This was the way that an eclipsing binary must look. There was the bright disk of the smaller star, a searing white, moving steadily into occultation behind the softer glow of its orange-yellow giant companion.
Except that now the smaller star was Sol. It was hard to believe that the Sun, so small and bright, was really thousands of times the size of the nearer sphere that shone to fill a fifth of the sky. Rob looked around him for some reference point that would allow him to calibrate size and distance. There was no other disk in the sky, nothing but the hard unwinking lights of the stellar background and the diffuse glow of the nebulae.
“I wondered what was keeping you,” said a familiar voice behind him. “What do you think of it?”
Rob turned at the grated words. Regulo, gaunt and awkward, was hunched by the entrance of the viewing room. In the few weeks since he and Rob last met, his condition had visibly worsened. The rough skin of his face was scored deeper with channeled gulleys, and the white hair was sparser. Only the eyes, bright and inquisitive, were undimmed and unchanged.
“When you didn’t show up at the office, I thought you must have stopped here on the way in,” went on Regulo. “So I decided to take a look for you.” He nodded at the bulk of Lutetia, glowing in the big viewing panel. “Impressive, eh?”
Rob nodded. “It looks even better from space. You lose a lot of the impact on a viewing screen. I’m still having trouble getting used to the sheer size of it. I know the Spider must be up there somewhere, but I can’t see it. Did you put in all the modifications that I sent to you?”
“Every one.” Regulo slowly came forward to stand at Rob’s side. “You’d need a telescope to see the Spider from here. We’re still about two hundred kilometers from the surface of Lutetia. I’ll move Atlantis in close before the tap begins, so we can all have a better look at what’s going on. I didn’t want to get close too soon, or we’d have troubles with the temperature of the aquasphere.”
“Lutetia’s giving out that much heat?” Rob studied the image again. “I think there’s something a little off with your camera system on Atlantis. It’s distorting the colors that come through to the screens. What’s the surface temperature of Lutetia now?”
“About three thousand, maybe as high as thirty-one hundred. We finished the spin-up and most of the inductive heating three days ago. I could have started the tap then, but I wanted you to take another look at the Spider and see if you need to do any fine tuning before we begin.”
Rob nodded. Things had been moving faster than he expected. On the trip from Earth he’d had time to look over the materials that Howard Anson had pulled together for him. They pointed to a bizarre conclusion, but to verify it he needed time. And opportunity. He had the right equipment with him, selected and loaded before he left Earth. But when would he find a chance to use it?
Regulo was watching him closely. “Problems, Rob?” The old eyes were keen.
“Just a lot on my mind. All the reports from the beanstalk are good, but I can’t stay away too long. Landing is scheduled six days from now.”
“Understood. But you don’t need to worry. I’ve been following the work from here. Merindo has everything ready to go at the ground end, and Hakluyt’s already up there with the powersat.”
“You’re more up-to-date than I am.” Rob frowned. “I missed that report from Merindo. It must have been sent as we were on final approach here. Did he reach target tether mass yet?”
“Past it. He has a twenty-percent margin.” Regulo was turning to leave the viewing room. “The beanstalk can’t be finished and operating soon enough for me. I just saw a forecast from Sycorax showing a near-term Earth shortage of titanium. There will be a shortfall of five million tons a month, and we’re the only ones with any chance of filling it. The assay of Lutetia shows billions of tons of the metal. If we can tap it out efficiently, and have a working beanstalk, we’ll be unbeatable.”
“Can you ship in time? Even if we can mine it, we’ll still have to live with the rules for cargo ship drives in the Inner System.”
“Right.” Regulo paused in the doorway, pale eyes hooded and inscrutable. “That’s a problem, no doubt about it. But let’s see how the tap goes before we worry.”
“When do you want to start?”
“The sooner, the better. Then you can be finished and out of here. Unless you have problems with the Spider, how about shooting for twenty-four hours from now? That will give you time to work, and time to rest as well.”
“I’ll be ready. I’ll go out to the Spider now and see what needs to be done.”
Regulo nodded and limped away, leaving Rob with the unpalatable arithmetic. Twenty-four hours would provide sixteen for work on the Spider, and the other eight for preparation, exploration and — if he were correct — action. Rest or sleep would have to go. But Rob always seemed to be squeezing such luxuries out of his crowded life.
