He slid into the cavern, a shadow between the fires, the noise of angry steel echoing around him. A beautiful and familiar song. He swam in it, revelled in it, drank it in. He felt the heavy blade in his hand, power flowing from the cold metal into his hot flesh, from his hot flesh into the cold metal, building and swelling and growing in waves with his surging breath.

The Flatheads had not seen him yet. They were working. Busy with their meaningless tasks. They could not have expected vengeance to find them where they lived, and breathed, and toiled, but they would learn.

The Bloody-Nine loomed up behind one, lifting the Maker's sword high. He smiled as he watched the long shadow stretch out across the bald skull a promise, soon to be fulfilled. The long blade whispered its secret and the Shanka split apart, clean down the middle like a flower opening, blood spraying out warm and comforting, spattering the anvil, and the stone floor, and the Bloody-Nine's face with wet little gifts.

Another saw him now and he came for it, faster and angrier than the boiling steam. It lifted an arm, lurching backwards. Not nearly far enough. The Maker's sword sheared through its elbow, the severed forearm spinning over and over in the air. Before it hit the ground the Bloody-Nine had struck the Shanka's head off on the backswing. Blood sizzled on molten iron, glowed orange on the dull metal of the blade, on the pale skin of his hand, on the harsh stone under his feet, and he beckoned to the others.

'Come,' he whispered. They all were welcome.

They scattered for the racks, seizing their spiked swords, and their sharp axes, and the Bloody-Nine laughed to watch them. Armed or not, their death was a thing already decided. It was written into the cavern in lines of fire and lines of shadow. Now he would write it in lines of blood. They were animals, and less than animals. Their weapons stabbed and cut at him, but the Bloody-Nine was made of fire and darkness and he drifted and slithered between their crude blows, around their fumbling spears, under and over their worthless screams and their useless fury.

Easier to stab the flickering flame. Easier to cut the shifting shadows. Their weakness was an insult to his strength.

'Die!' he roared, and the blade made circles, savage and beautiful, the letter on the metal burning red and leaving bright trails behind. And where the circles passed everything would be made right. The Shanka would scream and gibber, and the pieces of them would scatter, and they would be sliced and divided as neatly as meat on the butcher's block, as dough on the baker's block, as the corn stubble left by the farmer's scythe, all according to a perfect design.

The Bloody-Nine showed his teeth, and smiled to be free, and to see the good work done so well. He saw the flash of a blade and jerked away, felt it leave him a lingering kiss across his side. He knocked a barbed sword from a Flathead's hand, seized it by the scruff of the neck and forced its face down into the channel where the molten steel flowed, furious yellow, and its head hissed and bubbled, shooting out stinking steam.

'Burn!' laughed the Bloody-Nine, and the ruined corpses, and their gaping wounds, and their fallen weapons, and the boiling bright iron laughed with him.

Only the Shanka did not laugh. They knew their hour was come.

The Bloody-Nine watched one jump, springing over an anvil, a club raised to crush his skull. Before he could slash it from the air an arrow slipped into its open mouth and snatched it backwards, dead as mud. The Bloody-Nine frowned. He saw other arrows now, among the corpses. Someone else was spoiling his good work. He would make them pay, later, but something was coming at him from between the four columns.

It was cased all in bright armour sealed with heavy rivets, a round helmet clamped over the top half of its skull, eyes glinting beyond a thin slot. It grunted and snorted, sounds loud as a bull, iron-booted feet thudding on the stone as it thundered forwards, a massive axe in its iron-gloved fists. A giant among Shanka. Or some new thing, made from iron and flesh, down here in the darkness.

Its axe curved in a shining arc and the Bloody-Nine rolled away from it, the heavy blade crashing into the ground and sending out a shower of fragments. It roared at him again, maw opening wide under its slotted visor, a cloud of spit hissing from its hanging mouth. The Bloody-Nine faded back, shifting and dancing with the shifting shadows and the dancing flames.

He fell away, and away, and he let the blows miss him on one side and the other, miss him above his head and beneath his feet. Let them clang into the metal and the stone around him and fill the air with a fury of dust and splinters. He fell back, until the creature began to tire under all that weight of iron.

