Ozymandias

Outer Rim
900 ABY
The world turned as it had a million years before, as the sun rose and set on its horizons and its people rose to work or fell to sleep. Under the enlightened freedom and protection offered to them by the Mandalorian Protectors, it had found a new prosperity unchained by the imperial yoke. Thereupon a world who knew peace parsed sparingly by the militarized imperials yet fighting for control, people lived lives capable of joy.
It was there, in the morning sky over New Junction, that a storm began to form. Lightning arced miles, and dread began to fill the sky as an artificial eclipse shadowed the Capital in violence. Above their heads, and citizens and soldiers alike turned their gaze to the sky and a new dawn - they would see the silhouette of a great harbinger of death. It formed from the aether, a ship out of nightmares forged from the screaming violent deaths of millions; and its name was the on lips of all.
“Mors Mon.”, the Mountain in the Sky, Death’s Chariot.
Amidst shuttering and violent clouds that began to stir the air and form tornados in its wake, it began to ignite the world in an instant, brutal artillery barrage on everything beneath it. So instant was its destruction, thousands of lives turned to ash in only a matter of seconds - ignited tibanna gas cutting great swathes of death through the world. Death on a mass scale had come for this world, marked by the sudden release of five battlecruisers - Khan class destroyers setting out to destroy the various cities of the world.
It became immediately obvious, a fact so brutal there was no denial, that the Sith had not come here for conquest. Their shots didn’t target the military stations with priority, they did not surgically strike at the most important, critical locations, instead saturating the most heavily populated places in seconds. Emergency beacons, SOS signals, a thousand alarms silenced by the brutal and unequal aggression.
Now the world was under siege by a force unwilling to conquer, but to genocide and destroy. This was not the fight most had become used to - wherein they would fight for geopolitical dominance, but the blind and judased destruction of an entire world.

Objective II - Nurgle’s Embrace
Streets ran red with the blood of innocents, tens of thousands, many hundreds quickly falling to the orbital bombardments, bombings, and assaults. These in themselves were destructive and consistent alone, but the assault persisted beyond the realm of conventional arms - as the dead began to rise and attack once more. As it had on Yavin, Felucia, and a dozen worlds before;
The Plague had come to Feriae Junction.
In the streets, riots began to take hold as local police units were quickly overwhelmed. Citizens ran from the carnage, from their loved ones turned infected, to the arms of soldiers and police units incapable of defending them.
Destroy the lives that remain as they funnel into corridors filled with death, or keep as many of the citizens alive as their world comes unfurled.
