Cosmography: The Calixis sector is fairly large as Imperial sectors go, covering a large and ill-defined swathe of space to the galactic North, rimward of Ixaniad sector and trailing of Scarus sector. To trailing of Calixis sector lies the Fydae Great Cloud (and beyond that the Segmentum Pacificus). To rimward are the wild and partially unexplored regions of the Koronus Expanse that reaches to the edge of the galactic disk and beyond. Sol lies 20.000 light years away and the Eye of Terror only a few thousand - the Astronomicon grows dim and is often partly obscured by the baleful glare of the Eye. Truly Calixis is a distant and lonely place.

History: The region that is now Calixis was only partially surveyed and lightly settled during the Dark Age of Technology. What horrors took place here during the Age of Strife are fortunately long forgotten or mercifully suppressed by the Holy Ordos. The Great Crusade only briefly touched upon the Carlyx expanse and in the millennia that followed the region was largely ignored by the Imperium. That is, up until the Calyx Expanse was re-explored by infamous Rogue Trader Solomon Haarlock 723-736.M36. Haarlock established a personal fief on the world of Solomon, but it was not until 322.M39 and the Angevin crusade that Calixis was brought back into the fold. As such Calixis is a relatively young sector, with only a few worlds that have been continuously inhabited since the Dark Age.

Subsectors: Calixis is divided into a number of sub-sectors and regions. The Golgenna Reach is the civilized heart of the  sector, with the Malfian sub second in importance. The Drusus Marches, the Josian Reach, and the Markayn Marches are second-rate subsectors - important, but not critical to the sector. Adrantis and Hazeroth are subsectors in name only - they are more like autonomous territories if truth be told. Their commercial worth is considered negative (but the Imperium does not abandon its gains and they serves as security buffers for the other subs). The Periphery is not formally a sub-sector.

Golgenna Reach (Scintilla): The central hub of the sector, through which most of the major trade routes pass. Named after Golgenna Angevin, the original commander of the Calyx Crusade (more commonly known as the Angevin Crusade). The most important world is Scintilla, the sector capital. Scintilla is the policical, religious, and commercial hub of Calixis. Scintilla was originally settled during the Dark Age. It was resettled during the Angevin Crusade.

Malfian sub (Malfi): Lying to rimward from the Golgenna Reach the Malfian sub is the most populous subsector of Calixis, both in terms of total Imperial citizens and number of Imperial systems. The Malfian sub guards the rimward borders of the sector and also controls access to the Koronus Expanse and the Halo Stars (the sub-sector fleet is actually stronger than that of the Golgenna Reach; only the main body of Battlefleet Calixis is stronger). The sector capital is Malfi, the most ancient, populous and decadent world in Calixis. There is plenty of friction between Malfi and Scintilla, with Malfi opposing Scintilla in every conceivable (and then some) way.

Drusus Marches (Maccabeus Quintus): This rim/trailing sub lies in the most remote corner of Calixis. It is huge, both in terms of spatial volume and number of settled worlds. It's worlds are typically distant, lightly populated, and lacking in important industries. The sub is big on faith, pilgrims and hardy settlers. The sub-sector capital is the shrine world of Maccabeus Quintus - the local Cardinal-Governor is typically also Lord sub-sector.

Markayn Marches (Solomon): This coreward/spinward sub is centered on the ancient stronghold of the Haarlocks - Solomon. During the Angevin Crusade Solomon became one of the two primary staging grounds for Imperial forces (the other being Sinophia). Solomon was eventually given over to the Departmento Munitorum, with the Haarlocks retaining control only over a remote island. The Haarlocks undoubtedly got something in return. Some trade passes through along secondary routes to Ixaniad and Finial sectors. After the start of the Margin Worlds Crusade Solomon has seen an upsurge in activity, but by and large the Markayn Marches are a remote and unproductive part of the Imperium

Josian Reach (Fenksworld): This coreward sub lies closer to civilized space than any other part of Calixis. The main routes which connect Calixis to Ixaniad (and the Imperium beyond) pass through the Reach by way of Canopus and Fenksworld, generating much revenue. The Josian Reach came into being in M41 as a result of the Meritech Wars - Battlefleet Calixis established a semi-permanent fleet and support facilities to battle the Meritech Clans. After the war it was decided to keep the fleet as a permanent fixture and to support it by removing some territory from the Markayn Marches. Fenksworld remains a major Naval depot to this day and the Josian fleet is the 4th most powerful in Calixis (BF Calixis - Malfi - Glogenna - Josian). The fleet often supports neighboring subs and conduct patrols into Adrantis, Hazeroth and beyond. The Joisan Reach number several productive hives and settled worlds, plus a number of frontier planets. There latter are often settled by Naval veterans and are excellent recruiting grounds for petty officers and armsmen.

Adrantis (Tranch): The Adrantis sub lies trailing of the Golgenna Reach. It is named for the mysterious Adrantis Nebula that lies at the heart of the sub. The worlds of Adrantis are scattered around the nebula, separated by great distances and tenous warp routes. The war-torn world of Tranch is technically sub-sector capital, but in practice the outlying systems fend for themselves or enter into local alliances and trade pacts. The most prominent of these leagues are the so-called 'Far Side League', which comprises Baraspine and several outlying systems. Baraspine's local rival is the Tephaine system with its multiple inhabited planets and moons.

Hazeroth (Clove, Pending approval by Lord Hax): The Hazeroth sub lies corward of Adrantis. It's named after the Hazeroth Abyss, a celestial region even more ill-omened than the Adrantis Nebula. No one ever goes to Hazeroth, not if they have any choice in the matter. The Imperium, however, is as always hell-bent on keeping control over every single piece of stellar property it can get its hands on. The Abyss has remained untamed since the Angevin Crusade and since Lord Hax is a pragmatical man he's not one to waste any resources on this dreary place. The sector capital was originally Guytoga, an Imperial world deep in the Abyss. This proved an...impractical arrangement and the capital was moved to Gunpoint in M40. Gunpoint did not fare well, however, and since mid-M41 Clove has served as de-facto sector capital.

The Periphery (None): This border region stretches for many lightyears towards the Scarus sector. Includes only a handful of worlds, none of them very important. The decaying Imperial world Sinophia should by rights have been made sub-sector capital during the early days of the sector, but political infighting between the Rogue Trader Houses of Haarlock and Sinos effectively sidelined the entire region. The region never received sub-sector status and  consequently no sub capital was named. Trade flows from Calixis to Scarus by way of Sepheris Secundus and Sinophia - but without official recognition the Imperial Governor has limited ability to tax trade passing though his system. Sinophia and the Periphery are actually less well off than they were before the Angevin Crusade.

Threats: Calixis must contend with the usual threats of sedition, treason, heresy, xenos aggression, etc. Calixis biggest challenge is its vast size and nearly endless (both internal and external) borders. Battlefleet Calixis is much too small to effectively defend the sector. The Eye of Terror is not so far away, but there are plenty of other Imperial worlds much closer to the fire. There have been occasional raiders, but nothing major - Calixis is simply too remote. What the Lord Admirals fear is a major xenos incursion, possibly from an as yet undiscovered race...who knows what lurks out there beyond the borders of the Imperium, in the darkness where even the light of the Astronomican fails.