The Bloody-Nine saw it stumble, and he felt the touch of his moment upon him, and he surged forward, raising the sword above his head, opening his mouth and making a scream that pressed on his arm, and his hand, and the blade and the very walls of the cavern. The great Shanka brought the shaft of its axe up in both fists to block the blow. Good bright steel, born in these hot fires, hard and strong and tough as the Flatheads could forge it.

But the work of the Master Maker would not be denied. The dull blade cleaved through the shaft with a sound like a child screaming and scored a gash a hand deep through the Shanka's heavy armour from its neck down to its groin. Blood splattered out onto the bright metal, onto the dark stone. The Bloody-Nine laughed and dug his fist into the wound, ripping out a handful of the Shanka's guts as it toppled away and crashed onto its back, the neatly severed halves of its axe clattering from its twitching claws.

He smiled upon the others. They lurked there, three of them, weapons in hand, but they would not come on. They lurked in the shadows, but the darkness was no friend to them. It belonged to him, and him alone. The Bloody-Nine took a step forward, and one more, sword hanging from one hand, a length of bloody gut from the other, winding slowly from the slaughtered Flathead's corpse. The creatures shuffled back before him, squeaking and clicking to each other, and the Bloody-Nine laughed in their faces.

The Shanka might be ever so full of mad fury, but even they had to fear him. Everything did. Even the dead, who felt no pain. Even the cold stone, which did not dream. Even the molten iron feared the Bloody-Nine. Even the darkness.

He roared and sprang forward, flinging his handful of entrails away. The point of his sword raked across a Shanka's chest and spun it round, squealing. A moment later and the blade thudded into its shoulder and split it to its breastbone.

The last two turned to run, scrambling across the stone, but fight or run, where was the difference? Another arrow slid into the back of one before it got three strides and it sprawled on its face. The Bloody-Nine darted out and his fingers closed round the ankle of the last, tight as a vice, dragging it towards him, its claws scrabbling at the soot-caked stone.

His fist was the hammer, the floor was the anvil, and the Shanka's head was the metal to be worked. One blow and its nose split open, broken teeth falling. Two and he smashed its cheek-bone in. Three and its jaw burst apart under his knuckles. His fist was made of stone, of steel, of adamant. It was heavy as a falling mountain and blow after blow it crushed the Shanka's thick skull to formless mush.

'Flat . . . head,' hissed the Bloody-Nine, and he laughed, hauling up the ruined body and flinging it away, turning in the air, to crash down into the broken racks. He reeled around, weaving across the chamber, the Maker's sword dangling from his hand, the point striking sparks from the stone as it clattered after him. He glared into the darkness, turning and shifting, but only the fires moved, and the shadows moving around them. The chamber was empty.

'No!' he snarled. 'Where are you?' His legs were weak, they would hardly hold him up any longer. 'Where are you, you fuckers . . .' He stumbled and fell on one knee on the hot stone, gasping in air. There had to be more work. The Bloody-Nine could never do enough. But his strength was fickle, and now it was flowing out of him.

He saw something move, blinked at it. A streak of darkness, sliding slow and quiet between the pulsing fires and the tipping bodies. Not a Shanka. Some other kind of enemy. More subtle and more dangerous. Sooty dark skin in the shade, soft steps padding around the smears of blood his work had left. She had a bow in her hard hands, string pulled back halfway and the bright head of the arrow glinting sharp. Her yellow eyes shone like melted metal, like hot gold, mocking him. 'You safe, pink?' Her voice boomed and whispered in his ringing skull. 'I don't want to kill you, but I will.'

Threats? 'Cunt bitch,' he hissed at her, but his lips were stupid clumsy and nothing came out but a long dribble of spit. He wobbled forward, leaning on the sword, straining to get up, fury burning in him hotter than ever. She would learn. The Bloody-Nine would give her such a lesson that she would never need another. He would cut her in pieces, and grind the pieces under his heels. If he could just get up . . .

He swayed, blinking, breath rasping in and out, slow, slow. The flames dimmed and guttered, the shadows lengthened, blurred, swallowed him up and pushed him down.

One more, just one more. Always one more . . .

But his time was up . . .

. . . Logen coughed, and trembled, shivering weak. His hands took shape in the murk, curled into fists on the dirty stone, bloody as a careless slaughterman's. He guessed what must have happened, and he groaned and felt tears stinging his eyes. Ferro's scarred face loomed at him out of the hot darkness. So he hadn't killed her, at least.

'You hurt?'

