Halfway between them and us Norhala and Ruth drifted; I could catch no hint of voluntary motion on their part and knew that they were not walking, but were being borne onward by some manifestation of that same force which held us motionless.
I forgot them in my contemplation of the Disk.
It was oval, twenty feet in height, I judged, and twelve in its greatest width. A broad band, translucent as sun golden chrysolite, ran about its periphery.
Set within this zodiac and spaced at mathematically regular intervals were nine ovoids of intensely living light. They shone like nine gigantic cabochon cut sapphires; they ranged from palest, watery blue up through azure and purple and down to a ghostly mauve shot with sullen undertones of crimson.
In each of them was throned a flame that seemed the very fiery essence of vitality.
The — BODY— was convex, swelling outward like the boss of a shield; shimmering rosy-gray and crystalline. From the vital ovoids ran a pattern of sparkling threads, irised and brilliant as floss of molten jewels; converging with interfacings of spirals, of volutes and of triangles into the nucleus.
And that nucleus, what was it?
Even now I can but guess — brain in part as we understand brain, certainly; but far, far more than that in its energies, its powers.
It was like an immense rose. An incredible rose of a thousand close clustering petals. It blossomed with a myriad shifting hues. And instant by instant the flood of varicolored flame that poured into its petalings down from the sapphire ovoids waxed and waned in crescendoes and diminuendoes of relucent harmonies — ecstatic, awesome.
The heart of the rose was a star of incandescent ruby.
From the flaming crimson center to aureate, flashing penumbra it was instinct with and poured forth power — power vast and conscious.
Not with that same completeness could I realize the ministering star shapes, half hidden as they were by the Disk. Their radiance was less, nor had they its miracle of pulsing gem fires. Blue they were, blue of a peculiar vibrancy, and blue were the glistening threads that ran down from blue-black circular convexities set within each of the points visible to me.
Unlike in shape, their flame of vitality dimmer than the ovoids of the Disk’s golden zone, still I knew that they were even as those — ORGANS, organs of unknown senses, unknown potentialities. Their nuclei I could not observe.
The floating figures had drawn close to that disk and had paused.
And on the moment of their pausing I felt a surge of strength, a snapping of the spell that had bound us, an instantaneous withdrawal of the inhibiting force. Ventnor broke into a run, holding his rifle at the alert. We raced after him; were close to the shining shapes. And, gasping, we stopped short not a dozen paces away.
For Norhala had soared up toward the flaming rose of the Disk as though lifted by gentle, unseen hands. Close to it for an instant she swung. I saw the exquisite body gleam through her thin robes as though bathed in soft flames of rosy pearl.
Higher she floated, and toward the right of the zodiac. From the edges of three of the ovoids swirled a little cloud of tentacles, gossamer filaments of opal. They whipped out a full yard from the Disk’s surface, touching her, caressing her.
For a moment she hung there, her face hidden from us; then was dropped softly to her feet and stood, arms stretched wide, her copper hair streaming cloudily about her regal head.
And up past her floated Ruth, levitated as had been she — and her face, ecstatic as though she were gazing into Paradise, yet drenched with the tranquillity of the infinite. Her wide eyes stared up toward that rose of splendors through which the pulsing colors now raced more swiftly. She hung poised before it while around her head a faint aureole began to form.
Again the gossamer threads thrust forth, searched her. They ran over her rough clothing — perplexedly. They coiled about her neck, stole through her hair, brushed shut her eyes, circled her brow, her breasts, girdled her.
Weirdly was it like some intelligence observing, studying, some creature of another species — puzzled by its similarity and unsimilarity with the one other creature of its kind it knew, and striving to reconcile those differences. And like such a questioning brain calling upon others for counsel, it swung Ruth upward to the watching star at the right.
A rifle shot rang out.
Another — the reports breaking the silence like a profanation. Unseen by either of us, Ventnor had slipped to one side where he could cover the core of ruby flame that must have seemed to him the heart of the Disk’s rose of fire. He knelt a few yards away, white lipped, eyes cold gray ice, sighting carefully for a third shot.
“Don’t! Martin — don’t fire!” I shouted, leaping toward him.
“Stop! Ventnor —” Drake’s panic cry mingled with my own.
But before we could reach him, Norhala flew to him, like a darting swallow. Down the face of the Disk glided the upright body of Ruth, struck softly, stood swaying.
And out of the blue-black convexity within a star point of one of the opened pyramids a lance of intense green flame darted, a lightning bolt as real as any hurled by tempest, upon Ventnor.
The shattered air closed behind the streaming spark with the sound of breaking glass.
It struck — Norhala.
It struck her. It seemed to splash upon her, to run down her like water. One curling tongue writhed over her bare shoulder and leaped to the barrel of the rifle in Ventnor’s hands. It flashed up it and licked him. The gun was torn from his grip, hurled high in air, exploding as it went. He leaped convulsively from his knees and dropped.
I heard a wailing, low, bitter and heartbroken. Past us ran Ruth, all dream, all unearthliness gone from a face now a tragic mask of human woe and terror. She threw herself down beside her brother, felt of his heart; then raised herself upon her knees and thrust out supplicating hands to the shapes.
“Don’t hurt him any more! He didn’t mean it!” she cried out to them piteously — like a child. She reached up, caught one of Norhala’s hands. “Norhala — don’t let them kill him. Don’t let them hurt him any more. Please!” she sobbed.
Beside me I heard Drake cursing.
“If they touch her I’ll kill the woman! I will, by God I will!” He strode to Norhala’s side.
“If you want to live, call off these devils of yours.” His voice was strangled.
She looked at him, wonder deepening on the tranquil brow, in the clear, untroubled gaze. Of course she could not understand his words — but it was not that which made my own sick apprehension grow.
It was that she did not understand what called them forth. Did not even understand what reason lay behind Ruth’s sorrow, Ruth’s prayer.
And more and more wondering grew in her eyes as she looked from the threatening Drake to the supplicating Ruth, and from them to the still body of Ventnor.
“Tell her what I say, Goodwin. I mean it.”
I shook my head. That was not the way, I knew. I looked toward the Disk, still flanked with
