Eternal Father
For several days, they'd been unable to contact Coruscant.
Or anyone, for that matter.
Some sort of interference was jamming all inbound and outbound transmissions, but no one could discern if it was a natural phenomenon of the Deep Core or if something artificial was responsible. No trade traffic had arrived in that period, and any ship they sent out of system to investigate never returned. Eventually, they stopped sending out ships and pulled all military vessels in tight around Byss, forming a reinforced cordon around the entire planet.
Tensions were growing, nerves fraying, as another day passed by and then another after that. It seemed as though they were truly, terribly, alone. Some had already given themselves to despair, while others clung onto the savage hope that not all was as it appeared to be.
That there would be somebody, anybody.
Then...
A signal, realspace reversion. Three craft. Star Destroyer class. They appeared out of the gloom, the infamous wedge-shape of the Galactic Empire's foremost ship-of-the-line. Damage left deep pockmarks across their hull, partially patched up with lattices of midnight black metal. One had lost a deflector bulb, another had its underbelly slit open from nearly prow to stern. All of them had evidently seen combat, and were limping back to the Empire's furthest redoubt in the Deep Core.
The lead ship hailed the defense flotilla, deep azure light filling the command deck as the face of none other than Emperor Solipsis swam up before them. All fell to one knee in supplication, bowing in deep reverence to their holy Emperor. He explained to them that the Empire had beaten back an attempted incursion on Coruscant, but that to do so they had to disable communication to the Deep Core. The defenders of Byss rejoiced, confident that their Emperor had seen to another victory.
Clearance codes bearing the Emperor's seal were transmitted, proving the legitimacy of the three ships. The Byss defense fleet parted to let the Emperor and his ships through, their guard lowered further than its ever been in weeks, perhaps months.
They were unprepared when new signals were detected, hundreds of them, no...
Thousands of them.
From the void came multiple fleets, reverting into realspace right on top of the Byss defense fleet and opening fire. Some ships had been in the process of firing from the moment they started reverting from hyperspace, the opening salvo striking several Imperial ships in mere nano-seconds as the enemy appeared. What they had failed to notice was the cloaked binary beacon the lead star destroyer, the one that apparently carried the Emperor, had been broadcasting on a hidden frequency. A beacon that allowed an innumerable number of warships, galleys, and planetary landers to hyperspace jump right amidst the defense fleet.
Chief among the arriving ships was the Eternal Rule, the nominal flagship of the Kainate. Powerful autocannons pivoted in their mountings, bracketing enemy ships with harrowing volleys of cannon fire. A hole had been punched straight through the center of the defense fleet, and now hundreds and hundreds of landers and shuttles streaked down through the gap. A full assault on the Imperial Control Sector began, with Kainate forces landing at virtually all points of interest. Kainate starfighters, powered as much by the Dark Side as by conventional technology, strafed the airways about the continent-spanning city.
The true target was Solipsis' Citadel at the center of the city, and it was where the bulk of Kainate forces had been concentrated. Shuttles and landers disgorged Immortal Legionnaires, Blackblades, and strand-cast Sith across the landing platform adjacent to the Citadel's great hall. Sovereign Protectors, Imperial Sentinels, and members of the Dark Side Elite rushed forward to repel the invaders, and fighting quickly grew desperate and vicious.
Emerging from one of the landed shuttles was Darth Carnifex, Eternal Father of the Kainate. At His side was Darth Prazutis, Mortarch of the Kainate. Together they were the Dark Dyarchy, the ruling power and architects of the Kainate. That they had both come together displayed the importance of this assault, and also the supreme power now weighed against the defenders of Solipsis' rotten Empire, an Empire collapsing all around then with the Fall of Coruscant to the Sith Covenant.
They may have been the first to make landfall, but they would not be the last. The Empire and fallen and all that remained was to pick its corpse clean.
