admiral Daeron Siruliulus launched a massive attack on the Defensive Systems Bloc, seeking to prevent them from aiding the beleagured Republic. The Empire utilised similar justification to begin a renewed assault on extragalactic civilisations such as the Indoctrinate Collective within Cyrannus, conquering the Collective colony of Narsul and crippling the Terran military in Cyrannus with an assault on Amphryssos. The New Republic, still reeling from the Cataclysm and later, the Republic Day Attacks was unable to aid their allies, with President Apollo struggling to form a government amidst the chaos.

SGCW Battle of Coruanthor

The Battle of Coruanthor proved to be the most destructive conflict of the early Second War.

With the fall of the key Republic stronghold of Coruaan, the Empire had all but secured the central sectors of Coru Secundus, though faced continued opposition in the extreme galactic south, where the campaign to rid Cyrannus of the United Persan Descendants, the Mendel Pact and the Waptoria Alliance of Species was slowed by an Imperial defeat in the Battle of Frenal. Similarly, the Unified Order of Cognalorilos began reclaiming lost Republic space beginning with the Second Battle of Manánnan, though their progress was impaired by a crushing defeat at the Battle of Cognethril. In the north of Coru Secundus, the First Battlefleet under Admiral Adraci continued seizing world after world along the Republic Hyperlane, ultimately sparking the Battle of Coruanthor.

The campaign for control over Coruanthor would last for much of 15 NE, with both the Republic and the Empire committing vast portions of their respective militarises to claiming the ecumenopolis. Simultaneously, the Empire began an invasion of the Terran Republic's home territories in the Milky Way, with the Battle of Tírnanóg resulting in a costly stalemate between Imperial forces and the Terrans and their Apalos allies. In the Quadrants, the military of Republica Elen'Nanethia suddenly ceased active coordination with the bulk of the Republic Navy, with Praesator Adelheidis declaring independence in open defiance of President Apollo's flailing administration. Her call to arms against Apollo's government was heard throughout the crumbling Republic, coming at the worst possible time for the Capricaerón government.




  • In a Xeranbha-dominated alternate 1250 NE, Aquillius Cretacea of the Cyrandia Republic mentioned to Helo Roslia that the Star Destroyer Aeolus saw service during the Second Great War, which was fought until at least 245 NE. However, given that Mou'Cyran was not destroyed in that timeline, the conflicts diverged considerably.


  • Permission is required from Cyrannian prior to involving your fiction in the conflict, which includes both direct and indirect involvement. The other coordinators are OluapPlayer and Dinoman82.
  • The Second Great Cyrannus War is a conventional conflict, battles will be fought fleet-to-fleet, army-to-army, character-to-character over individual planets and systems. As such, the use of superweapons, as well as large scale hyperspatial warfare—involving the destruction of fleets, worlds or systems and not including actual battles in hyperspace and interdiction technology—will be exceptional cases that must be discussed with the owners of the belligerent factions in question.