A century of space experiments had only served to confirm the strength of the circadian rhythm. After attempts at twenty-, thirty- and forty-hour days, and almost every number in between, humankind had finally accepted the constraint. Every colony on the Moon and Mars, and every outpost of the USF through the Middle and Outer System, now worked from the same premise: a day was twenty-four hours; and in each place, one third of that period was accepted as a time of reduced activity.
Rob had finished his review of the Spider, which was functioning flawlessly. Now he waited quietly in his rooms at the edge of the living-sphere for the time when the rest of Atlantis slept. Then he could begin.
Anson’s Information Service had provided him with a number of important operating factors. Item: Joseph Morel was an insomniac, sleeping only a couple of hours a day. Implication: No time of the diurnal cycle was really safe for exploration of Atlantis.
Rob had noted the point, but it made no difference to the way he must proceed. Exploration would be done when most of the inhabitants of the living-sphere were asleep. Morel was simply an added and unavoidable risk.
Item: Only four appearances of Goblins had ever been recorded, and the geographical distribution of at least the most recent three was consistent with Atlantis as their point of origin.
Item: By every reasonable index, Caliban was intelligent. Further exploration of Atlantis via the aquasphere, unless Caliban could be eliminated from the picture, would be rash verging on insane.
Rob, remembering his earlier visit to the water-world, did not need Anson’s information to keep him clear of the aquasphere. His survival then, with Caliban patrolling, seemed more and more an accident of good luck. This time, Rob would work from within.
He went across to the window partition and stared out into the clear water. The lights had been dimmed, but he fancied he could see a faint new glow diffusing through the interior of Atlantis. As they moved closer to Lutetia, the white-hot asteroid served as a second sun. Rob looked for signs of Caliban but the great squid was busy elsewhere. He forced himself to sit quietly for another half hour, even though his instincts urged him to hurry.
At last he collected the small tools that he had brought with him from Earth, stowed them in a plastic bag that fitted in his shirt pocket, and set off through the darkened corridors of the inner sphere. At this hour, the living-sphere seemed deserted; but he was sure that each corridor contained its own cameras and viewing monitors. It was an unavoidable risk, one that he had not been able to plan around.
Soon he again reached the big room with its sealed metal door. Squatting down in front of it, he forced himself to wait another quarter hour. When nothing happened in that time, he stood up and drifted across to the heavy door.
The photo-cells were first, and easiest. They took less than five minutes. After they were de-activated he turned his attention to the door itself. The design was unfamiliar and expensive-looking, but it was clearly a magnetostriction lock. He had prepared for that, and for four other possibilities. In the silent gloom he took out delicate tools from their plastic cover and began to examine the seven locking seals.
His previous experiences on Atlantis had not been wasted. Although forcing an entrance to the room might have been easier, he wanted to leave no trace of his visit. The trick was subtlety, not violence.
It was work that called for analytical skill more than manual dexterity, otherwise Rob might not have succeeded. In the past few months he had badly neglected the exercises needed to keep his hands at maximum efficiency. His concentration on the complex lock design was broken only once, when his peripheral vision thought it caught the trace of a dark shadow sweeping across the window to his left. He went quickly across to the panel and looked out. There was nothing to be seen, and after a few seconds he went back to the door.
In thirty minutes he had worked out the probable schematic for the mechanism of the lock. Ten minutes more, and he was easing the tight-fitting door open.
He came into a room with no window to the aquasphere. Two doors stood at the far end, and from this distance they looked to have the same type of locks as the one that he had just opened. Rob recalled the geometry of the living-sphere. The door on the left would logically lead to the surgery and laboratory that he had seen on his earlier visit to the aquasphere; that on the right would lead to the room that he had previously glimpsed only through its open doorway.
Rob moved to the right-hand door and began work on its lock. It was a little more complex than the first one, but experience more than made up for that. In less than twenty minutes he was easing it back on its sliding fitting.
He glanced at his watch before he entered. Too slow. Almost three of the hours that he had allotted to exploration were gone. Hurrying, he returned his sensors and pick-locks to their case, slid the plastic cover into his pocket, and moved on into the next room.
