Illegal Alien

'Are you asking for asylum?' asked Frank.

'No. But if I am to answer Dale’s question, it cannot be done here. We must go somewhere else.'

'Where?'

'Northern Canada.'

'Why?'

'Arrange the passage. I will take you and Dale there, and then, I promise, we shall return to Los Angeles, and I will face justice.'

Dale sent Michiko Katayama to court the next day, to beg off, saying that Hask had suffered a relapse from his gunshot injury. Frank arranged for Hask to be smuggled out of the USC residence in a laundry container, which was driven to March Air Force Base, nine miles southeast of Riverside. From there, a U.S. military jet flew Frank, Dale, and Hask to a Canadian Forces Base in Cold Lake, Alberta. They transferred to a Canadian plane, which took them into the Northwest Territories.

Frank didn’t particularly like to fly, especially in small planes. He kept his equilibrium by thinking about his daughter, Maria, conjuring up her beautiful, wide-eyed, twelve-year-old face. So much had happened — and, it seemed, so much more was still going to happen. All his life, he’d been trying to make the world a better place, but never for himself. It had always been for her, for the children, for the future. What effect would the outcome of this trial have on humanity’s relations with the Tosoks? What kind of world would be left for Maria once the verdict was handed down? He shivered in the plane’s small cabin, and not just from the cold.

The Canadian pilot almost missed the ship. Hask’s lander had amply demonstrated its ability to change color by cycling through red, orange, yellow, green, blue, indigo, and violet while bobbing on the Atlantic. This lander, too, had changed color, to precisely match the lichen-covered rocks of the tundra. But once Hask had pointed it out, its shield shape was obvious. The plane had pontoons; the Canadian pilot put it down in a lake about a quarter mile from the alien craft. Finding a parka big enough to accommodate Dale had been a challenge, but they’d managed it. Hask was actually wearing a Tosok space suit, brought from one of the Tosok landing craft at USC. It was pale green in color and hugged his form snugly — but, he said, provided more than enough insulation to keep out the subzero cold.

They made their way ashore in an inflatable rubber boat and walked the short distance across the barren landscape to the lander, their breath escaping in clouds of condensation. A radio in his space suit allowed Hask to communicate with the lander’s occupant; when they arrived, the outer airlock door opened for them.

They cycled through the air lock — and there she was.

Seltar.

Her hide was purplish gray, and her eyes were pink and orange and ebony and navy blue. She was slightly shorter and slightly broader than Hask.

Hask touched controls on his space suit and it fell away, like a shed skin.

He rushed to Seltar. His front arm came up, as did hers, and they intertwined their eight fingers. Meanwhile his back hand came up and reached over his head to touch Seltar’s tuft; Seltar, meanwhile reached over with her back hand to stroke Hask’s tuft.

'God, it has been so long—' said Hask. He realized his translator was still on, and disengaged his front hand from Seltar’s long enough to deactivate it. They continued to embrace, and to chatter to each other for several minutes. Frank looked at Dale, slightly embarrassed.

At last the embrace ended, and Hask turned to look at the two humans. He was still holding front hands with Seltar, but he reactivated his translator with his back hand.

'Forgive us,' said Hask. 'Did I mention that Seltar is my mate?'

Frank grinned. 'No, you didn’t.'

'Well, she is. In fact, she is my four-mate — we have agreed, when the time comes, that I shall impregnate all four of her wombs.'

'You kinky devil,' said Dale, with a smile.

When Hask had spoken all those months ago of the female Tosok God, Frank thought he’d heard Hask call her the 'foremother' of the race, a feminine version of 'forefather.' He realized now that what Hask had probably really said, though, was 'four-mother.'

'Please,' said Hask, 'let me make proper introductions. Seltar, this is Dale Rice, a human attorney. And this is Frank Nobilio, a human scientist and government official. They are good people, and they are my friends.'

'How do you do, Seltar?' said Frank.

Her translated voice was identical to Hask’s — presumably Hask had simply copied the translation program from his portable computer to hers. 'I do very well, thank you,' she said.

'You’ve been here all this time?' asked Dale.

'Yes,' she said.

'But why here? Isn’t it too cold for you?'

'My space suit provides adequate protection when I feel the urge to get outside of this lander,' said Seltar, 'but when I do go outside, the light is agreeably dim. The sun does not get far above the horizon this far north.'

'Amazing,' said Dale. 'And the others all think you’re dead?'

'They do,' said Seltar. 'And we must keep it that way.'

'Why?'

'I am your only hope.'

'To clear Hask, you mean?'

Her tuft split in the now familiar Tosok shrug. 'Your language lacks sufficient pronouns. I am your only hope. I am the only hope of you.'

'Pardon?'

Hask stepped forward. 'As Cletus might have put it,‘I am the only hope of y’all.’ She means she is the last hope of the human race.'