He couldn't answer. He didn't know. It felt like there might be a cut on his side, but there was so much blood it was hard to tell. He tried to stand, lurched against an anvil and nearly put his hand in a glowing furnace. He blinked and spat, knees trembling. Searing fires swam before his eyes. There were corpses everywhere, sprawled out shapes on the sooty ground. He looked around, dull-witted, for something to wipe his hands on, but everything was spattered with gore. His stomach heaved, and he stumbled on wobbly legs between the forges towards an archway in the far wall, one bloody hand clamped to his mouth.

He leaned there, against the warm stone, dribbling sour blood and spit onto the ground, pain licking at his side, at his face, at his torn knuckles. But if he'd been hoping for pity, he'd chosen the wrong companion.

'Let's go,' snapped Ferro. 'Come on, pink, up.'

He couldn't have said how long he shambled through the darkness, gasping after Ferro's heels, the sound of his own breath echoing in his skull. They crept through the guts of the earth. Through ancient halls filled with dust and shadows, stone walls riddled with cracks. Through archways into winding tunnels, ceilings of mud propped with rickety beams.

Once they came to a junction and Ferro pressed him back into the darkness by the wall, both of them holding their breath as ragged shapes scraped and shuffled down a hallway that crossed theirs. On and on corridor, cavern, burrow. He could only follow, dragging after her until he knew he would fall on his face at any moment from simple tiredness. Until he was sure that he would never see daylight again . . .

'Wait,' hissed Ferro, putting her hand against his chest to stop him and nearly pushing him over his legs were so weak. A sluggish stream joined the hallway, slow-moving water flapping and rippling in the shadows. Ferro knelt down beside it, peering into the dark tunnel it flowed out of.

'If it joins the river downstream, it must come from outside the city.'

Logen was not so sure. 'What if it . . . comes up from . . . underground?'

'Then we find another way. Or we drown.' Ferro shouldered her bow and slid in, up to her chest, her thin lips pressed tight together. Logen watched her wade out, arms held up above the dark water. Did she never tire? He was so sore and weary he wanted only to lie down and never get up. For a moment he considered doing it. Then Ferro turned and saw him squatting on the bank. 'Come on, pink!' she hissed at him.

Logen sighed. There was never any changing her mind. He heaved one reluctant, trembling leg into the cold water. 'Right behind you,' he muttered. 'Right behind.'

No Good for Each Other Ferro waded on against the current, up to her waist in fastflowing water, teeth gritted against the gripping cold, Ninefingers sloshing and gasping behind her. She could just see an archway up ahead, faint light from beyond glinting on the water. It was blocked with iron bars, but as she forced her way close she could see they were rusted through, thin and flaking. She pressed herself up against them. Beyond she could see the stream flowing down towards her between banks of rock and bare mud. Above was the evening sky, stars just starting to show themselves.

Freedom.

Ferro fumbled at the old iron, air hissing between her teeth, fingers slow and weak from the cold. Ninefingers came up beside her and planted his hands next to hers four hands in a row, two dark and two pale, clamped tight and straining. They were pressed against each other in the narrow space and she heard him grunting with effort, heard the rushing of her own breath, felt the ancient metal beginning to bend, squealing softly.

Far enough for her to slither between.

She pushed her bow, and quiver, and sword through first, holding them up in one hand. She hooked her head between the bars, turning sideways, sucking in her stomach and holding her breath, wriggling her shoulders, then her chest, then her hips through the narrow gap, feeling the rough metal scraping at her skin through her wet clothes.

She dragged herself onto the other side, tossing her weapons onto the bank. She braced her shoulders in the archway and planted her boots against the next bar, every muscle straining while Ninefingers dragged on it from the other side. It gave all of a sudden, snapping in half and showering flakes of rust into the stream, dumping her on her back, over her head in the freezing water.

Ninefingers started to haul himself through, face twisted with effort. Ferro floundered up, gasping with the cold, grabbed him under the arms and started pulling, felt his hands grip round her back. She grunted and wrestled and finally dragged him out. They flopped together onto the muddy bank and lay there, side by side. Ferro stared up at the crumbling walls of the ruined city rising sheer above her in the grey dusk, breathing hard and listening to Ninefingers do the same. She had not expected to get out of that place alive.

But they were not away quite yet.

She rolled and clambered up, dripping wet and trying to stop herself shivering. She wondered if she had ever been so cold in her whole life.

