Badab Primaris

Badab Primaris, formally known as Badab II, is a former Hive World that was located in the Badab Sector of the Segmentum Ultima. In 718.M1, a failed coup attempt on the Hive World of Badab Primaris led to an abortive civil war, and the Astral Claws Space Marine Chapter stepped in and brutally crushed the conflict. Chapter Master Lufgt Huron personally took matters into his own hands, swiftly reimposing order once more. Taking upon himself the mantle of planetary ruler, Lufgt Huron stylised himself the 'Tyrant of Badab', claiming the inhabited worlds in proximity to the hospitable region of the void around the Badab System as his Chapter's fiefdom. After further requests to redistribute resources from the Maelstorm Zone are denied and met with increased quota demands from the Administratum, in protest, Huron withholds Badab Primaris' planetary tithe to the Administratum and further blocked the passage of trade through his realms in protest over the Adepta's failure to provide him and his allies sufficient resources to police the Maelstrom. Refusing the Astral Claws' role as defenders of the Maelstrom Zone, the Tyrant soon diverted the industrial resources and manpower to directly supplement the Badab Sector's defences as well as augmenting the Maelstrom fleet detachment and fortification of key worlds under his command. The Tyrant ordered the demolition of the ancient citadel of the ruling dominars and instead erected the legendary, hugely fortified 'Palace of Thorns' to his own specifications and design. The clashing entitlement of the Administratum's Imperial tithe and the ancient rights of the Astartes commanders to defend the Imperium by any means necessary swiftly came to be known as the Badab Schism and would last for more than a century and a half, finally culminating in the internecine conflict known as the Badab War.

The final assault on Badab Primaris, the seat of Huron's power, commenced in early 913.M41 and resulted in the final defeat of the Astral Claws. Lufgt Huron eventually fell during the final assault for the Palace of Thorns, although whether he survived or was truly slain remained shrouded in mystery, as his body was borne away by his closest followers. Taking matters into their own hands the savage Carcharodons Chapter sabotaged the vast and ancient atomic and geo-thermal reactors which powered the hives and fed the hungry planetary defence batteries with energy. Beneath the hives of Badab Primaris, the cascading destruction of the deep-sunk reactor cores took its toll. Tectonic shocks and volcanic eruptions destroyed the surface of the planet, and the majority of the planet's population was exterminated within a few standard days.
