The jewel of the Hexaria Imperia isn't its capital world. It is the Iron Cluster. The group of five worlds is in the center of the Lammistrost Sector, which is the territory of the Scarlet Coven, led by Trinty Khaethril, the Unholy. The Iron Cluster is controlled by the Dark Mechanicum Heretek Archmagos Xandros, the Cogitator of Pain. Here is where the deadliest ships of the Imperia and the Chaos infused technology and weapons that fill them are created. The Iron Cluster has long been a part of the Hexaria Imperia. Their bond with the Scarlet Coven has made it the most powerful of the three covens and the only one to never lose its position. This is where the Scarlet Coven Fleet is gathered in combination with the Dark Mechanicum Curse Covenant Fleet. Both fleets have been blessed with the gifts of Grandfather Nurgle, making their ships an unholy combination of flesh and metal that is capable of taking unbelievable amounts of damage. At their heart are the twin flagships Plaguebringer and Poxmonger.
As Fleet Thunderbolt, led by Captain Arc Thane, hits the Coven of the Eternal Abyss in the Zagorn Sector, and Fleet Guardian, led by Dalat, hits the Society of the Horned Host Coven in the Golyra Sector. The dark majesty of the Wrathful Fall burst into the Lammistrost Sector alone, needing no fleet. Swollen with power from feasting on those demons in the Warp, too stupid or too slow to flee from her as she smashed through its hateful corridors, she wasted no time in venting her rage on the nearest enemies to her translation point, which was part of the fleet stationed above Lammistrost III.
All the gifts of Nurgle could not save them from her wrath as she tore into them. Lord Eversight and Dread Supreme Xal Rubros both stand on the bridge, watching as Zhi controls the ship with deft flicks of her hands. The sheer destruction she wrought with each gesture is appreciated by both men on a primal level. They both know the Imperium is a rotting corpse, but they fight for the species and the Emperor's true dream, not the nightmare it has become in his absence. These are enemies of that dream, and thus, they will all feel his wrath.
They take up station over Lammistrost III. Even as Zhi continues to clear its skies, Eversight pulls up a screen and starts scanning the surface. Much of the world's resources have been transported to the ships, but the majority of a Titan Legion remains.
"Well, I think it is time to unleash the Knightmares," says Eversight as he looks at Xal, "What say you, Dread Supreme?"
Xal smiles back at his Lord. If there is a more predatory smile in the galaxy, Eversight has never seen it.
"Wake them from their dreams so they can deliever the final nightmare to this traitor filth, my Lord Eversight."
Eversight sends the command that wakes up the terror-given form that is the Ordo Knightmare. As the first of them opens their burning black eyes, the Warp screams. Eversight delivers doom via drop beam to the surface of Lammistrost IIl. He almost feels sorry for those below. Almost.
