Karka's Sun

Karka's Sun is a star system in the Vlaktes Mare, named for the venerable red giant star at its heart, it's light blazing at the spinward edge of the Alenic Belt in the Lotharian Marches. It is a lynchpin system in that reach of the sector, a seam of noctilith-rich planets which, throughout the sector's history, have been coveted by a number of factions.

History
Founded in late M38 previo by Ybram Karka, an illegitimate scion of the Bruder Trade Dynasty, Karka's Sun quickly became a focal point for fresh colonization and expansion of the Alenic Belt.

Mechanicus presence in the system has always been heavy, their ancient rites of compact with sector governance on Tectonia Prime entitling them to possession of any sufficiently noctilith-heavy worlds. While the most noctilith-rich world in the system, Oxidia, is under direct control of the Mechanicus, this is not the case for every world (reference the Karkason Trade Wars of M39).

Strangely, the millennia have not been kind to the worlds further spinward from Karka's Sun, with the Mare encroaching and devouring them at a rate directly proportional to the rapidity with which the Mechanicus removed blackstone from the Karkan worlds--though the techpriests flatly deny any correlation between these phenomena.

After the loss of Tectonia Prime, and the severing of the Vlaktes Sector from the wider Imperium, the importance of Karka's Sun and its mineral wealth increased tenfold. Shipments of noctilith from Oxidia became crucial to fashioning psychic channel-caskets for the sector's astropathica synod and psykana cabal, and more mundane resources from Karkason--regolith minerals, steel, and flesh--were all tithed to support the wars of the new Tectonian front.

It was during this period of upheaval, in 11 post KCM.M41, that a combined dynastic tomb fleet of the Necrons appeared in-system, and laid siege to the worlds of Karka's Sun, bringing with them nothing but death.
