MedHammer 40,000 Ultramar

Founded in Exile, and refounded during the Ultramari Crusade of M33, the Realm of Ultramar has far exceeded the "500 Realms" of Gulliman's founding and at its height covers much of the South West of the Ultima Segmentum. The region is internally fractious and is covered with squabbling noble princes, Mark II clad spiritual warriors, Religiously blessed pilgrims, and Imperial "Advisory Corps"

Government

The Vigil Opertii

The Intelligence service of the Royum de Ultramar, this ancient organization predates the Creation of the realm, founded by Rouboute Gulliman during his early governance. It was the Vigil Opertii who first alerted Roboute Gulliman of the Betrayal of Calth and disinformation campaign led by Lorgar Pseudaurellian. During the Ultramari reconquest, agents of the Vilgilantes aided the MacCragge government in exile, providing vital information and destabilizing enemy strongholds through sabotage and assasinations. Their time living in the shadows of Luther's demonic reign of Ultramar has hardened and fanaticized the order. It prowls Utramar for threats from Chaos as well as new threats like the T'au and Tyrranids. The Vilgites have both a public and private face, they are well known and respected among all Ultramari forces, but their actual activities are for the most part unknown. Officially, the Vigilites answer to the Counseiller and Collegium, though who answers to who is suspiciously unclear.

Vigil Etranger

One of the most recent creations of the Vigilites, the Xenos order origionally was created for the pseudo-benevolent reason of redirecting Xenos forces to the betterment of Ultramar. However, following the T'au revolt their mission parameters has changed towards containment and extermination of xenos races. It is rumored that they have agents throughout the Segmentum Tempestus, observing Dorn's methods in annihilating the Tyrannids.

Vigil Tamlapan

Essentially the Ordo Malleus from Vanilla, they originated from the "Dark Years" of Chaos controlled Ultramar.

Vigil Gralis

The most secretive institution in Ultramar, these forces exist to protect Ultramar from allies. Their particular targets are The Adeptus Mechanicus, and The Inquisition.

Vigil Ettimengri

The origional and oldest sect of the Vigilites, the Ettimengri focus on internal stability of ultramar. Given that Ultramar lacks a true central authority, they are mostly focused on threats to the Aurelian Cult. Unlike the other two sects, who are known to have a rivalry with each other. Vigil Ettimengri cooperates with both Malleus and Etranger to root out threats to Ultramar. For instance, they work alongside the Tamlapan for rooting out signs of Corruption and Chaos worship, while they aid Etranger with Genestealer Cults and signs of T'au Infiltration.

Imperial Presence

Though the Realm of Ultramar is an "independent ally" of the Imperium by terms of treaty, it is in many ways more closely linked to the Imperium than its rival subject state, the also nominally independent Adeptus Mechanicus. While the Mechanicus is a begrudging servant of the imperium tied by economic and military dependence, the Royum Ultramar is for the most part militarily independent. The Ultramar Realm more closely bound on a cultural, institutional, and religious level than the Mechanicus. The imperium's presence is felt through its joint institutions with Ultramar, particularly the Codex Astartes chapters, who have a outsized presence in the region. Most major systems of Ultramar have some sort of Imperial presence.

Other Imperial Presences

By the 41st Mellenium it was becomming clear to the Imperium that T'au War and Tyrranids were far greater threats than chaos was. As such, Ultramar, being on the forefront of both, has been recieving troops and support from the farthest reaches of the imperium. The Tallarn and Macharian Fleets as well as the Kroot nations have begun to appear with more frequency within ultramar.

Militaries

Ultramar is a heavily decentralized realm, and there are as many militaries as their are planets, nobles, and churches. Though most are negligable, the diversity of Ultramar has led to the rise of some truly exceptional, if not small, forces. These forces are regularlly called by Ultramar to defend against external threats as well as contributions to the Imperial tithes through the Trillieurs.
