Eternal Father

Dromund KaasShortly after the Scouring of Myrkr
The clouds had parted for a particularly festive day on Dromund Kaas, the capital of the Sith Empire. Banners streamed from every parapet, displaying the wicked scarlet crest of the Sith Eternal over a black field. Thousands, tens of thousands even, had flooded the streets of the great Sith capital to attend the execution of the Empire's most hated enemies.
Mandalorians.
The Myrkr campaign had been a success, though it had coincided with a surprise attack at Mandalore that saw the local garrisons withdraw under threat of encirclement by the Mandalorian Union and infection by an outbreak of the Blackwing Virus. While considered a necessary loss, there were many in the Empire's upper hierarchy who chafed at the thought of losing Mandalore to the Mandalorians. So, in retaliation, reprisal raids had occurred up and down the new demarkation lines, and several prominent Mandalorian commanders and clan chiefs taken hostage by the Sith. They had been beaten, deprived of their armor, and paraded before the Sith Citadel to the jeering throngs of Imperial citizens eager and hungry for release. That valve of hate and bitterness had been wound too tightly, and now they found an opportunity to release all that pressure.
Holodroids swarmed the boulevard leading up to the Sith Citadel, capturing every minor detail of the crowd and the assembled condemned as the sun continued to shine through a momentary gap in the dark overcast. Some held their heads high, defiant to the last, while some averted their gaze to the ground while muttering a futile prayer.
One among them stood out, his identity a sensation, his name spoken with revulsion.
Kaine Australis.
The criminal had been captured on Myrkr attempting to flee Sith justice, apprehended by Emperor Carnifex himself, Lady
Taeli Raaf
, and retired Lord Admiral Fiolette Raaf. His stripped body bore the brunt of many scars, the majority of them fresh as he had been subjugated to several beatings prior to this moment. His lips were wound shut by strands of tensile wire, the Sith had no desire to hear him babble empty bravado.

A short speech was delivered by the Emperor, full of rhetoric and hyperbole. It was similar to past speeches delivered by his Supreme Excellency, crafted in such a manner that it inflamed the passions and prejudices of the crowd that had assembled before him. His voice was further broadcasted across the Sith Empire and beyond, for the Sith had no qualms about showcasing their acts of justice to the rest of the galaxy. He finished his speech strong, right hand clenched into a tight fist as he delivered the final prose.
"... And never again will these mongrels profane the galaxy with their very breath, let it be known that it was the Sith who restored peace."
Cheers and applause, so deafening that it could be felt rather than heard across New Kaas City. Basking in the adulation, the Emperor turned his gaze to watch as the first Mandalorian was brought forth. The chosen method of execution was a uniquely crafted electro-guillotine perched above a sharp drop, where the condemned was forced into the contraption face down. Their upper body hung over the empty space, their limbs strapped into place by thick durasteel restraints. Their neck was aligned with the humming energy blade, which slammed down to cleanly sever the head from the neck in a single instance.
The Mandalorian's head tumbled down to the ground, bounced around like a misshapen ball, before rolling to a stop. Blood oozed from the cauterized wound, dripping down onto the ground in a slow steady trickle. A few moments later, the Mandalorian's body followed as the restraints were disengaged simultaneously and the body shunted out onto the ground.
And oh, how the crowd cheered.
The next Mandalorian was moved into position.
And so the executions continued.
