The Crawler was behind them. The words were behind them. It was just a submerged tunnel on a warm day. It was just a forest. It was just a place they were walking out of.
Ghost Bird and Grace did not talk much as they walked. There wasn’t much to say, such a world lay between them now. She knew that Grace did not consider her quite human, yet something about her must reassure the woman enough to keep traveling with her, to trust her when she said that something had changed beyond the climate, that they should head for the border and see what that something was. The scent of pine pollen clung to the air, rich and golden and ripe. The wrens and yellow warblers chased each other through the bushes and trees.
They encountered no one and the animals while not tame seemed somehow unwary. Not wary of them, anyway. Ghost Bird thought of Control, back there, in the tunnel. What had he found down below? Had he found the true Area X, or had his death been the catalyst for the change she had felt, that manifested all around them? Even now she could not see Control clearly, knew only that his absence was a loss, a sadness, to her. He had been there almost her entire life—the real, lived-in life she had now, not the one she had inherited. That still meant something.
At the moment he had gone through the door so far below, she had seen him and had felt the Crawler’s seekers fall away, the entire apparatus receding into the darkness after him. There had come a shuddering miniature earthquake, as the sides of the tunnel convulsed once, twice, and then were again still. Known that although nothing could be reversed, the director had been right: It could be changed, it could change, and that Control had added or subtracted something from an equation that was too complex for anyone to see the whole of. Perhaps the director had been right about the biologist, just not in the way she’d thought. The words from the wall still blazed across her thoughts, wrapped themselves around her like a shield.
Ghost Bird had walked up into the light to find Grace staring at her with fear, with suspicion, and she had smiled at Grace, had told her not to be afraid. Not to be afraid. Why be afraid of what you could not prevent? Did not want to prevent. Were they not evidence of survival? Were they not evidence of some kind? Both of them. There was nothing to warn anyone about. The world went on, even as it fell apart, changed irrevocably, became something strange and different.
They walked. They camped for the night. They walked again at first light, the world ablaze with sunrise and the awakening of the landscape around them. There were no soldiers, no suggestion of a ribbon stitching through the sky. The winter weather had lifted and it was hot, it was summer now in Area X.
The present moments elongated, once past still ponds and into the final miles. She lived in the present by dint of blistered feet and chafed ankles and biting flies drawn to the sweat on her ears or forehead and the parched feeling in her throat despite drinking water from her canteen. The sun had decided to lodge itself behind her eyes and shine out so that the inside of her head felt burned. Every beautiful thing that lay ahead she knew she had seen at least once behind her. Eternity found in the repetition of Grace’s steps, her sometimes halting steps, and the constant way the light gripped the ground and sent its heat back up at her.
“Do you think the checkpoints are still manned?” Grace asked.
Ghost Bird did not reply. The question made no sense, but enough humanity remained to her that she didn’t want to argue. The hegemony of what was real had been altered, or broken, forever. She would always know now the biologist’s position, near or far, a beacon somewhere in her mind, a connection never closed.
In the final miles to the old position of the border, the sun was so bright and hot that she felt a little delirious, even though she knew it was a mirage—she had water and was still hobbling through blisters and petty aches. How could the sun be so oppressive and yet the scene so unbearably beautiful?
“If we do make it through, what do we tell them?”
Ghost Bird doubted there would be a “them” to tell. She longed now for Rock Bay, wished to see it through the eyes of Area X, wondered how it might have changed, how it might have remained the same. This was really her only goal: to return to a place that had been like the island was to the biologist.
They reached where the old border had been, on the lip of the giant sinkhole. The white tents of the Southern Reach had turned dark green with mold and other organisms. The brick of the army outpost was half pulled down and sunken in as if some giant creature had attacked it. There were no soldiers, there were no checkpoints.
She bent down to tighten the laces on her boots, a velvet ant beside her foot. From what seemed like a great distance, she heard a scrambling huff from the lush vegetation of the sinkhole. For an instant, some odd, broad-shouldered marmot pushed its face through the reeds. Then saw her and hurriedly disappeared with a plop into the creek behind it—while she rose, amused.
“What is it?” Grace asked from behind her.
“Nothing. Nothing at all.”
Then she was walking again, laughing a bit, and everything was pressed out of her except a yearning for water and a clean shirt. Inexplicably, unaccountably happy, grinning even.
A day later, they reached the Southern Reach building. The swamp had crept up to the courtyard and seeped across the tiles, pushed up against the concrete steps leading inside. Storks and ibises had built nests on a roof that looked half caved in. The evidence of a fire that had burned itself out inside the building, somewhere near the science department, showed in scorch marks on the outer walls. From afar, they could see no signs of human life. No shadow of the people Grace had known there. Behind them lay the holding pond and the scrawny pine strung with lights, now two feet taller than when Ghost Bird had last seen it.
By mutual unspoken decision, they halted at the edge of the building. From there, a gash in the side showed them three floors of empty, debris-strewn rooms, and a greater darkness within. They stood for a moment, hidden by the trees, and peered at those remains.
Grace could not sense the way the building slowly took one breath and then another, the way it sighed. She could not sense the echo at the heart of the Southern Reach that told Ghost Bird that this place had built its own ecology, its own biosphere. To disturb that, to enter, would be a mistake. The time for expeditions was over.
They did not linger, look for survivors, or do any of the other usual or perhaps foolish things that they could have done.
But now came the crucible, now came the test.
“What if there is no world out there? Not as we know it? Or no way out to the world?” Grace saying this, while existing in that moment in a world that was so rich and full.
“We’ll know soon enough,” Ghost Bird said, and took Grace’s hand for a moment, squeezed it.
Something in Ghost Bird’s expression must have calmed her, for Grace smiled, said, “Yes, we will. We’ll know.” Between them, they might know more than any person still living on Earth.
It was just an ordinary day. Another ordinary summer day.
So they walked forward, throwing pebbles as they went, throwing pebbles to find the invisible outline of a border that might not exist anymore.
They walked for a long time, throwing pebbles at the air.
