'Wamphyri?' Harry guessed.

'Oh, yes. You'd better come over here.'

Go over there? Harry believed he knew why: to be away from the gate. He knew the voice, too. He didn't know it - couldn't possibly know it - but he knew it. He moved to obey, and the flying shapes came closer.

The two leading shapes, Shaithis aboard a flyer, and a riderless warrior, swooped down out of the sky. They began to circle, and Shaithis's beast sank lower, the wind of its great wings blasting dust and grit up from the plain into Harry's and the Dweller's faces. Its shadow fell on them as it shut out the stars, and Shaithis's booming voice called:

'Surrender! Surrender now, to the Lord Shaithis!'

'Are you ready, father?' said The Dweller. He held up one wing of his cloak.

Harry believed. No, he knew. The child he had searched for was eight years old, and this young man was at least twenty, but the two were one and the same. How didn't matter, not right now. Harry's whole world, his entire life, had been filled with things just as strange as this. Stranger.

'I'm ready, son,' he answered, his voice catching a little. 'But... does it work here?'

'Oh, it works. Except you mustn't use it too close to a Gate.'

'I know,' said Harry. 'I tried it once.'

Shaithis settled his beast to earth to the west, his warrior crunched down to the east. Other shapes loomed in the sky, almost directly overhead. 'Ho, Dweller,' Shaithis called, dismounting. 'It seems I have you!'

'Let me take you to our garden,' said Harry Jnr to his father.

Harry stepped forward, took him in his arms and hugged him. He felt his son's cloak close around him.

Shaithis, striding forward, jerked to a halt. Dust leaped up from the plain, formed itself into a devil that swirled in the vacuum that the two men had left behind. They were no longer there.

For long moments Shaithis stood, his flattened, convoluted snout sniffing the air. Then his great nostrils flared and his eyes blazed their fury. He threw back his head and roared. And as the plain echoed his cry, so he began to curse. And then he made his vow:

'Dweller, I shall have you!' he snarled. 'You and your garden and all you possess. I shall have your magic, your weapons, your cloak of invisibility, your every secret. Do you hear? I shall have you, and the hell-landers, and everything. And when I have these things, then I shall use them to make myself the most powerful Lord there ever has been or ever will be. So speaks Shaithis of the Wamphyri. So let it be!'

The echoes of his cry, his cursing and his vow died away, and for a long time Shaithis stood there alone with his dark Wamphyri thoughts...

Ten days later:

At Perchorsk, Chingiz Khuz paraded, inspected and briefed his troops, 'Khuv's Kommandos', as he had named them: a platoon of top-quality infantrymen from the famous Moskva Volunteers. Thirty armed men and machines, specially uniformed (or painted) in the colours of their task: black combat suits with white discs on the upper arms, plus the usual badges of rank with the hammer and sickle sigil blazoned over. Their vehicles -five light-weight, jeep-like trucks and trailers, plus three outrider motorcycles, all for the moment waiting in the Projekt's loading/unloading bays - were likewise black, marked on their doors and panniers with the white disc of the Gate. They bore no number plates, carried no documentation. No requirement for such encumbrances where they were going.

For the next ten days these men would sleep in a converted Projekt warehouse here 'on the premises'; they'd be briefed, given all available details of what they could expect, shown films of the same, and intensively trained in the use of one-man flame-throwers and three larger, trailer-transported units. Their mission: go into the sphere, through the Gate, and set up a base camp on the other side. They were in short an expeditionary force.

Each man was hand-picked; they left no loved ones behind, had few friends or relatives, were all volunteers as befitted the history and traditions of their parent regiment. And they were as hard as foot-soldiers come.

From the landing at the top of the wooden stairs Viktor Luchov watched Khuv strut, listened to his voice echoing up as he paraded before the platoon on the boards of the Saturn's-rings circumference, saw the goggled faces of the thirty where they stood at ease turning to follow him up and down, up and down, as he delivered his welcoming address.

Welcome - hah!

And would the hostile new world they were invading welcome them, too? - Luchov wondered. With what would it welcome them?

Finally the initial introduction to Perchorsk was over; Khuv handed over to his Sergeant-Major 2I/C; the men were fallen out, told to leave the core in an orderly fashion and return to their billets. They came up the steps single-file, passed Luchov and disappeared through the magmass levels. Khuv himself was the last to leave, and looking ahead up the steps he saw Luchov waiting for him. 'Well,' he said, as he came up the stairs to the landing, 'and what do you think of them?'

'I heard what you said to them.' Luchov's voice was cold, almost distant. 'What difference does it make what I think of them? I know where they're going, and therefore that they're dead men!'

Khuv's dark eyes were bright, less than inscrutable. There was a fever in them, which while it told of excitement refused to hint at the source. So perhaps they were inscrutable after all. 'No,' he shook his head, 'they'll survive. They are the best. Men of steel against entirely flesh-and-blood monsters. Self-supporting, working as a perfectly co-ordinated team, equipped with the best personal weapons we can given them... they'll do much better than just survive. Against the primitives we know exist through there - ' he glanced down on the shining Gate, ' - they'll appear as supermen! They're a bridgehead, Direktor, into a new world. Oh, a military bridgehead, I agree - but that's only temporary. One day soon,' (and here his eyes narrowed a little, Luchov thought) 'you, too, shall visit that other world, when they've made it safe for you. And who can say what resources will be found there? Who knows what wealth, eh? Don't you understand? They'll claim and tame that world for the USSR!'

'Pioneers?' Luchov hardly seemed impressed. They're soldiers, Major, not settlers. Their prime function isn't to farm or explore, it's to kill!'

Again Khuv shook his head. 'No, their prime function is to protect themselves and the Gate. To open it up, keep anything else from breaking through to us. From the time they go in, this Gate becomes literally - one-way. From here to there. That's what I call security.'

'And what about them?' Luchov's voice was colder than ever. 'Do they know they can't come back?'

'No, they don't,' Khuv's response was immediate, 'and they can't be told. You'd better understand that: they can't be told. I have instructions for you on that matter, and on other matters...'

'Instructions for - ' Luchov sucked in air implosively. 'You have instructions for me?'

Khuv was impassive. 'From the very highest authority. The very highest! Where those soldiers are concerned, Direktor, I am in charge.' He produced and handed Luchov a sealed envelope stamped with the Kremlin crest. 'As for not coming back: no, they won't, not immediately. But eventually...'

'Eventually?' Luchov glanced at the envelope, put it away. 'Eventually?' he snorted. 'How long do we need, man? This Gate has been here for over two years - and what have we learned about the world on the other side? Nothing! Except that it's home for ... monsters! We've never even communicated with the other side.'

'That comes first,' said Khuv. 'Field telephones.'

'What?'

'We know sound travels through the sphere,' said the other, 'and light - both ways! However warped the effect, men can talk and communicate with each other in there. These men will lay a cable as they go. It can be tested after they've travelled no more than a few paces! And if that doesn't work they'll set up temporary semaphore stations. At least we'll get to know what it's like through there. What it's like on the other side.'
