Mechanicum

Fortis Metallum's upper body swivelled around on its gimbal waist mount to face Maven, and though he couldn't see his preceptor's face through the red visor of the cockpit, he could feel the stern, unflinching gaze through the softly glowing slits.

'Keep an eye on our rear in case any slipped past us,' ordered Stator, his voice once again as grim and inflexible as the posture of his machine. 'I'll hold you responsible if they have.'

'Yes, preceptor,' replied Maven. 'I'm on it.'

It was a Martian truism that if a warrior and machine spent enough time linked together they would begin to take on aspects of the other's character. Fortis Metallum was an old machine, cantankerous, flinty and utterly without mercy.

It was the perfect match for Stator.

Maven had met countless Titan drivers and it was easy to tell which machines they commanded within moments of talking to them.

Warhound drivers were belligerent, wolf-like daredevils, whereas the men who fought from the towering Battle Titans were arrogant and ego-driven warriors, who often appeared to hold those around them in contempt.

Maven knew that such conceit was forgivable, for marching to war so high above the battlefield and unleashing such awesome destructive power would naturally swell a man's ego, but it was also a necessary defence against the engine's character overwhelming that of its commander.

Maven walked his machine backwards in a bravura display of skill, watching as Stator turned away to follow Cronus through the mangled remains of the security fencing.

A Knight was much smaller than a Titan, but the mechanics in its construction and operation were no less incredible. A Titan had a crew to maintain its systems: a servitor to man each weapon system, a steersman to drive it, a tech-priest to minister to its bellicose heart, a moderati to run the crew and a princeps to command it.

A Knight was the perfect meld of flesh and steel, a mighty war machine at the command of a single pilot, a warrior who had the confidence to wield its power and the humility to know that, despite that power, he was not invincible.

Maven strode back towards the reactor complex, spreading his auspex net wide to pick up any of the feral servitors that might have broken away from the main pack, though he suspected he would not find any. Even if he did, what threat did a few servitors represent?

Broken and irreparably damaged servitors or those whose cranial surgery had failed to take were often simply dumped in the pallidus, the name given to the toxic, ashen hinterlands that existed between the Martian forges. The vast majority died, but some survived, though to call their doomed existence life was overstating the reality of it.

Most simply attempted to carry out the task for which they had been created, marching back and forth through the wastelands with their fried brains unable to comprehend that they were no longer in service.

In some cases, the damage to their brains allowed them a fragile degree of autonomy and those unfortunate creatures survived by feasting on the dead. Drawn by warmth and power, many banded together in unthinking packs and infested Mechanicum facilities, attacking workers and draining current to sustain their wretched experience.

Such creatures required culling, which brought Maven's thoughts full circle.

He lifted his head, the motion of the Knight's cranial carapace following exactly. The crags around the reactor were empty and desolate, the red volcanic peaks scoured by dust clouds blown up by the high winds funnelled along the northern fossae.

The heart of the reactor facility sat six hundred metres back from the fencing that surrounded it, a collection of intricate buildings of pipes, cables and crackling antenna towers. A huge, domed structure sat in the middle of the complex, its surface studded with plugs and vents. The air rippled around the building and intense waves of heat and electromagnetism washed from it in tidal surges.

The trench of the Gigas Fossae was dotted with several fusion reactors, but the facility upon the rocky slopes surrounding the northern impact crater of Ulysses Patera was the largest, and had been built by Magos Ipluvien Maximal.

Adept Maximal was one of the most senior magi of Mars, and his fusion reactors supplied power to a great many vassal forges dotted around the Tharsis uplands. Such arrangements were common across the red planet, ancient treaties binding the clans and forges together in reciprocal pacts of protection and supply that allowed such varied groups with conflicting needs to coexist. As well as allied forges. Maximal had exchanged bonds of fealty and supply with a number of warrior orders, including many of the most revered Titan Legios.

'So why aren't they here?' Maven muttered to himself. 'Too busy arguing amongst themselves is why.'
