The blood stilled within me. A slow tide of ice crept with iron lethargy into my brain and cold wariness engulfed me.
Only in the eyes of the Gorgon fire burned:
Deadly radiations were there, what Earth-scientists call ectogenetic rays, but limited till now to the plant- world. Only the mad mutation that had created Edeyrn could have brought from hell such a nightmare trick of biology.
But I did not fall. I did not die. The radiations were filtered, made harmless, by the vibration-warping properties of the Mask I wore.
I lifted the Wand of Power.
Red fires blasted from it. Scarlet, licking tongues seared out toward Edeyrn.
Lashes of flame tore at her, like crimson whips that burned and left bloody weals on that calm child- face.
She drew back, the lance of her stare driving at me.
With her, step by step, retreated Medea. Toward the foot of the great stairway that led to Llyr's Window.
The whips of fire seared across her eyes.
She turned and, stumbling, began to run up the stairway. Medea paused, her arms lifted in an uncompleted gesture. But in my face she read no softening.
She, too, turned, and followed Edeyrn.
I dropped the useless sword of steel. Wand in left hand, the Sword Called Llyr in my right, I followed them.
As my foot touched the first step, a trembling vibration shook the violet air about me. Now almost I regretted having called upon Llyr to break Medea's spell. For Llyr was awake, watching, and warned.
The pulse of Llyr muttered through the huge Caer. The golden lightnings flamed from the Window high above.
Briefly two black small silhouettes showed against that amber glow. They were Edeyrn and Medea, climbing.
After them I went. And at each step the way grew harder. I seemed to walk through a thickening, invisible torrent dot was like a wind or a wave flowing down from that shining window, striving to tear me from my foothold, to rip the crystal sword from my grip.
Up and up I went. Now the Window was a glaring blaze of yellow fires. The lightnings crackled out incessantly, while rocking crashes of thunder reverberated along the vaulted abysses of the Caer. I leaned forward as though against a gale. Doggedly I fought my way up the stair.
There was someone behind me.
I did not turn. I dared not, for fear the torrent would sweep me from my place. I crawled up the last few steps, and came out on a level platform of stone, a disc-shaped dais, on which stood a ten-foot cube. Three of its sides were of black rock. The side that faced me was a glaring blaze of amber brilliance.
Far below, dizzyingly far, was the floor of the Caer. Behind me the stairway ran down to those incredible depths, and the tremendous wind still blew upon me, pouring out from the Window, seeking to whirl me to my death.
To the Window's left stood Edeyrn, to its right, Medea. And in the Window -
The blazing golden clouds whirled, thickened, tossed like storm-mists, while still the blinding flashes spurted from them. The thunder never ceased now. But it pulsed. It rose and fell in steady cadence, in unison with the heart-beat of Llyr.
Monster or mutation – human once, or half-human – Llyr had grown in power since then. Ghast Rhymi had warned me.
Part machine and part pure energy and part something unthinkable, the power of Llyr blasted through the golden clouds upon me!
The Wand of Power dropped from my hand. I lifted the crystal sword and managed one forward step. Then the helltide caught me, and I could advance no further. I could only fight, with every bit of my strength, against the avalanche that strove to thrust me toward the edge of the hanging platform.
Louder grew the thunders. Brighter the lightnings flamed.
The cold stare of Edeyrn chilled me. Medea's face was inhuman now. Yellow clouds boiled out from the Window and caught Edeyrn and Medea in their embrace.
Then they rolled toward me and overwhelmed me.
Dimly I could see the brighter glow that marked Llyr's Window. And two vague silhouettes, Edeyrn and Medea.
I strove to step forward. Instead I was borne back toward the edge – back and back.
Great arms caught me about the waist. A braid of white hair tossed by my eyes. The giant strength of Freydis stood like a wall of iron between me and the abyss.
From the corner of my eye I saw that she had wound a scrap torn from her white robe about her head, shielding her from the Gorgon's stare. Blindly, guided by some strange instinct, the Valkyrie thrust me forward.
Against us the golden clouds rolled, sentient, palpable, veined with white lightnings and shaking with deep thunders.
Freydis strove silently. I bent forward like a bow, battering against the torrent.
Step by step I won forward, Freydis to aid me. Ever she stood as a bulwark against my back. I could hear her panting breath, great gasps that ripped from her throat as she linked her strength with mine.
My chest felt as though a white-hot core of iron was driven through it. Yet I went on. Nothing existed now but that golden brightening amid the clouds, clouds of creation, sentient with the shaking tumult of breaking universes, worlds beyond worlds crashing into ruin under the power of Llyr…
I stood before the Window.
Without volition my arm swept up. I brought the Sword Called Llyr smashing down upon Llyr's Window.
In my hand the sword broke.
It fell to tinkling fragments at my feet. The veined blue glimmers writhed and coiled about the broken blade.
Were sucked into the Window.
Back rushed the cloud-masses. A tremendous, nearly unbearable vibration ripped through the Caer, shaking it like a sapling. The golden clouds were drawn through the Window.
With them went Edeyrn and Medea!
One glimpse I had of them, the brand of my fire like a red mask across Edeyrn's eyes, Medea's face despairing and filled with a horror beyond life, her gaze fixed on me with an imploring plea that was infinitely terrible. Then they vanished!
For one instant I saw through the Window. I saw something beyond space and time and dimension, a writhing, ravening chaos that bore down upon Medea and Edeyrn and a golden core of light that I knew for Llyr.
Once almost human, Llyr, at the end, bore no relation to anything remotely human.
The grinding millstones of Chaos crushed the three!
The thunder died.
Before me stood the altar of Llyr. But it held no Window, now. All four sides were of black, dead stone!
XVI. Self Against Self
BLACKNESS AND BLACK STONES were the last things I saw, before dark oblivion closed down over me like folding wings. It was as if Llyr's terrible resistance was all that had held me upright in the last fierce stages of our struggle. As he fell, so fell Ganelon at the foot of the Windowless altar.
How long I lay there I do not know. But slowly, slowly Caer Llyr came back around me, and I knew I was lying prostrate upon the altar. I sat up painfully, the dregs of exhaustion still stiffening my body, though I knew-I must
