"I'm going to lash us up in tandem," Mali said to Joe as she attached a cable from her belt to his. "This will give us twenty feet of free line. That should be enough. I can't risk getting separated from you; that might be the last we'd see of you."
The robot wordlessly handed Joe a plastic carton.
"What for?" Joe said.
"You probably will find a broken pot or two down there. And you'll want to bring the shards up."
Stalking catlike to the aperture in the floor of the staging chamber, Mali said, "Let's go." She snapped on her heliumpowered torch, glanced briefly at Joe, and then dived out of sight. The twenty-foot cable attached to him stretched taut, pulled him; it walked him to the aperture, propelling him, and then, his mind blank of any real thoughts, he dived, too. Passively.
The light of the staging chamber faded out above him. He snapped on his own torch and allowed himself to be tugged along, down and down; the water became utterly black, except for the vague, seemingly half-real quadrant illuminated by his torch. And, below him, Mali's torch glowed, like the phosphorescent light of an exceedingly deep sea-fish.
"Are you okay?" Mali's voice sounded in his ear; it startled him and then he realized that a two-way intercom connected them.
"Yes," he said.
Various fish floated past him, incurious and pompous; they gawked at him and traveled on, disappearing into the void surrounding his illuminated path.
"That windbag robot," Mali said scathingly. "My god; we must have conversed with it for twenty minutes."
But, Joe thought, we are here, now. Within the waters of Mare Nostrum, spiraling down and down.
I wonder, he thought, how many theologically inclined robots there are in the universe. Perhaps Willis was the only one... put there by Glimmung to talk at extended length, thus interfering with the attempt to go below the surface.
The heat unit of his suit snapped on; he felt the cold of the sea ebb away from him. And for that he gave thanks.
"Joe Fernwright," Mali's voice sounded in his ear. "Did it occur to you that Glimmung might have sent me here, to go below with you as we're doing, to kill you? Glimmung knows the prophecy. Wouldn't it be reasonable for him to do that? So obvious. Didn't you think at all of that?"
As a matter of fact he had not. And, thinking it now, he felt the chill of the ocean ease back into its grip around him; the enervating cold plundered his loins, his heart—he felt himself freeze, within, into frightened immobility, like a defenseless minor creature; his fear deprived him of his sense of being human, and of being a man. It was not a man's fear; it was the fear of a small animal. It shrank him, as if devolving him into ages past; it eradicated the contemporary aspects of his self, his being. God, he thought. I am feeling a fear that is millions of years old.
"On the other hand," Mali pointed out, "the text which the Kalend showed you might have been a forgery, prepared for your benefit. One single copy for your eyes alone."
Joe said hoarsely, "How did you know about the Kalend and the new text?"
"Glimmung told me."
"Then he read what I read. It isn't a forgery for my benefit. If it was you wouldn't be here."
She laughed. And said nothing. And, on and on, they spiraled downward.
"Then I can assume I'm right," Joe said.
Stark and yellow, the hull of something gleamed and putrifled within the focus of his torch. To his right, Mali's torch lit up another vertebra of it. Huge... like an ark that had been built to contain every living thing—and an ark which had sunk to the bottom of Mare Nostrum. Forever. The ark, he thought, of failure.
"What is it?" he asked Mali.
"A skeleton."
"Of what?" He thrashed toward it, sweeping out as much of it as possible with his torch. Simultaneously, Mali did the same.
She bobbed close to him, then; he could see her face through the transparent plastic disk of her oxygen mask. When she spoke, her tone was subdued, as if, despite her knowledge and experience, she had not expected to find this here.
"It's a Glimmung," she said. "The skeleton of an ancient, archaic, long-dead, forgotten Glimmung; it's coral-encrusted terribly; it's been down here, I would say, for a century at least. Good lord."
"You mean you didn't know it was here?" he demanded. "Maybe Glimmung; not me. But—" She hesitated. "I think it's a Black Glimmung."
"What's this?" Joe asked, and his uneasiness burgeoned; it filled him and became, by degrees, overwhelming dread.
"It's almost impossible to explain," Mali said. "As with antimatter; you can talk about it but you can't really imagine what the words mean. There are Glimmungs and there are Black Glimmungs. Always on a one-to-one ratio. Each individual Glimmung has his counterpart, his opaque Doppelganger. Sooner or later, during his life, he must kill his Black counterpart, or it will kill him."
"Why?" Joe said.
"Because that's the way it is. It's like asking, ‘Why is a stone?' Do you see? They--_evolved_ this way, on this strange parity basis. They are mutually exclusive, antagonistic entities, or, if you prefer, properties. Yes, properties, like chemical combinations. You see, the Black Glimmungs are not precisely alive. And yet they're not biochemically inert either. They're like malformed crystals with the formdestroying principle motivating them; tropic specifically as regards their matching Glimmung. And some say that it's not limited to Glimmungs; some say—" She broke off, staring acutely ahead. "No," she said. "Not this. Not already; not the first time."
A decaying hump of flopping fabric mingled with threads of cloth tottered toward them, propelled by the currents of murky water. It had a humanoid look, as if once, long ago, it had held itself erect, had walked on strong legs. Now it bowed from the waist, and its legs dangled as if the bones had been scooped out of them. He stared at it and it came nearer and he continued staring, because it seemed somehow to want to eddy into his vicinity... clumsily, so that its pace was slow. And yet it made progress forward. He made out its face, now.
And felt the world within him disintegrate.
"It's your corpse," Mali said. "You must understand; time down here is simply not—"
"It's blind," he said. "Its eyes—they've—rotted away. Gone. Can it see me?"
"It's aware of you. It wants—" She hesitated.
"What does it want?" he demanded, snarling at her so that she shuddered.
"It wants to talk to you," she said, then. And became totally silent; now she merely observed, merely saw. And did nothing, in either direction. She did not assist him; she did not assist his corrupted corpse. As if, he thought, she has withdrawn and is not here. I am alone with this thing.
"What should I do?" he asked her.
"Not—" She became silent once more, then abruptly said, "Don't hear what it says."
"You mean it can speak?" he demanded, appalled. He could accept what he saw; he could retain his sanity when presented with his own dead body. But he could not believe beyond that. It could not be real, not sane; it had to be the mimicry of some aquatic life-form, something which saw him and managed, in a plastic manner, to adopt the semblance of his own shape.
"It will tell you to go away," Mali said. "To leave this world, this ocean. Leave Heldscalla forever, and Glimmung's hopes, his project. See: it's already trying to form words."
The decayed flesh of the lower face writhed; he saw broken teeth and then, from within the cavity which his mouth had become, noise issued forth. A drumming, as if far off on a heavy ocean cable. Something extending for five hundred miles, something which weighed so much. Something so dense, so hard to maneuver. And yet the thing tried. The drumming continued. And finally, as it bobbed before him, rotating slow motion and rising now, then sinking a little, he distinguished one word. Then another.
