The ancestors dropped away, sliding back down the pyramid as fast as they had climbed it, leaving Teppic alone on a few square feet of rock.
A couple of stars came out.
He saw white shapes below as the ancestors hurried away on some private errand of their own, lurching at a surprising speed towards the broad band of the river.
The gods abandoned their interest in Dios, this strange little human with the stick and the cracked voice. The nearest god, a crocodile-headed thing, jerked on to the plaza before the pyramid, squinted up at Teppic, and reached out towards him. Teppic fumbled for a knife, wondering what sort was appropriate for gods .
And, along the Djel, the pyramids began to flare their meagre store of hoarded time.
Priests and ancestors fled as the ground began to shake. Even the gods looked bewildered.
IIb snatched his father's arm and dragged him away.
'Come on!' he yelled into his ear. 'We can't be around here when it goes off! Otherwise you'll be put to bed on a coathanger!'
Around them several other pyramids struck their flares, thin and reedy affairs that were barely visible in the afterglow.
'Dad! I said we've got to go!'
Ptaclusp was dragged backwards across the flagstones, still staring at the hulking outline of the Great Pyramid.
'There's someone still there, look,' he said, and pointed to a figure alone on the plaza.
IIb peered into the gloom.
'It's only Dios, the high priest,' he said. 'I expect he's got some plan in mind, best not to meddle in the affairs of priests, now will you come on.'
The crocodile-headed god turned its snout back and forth, trying to focus on Teppic without the advantage of binocular vision. This close, its body was slightly transparent, as though someone had sketched in all the lines and got bored before it was time to do the shading. It trod on a small tomb, crushing it to powder.
A hand like a cluster of canoes with claws on hovered over Teppic. The pyramid trembled and the stone under his feet felt warm, but it resolutely forbore from any signs of wanting to flare.
The hand descended. Teppic sank on one knee and, out of desperation, raised the knife over his head in both hands.
The light glinted for a moment off the tip of the blade and then the Great Pyramid flared.
It did it in absolute silence to begin with, sending up a spire of eye-torturing flame that turned the whole kingdom into a criss-cross of black shadow and white light, a flame that might have turned any watchers not just into a pillar of salt but into a complete condiment set of their choice. It exploded like an unwound dandelion, silent as starlight, searing as a supernova.
Only after it had been bathing the necropolis in its impossible brilliance for several seconds did the sound come, and it was sound that winds itself up through the bones, creeps into every cell of the body, and tries with some success to turn them inside out. It was too loud to be called noise. There is sound so loud that it prevents itself from being heard, and this was that kind of sound.
Eventually it condescended to drop out of the cosmic scale and became, simply, the loudest noise anyone hearing it had ever experienced.
The noise stopped, filling the air with the dark metallic clang of sudden silence. The light went out, lancing the night with blue and purple afterimages. It was not the silence and darkness of conclusion but of pause, like the moment of equilibrium when a thrown ball runs out of acceleration but has yet to have gravity drawn to its attention and, for a brief moment, thinks that the worst is over.
This time it was heralded by a shrill whistling out of the clear sky and a swirl in the air that became a glow, became a flame, became a flare that sizzled downwards into the pyramid, punching into the mass of black marble. Fingers of lightning crackled out and grounded on the lesser tombs around it, so that serpents of white fire burned their way from pyramid to pyramid across the necropolis and the air filled with the stink of burning stone.
In the middle of the firestorm the Great Pyramid appeared to lift up a few inches, on a beam of incandescence, and turn through ninety degrees. This was almost certainly the special type of optical illusion which can take place even though noone is actually looking at it.
And then, with deceptive slowness and considerable dignity, it exploded.
It was almost too crass a word. What it did was this: it came apart ponderously into building-sized chunks which drifted gently away from one another, flying serenely out and over the necropolis. Several of them struck other pyramids, badly damaging them in a lazy, unselfconscious way, and then bounded on in silence until they ploughed to a halt behind a small mountain of rubble.
Only then did the boom come. It went on for quite along time.
Grey dust rolled over the kingdom.
Ptaclusp dragged himself upright and groped ahead, gingerly, until he walked into someone. He shuddered when he thought about the kind of people he'd seen walking around lately, but thought didn't come easily because something appeared to have hit him on the head recently .
'Is that you, lad?' he ventured.
'Is that you, dad?'
'Yes,' said Ptaclusp.
'It's me, dad.'
'I'm glad it's you, son.'
'Can you see anything?'
'No. It's all mist and fog.'
'Thank the gods for that, I thought it was me.'
'It is you, isn't it? You said.'
'Yes, dad.'
'Is your brother all right?'
'I've got him safe in my pocket, dad.'
'Good. So long as nothing's happened to him.'
They inched forward, clambering over lumps of masonry they could barely see.
'Something exploded, dad,' said IIb, slowly. 'I think it was the pyramid.'
Ptaclusp rubbed the top of his head, where two tons of flying rock had come within a sixteenth of an inch of fitting him for one of his own pyramids. 'It was that dodgy cement we bought from Merco the Ephebian, I expect-'
'I think this was a bit worse than a moody lintel, dad,' said IIb. 'In fact, I think it was a lot worse.'
'It looked a bit wossname, a bit on the sandy side-'
'I think you should find somewhere to sit down, dad,' said IIb, as kindly as possible. 'Here's Two-Ay. Hang on to him.'
