Myrian Septumvirate

The emblem of the Septumvirate.

*This article is a multi-user project, please see the trivia section for a full list of participants and permitted editors.*

The **Myrian Septumvirate** is the name given to an informal alliance held between six Chapters and one loyalist Warband of Adeptus Astartes, formed after the Reclamation of Coele-Myr in early M42. As these Chapters, of differing ages, lineage and temperament, found themselves bonded by conflict and an increasingly tumultuous galaxy, they recognised the need to strengthen bonds of friendship and establish defensive agreements. As the alliance is informal and officially does not exist, each member has agreed to maintain a degree of secrecy about the arrangement, especially as one member is officially labelled as renegade by the administration of the Imperium. While it still retains the moniker of Septumvirate, several additional Chapters have been inducted into their ranks in the years since.

## Formation

During the conflict which occurred in the Coele-Myr Sector of Ultima Segmentum, which spanned the first decade of the 42nd millennium, a number of units of Adeptus Astartes Chapters were drawn into the conflict, including multiple Chapters and a warband from the Blades of Onyx, an ancient taskforce which had been declared renegade despite remaining staunchly loyal to the Imperium. As the conflict developed, these Chapters and the warband found themselves fighting together against the forces of Chaos arrayed against them, for years at a time. Often by the end of a battle, the survivors were operating in mixed formations, such was the nature of the brutal fighting.
The bonds of kinship thus forged remained as the conflict drew to its conclusion. So, when the commander of the Immortals present, Artaxerxes Ishim Hydarnes, suggested that this friendship be cemented in an alliance, most of those present assented to the idea. The commanders of six of the Chapters, including the Immortals, Star Golems, Nemean Lions, Lightning Wraiths, Imperial Wardens and Draconian Impalers gathered, along with the leader of the Warband from the Blades of Onyx.

Together they pledged to come to the aid of each other in the event of a monumental threat to any of the members, and to renew their bonds of friendship through frequent gatherings at one of the Chapter's Homeworlds or Monastery's. They also swore to maintain secrecy over the alliance and in particular the involvement of the Blades of Onyx and their continuing existence from the Imperium as a whole.

## Members

Originally composed of seven members, the alliance has since expanded to include additional new members, brought in by association due to other arrangements or due to participating in conflicts that the Septumvirate has engaged in and being deemed worthy or joining.

**Original Members**
Blades of Onyx

Founding member.

Due to their secretive nature, the Blades were initially reluctant to partake in an alliance that would tie them to the Imperium which officially shuns them. Their concerns were alleviated when the other members agreed that the alliance would remain a secret and that no one would reveal the existence of the Blades.Draconian Impalers

Founding member.Immortals

Founding member.

The alliance was proposed by their leader, Artaxerxes Ishim Hydarnes.Imperial Wardens

Founding member.Lightning Wraiths

Founding member.

The Lightning Wraiths initially were averse to the concept of being in an alliance with multiple chapters given their reclusive nature, despite being in relatively good terms with most of them. However, Hydarnes was able to convince Ilyas Khassim - the most senior Astartes of the Lightning Wraiths present during the Coele-Myr Campaign - to at least consider the tactical advantages of said alliance. The Lightning Wraiths' inclusion to the alliance was cemented during a meeting between Atraxerxes Ishim Hydarnes and Szulah Nuk'Fallad at the aftermath of the Carrhae Campaign.Nemean Lions

Founding member.

The Nemeans were hesitant to agree to the alliance, but were persuaded by Hydarnes and the blessing of Iphaclus.Star Golems

## Joint Conflicts

* **Reclamation of Coele-Myr** - The conflict that spawned the alliance, this was a sprawling conflict that took place in the 42nd millennium between the forces of Chaos and the Imperium of Man. Initially an attempt to awaken a Chaos artefact, the conflict expanded after the opening of the Cicatrix Maledictum drew additional traitor forces and daemons to the bloodletting. Eventually no fewer than eight Chapters of the Adeptus Astartes would be drawn into the defence, along with thousands of regiments of the Astra Militarum.