'What?' Frank felt his eyebrows climbing.

'The things we shall tell you must remain secret,' said Seltar. 'You cannot divulge them to anyone without my permission.'

'We promise not to say anything,' said Dale.

Hask turned to Seltar. 'He is speaking the truth.'

'Then tell them,' said Seltar.

Hask turned back to the humans. 'Seltar and I belong to what you might call a different religion than the other six Tosoks, although perhaps a different philosophical school would be a better description.' He looked at Frank, then at Dale. 'The crossbreeding that is the norm among Tosoks — four males and one female involved in most unions — has led to a substantial degree of interrelation among the Tosok people. The result is that we tend to think of the survival of our race as more important than the survival of any one individual. The school Seltar and I belong to abjures that; we have seen the damage it can do. That is why we are mating exclusively with each other.'

'I don’t understand,' said Frank. 'Surely such interrelation would have all kinds of benefits. I bet you have fewer wars than we do.'

'We in fact have no wars,' said Hask. 'I was amazed to learn of the human propensity for them. But on the question of interrelation, as in all questions, one side always has more power, and in this one, the negative aspects of protecting the species at all costs are greater than the benefit.'

He paused, as if thinking about how to express himself. 'Dale, during this case we encountered at least one juror who would say and do anything to get accepted, presumably in order to ensure a particular outcome. Well, Seltar and I did everything we could to get appointed to one of the star missions.' His two front eyes blinked. 'The tragedy is that several missions did get away without any of us among the crew.'

Dale sounded confused. 'What are you talking about?'

'What do you think the purpose of the Tosok expedition to your solar system is?' asked Hask.

'Exploration, no?' said Dale. 'To see what was here?'

'No. The purpose of the mission was survival — survival of the Tosok race.'

Frank nodded, his worst fears confirmed. 'So you did come to invade Earth.'

'Invade?' Hask’s tuft waved backward. 'No. We certainly would not want to live here. Your sun is so bright and large, your air smells, and all those annoying insects! No, no, the Tosoks are quite content with our home.'

'Then what did you mean by saying your mission is survival?'

'We come from a world currently orbiting Alpha Centauri A at a distance much greater than your world orbits your sun. In fact, we orbit so far out from Centauri A that we are just on the outermost edge of orbital stability — any farther out, and the gravitational effects of Centauri B would be significant.'

'So your planet is at risk,' said Frank.

'At risk? No, not at all.'

'Then what’s the problem?'

'There is a third star in our system — Centauri C. Centauri C orbits the center of mass of the A-B system in a hugely eccentric path. Approximately every four hundred thousand Earth years it passes very close to us. When it last approached us, Centauri A was positioned between Centauri C and the center of mass of the A-B system; when it next approaches us, Centauri B will be between C and the center of mass. Indeed, since the orbital period of C is a precise multiple of the A-B orbital period, there is a perfect alternation: on one pass, A will be between C and the center of mass; on the next pass, B will be between C and the center of mass, and so on.'

'So?' said Frank.

'So mass curves space, of course, and at each near passage of C, that curvature becomes sufficient that my home world slips from orbiting around A to orbiting around B, or vice versa. We call this transfer ‘the handoff.’ Of course, there is a period of instability during the handoff. Still, when orbiting A, we ultimately settle in at a comfortably warm two AUs or so from that star. But when orbiting B, although we also settle into an orbit not much greater than two AUs from B, things are much colder, for B is a much fainter star. Our climate is temperate when we orbit A, but when we orbit B, our surface temperature drops to' — he paused, and worked controls on his pocket computer — 'almost fifty degrees below zero Celsius.'

'My God!' said Frank. 'That’s below the freezing point for carbon dioxide. It must kill everything.'

'It does not. Those lifeforms that have persisted on our world have developed a natural ability to hibernate during these times. Everything simply pauses for four hundred thousand years, until Proxima swings by again, causing a reverse handoff, bringing us back into orbit around Alpha Centauri A. Temperatures rise, the long sleep ends, and we continue on.'

'That’s incredible,' said Dale. 'I mean, wouldn’t it require enormous luck for a world to exist in a stable configuration like that?'

'Incredible? No. Unlikely perhaps, but, then again, no more unlikely than the coincidences of sizes and orbits that makes possible the kind of perfect total solar eclipse we observed from Earth’s surface. Of all the inhabited planets in the entire universe, Earth may be the only one that enjoys such a spectacle.'

'I suppose,' said Dale, 'but—'

'And, of course, there usually are such harmonics to orbital mechanics. Orbits of bodies around each other are often in perfect ratios: two-to-three, one-to-two, and so on. Your innermost planet, Mercury, for instance, revolves round your sun exactly two times for every three times that Mercury rotates around its own axis; its day is precisely two-thirds the length of its year.'
