There was a huge cavern beyond. Four slender columns rose up in the centre, up and up into the shifting darkness far above. Beneath them fires burned. Many fires, printing white images into Logen's stinging eyes. Coals crackled and cracked and spat out smoke. Sparks came up in stinging showers, steam came up in hissing gouts. Globs of melted iron dripped from crucibles, spattering the ground with glowing embers. Molten metal ran through channels in the floor, striking lines of red and yellow and searing white into the black stone.

The yawning space was full of Shanka, ragged shapes moving through the boiling darkness. They worked at the fires, and the bellows, and the crucibles like men, a score of them, or more. There was a furious din. Hammers clanged, anvils rang, metal clattered, Flatheads squawked and shrieked to each other. Racks stood against the distant walls, dark racks stacked with bright weapons, steel glittering in all the colours of fire and fury.

Logen blinked and stared, head pounding, arm throbbing, the heat pressing onto his face, wondering if he could believe his eyes. Perhaps they had walked into the forge of hell. Perhaps Glustrod had opened a gate beneath the city after all. A gate to the Other Side, and they had passed through it without ever guessing.

He was breathing fast, in ragged gasps, and couldn't make them slow, and every breath he took was full of the sting of smoke and the stink of Shanka. His eyes were bulging, his throat was burning, he could not swallow. He wasn't sure when he had drawn the Maker's sword, but now the orange light flashed and flickered on the bare dark metal, his right hand bunched into a fist around the grip, painful tight. He couldn't make the fingers open. He stared at them, glowing orange and black, pulsing as if they were on fire, veins and tendons starting from the taut skin, knuckles pale with furious pressure.

Not his hand.

'We'll have to go back,' Ferro was saying, pulling at his arm, 'find another way.'

'No.' The voice was harsh as a hammer falling, rough as a whetstone turning, sharp as a drawn blade in his throat.

Not his voice.

'Get behind me,' he managed to whisper, grabbing hold of Ferro's shoulder and dragging himself past her.

There could be no going back now…

… and he could smell them. He tipped his head up and sucked in hot air through his nose. His head was full of the reek of them and that was good. Hatred was a powerful weapon, in the right hands. The Bloody-Nine hated everything. But his oldest-buried, and his deepest-rooted, and his hottest-burning hatred, that was for the Shanka.
