Mandavi Sector
The Mandavi Sector is a Region of Imperial space in the Segmentum Ultima. It lies to galactic west of the reestablished Realm of Ultramar along the old trade routes to Segmentum Tempestus. It lies to the south of the Ork Empire of Charadon, although the persistent Warp storm known in Imperial records as 4E696E65 makes Ork incursions rare. It consists of four Sub-Sectors, including Sub-Sector Mandavi,and the usual mix of inter-sector systems and wilderness space.

It was settled during M36 as part of a broader colonization effort. This effort was spearheaded by Regiments of the Astra Militarum being retired following the internecine conflicts of the Age of Apostasy. Three of these Regiments were led by Colonel Sawa Levan, Colonel Mikhail Hamdan and Colonel Char Conditta; who would each give their names to one of the Sector’s Sub-Sectors. Likewise the Mandavi Sector, Mandavi Sub-Sector, and Mandavi System would all take their name from Colonel Piter Mandavi.

In M37, an Ork Waaagh originating in Charadon maneuvered around the western edge of Warp storm 4E696E65 and assaulted the Conditta Sub-Sector. Thanks to the actions of an Ecclesiarchical Priest named Amyntikós, later Saint Amyntikós, the Waaagh was stalled upon the edge of the Sub-Sector until Astartes forces could arrive. Saint Amyntikós was martyred upon the Sub-Sector’s world of Keter, which would later be named his Shrine World.

In M39, the Sector would receive a reprieve from a threatened Ork Waaagh, only to then face the treason of an entire Space Marines Chapter in what would come to be known as The Blue Hand Heresy. The Sector’s Battlefleet and Imperial Guard saw major defections to the traitors and suffer further losses in suppressing the Heresy. While the Guard would rebuild itself under the leadership of the War World of Heb, Battlefleet Mandavi would never fully recover from its losses. In M40, Heb would emerge as one of the major military worlds in the southern central region of the Segmentum Ultima, famed for its Zealous Light Foot Regiments of the Imperial Guard.

Following the 13th Black Crusade and the advent of the Cicatrix Maledictum, the Sector would face a major Ork Waaagh which would be repelled primarily by the Heb and their Mechanicus allies. Once the Heb and Battlefleet Mandavi had secured the Mandavi Sector, it would become one of the few stable regions of Imperial rule between Catachan and Ultramar during the dark and chaotic first century of M42.
