Beside him, he saw, the wizard lay tightly trussed. The nightmare beings were moving in an orderly rush toward the room in which Elak had sensed the surges of tremendous power, where lay the little brown stone. They vanished beyond the curtain, and beside Elak and the wizard there remained only Getsi. He stood looking down at the two, his white face immobile.
"What treachery is this?" Elak asked with no great hopefulness. "Set me free and give me my gold."
But Gesti merely said, "You won't need it. You will die very soon."
"Eh? Why―"
"Fresh human blood is needed. That's why we didn't kill you or Zend. We need your blood. We'll be ready soon."
An outbrust of sibilant whispers came from beyond the silver drape. Elak said unsteadily, "What manner of demons are those?"
The wizard gasped, "You ask him? Did you not know―"
Gesti lifted gloved hands and removed his face. Elak bit his lips to choke back a scream. Now he knew why Gesti's face had seemed so immobile. It was a mask.
Behind it were the parrot–like beak and fish–like eyes Elak now knew all too well. The gray robes sloughed off; the gloves dropped from the limber tips of tentacles. From the horrible beak came the sibilant whisper of the monster:
"Now you know whom you served."
The thing that had called itself Gesti turned and progressed—that was the only way to describe its method of moving—to the curtain behind which its fellows had vanished. It joined them. – Zend was staring at Elak. "You did not know? You served them, and yet did not know?"
"By Ishtar, no!" Elak swore. "D'you think I'd have let those—those—what are they? What are .they going to do?"
"Roll over here," Zend commanded. "Maybe I can loosen your bonds."
Elak obeyed, and the wizard's fingers worked deftly.
"I doubt—no human hands tied these knots. But―"
"What are they?" Elak asked again. "Tell me, before I go mad thinking hell has loosed its legions on Atlantis." /
"They are the children of Dagon," Zend said. "Their dwelling–place is in the great deeps of the ocean. Have you never heard of the unearthly ones who worship Dagon?"
"Yes. But I never believed―"
"Oh, there's truth in the tale. Eons and unimaginable eons ago, before mankind existed on earth, only the waters existed. There was no land. And from the slime there sprang up a race of beings which dwelt in the sunken abysses of the ocean, inhuman creatures that worshipped Dagon, their god. When eventually the waters receded and great continents arose, these beings were driven down to the lowest depths. Their mighty kingdom, that had once stretched from pole to pole, was shrunken as the huge land masses lifted. Mankind came—but from whence I do not know— and civilizations arose. Hold still. These cursed knots―"
"I don't understand all of that," Elak said, wincing as the wizard's nail dug into his wrist. "But go on."
"These things hate man, for they feel that man has usurped their kingdom. Their greatest hope is .to sink the continents again, so that the seas will roll over all the earth, and not a human being will survive. Their power will embrace the whole world, as it once did eons ago. They are not human, you see, and they worship Dagon. They want no other gods worshipped on Earth. Ishtar, dark Eblis, even Poseidon of the sunlit seas…. They will achieve their desire now, Hear."
"Not if I can get free," Elak said. "How do the knots hold?"
"They hold," the wizard said discouragedly. "But one strand is loose. My fingers are raw. The—the red globe is broken?"
"No," Elak said. "Some cords were torn loose as I fought with your slave, and the light went out of it. Why?"
"The gods be thanked!" Zend said fervently. "If I can repair the damage and light the globe again, the children of Dagon will die. That's the purpose of it. The rays it emits destroy their bodies, which are otherwise invulnerable, or almost so. If I hadn't had the globe, they'd have invaded my palace and killed me long ago."
"They have a tunnel under the cellars," Elak said.
"I see. But they dare'd not invade the palace while the globe shone, for the light–rays would have killed them. Curse these knots! If they accomplish their purpose―"
"What's that?" Elak asked—but he had already guessed the answer.
"To sink Atlantis! This island–continent would have gone down beneath the sea long ago if I hadn't pitted my magic and my science against that of the children of Dagon. They are masters of the earthquake, and Atlantis rests on none too solid a foundation. Their power is sufficient to sink Atlantis forever beneath the sea. But within that room"—Zend nodded toward the curtain that hid the sea–bred horrors— "in that room there is power far stronger than theirs. I have drawn strength from the stars, and the cosmic sources beyond the universe. You know nothing of my power. It is enough—more than enough—to keep Atlantis steady on its foundation, impregnable against the attacks of Dagon's breed. They have destroyed other lands before Atlantis."
Hot blood dripped on Elak's hands as the wizard tore at the cords.
"Aye … other lands. There were races that dwelt on Earth before man came. My powers have shown me a sunlit island that once reared far to the south, an island where dwelt a race of beings tall as trees, whose flesh was hard as stone, and whose shape was so strange you could scarcely comprehend it. The waters rose and covered that island, and its people died. I have seen a gigantic mountain that speared up from a waste of tossing waters, in Earth's youth, and in the towers and minarets that crowned its summit dwelt beings like sphinxes, with the heads of beasts and gods and whose broad wings could not save them when the cataclysm came. For ruin came to the city of the sphinxes, and it sank beneath the ocean—destroyed by the children of Dagon. And there was―"
"Hold!" Elak's breathless whisper halted the wizard's voice. "Hold! I see rescue, Zend."
' "Eh?" The wizard screwed his head around until he too saw the short, ape–featured man who was running silently across the room, knife in hand. It was Lycon, whom Elak had left slumbering in the underground denofGesti. ,
The knife flashed and Elak and Zend were free. Elak said swiftly, "Up the stairs, wizard. Repair your magic globe, since you say its light will kill these horrors. We'll hold the stairway." .
Without a word the gray dwarf sped silently up the steps and was gone. Elak turned to Lycon.
"How the devil―"
Lycon blinked wide blue eyes. "I scarcely know, Elak. Only when you were carrying me out of the tavern and the soldier screamed and ran away I saw something that made me so drunk I couldn't remember what it was. I remembered only a few minutes ago, back downstairs somewhere. A face that looked like a gargoyle's, with a terrible great beak and eyes like Midgard Serpent's. And I remembered I'd seen Gesti put a mask over the awful face just before you turned there in the alley. So I knew Gesti was probably a demon."
"And so you came here," Elak commented softly. "Well, it's a good thing for me you did. I—what's the matter?" Lycon's blue eyes were bulging.
"Is this your demon?" the little man asked, pointing.
Elak turned, and smiled grimly. Facing him, her face puzzled and frightened, was the girl on whom Zend had been experimenting—the maiden whose soul he had been about to unleash to serve him when Elak had arrived. Her eyes were open now, velvet–soft and dark, and her white body gleamed against the silver–black drape.