'That's it,' she heard Ninefingers muttering. 'By the fucking dead, that's it. I'm done. I'm not moving another stride.'

Ferro shook her head. 'We need to make some distance while we still have light.' She snatched up her weapons from the dirt.

'You call this light? Are you fucking crazy, woman?'

'You know I am. Let's go, pink.' And she poked him in the ribs with her wet boot.

'Alright, damn it! Alright!' He stumbled reluctantly up, swaying, and she turned, started to walk up the bank through the twilight, away from the walls.

'What did I do?' She turned and looked at him, standing there, wet hair dripping round his face. 'What did I do, back there?'

'You got us through.'

'I meant-'

'You got us through. That's all.' And she slogged off up the bank. After a moment she heard Ninefingers following.

It was so dark, and Logen was so tired, that he barely even saw the ruin until they were almost inside it. It must have been a mill, he reckoned. It was built out right next to the stream, though he guessed the wheel had been missing for a few hundred years or more.

'We'll stop here,' hissed Ferro, ducking through the crumbling doorway. Logen was too tired to do anything but nod and shamble after her. Thin moonlight washed down into the empty shell, picking out the edges of stones, the shapes of old windows, the hard-packed dirt of the ground. He stumbled to the nearest wall and sagged against it, sliding slowly down until his arse hit the mud.

'Still alive,' he mouthed silently, and grinned to himself. A hundred cuts and scrapes and bruises clamoured for attention, but he was still alive. He sat motionless damp and aching and utterly spent, let his eyes close, and enjoyed the feeling of not having to move.

He frowned. There was a strange sound in the darkness, over the trickling of the stream. A tapping, clicking sound. It took him a moment to realise what it was. Ferro's teeth. He dragged his coat off, wincing as he pulled it over his torn elbow, and held it out to her in the dark.

'What's this?'

'A coat.'

'I see it's a coat. What for?'

Damn it but she was stubborn. Logen almost laughed out loud. 'I may not have your eyes, but I can still hear your teeth rattling.' He held the coat out again. 'Wish I had more to offer you, but this is all I've got. You need it more 'n me, and there it is. No shame in that. Take it.'

There was a pause, then he felt it pulled out of his hand, heard her wrapping it round herself. 'Thanks,' she grunted.

He raised his eyebrows, wondering if he could have heard that right. Seemed there was a first time for everything. 'Alright. And to you.'

'Uh?'

'For the help. Under the city, and on the hill with the stones, and up on the roofs, and all the rest.' He thought about it for a moment. 'That's a lot of help. More than I deserve, most likely, but, well, I'm still good and grateful for it.' He waited for her to say something, but nothing came. Only the sound of the stream gurgling under the walls of the building, the sound of the wind hissing through the empty windows, the sound of his own rough breathing. 'You're alright,' he said. 'That's all I'm saying. Whatever you try to make out, you're alright.'

More silence. He could see her outline in the moonlight, sitting near the wall, his coat wrapped round her shoulders, damp hair sticking spiky from her head, perhaps the slightest gleam of a yellow eye, watching him. He cursed to himself under his breath. He was no good at talking, never had been. Probably none of that meant anything to her. Still, at least he'd tried.

'You want to fuck?'

He looked up, mouth hanging open, not sure if he could've heard right. 'Eh?'

'What, pink, you gone deaf on me?'

'Have I what?'

'Alright! Forget it!' She turned away from him, pulling the coat angrily round her hunched shoulders.

'Hold on, though.' He was starting to catch up. 'I mean . . . I just wasn't expecting you to ask is all. I'm not saying no . . . I reckon . . . if you're asking.' He swallowed, his mouth dry. 'Are you asking?'

He saw her head turn back towards him. 'You're not saying no, or you're saying yes?'

'Well, er . . .' He puffed his cheeks out in the dark, tried to make his head work. He'd never thought to be asked that question again in all his days, and least of all by her. Now it had been asked, he was scared to answer. He couldn't deny it was somewhat of a daunting prospect, but it was better to do it, than to live in fear of it. A lot better. 'Yes, then. I think. I mean, of course I am. Why wouldn't I? I'm saying yes.'

