His mind was confused by his abominable nausea, yet he knew what he must do. He hurried toward the stairs with shaky strides, waving Fafhrd another vague gesture. Just as he was going out of the room he chanced to turn up his eyes, and spied something peculiar on the ceiling. What it was he did not fully realize for some moments.
Fafhrd hardly noticed the Mouser’s movements, much less his gestures. The block of stone was rapidly yielding to his efforts. He had previously experienced a faint suggestion of the Mouser’s nausea, but perhaps because of his greater single-mindedness, it had not become seriously bothersome. And now his attention was wholly concentrated on the stone. Persistent prying had edged it out a palm’s breadth from the wall. Seizing it firmly in his two powerful hands, he tugged it from one side to the other, back and forth. The dark, viscous stuff clung to it tenaciously, but with each sidewise jerk it moved forward a little.
The Mouser lurched hastily down the stairs, fighting vertigo. His feet kicked bones and sent them knocking against the walls. What was it he had seen on the ceiling? Somehow, it seemed to mean something. But he must get the girl out of the clearing. She mustn’t come any closer to the house. She mustn’t enter.
Fafhrd began to feel the weight of the stone, and knew that it was nearly clear. It was damnably heavy—almost a foot thick. Two carefully gauged heaves finished the job. The stone overbalanced. He stepped quickly back. The stone crashed ponderously on the floor. A rainbow glitter came from the cavity that had been revealed. Fafhrd eagerly thrust his head into it.
The Mouser staggered toward the doorway. It was a bloody smear he had seen on the ceiling. And just above the corpse of the holy man. But why should that be? He’d been smashed against the floor, hadn’t he? Was it blood splashed up from his lethal clubbing? But then why smeared? No matter. The girl. He must get to the girl. He must. There she was, almost at the doorway. He could see her. He felt the stone floor vibrating slightly beneath his feet. But that was his dizziness, wasn’t it?
Fafhrd felt the vibration, too. But any thought he might have had about it was lost in his wonder at what he saw. The cavity was filled to a level just below the surface of the opening, with a heavy metallic liquid that resembled mercury, except that it was night-black. Resting on this liquid was a more astonishing group of gems than Fafhrd had ever dreamed of.
In the center was a titan diamond, cut with a myriad of oddly angled facets. Around it were two irregular circles, the inner formed of twelve rubies, each a decahedron, the outer formed of seventeen emeralds, each an irregular octahedron. Lying between these gems, touching some of them, sometimes connecting them with each other, were thin, fragile-looking bars of crystal, amber, greenish tourmaline, and honey-pale orichalchum. All these objects did not seem to be floating in the metallic liquid so much as resting upon it, their weight pressing down the surface into shallow depressions, some cup-shaped, others troughlike. The rods glowed faintly, while each of the gems glittered with a light that Fafhrd’s mind strangely conceived to be refracted starlight.
His gaze shifted to the mercurous heavy fluid, where it bulged up between, and he saw distorted reflections of stars and constellations which he recognized, stars and constellations which would be visible now in the sky overhead, were it not for the concealing brilliance of the sun. An awesome wonder engulfed him. His gaze shifted back to the gems. There was something tremendously meaningful about their complex arrangement, something that seemed to speak of overwhelming truths in an alien symbolism. More, there was a compelling impression of inner movement, of sluggish thought, of inorganic consciousness. It was like what the eyes see when they close at night—not utter blackness, but a shifting, fluid pattern of many-colored points of light. Feeling that he was reaching impiously into the core of a thinking mind, Fafhrd gripped with his right hand for the diamond as big as a man’s skull.
The Mouser blundered through the doorway. There could be no mistaking it now. The close-mortised stones were trembling. That bloody smear, as if the ceiling had champed down upon the holy man, crushing him against the floor, or as if the floor had struck upward. But there was the girl, her terror-wide eyes fastened upon him, her mouth open for a scream that did not come. He must drag her away, out of the clearing.
But why should he feel that a fearful threat was now directed at himself as well? Why should he feel that something was poised above him, threatening? As he stumbled down the terraced steps, he looked over his shoulder and up. The tower. The tower! It was falling. It was falling toward him. It was dipping at him over the dome. But there were no fractures along its length. It was not breaking. It was not falling. It was bending.
Fafhrd’s hand jerked back, clutching the great, strangely faceted jewel, so heavy that he had difficulty in keeping his hold upon it. Immediately the surface of the metallic, star-reflecting fluid was disturbed. It bobbled and shook. Surely the whole house was shaking, too. The other jewels began to dart about erratically, like water insects on the surface of a puddle. The various crystalline and metallic bars began to spin, their tips attracted now to one jewel and now to another, as if the jewels were lodestone and the bars iron needles. The whole surface of the fluid was in a whirling, jerking confusion that suggested a mind gone mad because of loss of its chief part.
For an agonizing instant the Mouser stared up in amazement—frozen at the clublike top of the tower, hurling itself down upon him. Then he ducked and lunged forward at the girl, tackling her, rapidly rolling over and over with her. The tower top struck a sword’s length behind them, with a thump that jolted them momentarily off the ground. Then it jerked itself up from the pitlike depression it had made.
Fafhrd tore his gaze away from the incredible, alien beauty of the jewel-confused cavity. His right hand was burning. The diamond was hot. No, it was cold beyond belief. By Kos, the room was changing shape! The ceiling was bulging downward at a point. He made for the door, then stopped dead in his tracks. The door was closing like a stony mouth. He turned and took a few steps over the quaking floor toward the small, low window. It snapped shut, like a sphincter. He tried to drop the diamond. It clung painfully to the inside of his hand. With a snap of his wrist he whipped it away from him. It hit the floor and began to bounce about, glaring like a living star.
The Mouser and the peasant girl rolled toward the edge of the clearing. The tower made two more tremendous bashes at them, but both went yards wide, like the blows of a blind madman. Now they were out of range. The Mouser lay sprawled on his side, watching a stone house that hunched and heaved like a beast, and a tower that bent double as it thumped grave-deep pits into the ground. It crashed into a group of boulders and its top broke off, but the jaggedly fractured end continued to beat the boulders in wanton anger, smashing them into fragments. The Mouser felt a compulsive urge to take out his dagger and stab himself in the heart. A man had to die when he saw something like that.
Fafhrd clung to sanity because he was threatened from a new direction at every minute and because he could say to himself, “I know. I know. The house is a beast, and the jewels are its mind. Now that mind is mad. I know. I know.” Walls, ceiling, and floor quaked and heaved, but their movements did not seem to be directed especially at him. Occasional crashes almost deafened him. He staggered over rocky swells, dodging stony advances that were half bulges and half blows, but that lacked the speed and directness of the tower’s first smash at the Mouser. The corpse of the holy man was jolted about in grotesque mechanical reanimation.
Only the great diamond seemed aware of Fafhrd. Exhibiting a fretful intelligence, it kept bounding at him viciously, sometimes leaping as high as his head. He involuntarily made for the door as his only hope. It was champing up and down with convulsive regularity.
Watching his chance, he dived at it just as it was opening, and writhed through. The diamond followed him, striking at his legs. The carcass of Rannarsh was flung sprawling in his path. He jumped over it, then slid, lurched, stumbled, fell down stairs in earthquake, where dry bones danced. Surely the beast must die, the house must crash and crush him flat. The diamond leaped for his skull, missed, hurtled through the air, and struck a wall. Thereupon it burst into a great puff of iridescent dust.
