Cawlen Hurq raised his rifle and Nisato wanted to laugh at the absurdity of fighting beasts of such terrible appearance with so paltry a weapon. The man screamed an oath as he opened fire, bright bolts of energy spitting from the barrel to explode harmlessly on the creature's chest.

Casually, as though swatting an irritant, the beast batted Cawlen Hurq across the room. The man slammed head first into the beaten iron bar top and even over the sound of tearing metal and screaming crowds, Daron Nisato heard his neck snap with an awful, brittle crack.

Nisato tried to drag Mesira away from the ripped open entrance to the bar, but she released his hand and he was carried away from her, watching helplessly as the monsters tore their way inside the bar.

'It is time,' she said, her voice sounding like a clear bell in his head, 'time to die.'

Uriel heard the screams and the sound of tearing metal. The rumble of the trio of Chimeras echoed from the ramshackle walls of the street and curious onlookers were beginning to spill from their homes to see what drama was being played out on their doorstep.

From his vantage point in the commander's hatch, Uriel could see light spilling into the sky and could hear screams that were issued in terror of the monstrous. Whatever bloody task the Unfleshed were about was in full swing by the sounds of it.

A smashed building on the corner of the street provided another sign as to the passing of the Unfleshed and the Chimera's driver expertly guided the heavy vehicle around the cascaded tumble of timber, stone and steel.

Beyond the corner, the street widened out into a stone-paved square, and the few onlookers that had been driven into the street by the noise, sensibly retreated into their homes at the sight that greeted them.

'Guilliman's oath!' swore Uriel as he saw the spectacle before him.

It looked like a brightly lit pyramid of wrecked tanks, their innards hollowed out and reshaped by hammer and welding torch to form a structure with internal spaces, rooms, corridors and low-ceilinged chambers. Light and people spilled from the shuddering building, its structure and fabric under siege by the Unfleshed.

The Lord of the Unfleshed led the attack, his massively muscled arms peeling back steel as he forced his way into the structure. Myriad neon lights spat fat sparks and bathed the square before the building, surely some kind of drinking den, as well as the monsters in lurid greens, shocking pinks and deathly blues. They capered and howled as the leader of their tribe smashed a path through steel and timber like an animal breaking open a nest to devour the prey within. If the Lord of the Unfleshed was aware of their arrival, he gave no sign, but continued with his destruction of the building's frontage.

Fleeing people were snatched up by the Unfleshed and snapped and twisted until they broke, and their agonised screams ceased. Uriel heard gunfire from inside the building and wondered what the Lord of the Unfleshed could want in a place like this.

The Chimeras slowed as they entered the square, but Uriel yelled down to the driver. 'No! More speed. Use the vehicle!'

Understanding Uriel's order, the driver opened up the throttle and the Chimera roared as its speed increased. Uriel braced himself as one of the Unfleshed turned at the sound of the madly revving engine, its face seeming to split in two, such was the width of its fanged jaws.

Its skeleton was visible through the sickly, pallid skin that draped it, yet this new covering could only hope to cover a portion of its malformed anatomy. Long limbs, spidery and clawed, dragged on the ground and short, muscular legs drove it forwards with an ape-like gait.

Beast and machine charged towards one another until they met in a howl of flesh and machinery. The Chimera ploughed into the creature, its understanding of the power and momentum of the tank existing only for the fraction of a second before it was crushed beneath the tracks. Liquid light spurted from its pulverised carcass, blood, meat and bone ground to a paste on the paved square.

The vehicle skidded on the square as the driver instinctively feathered the throttle and applied the brakes. The engine revved one last time and died, mushrooming clouds of stinking, acrid smoke belching from the exhausts as the driver fought to restart the engine.

'Pasanius! With me!' shouted Uriel, pulling himself up from the commander's hatch. He vaulted to the hard ground as the assault door on the back of the vehicle opened and Pasanius led the warriors out onto the strangely lit battlefield.

Uriel's other two Chimeras screamed to a halt on either side of his and the warriors disembarked with practiced efficiency. No matter the losses they had taken and no matter what they may have done in the past, these men and women were soldiers first and foremost, and had learned their lessons well.

They formed up in squads and Uriel felt a forgotten sense of pride at the idea of leading men into battle once more. No matter that these soldiers were not Ultramarines of the Fourth Company, they were warriors of the Emperor and that made them mighty.

'Together! We finish this together! Are you with me?' yelled Uriel, holding his golden-hilted sword up for all to see.

The soldiers unsheathed their falcatas and roared their affirmation as Uriel turned and charged towards the devastated bar.

The monster's thick, veined arm reached into the bar, questing for Mesira. She seemed to welcome the creature's attentions, for she ignored Daron Nisato's shouted pleas to flee from it and make her way through the mob towards him.

Blinded by panic, many of the bar's patrons stumbled into the path of the enormous creature. The lucky ones blundered past it into the night and safety, the less fortunate were torn to fleshy rags or bitten in two.

The press of the crowd was preventing Mesira from approaching the monster any closer, for it seemed that such was her goal. The terrifying creature was utterly fixated upon her, only prevented from reaching her by what strength remained in the collapsed frontage of the bar. For once, Nisato had cause to be thankful that this part of Junktown was comprised of the debris of his old regiment, for it was all that was preventing the creature from gaining access.

Had the bar been constructed from traditional building materials, the beast would even now be feasting on Mesira's bones and wrapping her entrails around its neck. Only the steel girders and beams looted from abandoned tanks had thus far prevented it from simply bludgeoning its way inside and devouring her and everyone else inside.

The structure of the bar groaned and heaved as load bearing members were smashed asunder. Metal ground on metal as lintels were compressed and weight was redistributed to portions of the structure never meant to carry such loads.

The gunmen that the late Cawlen Hurq had placed in the bar fired on the monster with their pistols, emptying magazines' worth of rounds to little or no effect. Where punctured by a bullet, the beast dribbled light and a syrupy ichor, but such wounds troubled it not at all.

The monster howled in frustration, a searing, hungry light roasting in the gouges of its eye sockets. Daron Nisato was paralysed by his fear of it, seeing a primal hunger and anger such as he could barely contemplate existing in any sane universe.

'What in the name of the warp is it?' cried Pascal Blaise, shouting to be heard over the din of the creature's assault on the building.

'I have no idea,' said Nisato. 'We have to reach Mesira and get out of here!'

'You think?' snapped Pascal Blaise, looking in every direction for a means of escape. The press of bodies was too tight and the settling of the structure had wedged many of the doors fast in their frames. Grunting men heaved their shoulders against them, but no amount of human force could overcome the incredible weight keeping the doors shut.
