The Arx Fidelis and its support fleet made light work of the orbital blockade. One fateful day, iron began to rain down upon the battlefields of Ryboth as the traitor legions fleet was decimated. Finally, the Iron Silence, commanded by Kaurbek, broke orbit. The bombardment stopped. Surface to air fire, stopped. The front fell silent except for the death throes of the Iron Silence. The creeks of steel being superheated echoed over the valleys. The pops of hyper industrial space faring rivets popping under an uncontrollable orbital reentry punched the open air like bolt rounds at an empty range.
"Take cover!" The voices finally shouted as they realised what was transpiring. Retribution had visited Ryboth and now, it was the Iron Warriors who were trapped.
The traitors looked up and watched as their ticket home would be a service forever cancelled. They cared not. They had come for the forges. They had come for resources to fuel their hugger for war. They could repair the Iron Silence. They could rebuild her better than before! Nevertheless, the Iron Warriors had been inconvenienced and the Death Korps of Krieg were an inconvenience standing in the way of their progress. They would need to be exterminated so that the new incoming threat could be mitigated accordingly.
A crackle broadcast over the airwaves of the vox units attached to all traitor Astartes on Ryboth. It was Ferrum Umbra.
"Operation Iron Decimation" he said. "Execute!"
"Sector 1. Received" Chimed the first reply.
"Sector 2 compliant." The second.
"Aye, sector 3." And in short order the orders went down the line to storm the trenches of the Death Korps of Krieg and end the stalemate.
"They will be here soon." Said the Terminator armoured traitor champion.
"Acknowledged." Replied the Tech-Priest of the Dark Mechanicum. His name was Cargore, the hidden consort to Ferrum Umbra.
"Have the forges been primed?" Asked the tusk helmed Terminator champion.
"Affirmative." Replied the spindly dark priest with his synthetically fabricated vox caster. His mechanical fingers, all two dozen of them, danced over a control panel as the green lights of data slates lit up as information was fed to them.
"How long until her maiden walk?" Asked Ferrum Umbra.
"Best estimates indicate a further 200 hours-"
"Not good enough." Slurred the Iron Terminator Champion. "Get it down quicker. We'll need her to greet our guests soon."
Cargore's fingers continued to dance over the data inputs as he struggled to calculate a working solution to the Iron Warriors demand.
"Affirmative." He finally voxed. "Solution established. New estimates, approximately 100 hours." Voxed the dark priest.
"Good." Replied Ferrum Umbra and left the chamber to aid in the extermination of the Death Korps of Krieg.
