The bigger warrior ran a hand through his hair, frowning as he took in the dismal nature of their surroundings.

'Thank the Emperor,' he said. 'We're not on Medrengard!'

His companion smiled and tilted his head back, letting the cold rain run down his face, as though such a sensation was a rare and precious gift. 'No, Pasanius,' he said, 'we're not.'

'Then where are we?'

'I think we are almost home, my friend,' said Uriel Ventris.

Though it was dusk, Uriel's eyes could easily pierce the gloom enveloping the city once the afterimages of the Omphalos Daemonium's departure or destruction had faded. No trace remained of its passing, and Uriel was grateful to be rid of the vile daemonic creation.

Once it had been the infernal conveyance of a mighty creature of the warp, an engine by which it could traverse the dreadful regions of warp, time and space to wreak havoc on mortals throughout the galaxy. That daemon was gone, destroyed by another of its diabolical kind, allowing Uriel and Pasanius to escape the daemon world of Medrengard in its blood-soaked interior.

'Where do you think it's gone?' asked Pasanius, his hand resting on the butt of a purloined boltgun. Though his right arm was gone below the elbow, Uriel knew that Pasanius was equally adept at killing with his left. Uriel too was armed, a golden-hilted sword that had once belonged to Captain Idaeus, his mentor and former captain of the Fourth Company of the Ultramarines, gripped in one fist.

'I don't know and I don't care,' said Uriel, breathing the crisp air and relishing the fresh, wild scents carried from the forests that circled the mountains towering over them. He saw flocks of grazing beasts on the rugged flanks of the peaks, and the sight of something so unthreatening was absurdly welcome. 'I am just glad we're free of it.'

'Aye, there's that,' agreed Pasanius. 'Now we just have to figure out where it's dumped us. I certainly wasn't steering, were you?'

'No, but I don't think the Omphalos Daemonium was ever meant to be steered by the likes of us.'

'So we could be anywhere,' said Pasanius.

'Indeed,' said Uriel, as curious as his friend to know where they had been deposited. Though he had no idea why the daemon engine had chosen to end their journey upon this world, whichever world it was, he had spent the unknown period of time within its depths visualising Macragge and his home world of Calth, hoping against hope that thoughts of familiar places would somehow guide the mighty engine's course towards them.

It hadn't worked. This world neither looked nor felt like either of those worlds. The sky above was leaden grey, with brooding and dissatisfied clouds scudding around the peaks of the high, craggy mountains that looked down on the strange, abandoned city they found themselves within.

Uriel turned from the mountains to survey their more immediate surroundings, a wide, marble-flagged square choked with rubble and weeds. The buildings around the edge of the square had been cast to ruin by time and, unmistakably, the brutal effects of war. Bullet holes, laser scarring and promethium burns marked almost every inch of stonework and the cold sense of the lingering dead hung heavy in the air.

'So I wonder where this is?' said Pasanius, turning in a circle. 'It's Imperial at least.'

'How do you know that?'

'Look,' said Pasanius, nodding towards the building behind Uriel.

Uriel followed Pasanius's nod to see a double-headed, bronze eagle hanging at a forlorn angle from a tall building of blackened stone. The arched niches and statuary, though broken and in a state of gross disrepair, were unmistakably those of an Imperial temple. The Unfleshed gathered beneath the eagle, their heads craned back to stare in rapt adoration at the symbol of the Emperor.

'Or at least it was an Imperial world,' pointed out Pasanius. 'This place is dead.'

'Aye,' agreed Uriel. 'This place is dead, but there will be others.'

'You sure?' asked Pasanius. 'I hope you're right.'

'I am,' said Uriel. 'I don't know how, but I just am.'

'Another one of your feelings?' said Pasanius. 'Emperor preserve us. That always means trouble.'

'Well, wherever we are, it has to be better than Medrengard.'

'That wouldn't be hard,' pointed out Pasanius. 'I don't know many places that wouldn't be a step up from a world in the Eye of Terror.'

Uriel conceded the point, trying to blot out memories of Medrengard's continent-sized manufactories, its impossible fortresses, the billowing clouds of hot ash that seared the throat with every breath and the vile, dead things that soared upon the thermals of hellish industry.

They had endured all manner of horrors on Medrengard in the service of their Death Oath, but despite everything the home world of the Iron Warriors could throw at them, they had triumphed and escaped.

But where were they?

Uriel's thoughts were interrupted as those of the Unfleshed that could, dropped to their knees before the church of the Emperor. Those with anatomies too twisted to kneel simply bowed their heads, and a low, keening moan issued from their distorted throats. Uriel could only imagine what these poor, pitiful creatures might be feeling.

As if sensing his scrutiny, the largest of the creatures turned to face Uriel and shuffled over towards him, its steps heavy and its sheened body rippling with monstrously powerful muscles. A pungent, animal odour came with the creature, the Lord of the Unfleshed, his body raw and crimson, the soft rain dripping from him in red droplets.

As always, the sight of this creature brought a mix of feelings to the surface: horror, pity, anger and a protective urge to see that they were not treated as their appearance would suggest, for the Lord of the Unfleshed was, by any definition of the word, a monster.

Taller than Uriel, the Lord of the Unfleshed's body was grossly swollen and built beyond the power of a Space Marine. Once, not so long ago, he had been a child, a captive taken by the dreaded Iron Warriors to Medrengard, where daemonic magic and the cruel attentions of the Savage Morticians had wrought him into a freakish beast.

In an attempt to hothouse fresh warriors, the diabolical surgeon-creatures of the Warsmith Honsou had implanted stolen children in grotesque daemonic wombs and fed their developing anatomies a gruel of genetic material concocted from fallen Iron Warriors and captured Astartes gene-seed.

A capricious and unpredictable alchemy at best, this process resulted in far more failures than successes and those pathetic, mutant offspring deemed too withered or degenerate to be further transformed were flushed from the hellish laboratories like so much excrement.

Most such abortions died in Medrengard's nightmarishly polluted wastelands, but some did not, living as skinless monsters driven into the darkest abyss of madness and despair by the horror of their own existence.

Uriel and Pasanius had first seen the Unfleshed, as other inhabitants of Medrengard had dubbed them, as they slaughtered the degenerate prisoners of an Iron Warriors' flesh camp. He had been horrified by their savagery, but later came to realise that they were as much victims of the Iron Warriors as any of those lost souls whose bodies had been tortured beyond all endurance in the camps.

When Uriel had come to realise the truth of the Unfleshed's existence, he had been horrified and filled with pity for these towering monsters, for they were creations of flesh and blood that carried the essence of Space Marine heroes in their veins.

They all boasted physiques reminiscent of carnival grotesques in their unnatural anatomies, with flaps of dead skin pulled over their deformities as if such paltry disguises could hide their warped flesh. One creature's jaw was kept forever open by distended fangs like splintered bone, another was cursed with the withered, still living body of its conjoined twin fused to its chest, another's skeletal structure was so warped that it no longer resembled anything human and moved with a locomotion never before seen in man nor beast.
