Three friends notice the forest has gone strangely silent by day and unnervingly loud at night, until their search leads them toward a sound no one can explain.
In the heart of the Emerald Forest, where moss swallowed the paths and mist drifted between the trunks like breath, Lena, Antek, and Maks met every week to explore. They had fallen into an easy rhythm over the years: Lena listened for birds and noticed what others missed, Antek could read the ground like a map, and Maks knew the plants, roots, and hidden clearings better than anyone.
That week, though, the forest felt wrong.
The squirrels were vanishing into the branches and staying there for hours, as if something below had driven them up. Deer kept to the thickest cover, their ears twitching at every sound. Even the owls had started calling before sunset, sharp and restless, like warnings nobody understood. And after dark, just when the last light bled out of the trees, a metallic clatter rose from deep inside the forest. It came in a steady rhythm, echoing between the trunks, too regular to be the wind and too strange to ignore.
"Maybe it's an old fence," Maks said that morning, but he did not sound convinced.
Lena stopped beside a sapling and turned her head, listening. "Birds are avoiding the west side," she said quietly. "They all changed direction at once."
Antek crouched near the mud at the edge of the path. After a moment, he looked up with a frown. "And something heavy passed here last night. Not a deer. Not a boar either."
By noon they had packed flashlights, notebooks, and the battered night-vision goggles Antek had borrowed from his grandfather. They followed the trail deeper than they ever had before, under branches so tangled they seemed stitched together overhead. Broken fern stems marked the way. Strange scratch marks striped the bark. Once, Lena found a nest lying on the ground, empty and cold, as if it had been dropped in a hurry.
Then a black raven burst out of the undergrowth so suddenly that all three of them jumped back. It landed on a low branch, tilted its head, and dropped a single feather at Lena's feet.
She stared. The feather was pale green, almost glowing against the dark leaves.
"Ravens don't have feathers like that," she whispered.
Before anyone could answer, the metallic sound rang out again. Louder this time. Closer.
The raven snapped its wings open and vanished into the trees. The three friends stood frozen, staring into the thicket ahead, where the broken branches seemed to part around a narrow opening they had not seen a second ago. From somewhere inside it came one more sound, so close now that it made Maks grip his flashlight with both hands.
Something was waiting in the clearing.
