Inaeon System

The **Inaeon System** is an Imperial star system of the Uridian Sector, centred on the binary Class-F and Class-K type stars, Inaeon Primus and Inaeon Secundus. The Inaeon System is strategically located on the shores of the Western Reaches, deep within the Segmentum Pacificus.

A difficult region to traverse, the Inaeon System has long been a centre of Imperial power projection across the Uridian Isola, and to a limited extent the Whispering Deeps. Nevertheless, numerous Xenoholds have been documented to exist in the Whispering Deeps, among an uncountable number of pirate strongholds and renegade holdfasts.

An ancient star-system, inhabited by Mankind since the height of the Dark Age of Technology, the Inaeon System is littered with the relics of Humanity's bygone epoch, largely making up for its cross-system infrastructure. Most notable of these Dark Age relics is the *Pharus Astropathica*, a great psychic beacon used by the Imperium to bridge the miasma of the Whispering Deeps, and form a solid warp-corridor.

First rediscovered by the Imperium in the 9th Century of the 30th Millennium, the Inaeon System became the first of a series of bridgeheads into the Uridian Isola, quickly being established as a major foothold of Imperial power within the greater Isola. Welcomed by the population of Navaern, the void-hives of Tyrus readily capitulated to the indomitable naval might of the Imperium following a brief sortie in the Gilead Belt. Acting as a staging ground for following Compliance actions across the Uridian Isola, the Inaeon System saw the presence of no less than three Space Marine Legions, and a permanent garrison drawn from at least one.

Though a vital strategic and geo-political asset to the Imperium, the expenditure on its defences has waxed and waned over the prevailing millennia, under the stewardship of the Lightning Sons it has become a stellar fastness; ringed with lines of defensive fortifications and naval choke-points. It stands as one of the most well protected star systems within the greater Uridian Isola, and as of the 42nd Millennium, acts as a vital bridgehead for Imperial forces currently engaged in the Uridian Crusade.

## Notable Worlds

* **Argar (Dead World/Mining World)** - A mining world operated by the Adeptus Mechanicus.
* **Navaern (Civilised World/Space Marine Chapter Homeworld)** - An arid and spare desert world, most of the planets population dwell in the large urban centres spread throughout the planets more temperate, habitable poles. Homeworld to the Lightning Sons Chapter, Navaern is home to their ancient fortress-monastery, the Fortis Luminus. Navaern is guarded by three Ramilies-class Starforts and a PDF of roughly 20 regiments of the Navaernite Templeguard.
	+ **Aegyr (Moon)**
	+ **Luricos (Moon)**
* **Pantona (Agri-World)** - Pantona is an idyllic Agri-World that provides the much needed foodstuffs for the hives and manufactoria of Tyrus. Among the recruitment worlds of the Lightning Sons, a number of notable battle-brothers have come from the verdant fields of Pantona.
* **Tyrus** **(Gas Giant/Hive World)** - Administrative capital of the Inaeon System, the gas giant of Tyrus is one of the greatest ports in the Orelian Sub-Sector and a wonder of its local space. It's billions strong population live out their lives in teaming atmospheric hives, suspended in the gaseous clouds of Tyrus itself, administering to the swaths of ships that pass through the Eagle's Gate.
* **Tharros (Dead World)**
* **Mysost** **(Gas Giant/Mining World)** - Mysost is a distant cousin to Saturn of the Sol system; it's violet bulk surrounded by a ring of asteroids and other astral debris. As such it has become a major mining world for the Imperium and the Adeptus Mechanicus, largely administered to by the latter.
* **Tarkinos (Penal World/Dead World)** - Named for the ancient Navaernite concept of the Underworld, Tarkinos has long served as a Penal World for the systems criminal elements, and administered by the Adeptus Arbites, largely acting as their own headquarters in the system, through which they uphold the tenants of the Lex Imperialis.
* **Rusadir (Dead World/Forbidden World)**
* **Solus (Dead World/Listening Post)** - Solus is a small dwarf planet located in the outer rim of the Inaeon system. Solus is home to the systems early warning system, tasked with keeping a close vigil on the systems Mandeville Points. Though far flung from the civilised heart of the Inaeon system, the importance of Solus cannot be understated. Three regiments of the Tyrean Voidborn are permanently barracked on Solus on a rotational basis.

## Notable Stellar Objects

* **Gilead Belt**
* **Hybos Anchorage** - Imperial Navy picket station and monitoring post located close to the system's ingress Mandeville Point. Destroyed during the early months of the Inaeon War, boarded by mutant hordes and lost to Chaos, and subsequently obliterated by Imperial Navy warships.
