'Well, you ain't in Mott any more, Crump. And you ain't Jamber Bole either. You're Crump, and you better get used to it.'

A voice from behind Bottle: 'Did he say Mott Irregulars?'

Bottle turned, nodded at Strings. 'Aye, Sergeant.'

'Gods below, who recruited him?'

Shrugging, Bottle studied Strings for a moment. Koryk and Tarr had carried him to just within the nave's entrance, and the sergeant was leaning against a flanking pillar, the wounded leg stretched out in front of him, his face pale. 'I better get to that-'

'No point, Bottle – the walls are going to explode – you can feel the heat, even from this damned pillar. It's amazing there's air in here…' His voice fell away, and Bottle saw his sergeant frown, then lay both hands palm-down on the tiles. 'Huh.'

'What is it?'

'Cool air, coming up from between the tiles.'

Crypts? Cellars? But that would be dead air down there.. 'I'll be back in a moment, Sergeant,' he said, turning and heading towards the cracked altar. A pool of water steamed just beyond. He could feel that wind, now, the currents rising up from the floor. Halting, he settled down onto his hands and knees.

And sent his senses downward, seeking life-sparks.

Down, through layers of tight-packed rubble, then, movement in the darkness, the flicker of life. Panicked, clambering down, ever down, the rush of air sweeping past slick fur – rats. Fleeing rats.

Fleeing. Where? His senses danced out, through the rubble beneath, brushing creature after creature. Darkness, sighing streams of air.

Smells, echoes, damp stone…

'Everyone!' Bottle shouted, rising. 'We need to break through this floor! Whatever you can find – we need to bash through!'

They looked at him as if he'd gone mad.

'We dig down! This city – it's built on ruins! We need to find a way down – through them – damn you all – that air is coming from somewhere!'

'And what are we?' Cord demanded. 'Ants?'

'There's rats, below – I looked through their eyes – I saw! Caverns, caves – passages!'

'You did what?' Cord advanced on him.

'Hold it, Cord!' Strings said, twisting round where he sat. 'Listen to him. Bottle – can you follow one of those rats? Can you control one?'

Bottle nodded. 'But there are foundation stones, under this temple – we need to get through-'

'How?' Cuttle demanded. 'We just got rid of all our munitions!'

Hellian cuffed one of her soldiers. 'You, Brethless! Still got that cracker?'

Every sapper in the chamber suddenly closed in on the soldier named Brethless. He stared about in panic, then pulled out a wedge-shaped copper-sheathed spike.

'Back off him!' Strings shouted. 'Everyone. Everyone but Cuttle.

Cuttle, you can do this, right? No mistakes.'

'None at all,' Cuttle said, gingerly taking the spike from Brethless's hand. 'Who's still got a sword? Anything hard and big enough to break these tiles-'

'I do.' The man who spoke was the rebel warrior. 'Or, I did – it's over there.' He pointed.

The scimitar went into the hands of Tulip, who battered the tiles in a frenzy that had inset precious stones flying everywhere, until a rough angular hole had been chopped into the floor.

'Good enough, back off, Tulip. Everybody, get as close to the outer walls as you can and cover your faces, your eyes, your ears-'

'How many hands you think each of us has got?' Hellian demanded.

Laughter.

Corabb Bhilan Thenu'alas stared at them all as if they'd lost their minds.

A reverberating crack shuddered through the temple, and dust drifted down. Bottle looked up with all the others to see tongues of fire reaching down through a fissure in the dome, which had begun sagging.

'Cuttle-'

'I see it. Pray this cracker don't bring it all down on us.'

He set the spike. 'Bottle, which way you want it pointing?'

'Towards the altar side. There's a space, two maybe three arm-lengths down.'

'Three? Gods below. Well, we'll see.'

The outer walls were oven-hot, sharp cracking sounds filling the air as the massive temple began settling. They could hear the grate of foundation stones sliding beneath shifting pressures. The heat was building.

'Six and counting!' Cuttle shouted, scrambling away.

Five… four… three…

The cracker detonated in a deadly hail of stone-chips and tile shards.