'Uh.' He saw the outline of her face frowning down at the ground, thin lips pressed angrily together, like she'd been hoping for a different answer and wasn't quite sure what to do with the one he'd given. He wasn't either, if it came to that. 'How do you want to get it done?' Matter of fact, as if it was a job they had to get through, like cutting a tree down or digging a hole.

'Er . . . well, you'll have to get a bit closer, I reckon. I mean, I hope my cock ain't that disappointing, but it won't reach you over there.' He half smiled, then cursed to himself when she didn't. He knew she wasn't much for jokes.

'Right then.' She came at him so quick and businesslike he half backed off, and that made her falter.

'Sorry,' he said. 'Haven't done this in a while.'

'No.' She squatted down next to him, lifted her arm, paused as if she was wondering what to do with it. 'Nor me.' He felt her fingertips on the back of his hand gentle, cautious. It almost tickled, her touch was so light. Her thumb rubbed at the stump of his middle finger, and he watched her do it, grey shapes moving in the shadows, awkward as a pair who'd never touched another person in their lives. Strange feeling, having a woman so close to him. Brought back all kind of memories.

Logen reached up slowly, feeling like he was about to put his hand in the fire, and touched Ferro's face. It didn't burn. Her skin was smooth and cool, just like anyone's would have been. He pushed his hand into her hair, felt it tickling the webs between his fingers. He found the scar on her forehead with the very tip of his thumb, traced the line of it down her cheek to the corner of her mouth, tugging at her lip, his skin brushing rough against hers.

There was a strange set to her face, he could tell it even in the dark. It was one he wasn't used to seeing on her, but there was no mistaking it. He could feel the muscles tense under her skin, see the moonlight on the cords standing from her scrawny neck. She was scared. She could laugh while she kicked a man in the face, smile at cuts and punches, treat an arrow through her flesh like it was nothing, but it seemed a gentle touch could put the fear in her. Would've seemed pretty strange to Logen, if he hadn't been so damn frightened himself. Frightened and excited all at once.

They started pulling at each other's clothes together, as if someone had given the signal for the charge and they were keen to get it over with. He struggled with the buttons on her shirt in the darkness, hands trembling, chewing at his lip, as clumsy as if he'd had gauntlets on. She had his open before he'd even done one of hers.

'Shit!' he hissed. She slapped his hands away and undid the buttons herself, pulled her shirt off and dropped it beside her. He couldn't see much in the moonlight, only the gleaming of her eyes, the dark outline of her bony shoulders and her bony waist, splashes of faint light between her ribs and the curve underneath one tit, a bit of rough skin round a nipple, maybe.

He felt her pull his belt open, felt her cool fingers sliding into his trousers, felt her- 'Ah! Shit! You don't have to lift me up by it!'

'Alright . . .'

'Ah.'

'Better?'

'Ah.' He dragged at her belt and fumbled it open, dug his hand down inside. Hardly subtle, maybe, but then he'd never been known for subtlety. His fingertips made it more or less into hair before he got his wrist stuck tight. It wouldn't go any further, for all his straining.

'Shit,' he muttered, heard Ferro suck her teeth, felt her shift and grab her trousers with her free hand, dragging them down over her arse. That was better. He slid his hand up her bare thigh. Good thing he still had one middle finger. They have their uses.

They stayed like that for a while, the pair of them kneeling in the dirt, nothing much moving apart from their two hands working back and forward, up and down, in and out, starting slow and gentle and getting quicker, silent except for Ferro's breath hissing through her teeth, Logen's rasping in his throat, the quiet suck and squelch of damp skin moving.

She pushed herself up against him, wriggling out of her trousers, shoving him back up against the wall. He cleared his throat, suddenly hoarse. 'Should I-'

'Ssss.' She got up on one foot and one knee, squatting over him with her legs wide open, spat in one cupped hand and took hold of his cock with it. She muttered something, shifting her weight, easing herself down onto him, grunting softly. 'Urrrr.'

'Ah.' He reached out and pulled her closer, one hand squeezing at the back of her thigh, feeling the muscles bunch and shift as she moved, the other tangled tight in her greasy hair, dragging her head down against his face. His trousers were screwed up tight round his ankles. He tried to kick them off and only got them tangled worse than ever, but he was damned if he was going to ask her to stop just for that.

'Urrrr,' she whispered at him, mouth open, lips sliding warm and soft against his cheek, breath hot and sour in his mouth, her skin rubbing against his, and sticking to it, and peeling away again.
