Sebastian Kahler

**Sebastian Kahler** is the Feldmarschall of the 1st Corps of the Obsidian Guard Legion.

## **Background**

Sebastian Kahler was a childhood friend of Lukas before the war that saw Feuerstadt united and the arrival of the Emperor. It was never in question that Sebastian would become an Astartes, among the first to ascend from the Legion’s new homeworld. In the fires of war that forged the Feuerreich Kahler’s legend grew and he rose through the ranks rapidly. By the time the campaign had ended and the Emperor departed he was Feldmarschall of the 1st Corps, a position that he would hold for the rest of the Crusade. Kahler is a firebrand, ever to the fore beside his men, urging them forward with a mixture of encouragement and threats of extra duty shifts. Under Kahler’s command the First Household became renowned for their efficiency throughout the Imperium as Siege Masters without equal, even amongst their brothers and cousins. The defining battle of Kahler’s career was the Altara Crusade, a campaign fought against the forces of Craftworld Altara and its Exodite Allies. Systematically the sector was cleansed of the Aeldari on Kahler’s orders until only the final bastion remained, the Craftworld itself. In a decisive void battle the fleet protecting Altara was destroyed, leaving her vulnerable to the coming storm of Assault Rams that carried Kahler and his men into the heart of the vessel. Not one xeno survived the slaughter. After days of heavy fighting the Astartes retreated, leaving Cyclonic Charges behind and then detonating then after exiting the blast radius.

While always a capable and loyal commander Sebastian Kahler had ever been in his gene-sire’s shadow. That changed after the Vanishing, as with so many other things that had seemed like constants. Lukas’s attention was increasingly diverted by political machinations and grander strategic concerns leaving command of the legion to Sebastian. In the absence of the Primarch Sebastian truly came into his own, rising to the challenge of leading his brothers into battle. It was he who oversaw the Obsidian Guard’s campaigns to crush the anti-Imperial revolts that had erupted after the Vanishing. His methods were brutally pragmatic, upon arriving at each rebellious world he gave them a simple ultimatum: lay down their arms and surrender their leaders to face justice or be wiped out utterly. One world disbelieved either Sebastian’s willingness or ability to carry out his threat and remained defiant in the face of it. Until shells the size of hab blocks fell to the surface like rain. The world in question, Loshankya, was razed to the bedrock so that nothing remained. Once word spread of Loshankya’s fate no other planet refused the offer of clemency. In fact several had already gift wrapped the ringleaders of the rebellions for the Obsidian Guard, eager to show their reaffirmed loyalty and consequently avoid meeting the same fiery end as the people of Loshankya.

When the Obsidian Guard were assigned the unenviable task of containing the Orks of Ullanor for five years, Lukas appointed Sebastian as administrator of the Feuerreich and his envoy to those Forge Worlds open to joining forces with the Obsidian Guard to curb the power of Mars. Due to the publicity surrounding his feud with Kelbor-Hal Lukas often had to act through intermediaries and his preferred candidate was always Sebastian. In these positions of enhanced authority and responsibility he flourished.

## **Personality**

Sebastian was at times both a counterbalancing factor to Lukas and also fed into his worst urges but either way he remained a close confidant to the Primarch.
