They had come from different worlds. They spoke different languages. What they had shared had been at least partly illusion. And yet, and yet, and yet… He took comfort in limping along the trail beside her, before her, behind her, thumping shoulders together or sharing moss they found. Beauty is only the beginning of terror, but just to have company, to share the news: there is a block of pink quartz. The seas look high. The wind is strong. And so the terror is staved off. Through black haze, beauty still perceived.
The ridge became deeply serrated, peaks like the teeth of a crude saw, making progress nearly impossible. Why go on, Thel thought one morning, but then the swimmer started off, scrambling up a broken cliff, using all fours, and he followed. “Why” was one of the questions that had gone away. Pain clouded his vision. A bird’s nest gave them a feast. A storm left them soaked and cold. Near its end lightning shattered the peak above them, leaving their ears blasted, their nerves tingling, the strong smell of ozone in the wind. The shock of it seemed to invigorate the swimmer and she led all the next day with a will, over peak after peak, and down into deep cols. Their bodies were continuing to devolve, and only this allowed them to continue; now she could slither up rock, and how he could cling!
Then late one afternoon they made their way slowly over a hump of granite, and on the other side of it the peninsula dropped off into the sea, and came to an end.
It did so in a sheer clean prow, so smooth that it had to have been crafted. Also there was a smoothed waist-high wall to each side, bowing in and meeting at an angle, at the final point of the ridge. They walked out to the meeting of the two walls and leaned out to look. Clearly in some past age some civilization had come here and cut the granite cape smooth, creating two polished curving walls that came together in a straight edge which dropped to the sea in a single swoop, a clean crease like the bow line of a great ship. It was a drop, Thel estimated, of about ten thousand feet.
They walked around on this last forecastle, south to north and back again, looking down at the workmanship of the two cliffsides. The polished granite was a flecked color, an infinitely dense mix of feldspar, quartz, and hornblende, so that just below them it appeared speckled like a trout, while farther down it seemed only a pinkish brown, like a kind of marble. Stones that Thel dropped over the walls skipped down and disappeared, and he never even saw them mar the dark blue of the sea.
It was nearly sunset. The swimmer wandered about, collecting rocks and laying them on the triangular block where the two walls met, the outermost point. Thel asked what she was doing and she smiled, gesturing at the mirror bag. “This must be the place, yes?”
Thel shivered, looked around. They could see for many, many miles, and the horizon was a clear sharp line between sea and sky; but the air was somehow thick, the sunlight in it dark. He took the mirror from the bag and put it on the final tip of the wall, held it in place with the rocks the swimmer had gathered. The eastern sky was full of the setting sun’s yellow, and the mirror’s surface glowed like a lens, as if scooping up all the beautiful sunlight in the world and flinging it westward, in a single coherent beam. “But what will we do?” Thel asked.
The swimmer stretched and stood on her hind legs, pointing with one foreleg at the glass. “At the last moment of sunset we will leap through,” she said happily. But she was a sea creature, and this was, perhaps, a return to the sea; while he was a tree creature, in a land without trees, and he was afraid. And yet, and yet…
They sat on the wall and watched the sunset, the light leaking out of the sky, the wind rustling the great space of dusk and the sea. The incredible furnace of the sun fountained light even as it sank into the ocean, which gleamed like a cut polished stone. Overhead a windhover fluttered in place, slicing the wind and sideslipping, and seeing it Thel was calmed. Whatever happened, yes, but more than that there was a kind of glory in it, to fling themselves Out into the spaces they breathed, if only for one last dive or flight. The sun pared to a yellow line on the sea, and the sky darkened still; the mirror surface, still a kind of lens gathering sunlight, glowed a rich yellow that greened and greened as the sun’s rays bent around the curve of the globe, prisming under gravity’s pull. Out on the horizon the brilliant yellow line contracted in from both sides, greening all the while, until at last it was nothing but a single point of the most intense emerald light: the green flash, the sun’s farewell, and the mirror’s surface was flush with green light, the whole circle a pool of glowing green, and the swimmer’s paw caught Thel by the arm and pulled him to his feet. Overhead the kestrel tipped and dove, down in a curving stoop, shooting by them and falling faster until it burst to white, like a meteor streaking over the sea; and with a cry the swimmer leaped forward and jumped through the mirror, and Thel followed fast on her heels.
