If a storehouse of knowledge had existed here, little sign of it remained. There was a great flat floor, flagged in white stone, now chalky, broken and inter-thrust by weeds. Around this floor rose a series of monoliths, pocked and worn, and toppled off at various heights. These at one time had supported a vast roof; now of roof there was none and the walls were but dreams of the far past.

So here was the flat floor bounded by the broken stumps of pillars, bare to the winds of time and the glare of cool red sun. The rains had washed the marble, the dust from the mountains had been laid on and swept off, laid on and swept off, and those who had built the Museum were less than a mote of this dust, so far and forgotten were they.

“Think,” said Guyal, “think of the vastness of knowledge which once was gathered here and which is now one with the soil — unless, of course, the Curator has salvaged and preserved.”

Shierl looked about apprehensively. “I think rather of the portal, and that which awaits us … Guyal,” she whispered, “I fear, I fear greatly … Suppose they tear us apart? Suppose there is torture and death for us? I fear a tremendous impingement, the shock of horror …”

Guyal’s own throat was hot and full. He looked about with challenge. “While I still breathe and hold power in my arms to fight, there will be none to harm us.”

Shierl groaned softly. “Guyal, Guyal, Guyal of Sfere — why did you choose me?”

“Because,” said Guyal, “my eye went to you like the nectar moth flits to the jacynth; because you were the loveliest and I thought nothing but good in store for you.”

With a shuddering breath Shierl said, “I must be courageous; after all, if it were not I it would be some other maid equally fearful … And there is the portal.”

Guyal inhaled deeply, inclined his head, and strode forward. “Let us be to it, and know …”

The portal opened into a nearby monolith, a door of flat black metal. Guyal followed the trail to the door, and rapped staunchly with his fist on the small copper gong to the side.

The door groaned wide on its hinges, and cool air, smelling of the under-earth, billowed forth. In the black gape their eyes could find nothing.

“Hola within!” cried Guyal.

A soft voice, full of catches and quavers, as if just after weeping, said, “Come ye, come ye forward. You are desired and awaited.”

Guyal leaned his head forward, straining to see. “Give us light, that we may not wander from the trail and bottom ourselves.”

The breathless quaver of a voice said, “Light is not needed; anywhere you step, that will be your trail, by an arrangement so agreed with the Way-Maker.”

“No,” said Guyal, “we would see the visage of our host. We come at his invitation; the minimum of his guest-offering is light; light there must be before we set foot inside the dungeon. Know we come as seekers after knowledge; we are visitors to be honored.”

“Ah, knowledge, knowledge,” came the sad breathlessness. “That shall be yours, in full plentitude — knowledge of many strange affairs; oh, you shall swim in a tide of knowledge —”

Guyal interrupted the sad, sighing voice. “Are you the Curator? Hundreds of leagues have I come to bespeak the Curator and put him my inquiries. Are you he?”

“By no means. I revile the name of the Curator as a treacherous non-essential.”

“Who then may you be?”

“I am no one, nothing. I am an abstraction, an emotion, the ooze of terror, the sweat of horror, the shake in the air when a scream has departed.”

“You speak the voice of man.”

“Why not? Such things as I speak lie in the closest and dearest center of the human brain.”

Guyal said in a subdued voice, “You do not make your invitation as enticing as might be hoped.”

“No matter, no matter; enter you must, into the dark and on the instant, as my lord, who is myself, waxes warm and languorous.”

“If light there be, we enter.”

“No light, no insolent scorch is ever found in the Museum.”

“In this case,” said Guyal, drawing forth his Scintillant Dagger, “I innovate a welcome reform. For see, now there is light!”

From the under-pommel issued a searching glare; the ghost tall before them screeched and fell into twinkling ribbons like pulverized tinsel. There were a few vagrant motes in the air; he was gone.

Shierl, who had stood stark and stiff as one mesmerized, gasped a soft warm gasp and fell against Guyal. “How can you be so defiant?”

Guyal said in a voice half-laugh, half-quaver, “In truth I do not know … perhaps I find it incredible that Destiny would direct me from pleasant Sfere, through forest and crag, into the northern waste, merely to play the role of cringing victim. Disbelieving so inconclusive a destiny, I am bold.”

He moved the dagger to right and left, and they saw themselves to be at the portal of a keep, cut from concreted rock. At the back opened a black depth. Crossing the floor swiftly, Guyal kneeled and listened.

He heard no sound. Shierl, at his back, stared with eyes as black and deep as the pit itself, and Guyal, turning, received a sudden irrational impression of a sprite of the olden times — a creature small and delicate, heavy with the weight of her charm, pale, sweet, clean.

Leaning with his glowing dagger, he saw a crazy rack of stairs voyaging down into the dark, and his light showed them and their shadows in so confusing a guise that he blinked and drew back.

Shierl said, “What do you fear?”

Guyal rose, turned to her. “We are momentarily untended here in the Museum of Man, and we are impelled forward by various forces; you by the will of your people; I, by that which has driven me since I first tasted air … If we stay here we shall be once more arranged in harmony with the hostile pattern. If we go forward boldly, we may so come to a position of strategy and advantage. I propose that we set forth in all courage, descend these stairs and seek the Curator.”

“But does he exist?”

“The ghost spoke fervently against him.”

“Let us go then,” said Shierl. “I am resigned.”

Guyal said gravely, “We go in the mental frame of adventure, aggressiveness, zeal. Thus does fear vanish and the ghosts become creatures of mind-weft; thus does our élan burst the under-earth terror.”

“We go.”

They started down the stairs.

Back, forth, back, forth, down flights at varying angles, stages of varying heights, treads at varying widths, so that each step was a matter for concentration. Back, forth, down, down, down, and the black-barred shadows moved and jerked in bizarre modes on the walls.

The flight ended, they stood in a room similar to the entry above. Before them was another black portal, polished at one spot by use; on the walls to either side were inset brass plaques bearing messages in unfamiliar characters.

Guyal pushed the door open against a slight pressure of cold air, which, blowing through the aperture, made a slight rush, ceasing when Guyal opened the door farther.

“Listen.”

It was a far sound, an intermittent clacking, and it held enough fell significance to raise the hairs at Guyal’s neck. He felt Shierl’s hand gripping his with clammy pressure.

Dimming the dagger’s glow to a glimmer, Guyal passed through the door, with Shierl coming after. From afar came the evil sound, and by the echoes they knew they stood in a great hall.

Guyal directed the light to the floor: it was of a black resilient material. Next the wall: polished stone. He permitted the light to glow in the direction opposite to the sound, and a few paces distant they saw a bulky black case, studded with copper bosses, topped by a shallow glass tray in which could be seen an intricate concourse of metal devices.

With the purpose of the black cases not apparent, they followed the wall, and as they walked similar cases appeared, looming heavy and dull, at regular intervals. The clacking receded as they walked; then they came to a right angle, and turning the corner, they seemed to approach the sound. Black case after black case passed; slowly, tense as foxes, they walked, eyes groping for sight through the darkness.
