Loken lowered his guard completely. The Warmaster?'

'He wants you in. Told me to tell you that himself. He appreciated your work. He admired your sense of honour. "Tarik," he said to me, "if anyone's going to take Sejanus's place, it should be Loken." That's what he said.’

'Did he?'

'No.’

Loken looked up. Torgaddon was coming at him with his axe high and whirling. Loken ducked, side-stepped, and thumped the butt of his tabar's haft into Torgad-don's side, causing Torgaddon to mis-step and stumble.

Torgaddon exploded in laughter. 'Yes! Yes, he did. Terra, you're too easy, Garvi. Too easy. The look on your face!'

Loken smiled thinly. Torgaddon looked at the axe in his hand, and then tossed it aside, as if suddenly bored with the whole thing. It landed with a clatter in the shadows off the mat.

'So what do you say?' Torgaddon asked. ЛУЪа! do I tell them? Are you in?'

'Sir, it would be the finest honour of my life.’ Loken said.

Torgaddon nodded and smiled. Yes, it would.’ he said, 'and here's your first lesson. You call me Tarik.’

IT WAS SAID that the iterators were selected via a process even more rigorous and scrupulous than the induction mechanisms of the Astartes. 'One man in a thousand might become a Legion warrior.’ so the sentiment went, 'but only one in a hundred thousand is fit to be an iterator.’

Loken could believe that. A prospective Astartes had to be sturdy, fit, genetically receptive, and ripe for enhancement. A chassis of meat and bone upon which a warrior could be built.

But to be an iterator, a person had to have certain rare gifts that belied enhancement. Insight, articulacy, political genius, keen intelligence. The latter could be boosted, either digitally or pharmaceutically, of course, and a mind could be tutored in history, ethic-politics and rhetoric. A person could be taught what to think,

and how to express that line of thought, but he couldn't be taught how to think.

Loken loved to watch the iterators at work. On occasions, he had delayed the withdrawal of his company so that he could follow their functionaries around conquered cities and watch as they addressed the crowds. It was like watching the sun come out across a field of wheat.

Kyril Sindermann was the finest iterator Loken had ever seen. Sindermann held the post of primary iterator in the 63rd Expedition, and was responsible for the shaping of the message. He had, it was well known, a deep and intimate friendship with the Warmaster, as well as the expedition master and the senior equerries. And his name was known by the Emperor himself.

Sindermann was finishing a briefing in the School of Iterators when Loken strayed into the audience hall, a long vault set deep in the belly of the Vengeful Spirit. Two thousand men and women, each dressed in the simple, beige robes of their office, sat in the banks of tiered seating, rapt by his every word.

To sum up, for I've been speaking far too long.’ Sindermann was saying, 'this recent episode allows us to observe genuine blood and sinew beneath the wordy skin of our philosophy. The truth we convey is the truth, because we say it is the truth. Is that enough?'

He shrugged.

'I don't believe so. "My truth is better than your truth" is a school-yard squabble, not the basis of a culture. "I am right, so you are wrong" is a syllogism that collapses as soon as one applies any of a number of fundamental ethical tools. I am right, ergo, you are wrong. We can't construct a constitution on that, and we cannot, should not, will not be persuaded to iterate on its basis. It would make us what?'

He looked out across his audience. A number of hands were raised.

There?'

'Liars.’

Sindermann smiled. His words were being amplified by the array of vox mics set around his podium, and his face magnified by picter onto the hololithic wall behind him. On the wall, his smile was three metres wide.

'I was thinking bullies, or demagogues, Memed, but "liars" is apt. In fact, it cuts deeper than my suggestions. Well done. Liars. That is the one thing we iterators can never allow ourselves to become.’

Sindermann took a sip of water before continuing. Loken, at the back of the hall, sat down in an empty seat. Sindermann was a tall man, tall for a non-Astartes at any rate, proudly upright, spare, his patrician head crowned by fine white hair. His eyebrows were black, like the chevron markings on a Luna Wolf shoulder plate. He had a commanding presence, but it was his voice that really mattered. Pitched deep, rounded, mellow, compassionate, it was the vocal tone that got every iterator candidate selected. A soft, delicious, clean voice that communicated reason and sincerity and trust. It was a voice worth searching through one hundred thousand people to find.

Truth and lies.’ Sindermann continued. Truth and lies. I'm on my hobby-horse now, you realise? Your supper will be delayed.’

A ripple of amusement washed across the hall.

'Great actions have shaped our society.’ Sindermann said. The greatest of these, physically, has been the Emperor's formal and complete unification of Terra, the outward sequel to which, this Great Crusade, we are now engaged upon. But the greatest, intellectually, has been our casting off of that heavy mantle called religion. Religion damned our species for thousands of years, from the lowest superstition to the highest conclaves of spiritual faith. It drove us to madness, to war,

to murder, it hung upon us like a disease, like a shackle ball. I'll tell you what religion was... No, you tell me. You, there?'

'Ignorance, sir.’

Thank you, Khanna. Ignorance. Since the earliest times, our species has striven to understand the workings of the cosmos, and where that understanding has failed, or fallen short, we have filled in the gaps, plastered over the discrepancies, with blind faith. Why does the sun go round the sky? I don't know, so I will attribute it to the efforts of a sun god with a golden chariot. Why do people die? I can't say, but I will choose to believe it is the murky business of a reaper who carries souls to some afterworld.’

His audience laughed. Sindermann got down off his podium and walked to the front steps of the stage, beyond the range of the vox mics. Though he dropped his voice low, its trained pitch, that practiced tool of all iterators, carried his words with perfect clarity, unen-hanced, throughout the chamber.

'Religious faith. Belief in daemons, belief in spirits, belief in an afterlife and all the other trappings of a preternatural existence, simply existed to make us all more comfortable and content in the face of a measureless cosmos. They were sops, bolsters for the soul, crutches for the intellect, prayers and lucky charms to help us through the darkness. But we have witnessed the cosmos now, my friends. We have passed amongst it. We have learned and understood the fabric of reality. We have seen the stars from behind, and found they have no clockwork mechanisms, no golden chariots carrying them abroad. We have realised there is no need for god, or any gods, and by extension no use any longer for daemons or devils or spirits. The greatest thing mankind ever did was to reinvent itself as a secular culture.’

His audience applauded this wholeheartedly. There were a few cheers of approval. Iterators were not simply schooled in the art of public speaking. They were trained in both sides of the business. Seeded amongst a crowd, iterators could whip it into enthusiasm with a few well-timed responses, or equally turn a rabble against the speaker. Iterators often mingled with audiences to bolster the effectiveness of the colleague actually speaking.

Sindermann turned away, as if finished, and then swung back again as the clapping petered out, his voice even softer and even more penetrating. 'But what of faith? Faith has a quality, even when religion has gone. We still need to believe in something, don't we? Here it is. The true purpose of mankind is to bear the torch of truth aloft and shine it, even into the darkest places. To share our forensic, unforgiving, liberating understanding with the dimmest reaches of the cosmos. To emancipate those shackled in ignorance. To free ourselves and others from false gods, and take our place at the apex of sentient life. That... that is what we may pour faith into. That is what we can harness our boundless faith to.’