Even before he could see anything in the gloom, he felt that he was in the presence of something alive. He paused. Within, all was dark and nearly silent, but when he stood absolutely still he could hear faint sounds of movement somewhere along the right-hand wall. More than that, the sweet, cloying smell of the air told his senses that he was not alone. To his left, as his eyes became accustomed to the darkness, he could see the faint outline of the door opening that led to the surgery. At the far end of the room was a second door, also open. A dim greenish light coming through that opening suggested that this room also possessed a window looking out onto the aquasphere.
After a few more minutes, Rob’s night vision was good enough for him to see general outlines. He began to move quietly forward, a pencil light held in his left hand. At the right-hand wall he halted and shone the light downward and ahead of him.
He realized at once that his search for the Goblins was over.
A row of pallets had been placed along the wall. Each was less than seventy centimeters long, and most of them were occupied by small sleeping figures. Rob stepped closer. He shone the light onto the nearest two recumbent forms, long enough to make a visual recording of the scene on the miniaturized video he had taken from his pocket. The Goblins were a mature male and a mature female, both well-formed and symmetrical in face and figure. Neither wore clothing. When the light touched her face, the female grunted softly in her sleep and lifted a tiny, plump arm to cover her eyes.
Rob switched off the flashlight and stood silent in the darkness. These were the Goblins, beyond a doubt, but they did not match the description that he had heard before. Lenny Pascal had said that they were “ugly as sin.” The sleeping forms in front of Rob were handsome and shapely, with fine, smooth skin and regular child-like features. The male was unshaven, with a fine blond beard that was just developing.
After a few moments of thought Rob went quietly along the line of cots, flashing his light briefly on each sleeper in turn. All were naked. At the twentieth one he stopped and took a much longer look. This Goblin, a male, was of a different type. The face was old and gnarled, like the bark of a tree, and his breathing was heavy and labored, like drugged slumber. Rob bent closer, examining each feature. He recorded the image of what he was seeing, then moved on slowly along the line.
There were two main types, in roughly equal numbers: handsome elfin folk, and hideous gnomes. There seemed to be no young ones, but Rob at one point heard an infant’s cry, so faint that in other circumstances he would have dismissed it as imagination. The babies must be sleeping in another nearby room. He made a quick circuit of the room that he was in. Most of it was food and water dispensers and sanitation facilities, with no real furniture or other equipment except for the cots on which the Goblins were sleeping.
He moved on into the other area, where he had seen the green light of the aquasphere shining through the door.
This room was completely empty and had no other door. On the wall opposite the transparent panel that led to the aquasphere, Rob saw low braces mounted in secure wall fittings. He bent to take a closer look, wondering if they were used to hold the Goblins prisoner. As he did so, the lights in the room suddenly came on to full brilliance. Rob straightened and turned to the door. Standing in the entrance was Joseph Morel. His face was drained of its usual high color and he was glaring at Rob with a cold and burning anger.
Before Rob could do anything or try to explain his presence, Morel took two quick paces backward through the doorway. The heavy metal seal slid swiftly shut. Rob heard the clang of external bolts as they were drawn into position across the entrance.
With the lights of the room turned high, Rob could confirm his original impression. He was in a square chamber, almost ten meters on a side and two meters and a half high. There was a single large window, facing out towards the aquasphere. The only door had been securely blocked by Morel. Rob examined it carefully, but in the first few seconds he knew that the instruments he carried with him would be useless to move the heavy outside bolts.
Rob went quickly around the whole room, examining walls, floor and ceiling. The overhead lights could be dimmed from two stations, one near the door and the other at the far end of the area. He could darken the room when Morel returned, but it was hard to define any advantage in doing so.
Rob completed his inspection with no enthusiasm. As he expected, there was no alternate exit. Yet he felt that he had to find one. Morel had not spoken when he discovered Rob, but the look in his eyes had been unmistakable. Whatever the secret of the Goblins — and Rob was becoming increasingly sure that he understood that secret — Morel was determined to keep it. He had killed before, he would be willing to kill again. He would surely return with a weapon. Rob needed a means of self-defense, no matter how primitive. He sat down on the floor, next to the big window, and bared his left forearm. Pressing at carefully chosen points along the inner arm, he turned off all sensory inputs coming from his left hand. It was still attached to his own bones, nerves and sinews, but now beyond the wrist there was no feeling. If need be he could use it as a club or a shield with no possibility of pain.
