I muttered. "Nonsense, Ruth. What do you think she is— a goddess, a spirit of the Himalayas? She's as human as you or I."
"No." Even in the darkness I could sense the stubborn shake of her curly head. "Not all human. Or how could she have commanded those things? Or have summoned the lightnings that blasted the tunnel's mouth? And her skin and hair—they're too WONDERFUL, Walter.
"Why, she makes me look—look coarse. And the light that hovers about her—why, it is by that light we are making our way. And when she touched me—I—I glowed—all through.
"Human, yes—but there is something else in her—something stronger than humanness, something that—makes it sleep!" she added astonishingly.
The ground was level as a dancing floor. We followed the enigmatic glow —emanation, it seemed to me—from Norhala which was as a light for us to follow within the darkness. The high ribbon of sky had vanished —seemed to be overcast, for I could see no stars.
Within the darkness I began again to sense faint movement; soft stirring all about us. I had the feeling that on each side and behind us moved an invisible host.
"There's something moving all about us—going with us," Ruth echoed my thought.
"It's the wind," I said, and paused—for there was no wind.
From the blackness before us came a succession of curious, muffled clickings, like a smothered mitrailleuse. The luminescence that clothed Norhala brightened, deepening the darkness.
"Cross!"
She pointed into the void ahead; then, as we started forward, thrust out a hand to Ruth, held her back. Drake and Ventnor drew close to them, questioningly, anxious. But I stepped forward, out of the dim gleaming.
Before me were two cubes; one I judged in that uncertain light to be six feet high, the other half its bulk. From them a shaft of pale-blue phosphorescence pierced the murk. They stood, the smaller pressed against the side of the larger, for all the world like a pair of immense nursery blocks, placed like steps by some giant child.
As my eyes swept over them, I saw that the shining shaft was an unbroken span of cubes; not multi-arched like the Lilliputian bridge of the dragon chamber, but flat and running out over an abyss that gaped at my very feet. All of a hundred feet they stretched; a slender, lustrous girder crossing unguessed depths of gloom. From far, far below came the faint whisper of rushing waters.
I faltered. For these were the blocks that had formed the body of the monster of the hollow, its flailing arms. The thing that had played so murderously with the armored men.
And now had shaped itself into this anchored, quiescent bridge.
"Do not fear." It was the woman speaking, softly, as one would reassure a child. "Ascend. Cross. They obey me."
I stepped firmly upon the first block, climbed to the second. The span stretched, sharp edged, smooth, only a slender, shimmering line revealing where each great cube held fast to the other.
I walked at first slowly, then with ever-increasing confidence, for up from the surface streamed a guiding, a holding force, that was like a host of little invisible hands, steadying me, keeping firm my feet. I looked down; the myriads of enigmatic eyes were staring, staring up at me from deep within. They fascinated me; I felt my pace slowing; a vertigo seized me. Resolutely I dragged my gaze up and ahead; marched on.
From the depths came more clearly the sound of the waters. Now there were but a few feet more of the bridge before me. I reached its end, dropped my feet over, felt them touch a smaller cube, and descended.
Over the span came Ventnor. He was leading his laden pony. He had bandaged its eyes so that it could not look upon the narrow way it was treading. And close behind, a hand resting reassuringly upon its flank, strode Drake, swinging along carelessly. The little beast ambled along serenely, sure-footed as all its mountain kind, and docile to darkness and guidance.
Then, an arm about Ruth, floated Norhala. Now she was beside us; dropped her arm from Ruth; glided past us. On for a hundred yards or more we went, and then she drew us a little toward the unseen canyon wall.
She stood before us, shielding us. One golden call she sent.
I looked back into the darkness. Something like an enormous, dimly shimmering rod was raising itself. Higher it rose and higher. Now it stood, upright, a slender towering pillar, a gigantic slim figure whose tip pointed a full hundred feet in the air.
Then slowly it inclined itself toward us; drew closer, closer to the ground; touched and lay there for an instant inert. Abruptly it vanished.
But well I knew what I had seen. The span over which we had passed had raised itself even as had the baby bridge of the fortress; had lifted itself across the chasm and dropping itself upon the hither verge had disintegrated into its units; was following us.
A bridge of metal that could build itself—and break itself. A thinking, conscious metal bridge! A metal bridge with volition—with mind—that was following us.
There sighed from behind a soft, sustained wailing; rapidly it neared us. A wanly glimmering shape drew by; halted. It was like a rigid serpent cut from a gigantic square bar of cold blue steel.
Its head was a pyramid, a tetrahedron; its length vanished in the further darkness. The head raised itself, the blocks that formed its neck separating into open wedges like a Brobdignagian replica of those jointed, fantastic, little painted reptiles the Japanese toy-makers cut from wood.
It seemed to regard us—mockingly. The pointed head dropped— past us streamed the body. Upon it other pyramids clustered—like the spikes that guarded the back of the nightmare Brontosaurus. Its end came swiftly into sight—its tail another pyramid twin to its head.
It FLIRTED by—gaily; vanished.
I had thought the span must disintegrate to follow—and it did not need to! It could move as a COMPOSITE as well as in UNITS. Move intelligently, consciously—as the Smiting Thing had moved.
"Come!" Norhala's command checked my thoughts; we fell in behind her. Looking up I caught the friendly sparkle of a star; knew the cleft was widening.
The star points grew thicker. We stepped out into a valley small as that hollow from which we had fled; ringed like it with heaven-touching summits. I could see clearly. The place was suffused with a soft radiance as though into it the far, bright stars were pouring all their rays, filling it as a cup with their pale flames.
It was luminous as the Alaskan valleys when on white arctic nights they are lighted, the Athabascans believe, by the gleaming spears of hunting gods. The walls of the valley seemed to be drawn back into infinite distances.
The shimmering mists that had nimbused Norhala had vanished—or merging into the wan gleaming had become one with it.
I stared straight at her, striving to clarify in my own clouded thought what it was that I had sensed as inhuman—never of OUR world or its peoples. Yet this conviction came not because of the light that had hovered about her, nor of her summonings of the lightnings; nor even of her control of those—things—which had smitten the armored men and spanned for us the abyss.
All of that I was certain lay in the domain of the explicable, could be resolved into normality once the basic facts were gained.
Suddenly, I knew. Side by side with what we term the human there dwelt within this woman an actual consciousness foreign to earth, passionless, at least as we know passion, ordered, mathematical—an emanation of the eternal law which guides the circling stars.
This it was that had moved in the gestures which had evoked the lightnings. This it was that had spoken in the song which were those gestures transformed into sound. This it was that something greater than my consciousness knew and accepted.
Something which shared, no—that reigned, serene and untroubled, upon the throne of her mind; something utterly UNCOMPREHENDING, utterly
