The light came in low and yellow, catching the dust motes in the beam of the theodolite. I had counted the hours since the last reading: four. Four hours of stillness, of holding the instrument steady against the tremor in my hands. The wind had dropped, which was wrong. In the highlands, the wind never drops; it only changes its mind. I checked the level bubble. It sat centered, a small green eye staring up at me. I wanted the map finished before the snow came. That was the contract. That was the wage. If the passes closed, the survey failed, and the firm would not pay for a blank sheet of paper. I reached for the flask Thomas had pressed into my palm an hour ago. It was warm, as if he had held it for a long time. The glass was thin, the liquid inside a dark, viscous amber. Opium tincture. I had not taken such a thing in years, not since the days I thought I could buy back time with pain. But my hands shook too much to read the scale. I uncorked it. The smell was sharp, medicinal, and deeply wrong. I drank. The taste coated my tongue, bitter and thick, settling in the pit of my stomach like a stone.

Thomas stood by the ridge, his face turned away from the wind. He was a good man, steady, quiet, the kind of man who did not ask for raises and did not complain about the cold. But his eyes were hollow, the skin beneath them dark and bruised. He whispered something. I leaned in. He said the mountain was eating us. I laughed, a dry, cracking sound. I told him the mountain was stone and ice, and that stone and ice did not eat. He did not answer. He turned and walked down the slope, his boots crunching on the scree. I waited for him to return. I waited until the light shifted from yellow to a pale, bruised grey. He did not come back.

I looked at the ridge. There were two pairs of boots. One pair was mine. The other was empty, the laces still tied, the soles caked in mud. Thomas had left them. He had fled to the lower village, down the pale path that wound through the mist. I felt a surge of anger, hot and sharp. He had abandoned his post. He had abandoned the work. But then the anger cooled, replaced by a strange, hollow clarity. He had not run from fear. He had run from me. He had seen something in my face that he could not fix. He believed I was already gone, a ghost haunting the stone, and he had saved himself from the company of the dead. I packed my bag. The instruments were heavy, pressing against my spine, a physical weight that anchored me to the earth. I shouldered the pack. I began the descent.

The air in the valley was thin and cold. It bit at my lungs, a physical pain that kept me awake. The fog was thick here, a white wall that swallowed the trees. I walked by the feel of the ground, by the slope of the earth under my boots. After an hour, I heard a voice. It was low, rough, like gravel in a tin. I turned. A shepherd stood by a stone wall, his face hidden by a heavy wool cap. He looked at me. He did not speak at first. He just looked, his eyes narrowing in the gloom. Then he said, You look like him. My stomach dropped. I asked who. He said, Your father. The name hit me like a physical blow. My father had vanished on this same path twenty years ago. I had been a boy then, standing at the edge of the ridge, watching the mist take him. I had not seen his face. I had only seen the wool of his coat, the same grey as the clouds. I am not just a man, I thought. I am a recurrence. The cycle of disappearance is in my blood.

I walked on. The path narrowed. I reached the village tavern. It was a low stone building, half-buried in the hillside. The door was open. Inside, it was dark and smelled of wet wool and old wood. An old man sat by the fire. His eyes were milky, blind to the world but sharp to the scent of the living. He did not ask for my name. He did not ask for payment. He pushed a bowl of broth toward me. It was simple, thin, with a few slices of carrot and a strip of beef. I ate. It was hot, and the heat spread through my chest, chasing the cold from my bones. The old man spoke. His voice was soft, barely a whisper. He said my father had come here, twenty years ago. He said my father had drunk the same broth. He said my father had walked back up the mountain to die. I set the bowl down. The broth was still warm, a small pool of life in the dark. I looked at the window. The glass was dark, reflecting my own face. It was pale, hollow, the features stretched by the opium in my blood. I was the echo. The walls of the tavern seemed to breathe, expanding and contracting with the rhythm of the fire. I stood up. I left the bowl on the table. I did not take the change he left on the counter. I walked out into the night.

The snow had begun to fall. It was fine, dry, and silent. I climbed back to the ridge. The theodolite was still there, a dark shape against the white. I set it up one last time. I did not measure the land. I measured my own distance from the edge. I looked through the lens. The world was a grid of lines, a web of geometry that held nothing. The wind howled, a low, continuous moan that sounded like a name being called. I realized the map was not of the terrain. It was of my own descent. The lines I drew were the veins of my own unraveling. I saw a dark object in the snow. I walked over to it. It was a leather journal. Thomas’s. I opened it. The pages were damp, the ink blurred. The last entry was dated that morning. He wrote that he saw me walking into the white, smiling. He thought I had found peace. I had not. I had found the trap. The opium had turned my fear into a calm, deadly acceptance. I was not fighting the mountain. I was feeding it.

I climbed to the highest point. The sun was setting, turning the snow to a deep, arterial red. The light was dying, bleeding out of the sky. I took out the vial. It was empty. I had drunk it all. I was not high. I was clear. The clarity was terrible. I saw the path below, pale and winding, a ribbon of white leading down to the valley. I understood now. The cycle was not escape. It was return. I was the pale path itself. I sat on the rock. The cold seeped into my bones, a slow, steady invasion. I did not shiver. I watched the stars emerge, one by one, piercing the dark. They were cold, distant, and indifferent. I closed my eyes. The last thing I felt was the weight of the stone beneath me, solid and eternal. I am part of the mountain now. The map is complete.
