Once upon a time…

They said the fog there had weight. Each spring, villagers tied iron keys to their wrists, so the fog would not lift them. Marko, a river smuggler, laughed at this, but he tied one anyway when he took a hidden path to move salt past the border watch.

He had sworn, like the old shepherd from holy tales, to trust what he could not see. His child was sick, and a healer across the ridge waited for the salt payment. On the marsh road, the fog pressed like wet wool. Shapes stirred. Footsteps rang on water where there was no dock. A lantern blinked ahead, steady as a star.

Marko followed, counting ten paces, as the elders taught when the fog grew heavy. He reached a split—left to patrols, right to a sinking bridge. He set down his sack and raised his empty hands, as if offering what he loved most. The fog thinned.

The lantern belonged to no one. It hung over a stump. Beyond it, dry stones lined a new path. Marko crossed, delivered the salt, and returned with medicine. He kept the key tied on, and he no longer laughed.
