Crusade… Hero… Saviour… Destroyer.

She smiled and erased the words with a swipe of an elegantly manicured nail, the edge smooth down to the fractal level, and began to write with pronounced, cursive sweeps of the quill.

It is with great heart and a solemn sense of honour that I, Petronella Vivar, Palatina Majoria of House Carpinus do pen these words. For many a long year I have journeyed from Terra, enduring many travails and inconveniences…

Petronella frowned and quickly erased the words she had written, angry at having copied the unnatural affect-edness that so infuriated her in the remembrancers' scripts that had been sent back from the leading edge of the Great Crusade.

Sindermann's texts in particular irritated her, though of late they had become few and far between. Dion Phraster produced some passable symphonies - nothing that would enjoy more than a day or so of favour in the Terran ballrooms - but pleasing enough; and the landscapes of Keland Roget were certainly vibrant, but possessed a hyperbole of brush stroke that she felt was unwarranted.

Ignace Karkasy had written some passable poems, but they painted a picture of the Crusade she often thought unflattering to such a wondrous undertaking (especially Blood Through Misunderstanding) and she often asked herself why the Warmaster allowed him to pen such words. She wondered if perhaps the subtexts of the poetry went over his head, and then laughed at the thought that anything could get past one such as Horus.

She sat back on her chair and placed the quill in the Lethe-well as a sudden, treacherous doubt gnawed at her. She was so critical of the other remembrancers, but had yet to test her own mettle amongst them.

Could she do any better? Could she meet with the greatest hero of the age - a god some called him, although that was a ridiculous, outmoded concept these days - and achieve what they had, in her opinion, singularly failed to do? Who was she to believe that her paltry skill could do justice to the mighty tales the Warmaster was forging, hot on the anvil of battle?

Then she remembered her lineage and her posture straightened. Was she not of House Carpinus, finest and most influential of the noble houses in Terran aristocracy? Had not House Carpinus chronicled the rise of the Emperor and his domain throughout the Wars of Unification, watching it grow from a planet-spanning empire to one that was even now reaching from one side of the galaxy to the other to reclaim mankind's lost realm?

As though seeking further reassurance, Petronella opened a flat blotting folder with a monogrammed leather cover and slid a sheaf of papers from inside it. At the top of the pile was a pict image of a fair-haired Astartes in burnished plate, kneeling before a group of his peers as one of them presented a long, trailing parchment to him. Petronella knew that these were called ''oaths of moment'', vows sworn by warriors before battle to pledge their skill and devotion to the coming fight. An intertwined ''EK'' device in the corner of the pict identified it as one of Euphrati Keeler's images, and though she was loath to give any of the remembrancers credit, this piece was simply wondrous.

Smiling, she slid the pict to one side, to reveal a piece of heavy grain cartridge paper beneath. The paper bore the familiar double-headed eagle watermark, representing the union of the Mechanicum of Mars and the Emperor, and the script was written in the short, angular strokes of the Sigillite's hand, the quick pen strokes and half-finished letters speaking of a man writing in a hurry. The upward slant to the tails of the high letters indicated that he had a great deal on his mind, though why that should be so, now that the Emperor had returned to Terra, she did not know.

She smiled as she studied the letter for what must have been the hundredth time since she had left the port at Gyptus, knowing that it represented the highest honour accorded to her family.

A shiver of anticipation travelled along her spine as she heard far distant klaxons, and a distorted automated voice, coming from the gold-rimmed speakers in the corridor outside her suite, declared that her vessel had entered high anchor around the planet.

She had arrived.

Petronella pulled a silver sash beside the escritoire and, barely a moment later, the door chime rang and she smiled, knowing without turning that only Maggard would have answered her summons so quickly. Though he never uttered a word in her presence - nor ever would, thanks to the surgery she'd had the family chaperones administer - she always knew when he was near by the agitated jitter of her mnemo-quill as it reacted to the cold steel bite of his mind.

She spun around in her deeply cushioned chair and said, 'Open.'

The door swung smoothly open and she let the moment hang as Maggard waited for permission to stand in her presence.

'I give you leave to enter,' she said and watched as her dour bodyguard of twenty years smoothly crossed the threshold into her frescoed suite of gold and scarlet. His every move was controlled and tight, as though his entire body - from the hard, sculpted muscles of his legs, to his wide, powerful shoulders - was in tension.

He moved to the side as the door shut behind him, his dancing, golden eyes sweeping the vaulted, filigreed ceiling and the adjacent anterooms in a variety of spectra for anything suspect. He kept one hand on the smooth grip of his pistol, the other on the grip of his gold-bladed Kirlian rapier. His bare arms bore the faint scars of augmetic surgery, pale lines across his dark skin, as did the tissue around his eyes where house chirurgeons had replaced them with expensive biometric spectral enhancers to enable him better to protect the scion of House Carpinus.

Clad in gold armour of flexing, ridged iands and silver mail, Maggard nodded in unsmiling acknowledgement that all was clear, though Petronella could have told him that without all his fussing. But since his life was forfeit should anything untoward befall her, she supposed she could understand his caution.

'Where is Babeth?' asked Petronella, slipping the Sigillite's letter back into the blotter and lifting the mnemo-quill from the Lethe-well. She placed the nib on the dataslate and cleared her mind, allowing Maggard's thoughts to shape the words his throat could not, frowning as she read what appeared.

'She has no business being asleep,' said Petronella. 'Wake her. I am to be presented to the mightiest hero of the Great Crusade and I'm not going before him looking as though I've just come from some stupid pilgrim riot on Terra. Fetch her and have her bring the velveteen gown, the crimson one with the high collars. I'll expect her within five minutes.'

Maggard nodded and withdrew from her presence, but not before she felt the delicious thrill of excitement as the mnemo-quill twitched in her grip and scratched a last few words on the dataslate.

…ing bitch…

In one of the ancient tongues of Terra its name meant ''Day of Wrath'' and Jonah Aruken knew that the name was well deserved. Rearing up before him like some ancient god of a forgotten time, the Dies Irae stood as a vast monument to war and destruction, its armoured head staring proudly over the assembled ground crew that milled around it like worshippers.

The Imperator-class Titan represented the pinnacle of the Mechanicum's skill and knowledge, the culmination of millennia of war and military technology. The Titan had no purpose other than to destroy, and had been designed with all the natural affinity for the business of killing that mankind possessed. Like some colossal armoured giant of steel, the Titan stood forty-three metres tall on crenellated bastion legs, each one capable of mounting a full company of soldiers and their associated supporting troops.
