I am the First, I am the Last
I remember the times before the Heresy, back when the Imperium wasn't as bad as it currently was. I remember having to balance my families favor, and learned that their moods could switch almost instantaneously. Even Father would disregard my brother, when it was him. Sometimes it was me, we both didn't care about who played who.
I remember when my brother's tactics were disregarded by Guilliman, and then after Istvaan III and V, he was forced to change his tone. The very tactics that he had used were his undoing, he was fighting an enemy that his tactics were unable to compensate for.
I remember when the Cabal approached us, and told us of the possible fates of the galaxy. I rejected those answers, as did my brother. We wanted to change the paths before us, fate wasn't set in stone, at least that's what we thought. Our legion joined with Horus, out of necessity.
I remember when we thought it was going to be a battle of good vs evil, like the old stories on Terra, but that was not the case. I remember the Thousand Sons, who had attempted to warn the Emperor of Horus's treachery. While their method was horrid, it had managed to do its job. But the Emperor refused to think that Horus, his most favored son, could ever turn against him.
I remember when the Imperium was, more or less, a whole organization, a well-oiled machine. The bureaucracy was manageable, and the Emperor managed affairs. But now it is a sprawling mess, and nothing short of the Emperor's return could change it.
I remember when Horus was slain, his death sent our forces back. Then, the Imperium launched its counterattack. Wave after wave of soldiers and Space Marines, our lines began to falter. No amount of tactical ingenuity could stand up to unrelenting brute force.
I remember the events on the planet of Eskrador, where my brother faced Guilliman. I was there to see my brother struck down. I remember it infuriated me, that my most thickheaded brother, had slain my twin.
I remember that day, and it remains a permanent mark on my mind. In my grief I had lashed out, and launched a vicious counter-attack, breaking the Ultramarines. While I was unable to slay Guilliman, I managed to scramble his forces, and that satisfied me, for a while.
I remember the millennia that had passed after that incident. My legion began to break down from within, many who used to fight Chaos were now worshiping it. My legion has turned away from its former goal, and now fought Chaos, only in name.
I remember when I decided to take the guise of an Inquisitor, in an attempt to come to terms with my life. I took up the name Kravin, and dedicated myself to the Ordo Malleus. While passing myself off as an Inquisitor, I learned many things, and partook in dangerous actions. But there was one thing I remember I decided to do, and it was giving my twin a record. Admittedly I didn't divulge much, but I sought to give the Imperium knowledge of my twin, and knowledge of what fate had in store for it.
I remember that career lasted for a few decades, before they came to the conclusion that I was an agent of the Alpha Legion. I still find the accusation humorous, for all of their paranoia, they had managed to nearly hit the mark. I than proceeded to leave the order, never to return as an Inquisitor. At least, for the most part.
I remember when Abaddon organized his latest Black Crusade, how could I not. It was but a year ago, and now it stands at Terra's doorstep. I am all alone in my legion, the few who remained uncorrupted are no more, either having been killed, or fallen to Chaos.
I remember when I told myself that I would not meddle in the affairs of the Imperium, in fear of the prophecy I was shown. But then I saw the proverbial writing on the wall. The Imperium was dying, and the Cabal's prediction was correct, but not all was lost for me.
I had set course for Terra, to see it for one last time. Under the guise of an Inquisitor of the Ordos Xenos,. It is here that I realize that mankind has one final chance. I have learned that there is an Exodus fleet, to escape from this galaxy.
I now know that the Cabal's prophecy was misinterpreted, perhaps there was a light at the end of all of this. I now know what must be done, the fleet must escape, and I shall give my life and soul to do so.
With one final glance I look down on Terra, and bid it goodbye. I intend to go with this fleet, to protect it, from whatever threat may arise. I will not reveal my identity just yet, for one doesn't reveal all of their tricks in one hand.
I am Omegon, twin brother of Alpharius. Primarch of the XX Legion, the Alpha Legion. I have stood where others have fallen. I have fought and lived, through trials that have claimed the lives of so many. I will not let my father's Imperium crumble.
That is my vow, to the Imperium, to my deceased brothers, and to Alpharius.
For The Emperor.
