—Only to those who wish to end their lives. The fire devours all who approach it.
—In my world we had many such fiery mountains, McCulloch said. They often did great destruction.
—How strange your world must have been!
—It was very beautiful, said McCulloch.
—Surely. But strange. The dry land, the fire in the air—the sun, I mean—the air-breathing creatures—yes, strange, very strange. I can scarcely believe it really existed.
—There are times, now, when I begin to feel the same way, McCulloch said.
The volcano receded in the distance; its warmth could no longer be felt; the water was dark again, and cold, and growing colder, and McCulloch could no longer detect any trace of that sulphurous aroma. It seemed to him that they were moving now down an endless incline, where scarcely any creatures dwelled.
And then he realized that the marchers ahead had halted, and were drawn up in a long row as they had been when they came to the place where the octopus held its court. Another god? No. There was only blackness ahead.
—Where are we? he asked.
—It is the shore of the great abyss.
Indeed what lay before them looked like the Pit itself: lightless, without landmark, an empty landscape. McCulloch understood now that they had been marching all this while across some sunken continent’s coastal plain, and at last they had come to—what?—the graveyard where one of Earth’s lost oceans lay buried in ocean?
—Is it possible to continue? he asked.
—Of course, said the host. But now we must swim.
Already the lobsters before them were kicking off from shore with vigorous strokes of their tails and vanishing into the open sea beyond. A moment later McCulloch’s host joined them. Almost at once there was no sense of a bottom beneath them—only a dark and infinitely deep void. Swimming across this, McCulloch thought, is like falling through time—an endless descent and no safety net.
The lobsters, he knew, were not true swimming creatures: like the lobsters of his own era they were bottom-dwellers, who walked to get where they needed to go. But they could never cross this abyss that way, and so they were swimming now, moving steadily by flexing their huge abdominal muscles and their tails. Was it terrifying to them to be setting forth into a place without landmarks like this? His host remained utterly calm, as though this were no more than an afternoon stroll.
McCulloch lost what little perception of the passage of time that he had had. Heave, stroke, onward, heave, stroke, onward, that was all, endless repetition. Out of the depths there occasionally came an upwelling of cold water, like a dull, heavy river miraculously flowing upward through air, and in that strange surging from below rose a fountain of nourishment, tiny transparent struggling creatures and even smaller flecks of some substance that must have been edible, for the lobsters, without missing a stroke, sucked in all they could hold. And swam on and on. McCulloch had a sense of being involved in a trek of epic magnitude, a once-in-many-generations thing that would be legendary long after.
Enemies roved this open sea: the free-swimming creatures that had evolved out of God only knew which kinds of worms or slugs to become the contemporary equivalents of sharks and whales. Now and again one of these huge beasts dived through the horde of lobsters, harvesting it at will. But they could eat only so much; and the survivors kept going onward.
Until at last—months, years later?—the far shore came into view; the ocean floor, long invisible, reared up beneath them and afforded support; the swimmers at last put their legs down on the solid bottom, and with something that sounded much like gratitude in their voices began once again to chant in unison as they ascended the rising flank of a new continent.
The first rays of the sun, when they came into view an unknown span of time later, struck McCulloch with an astonishing, overwhelming impact. He perceived them first as a pale greenish glow resting in the upper levels of the sea just ahead, striking downward like illuminated wands; he did not then know what he was seeing, but the sight engendered wonder in him all the same; and later, when that radiance diminished and was gone and in a short while returned, he understood that the pilgrims were coming up out of the sea. So they had reached their goaclass="underline" the still point of the turning world, the one remaining unsubmerged scrap of the former Earth.
—Yes, said the host. This is it.
In that same instant McCulloch felt another tug from the past: a summons dizzying in its imperative impact. He thought he could hear Maggie Caldwell’s voice crying across the time-winds: “Jim, Jim, come back to us!” and Bleier, grouchy, angered, muttering, “For Christ’s sake, McCulloch, stop holding on up there! This is getting expensive!” Was it all his imagination, that fantasy of hands on his wrists, familiar faces hovering before his eyes?”
“Leave me alone,” he said. “I’m still not ready.”
“Will you ever be?” That was Maggie. “Jim, you’ll be marooned. You’ll be stranded there if you don’t let us pull you back now.”
“I may be marooned already,” he said, and brushed the voices out of his mind with surprising ease.
He returned his attention to his companions and saw that they had halted their trek a little way short of that zone of light which now was but a quick scramble ahead of them. Their linear formation was broken once again. Some of the lobsters, marching blindly forward, were piling up in confused-looking heaps in the shallows, forming mounds fifteen or twenty lobsters deep. Many of the others had begun a bizarre convulsive dance: wild twitchy cavorting, rearing up on their back legs, waving their claws about, flicking their antennae in frantic circles.
—What’s happening? McCulloch asked his host. Is this the beginning of a rite?
But the host did not reply. The host did not appear to be within their shared body at all. McCulloch felt a silence far deeper than the host’s earlier withdrawals; this seemed not a withdrawal but an evacuation, leaving McCulloch in sole possession. That new solitude came rolling in upon him with a crushing force. He sent forth a tentative probe, found nothing, found less than nothing. Perhaps it’s meant to be this way, he thought. Perhaps it was necessary for him to face this climactic initiation unaided, unaccompanied.
Then he noticed that what he had taken to be a weird jerky dance was actually the onset of a mass molting prodrome. Hundreds of the lobsters had been stricken simultaneously, he realized, with that strange painful sense of inner expansion, of volcanic upheaval and stress: that heaving and rearing about was the first stage of the splitting of the shell.
And all of the molters were females.
Until that instant McCulloch had not been aware of any division into sexes among the lobsters. He had barely been able to tell one from the next; they had no individual character, no shred of uniqueness. Now, suddenly, strangely, he knew without being told that half of his companions were females, and that they were molting now because they were fertile only when they had shed their old armor, and that the pilgrimage to the place of the dry land was the appropriate time to engender the young. He had asked no questions of anyone to learn that; the knowledge was simply within him; and, reflecting on that, he saw that the host was absent from him because the host was wholly fused with him; he was the host, the host was Jim McCulloch.
