Once the prophet had come, though, that was the end for the Covenant, at least in the open. We went underground, those of us who understood what things were really about. We gathered what we needed, and stored it away, out of sight. And, such is the way of things, it all became stronger through secrecy. Old words were hissed through locked doors, and we would mouth the ossified canticles under the ostensibly ardent singing of the new ones. They were the best days, if I'm honest, full of promise and guile and silent murders in the dark.
We knew, of course, that He would come soon after that. The prophet kept telling us, and every augur and flesh-sacrifice screamed it out. I wanted to see this Master of Mankind so very much, since I knew more than most what it would mean for the universe. I wanted to witness the creature I was destined to bring low. I wanted to see Him dragged before me like a lowing ox before the sickle knife. I was never, ever taken in by Him, not like so many who afterwards claimed they had somehow been wronged or misled.
I knew, right from the start.
I knew, before He even set foot on my dry-as-bones home world.
I knew all this because I've never aspired to be anything other than what I am - an eavesdropper, a sneak, a fertile soakaway for lies and poison. Judge me if you will, and plenty do, but we all have our places within this far-from-ideal creation.
Here I stand. I can do no other.
First, we had to change. We had to become His warriors. We had to cast our old bodies aside and take on new ones, like caterpillars wriggling out of chrysalises. We went into all this knowing that we were donning blasphemous forms, and that our sacred human shapes would be mangled and pummelled by unbelievers. This was a real sacrifice, despite the gifts we knew we would inherit, and I remember the bitterness of it.
And we were all too old, in truth. Even though our mortal bodies were still on the cusp of hardening into adulthood, we were beyond the optimal age for the transition. As a result it hurt. It hurt like nothing I have felt before or since. Imagine someone plucking your organs out, twisting them inside out, stuffing them back in, filling your veins with acid and cracking your bones. Many of us died. Some of those who perished badly had been steeped in the ways of the Covenant and that was enough to give the rest of us pause - were we really being looked after?
But I made it. Like an unlucky talisman that keeps popping up, I pulled through and found myself, blinking hard and bleeding softly, on the other side. For the first time in my life, once fully recovered, I was strong. Horrifically so. Where I had previously slunk and slithered, now I could strut. I would stand before my collection of mirrors and marvel at this muscle-wrapped god-form. We learned to fight in new ways, and with new weapons. We learned to drill ourselves into that heavy armour and use it to make us faster than malice. There was a seduction there, one that could have been dangerous. I briefly saw the attraction of the entire Imperial project - a universe of purely material extravagance, bound by ancient science and divorced from the messy realm of the spiritual.
Only briefly, of course. For the most part, the spectacle appalled me. I began to take the scripts on my flesh more seriously, and the marks became longer-lasting. I selected passages from our various books that could be read in a number of different ways, pleasing all the various masters that, in those days, we had to please. Only later, when my primarch had taken up his own authorial career and things were becoming straightforward, did I make my facial etchings irreversible, and that was long after the need for ambiguity had dissipated.
There were a thousand subtleties to negotiate. Terrans made up the bulk of the Legion, and they were all drearily atheistic. Even the many Colchisians could not be relied upon, split as they were between the old faith and the new one as well as the jostling creeds of materialism. We were a body of mongrels, desert hermits flung out into a void populated by more variety than we could ever have imagined possible. Those of us who cleaved to the single truth - the deep truth - had to tread with care, taking our time, working slowly into positions of authority and influence
I was in my element. I was not the most powerful warrior in this Legion, nor the most gifted commander, but I was never assailed by any kind of uncertainty. I knew the destination before we had even begun the journey. In a sense I was the destination. I was my treachery, and my treachery was me. There were no choices to make just time to wait out and traps to avoid.
Out in the emptiness of the abyss, all the truths I had encountered in abstract on Colchis were met in concrete. The first time I set foot on a starship, I could smell the empyrean evaporating from its decks. The first time we made for the warp, I almost laughed at the absurdity of the exercise - we were briefly, insubstantially, hurling ourselves through the realm of the Powers themselves, and no one batted an eyelid. The level of self-deception was colossal, and I couldn't see how it would be sustained for
