Terra, the birthplace of humanity. I remember its golden cities that stretched across the entire world, that seats and houses our government that is the centre of the Imperium, is home to our great and mighty Emperor who stood tall against the ever-lasting night. The Emperor gave humanity a chance to live among the stairs again, seeing it as our birthright and our next step towards another golden age.
The Emperor knew that once we set foot out in the dark; the creatures, the monsters and the filthy Xenos that lurked in the edges of space would try to consume us, enslave us. He knew humanity would not survive alone in the dark, so he crafted twenty children from his blood that would stand as gods among men and later recognised them as his sons. From this, he created twenty legions of soldiers from their genes, that would stand at the edge of humanity without fear for we know no fear and we deliver vengeance and death towards the enemies of the Imperium.
To fit their new stations among the Imperium, The God Emperor gave them the titles of Primarch of their respective legions to wage a Crusade like none other, to reclaim lost territory and technology that would aid them.
My name is Titerus Vain, I am Lieutenant of the 10th company of the "Sons of Horus", formerly known as The Luna Wolves. I have seen the monsters that wish to devour humanity, I have killed the Xenos that wish to wipe humanity from existence and we were found victorious under the guidance of Warmaster Horus Lupercal and our Primarch.
The Vengeful Spirit, our mighty flagship, takes us through the warp to the Isstvan system to reconquer and to take the system back from these traitors for we go to the capital city of Isstvan III the Choral City.
