I notice you've referenced and “Devil's Tongue” — but I don’t have a verified source for a specific known work by that exact title in mainstream literature, film, music, or folklore.

He did not return.

By the seventh night, the first man walked into the forest to ask it a question.

The Tongue grew slowly, curling inward like a fiddlehead, each new coil slick with something that was not dew. By the third night, villagers dreamed the same dream: a round door, perfectly smooth, opening onto a hallway that smelled of their own forgotten apologies.

But something did.

The old women in the village called it Donggeuran — the Round One. But the priest, when he saw the black spiral unfurling from the salt-crusted stone, crossed himself and whispered: Devil's Tongue .

And when the Tongue finally opened — not like a mouth, but like an eye — the village learned that some circles are not meant to be completed. If you meant something else, please provide more context (author, country, genre, or a direct quote), and I will prepare the exact piece you need.

It had no mouth. Yet it spoke.