Rob would have to get near Morel for that to be of any use. He was not optimistic that he would be given the chance. When the other man came back he would certainly have weapons or assistance, and his instinctive caution in locking Rob in at once without waiting to hear any explanation suggested that it would be impossible to trick him into coming close enough for physical attack. From the look of him, Morel was also at least as strong as Rob.
Using his deadened left hand as a convenient hammer, Rob went again around all the walls, rapping them and listening to the tone that his blows produced. It confirmed his first impression. No escape that way. The seamless planes of walls, floor and ceiling offered no chance of penetration to anything short of a drill or a power laser.
Rob sat down to think again. He needed a different angle.
After half a minute, he went to the wall control and dimmed the lights. Morel would not be fooled by darkness, but Rob wanted to take a better look at what lay outside in the quiet aquasphere. He knew it could not offer an escape. Even if he reached it, he would drown long before he could swim around to any entry point of the living-sphere. If he lived long enough to drown… Where was Caliban?
The water-world was usually illuminated only by the lights of the grid within it. Now, the extra radiation from the approaching Lutetia provided an added dim glow through the whole interior. Rob could see past the nearest nutrient dispensers, with the tangle of vegetation that grew around them. For ten minutes, he waited in the dark and silence. Was it imagination? He thought he could see a hint of a great, dark shape, hovering just beyond the fringe of plant growth. It was close to the place where he had seen Caliban on his first foray into the aquasphere. Was it too unlikely that he would be there again, watching one of the big display screens that gave him his knowledge of the external world? The distant form was tantalizingly vague and unresolved.
Rob went back to the wall control, turned the lighting up a fraction, and returned to examine the window panel. It was a standard form of construction for space use, employed wherever a vacuum seal was needed. A single sheet of tough plastic was secured to the wall opening by twelve heavy bolts, with a thick strip of adhesive seal covering them to make the fit watertight and airtight. The sealing material was designed for easy replacement. Rob peeled back an inch or two and examined the bolts beneath. As he expected they were hardened aluminum, their heads about two inches across and tightened flush with the wall.
Rob pulled all the sealing strip away from the perimeter of the window, using his left hand and forearm as a simple lever. He tried to turn one of the bolts, using the end of an electronic picklock applied to the central groove in the bolt.
It was useless. The tool had never been intended for heavy use and it bent under even a slight force. Rob swore. He needed something with a head about a quarter of an inch thick and two inches wide, something able to stand all his strength in turning it. He made another search of the room. There was nothing, no fitting that he could pry loose to use as an improvised screwdriver.
He glanced again at his watch. Morel had been gone for more than half an hour. He could return at any moment. Whatever Rob did, it had to be quick.
He went back to the wall with the restraining braces mounted close to the floor. One of the collars had a sharp edge on its metal rim, and it was set firmly enough to permit decent leverage. He squatted down and began to use the sharp rim to gouge away the soft synthetic skin of his left hand. With the input sensors to his nervous system switched off there could be no feeling of pain, but there was still an indefinable sense of discomfort as he mutilated his own surrogate flesh. Rob ignored it and pressed harder. After ten minutes of effort he had worked his way down to the hardened metal stringers that formed the skeleton for his artificial fingers. He examined the under-structure with great care. To get the straight edge that he needed, the fingers would have to be broken off in a uniform line close to their meeting place with the palm. The metal was tough, too flexible to break with a blow or a single flexing. Rob took the bared joints of his left forefinger in his right hand and forced the base of the finger as hard as he could against the sharp edge of the metal brace.
The result was a small nick in the metal. Rob repeated his action at different angles until he had a similar mark all the way around the finger. He began to twist it hard towards the thumb, using all the strength of his right hand. It gradually bent at the weakest point, by the gash that he had made. Ten minutes more of flexing, and metal fatigue had developed enough for the break to occur.
Rob examined the broken edge. It would do. It would have to. He patiently repeated the procedure for the middle finger, and then rather more quickly for the other two thinner fingers. When he was done he had four ugly ends of metal, each about a quarter of an inch thick and extending across the end of the palm of his left hand.
He paused for a few seconds. He was perspiring heavily in the close atmosphere, and blood was trickling from a cut in his right elbow where a slip as he was pressing down had brought it into contact with the sharp metal of the brace. He felt exhausted.
Don’t even think about rest.
