A different kind of Knight

Prologue

In a universe where peace has died a long time ago and happiness had ceased
to exist... In the grimdarkness of the 41st millenium. A battle is fought
on a planet whose name is meaningless to the people and filth
who are embroiled in the flames of war. This planet is nothing than
a mere drop compared to the entirety of the empire that it chose to
secede from. We take focus on a fighter from the Imperium of Man. A pilot of a venerable god-machine of war. A relic
from a bygone age, resembling of the knights of yore. This machine, is too
called, a Knight. Equipped with a Vast array of weapons on a body supported by legs that can move in an unbelievably agile speed while also being covered in plates of armor that is nigh indestructible. Its pilot a lone Freeblade sits in the cockpit of the war machine. stock still yet the gargantuan war machine moves with a swiftness that terrifies the enemies that dare to oppose it. The knight dodges blades and bolts effortlessly while he responds againsts the attacks with twice the fury and hate that they tried to kill him with. "Die you filthy xenos! DIE!" The pilot yells as he sinks the chattering teeth of his chainblade sword deep inside of a ramshackled ork construction known as a Mega Dredd. A fiery explosion engulfs the soon-to-be burning hulk of scrap and xenos filth. It falls to the ground while the Knight rises on the battlefield alone. surrounded by xenos. Still, the pilot gave all he got
with his lumbering 12 metere war machine as he desperately yells into the
vox communion for relief. "TO ALL IMPERIAL FORCES! HEED MY CRY FOR REINFORCEMENTS! IN DANGER OF BEING OVERRUN!" Yet no answer came to
respond to his desperate pleas for help. Nobody can deny the end result of
one-sided battle. And so his end came as a unnoticed melta shot bore deep
into the plasma reactor of his once mighty war-machine. The death is quick and
painless as the pilot is instantly melted by the white, hot, and glaringly bright reactor explosion. The xenos around the burning hulk of adamantium and Imperial technology erupt into a racuos roar of victory and jubilation. "WAAAAAAGGGGHHH!"
And so the story of our noble Knight pilot ends here. Or does it?
...
After seeing the HUD flash a warning that the reactor is damaged. A white flash
envelopes me before I could even register the warning in my mind. I guess
this is the end of me. "Your duty isn't done yet." A voice came out of nowhere
even though all I can see feel, taste, or even think is nothing but an empty void. Yet I was still able to hear this mysterious voice. Now, my duty and and loyalty lies with the Emperor of Mankind through and
through. But for some reason I have the urge to fulfill whatever task that this voice shall beset upon me. "Go." Suddenly l was able to feel things again as I Open my eyes and find myself sitting in the familiar sensation of being on the Throne
Mehcanicum. With the memories and sensations of my death still fresh in mind, I swung the Knight around as to scan the environment for hostiles. Yet the enemies that surrounded me before then are nowhere to be seen, and so is the battlefield where I was slain just as I have slain others on. The surroundings is filled with tall trees and open plains instead of ruined cities. the ground is soft and covered With lush grass instead of being turned to mud by the blood of a field of countless corpses of both friend and foe rotting together. The sounds of an intense battle ceased to exist as it was now replaced by the sounds of gentle nature.
