The Last Sunset of Porto Alegre

Six months in the grey, rain-slicked streets of Invercargill had leached the colour from my soul. The constant wind, the low sky, the endless flatness—it was a slow suffocation. So when my brother Conor, stationed in Cape Town, got a work trip to Brazil and offered to bring me along, I jumped at it. My partner, Aiden, was less thrilled. ‘Brazil? Now? With your brother?’ he’d said, his voice tight with unease. ‘There’s something off about that place. The stories…’ I’d laughed it off, packed my bags, and within a week I was on a plane, leaving Invercargill’s greyness behind.

The flight was long, and the stopover in Santiago didn’t help. I looked out the window as we descended, and the Andes rose like skeletal fingers through the clouds. A sudden, irrational dread gripped me, a certainty that I was making a mistake. I shook it off, blaming the turbulence and the exhaustion.

At São Paulo’s Guarulhos airport, I found Conor. He looked well, but there was a haunted edge to his eyes, a tension in his smile. ‘Glad you made it,’ he said, hugging me tightly. ‘I’ve hired a car. We’re heading to a coastal town called Porto Alegre—no, not the big city, a smaller place, an hour south. It’s beautiful, you’ll love it.’

We drove for hours, the urban sprawl giving way to winding roads thick with jungle. The air grew heavier, more humid, and the light turned a sickly yellow as the afternoon wore on. Conor was quiet, offering only monosyllabic answers when I asked about his work or our father’s estate, which he’d been handling. He’d been in Brazil for three months, and he’d been different ever since.

We arrived at a small village: a cluster of faded pastel houses, a church with a cracked bell tower, and a single, broad street leading to a dark, crashing sea. The beach was black sand, and the water looked like oil. The only hotel was a weathered colonial building with a sign that read ‘Pousada do Sol’. Conor got us a room with a balcony overlooking the ocean. As the sun set, the sky turned a bruised purple, and the water seemed to swallow the light, leaving no reflection.

That night, I had a dream. I was walking along the black shore, and the water was receding, exposing a vast, ancient structure beneath: a city of round, black stone domes, each with a single, unblinking eye etched into it. A low hum vibrated through the ground, and a voice, not in words but in pure emotion, whispered a name: ‘O Último Pôr do Sol.’ The Last Sunset. I woke with a jolt, my heart pounding, and found Conor standing at the window, staring out at the pitch-black ocean.

‘You felt it, didn’t you?’ he said without turning. ‘The pull.’

The next morning, the sun didn’t rise. The sky stayed a dull, ash grey, and the ocean was unnaturally still, like a sheet of glass. The locals, previously friendly, now avoided us, crossing the street when we approached. An old woman with leathery skin spat on the ground as Conor passed. ‘You bring ill omens,’ she hissed. ‘You should not have come.’

Conor didn’t seem surprised. He led me to a shack on the outskirts of the village, where a fisherman sat mending nets. He looked up, and his eyes were milky white, like cataracts. ‘The beach will open today,’ he said, his voice rasping. ‘It must be fed.’

‘What does that mean?’ I asked, but Conor grabbed my arm and pulled me away.

‘It’s the bargain,’ he said, his voice barely above a whisper. ‘Our father made it years ago, to save our mother. He gave something to the sea, to that thing under the sand. Now it’s time to repay the debt.’

‘What? No, that’s insane. Dad was a botanist. He died of a heart attack.’ But even as I said it, I remembered the strange, cylindrical object Dad had left in his will, wrapped in oilcloth, with instructions that Conor and I were to deliver it to a ‘dona at Pousada do Sol’. We’d dismissed it as senile rambling.

‘He didn’t die of a heart attack,’ Conor said, his eyes hollow. ‘He went into the ocean, and he didn’t come back. They found his heart, intact, on the beach. The rest of him… no one knows.’

I felt the world tilt. My father had drowned years ago, but the official report said heart attack. Conor was my anchor, him and Dad. And now Conor was telling me our family was tied to some eldritch horror in Brazil.

‘We have to leave,’ I said, my voice trembling. ‘Right now.’

Conor shook his head. ‘It’s too late. The bargain is set. When the sun doesn’t rise, the beach will open. And we have to be there. Or it will take everything.’

He handed me the oilcloth bundle from his backpack, and I unwrapped it. Inside was a smooth, obsidian sphere, about the size of a fist, engraved with the same single eye I’d seen in my dream. ‘It’s the key,’ he said. ‘We have to throw it into the center of the structure when it appears.’

‘And then what? It’s closed forever?’

Conor’s lips twitched. ‘Then we pray it’s enough.’

We walked to the beach as the grey morning stretched on, the sky never brightening. The tide was low, lower than I’d ever seen, and in the distance, the black sand began to bubble and shift, revealing the tops of the domes from my dream. The hum grew louder, a subsonic vibration that rattled my teeth. The villagers lined the shore, silent, their faces masks of dread.

The domes rose slowly, slick with brine, each one bearing a single, lidless eye that seemed to follow us. At the center of the circle of domes was a shallow basin, filled with black, viscous water. The hum became a chorus of voices, chanting words I didn’t understand but felt in my bones: ‘O Último Pôr do Sol.’

‘Now!’ Conor screamed, and I flung the sphere with all my might. It landed in the basin with a wet thunk, and the water began to churn. The eyes blinked simultaneously, and the hum rose to a deafening pitch, then cut off. Silence. The domes sank back into the sand, leaving only the black beach and the motionless sea.

I looked at Conor, expecting relief, but his face was contorted in pain. ‘It wasn’t enough,’ he gasped, and he collapsed onto the sand. His skin grew pale, then grey, and I watched, helpless, as his body withered and crumbled, turning to ash that blew away on a sudden, cold wind. The villagers moaned and moved away, leaving me alone on the shore, the sun forever dimmed.

I don’t know how long I stayed there. Hours? Days? The sky never changed, the sea never moved. Finally, I stumbled back to the pousada, and the old woman who owned it looked at me with pity. ‘You are lucky,’ she said. ‘You gave the sphere. The bargain is fulfilled for your line. But the Last Sunset has begun. It will spread, taking light from the world, until a new bargain is made.’

I left Brazil that night, the last flight out before the airport shut down. I returned to Invercargill, but it’s not the same. The greyness is there, but now it feels different, as if the world itself is fading. I haven’t told Aiden what happened. I can’t. But I know the truth: the sun will not rise again, not fully, not anywhere. And I have seen the last sunset. It was black, and it was hungry.