He hurried back to the window and inserted the crude screwdriver that now formed the end of his left arm into the slit in the head of one of the bolts. He tried to turn it. His lack of weight in the low gravity of the interior of Atlantis made it difficult to get useful leverage, but he found after some experiment that he could wedge his feet firmly against the angle of floor and wall. Gripping his left forearm in his right hand, he turned it with all his strength.
After a minute of desperate effort, the head of the bolt made its first reluctant quarter turn. Rob took a deep breath, rested his forehead against the cool plastic of the window, and closed his eyes for a moment. When he opened them again and peered out into the cool green water of the aquasphere, he fancied that he could see the faint outline of Caliban, lurking within the fronded vegetation. He gritted his teeth and went back to work, wondering if desperation was forcing him to see visions in the waving weeds.
In another three minutes he could remove the first bolt. When he took it out he was relieved to see that no water entered. There must be another layer of adhesive seal on the outside of the window. Bathed in a cold sweat he worked on, bolt after awkward bolt. The work was boring and backbreaking. After the first ten minutes it became automatic, a ritual that robbed him of all sense of the passage of time. His labor began to seem more and more pointless as it grew nearer to its doubtful conclusion.
Where is Morel? How long do I have?
He worked on, blindly persistent.
Lack of sleep took its toll. Rob was semi-conscious and slumped by the wall opposite the big window when the clang of bolts from the heavy door brought him abruptly to attention. He moved across to the light control and turned it from its dimmed setting to maximum illumination. As he did so, the door slid open. Joseph Morel stood in the entrance.
He did not come inside at once. His cold grey eyes scanned the room carefully before he stepped forward. Rob thanked his own thoroughness in replacing the adhesive sealing strip at the edge of the window, and hiding the bolts he had removed in his pockets. It would take a close inspection to discover his work on the window.
Morel was taking no chances. He was carrying a heavy cylinder with a crosswired blue end piece. As he stepped cautiously inside the room he held it pointed straight at Rob’s chest.
“I presume that it is not necessary for me to describe this to you?” Morel’s voice was soft and precise.
Rob nodded. “Surgical laser.”
“Correct. If you have never seen one in operation, let me point out that this is a heavy-duty model and it is now set at maximum intensity. A full pass across your body — which I trust will not be necessary — will take maybe one fiftieth of a second. The result will be a perfect and cauterized separation.”
Morel’s face was flushed and his quiet voice vibrant with an odd excitement. Rob did not move. He knew that it would take very little on his part for the other man to find it “necessary” to employ the instrument that he was carrying.
“I don’t know what all the excitement is about,” he said mildly. “All I was doing was taking a look around your lab, then you came along and locked me in. You’ve been gone for hours. What’s this all about?”
As Rob spoke he stole a quick look at his watch. Morel had indeed been away for almost two hours. Why so long? What had he been doing? Although Rob could practically feel the laser slicing through his flesh and bone, he forced himself to edge a few feet closer to Morel. That produced a warning wave of the laser.
“Keep your distance.” Morel moved away from Rob, closer to the big window. “Don’t come one centimeter closer. I don’t think you should bother with any elaborate invention regarding your presence here.” He smiled, and Rob read the finality of his look. “You were snooping in the lab, and you saw what is in the next room. The reason for your persistent curiosity would be irrelevant, but I must know it for my own peace of mind. Why are you so interested in the experiments here?”
“It’s a long and complicated story.” Rob was staring past Morel, trying to see into the aquasphere. The intense light in the room increased the reflection from the window, but Morel was brightly illuminated.
“You already know about my father,” Rob went on.
“I don’t want a life history.” Morel waved the laser again. “I’m in a hurry. I’m sure you realize that you will not leave this part of Atlantis alive, but you still have options. You can earn a quick and painless death by making your explanation brief and economical. Or you can learn just how effective this instrument can be for extensive surgery. The death of a thousand cuts, as the Chinese so aptly describe it. Go on, and do not tempt me.”
“The death of my father is relevant.” Rob hurried on before Morel could go beyond threat to demonstration. “I’m sure you know that my parents died — were murdered — because they were experimenting with what they called `Goblins.’ “
Morel looked startled. “How could you possibly have learned that? It all happened before you were born.”
“Give me a few moments, and I’ll tell you. I found evidence that the Goblins were tied to you, and to Atlantis. When I came here the second time, I decided that I should try and find out just what the Goblins are, and why they were sufficient reason for someone to commit multiple murder.”
