The phoboi are hybrid biot/biological weapons, breeding themselves through billions of virtual generations and then modifying their own design accordingly. The Oubliette has been at war with them for centuries. And when the Moving City does not move, they can smell blood.
Mieli assesses their weaponry. Her countermeasure gogols are tailored to be used against zokus, not likely to do well against the phoboi’s simple chemical brains. So brute force appears to be a more realistic option: q-dots, antimatter, lasers, and – if it comes to that – the remaining strangelet: although she is worried about what the latter would do to Mars itself.
All right, Mieli says. The plan is simple. You slow them down. I go get the thief. You pick us up. Just like last time.
Understood, the ship says. Be careful.
You always say that, Mieli says. Even when you are about to drop me on a dying city.
I mean it every time, the ship says. Then it wraps Mieli in a q-dot bubble, grabs her with an EM field and fires her at Mars.
Metacortex fully active, Mieli steers with her wings, aiming towards one of the Persistent Avenue agoras. She fires nano-missiles at the city at a considerable fraction of c. She wears armour and carries an external weapon this time, a Sobornost multipurpose cannon – a sleek cylinder full of destruction. The missiles send back fragmented imagery before evaporating: the gevulot system is not fast enough to stop them from transmitting. Her metacortex pieces them together into a coherent picture of the city below.
Bloody faces, stains on white uniforms. Gogol pirates with their upload tendrils out, attacking anything that moves. Young and old Martians locked in battle, wielding makeshift weapons. Military Quiet, cordoning off streets. Tzaddikim, fighting Quiet and humans both, blocking gunfire with utility fog shields. The zoku colony under a q-dot bubble, surrounded by particularly heavy fighting. There, in the centre of the Maze, a black needle that was not there before. And almost directly below her-
The Gentleman is fighting in the Place of Lost Time, harried by a flock of assault Quiet. Her foglet shapes crackle under heavy fire.
Mieli takes the Quiet out with autonomous missiles with a quark-gluon plasma payload. They sweep half the square in an arc of nova-bright flame, illuminating the invisible foglet shapes momentarily: they look like exotic coral, blooming out from the Gentleman.
Phoboi report? Mieli asks Perhonen. The ship shares its senses with her. It is dancing above the seething mass, lobbing microton AM warheads at the phoboi. The sky of the city blinks in synchrony with them, like impossibly bright lightning flashes; the booms follow seconds later.
Not good, the ship says. We really need a viral weapon of some kind. I’m slowing them down, but pincer number two is going to hit the city any minute now.
Mieli slows the descent with her wings but still hits the ground hard. Stone cracks beneath her q-armoured feet. As she gets up from the small crater, she sees Raymonde. A cloud of foglet blades hovers around her, ready to strike.
‘Which one are you?’ she asks. ‘Mieli or the other one?’
‘The one who tells you that you are going to have a phoboi problem in a few minutes,’ Mieli says.
‘Oh, hell,’ Raymonde mutters.
Mieli looks around at the destruction. There is more gunfire down the Avenue, and a distant explosion. ‘Is this supposed to be a revolution?’
‘It went bad an hour ago,’ Raymonde says. ‘The cryptarch-controlled started executing everyone who had the co-memory infection, and then they brought in the military Quiet as well from the ramparts. We have been arming the survivors. As long as the resurrection system survives, we can bring everybody back. But at the moment we are losing. And the real problem is that.’ She points at the needle above the Maze.
‘What is it?’
‘That’s what Jean made,’ Raymonde says. ‘He is inside. With the cryptarch.’
‘The phoboi are coming,’ Mieli says. ‘We need to get this under control now or you are all going to find out what permanent death feels like. You need to get the city moving again. I take it the zoku is not doing anything?’
‘No,’ Raymonde says. ‘I can’t reach them anymore.’
‘Typical,’ Mieli says. ‘All right. You need to get inside that thing, get the cryptarch out and make him stop the fighting so we can deal with the phoboi. I am coming to get the thief out. So it looks like we are going to the same direction.’
Mieli spreads her wings. The tzaddik takes to the air next to her. They fly over the burning city, towards the black needle.
‘You were the ones who disrupted things,’ Isidore says. ‘You have to help us. We are going to have a civil war unless the cryptarch is stopped. The tzaddikim cannot do it alone.’
‘No. Our first loyalty is to ourselves. We have healed; we are strong again. It is time for us to go.’ Around them, the treasure chamber is almost empty: only the silver portals remain.
‘You are running away,’ Isidore says.
‘Merely optimising the use of resources,’ the Eldest says. ‘You are free to come with us, although you will find that your current form will not be appropriate.’
‘I’m staying here,’ Isidore says. ‘This is my home.’
A part of the Eldest’s shimmer forms a miniature city. The streets are full of tiny people. There are flashes of light and flames. Isidore sees the conflict between the cryptarch-controlled and the memory-inoculated. He tastes blood and realises he is biting his tongue. And near the ramparts, white waves, crashing against them, lapping at the legs of the city. Phoboi.
‘You may wish to reconsider your decision,’ the Eldest says.
Isidore closes his eyes. It is a shape that is different from a mystery, rapidly changing, shifting, not static like a snowflake that can be examined from different angles and understood.
‘The cryptarchs,’ he says. ‘The cryptarchs could still end this. They could get the city moving again, stop the fighting. Raymonde thought they were going to go there, with the thief-’ He points at the needle in the miniature city, sticking up like an arrow in its heart.
‘The ring,’ he says. ‘The thief stole my entanglement ring. Pixil, that ghost thing you did, would it work inside that?’
‘Maybe, depending on what that is,’ Pixil says. ‘We just need a Realmgate to find out.’ She starts towards the nearest silver arc.
‘The zoku will not allow this,’ the Eldest says.
‘Just get me through it,’ Isidore says. ‘That’s all I ask. I can’t just stand here and watch.’
Pixil touches the zoku jewel at the base of her throat. She squeezes her eyes shut. For a moment, her face twists in pain. The jewel comes off, like a small creature being born. She holds it up with bloody fingers. ‘The freedom we always have left,’ she says, ‘is the freedom to leave. I’m out. I was born here. I’m staying.’
She takes Isidore’s hand. ‘Let’s go.’
‘What are you doing?’ the Eldest says.
Pixil touches the gate. Honey-coloured daylight pours out. ‘The right thing,’ she says. Then she steps through, pulling Isidore in after her.