Rob forced himself to keep his eyes fixed on Morel’s face. At the window a thick ropy snake floated lazily by, to be followed a second later by a huge lidless eye, close to the clear plastic. Although it was what he hoped for, Rob shuddered at the sight. Another second, and a vast suckered tentacle waved into view next to the eye.
“I decided that the only place they could be was here, inside this lab.” To Rob’s dismay, the eye and tentacle at the window drifted away out of sight, as though the scene inside were of little interest. Was Morel not sufficiently recognizable from a rear view? Rob tried to hide his own interest in the window. Out of the corner of his eye, he watched as a pair of tentacles slowly floated back into view and were placed with their suckers flat along the surface of the transparent panel.
“And did you find out what it was, that would make someone commit multiple murder?” asked Morel.
The window gave a faint squeaking noise as powerful arms tested its strength.
“Not really,” said Rob. He stopped, unable to find any more words. Surely Morel could hear the sound of the window.
Fortunately it was not necessary for Rob to make further invention. Caliban had decided that the situation with this panel was different. Morel heard the sound behind him, but it was too late. As he turned around the squid seized the window in three more tentacles and ripped it effortlessly from its setting. The heavy plastic sheet swirled away into the aquasphere like a wind-blown leaf. Three long, dark-green arms came groping in through the opening, feeling for Morel. One of them seized him by the leg, another coiled firmly around his thick waist. They began to draw him toward the water.
Morel did not panic. Lifting the laser he used it to sever the two arms that held him, close to the point where they entered the room. Then he stood his ground, flushed with rage and excitement, and glared at the giant figure of Caliban hovering outside the window. The pressure difference between the air and water was very slight, and the surface between them was bulging slowly to a smooth convex meniscus. Rob cowered against the far wall, mesmerized by those tremendous tentacles. Each one was thicker than his waist. The two severed arms, convulsing with muscle spasms, spouted blue-green blood across the floor of the room.
“Get back.” Morel’s voice was triumphant. He trained the laser on Caliban as the squid threshed the water. “Back! To the outer rim — or I’ll burn all your arms off.”
The squid did not retreat. Morel reached into his pocket and pulled out the slim black communicator. He pressed a button on its side. “Get back, I say. Or I’ll give you a real lesson in what pain can be.”
It was not clear to Rob how much Caliban understood of the situation, but at the sight of the communicator the squid withdrew its third questing tentacle into the aquasphere. It was still hovering outside the window when Rob stood up by the wall, reached for the dimmer control, and turned the lights of the room completely off.
There was a moment of total darkness, then a ruby flash and the sputter of melting metal as the surgical laser discharged against the wall close to Rob. He felt droplets of molten aluminum and steel spatter his exposed arms and face. Dropping to the floor, he began to crawl towards the door. Over by the window there was a sudden grunt of pain or shock from Morel and the laser beam spun crazily from floor to ceiling. The heavy cylinder itself crashed into the wall, just a foot above Rob’s head. He felt for it and wedged it under his right arm, at the same time as he reached for the dimmer control by the door.
The lights brightened to show Morel, one tentacle around his neck and another about his hips, being pulled steadily toward the aquasphere. He still held the communicator and was keying in a sequence of command signals. Outside the window, Caliban was shuddering and convulsing, his skin a deep purple-red. But he was still dragging the man towards him. Morel was in the water, closer to the savage black beak.
Rob raised the laser and pointed it at Caliban. Before he could take accurate aim, the squid suddenly discharged its ink-sac. The aquasphere became a swirling sepia maelstrom, dark and impenetrable. Rob heard a bubbling scream. Somewhere within the dark cloud, Joseph Morel and his creation were in final combat.
Rob’s horrified trance was broken by the sight of another long tentacle groping its way out of the blackened water. Dropping the laser he dragged himself through the door, slid the metal barrier into position, and threw all the heavy outside bolts. Only when the last one was in position did he lie down by it, unmoving for several minutes.
When he at last stood up and glanced at his watch, he saw that almost five hours had passed since he set out to explore the secrets of Morel’s laboratory. Regulo would be in his study, waiting for Rob and busy with the final preparations for the mining of Lutetia.
Rob, dizzy with emotion and fatigue, staggered back toward the main living quarters.
