Three young Vikings slip into the fog and discover a strange dragon-prowed boat no one in Stormheim has ever seen.
In the far north, where black water met knife-edged rock and the fjords vanished into silver mist, stood the settlement of Stormheim. By day it was all salt, smoke, and hammer blows from the smithies; by night it crouched beneath the northern lights like a ship tied to the shore. The elders said the sea had a memory. Leif believed it. He only wished the sea would stop hiding its best secrets.
At fifteen, he had already earned a reputation for doing things before thinking them through. He could outclimb the boys his age, outrun most of them, and talk his way out of trouble almost as often as he caused it. Yrsa, one year older and far less patient, had long since learned to keep him in sight. She carried her own axe proudly and her opinions even prouder. Ivar, quiet as snow settling on a shield, usually let the two of them argue while he watched, listened, and noticed what others missed. He could read runes, puzzle out old markings, and make sense of things that looked impossible to everyone else.
That morning, a fog rolled in from the open sea so thick that the bay disappeared before breakfast. The ravens refused to fly over the water, circling instead above the palisade with uneasy cries. Even the gulls stayed ashore. By noon, the adults had tightened the gate, warned the children to stay inside the walls, and gone back to their work with the tense faces people wore when the weather felt wrong.
Leif was not built for staying inside walls.
He found Yrsa and Ivar near the drying racks behind the longhouse, where the fog pressed close enough to dampen the wood. "If we spend our whole lives waiting for the fog to lift, we'll never learn what it is hiding," he said, grinning as if that made perfect sense.
Yrsa folded her arms. "Or we could stay alive and let the grown-ups do the foolish part."
"They'll never see us," Leif said. He tipped his head toward the beach. "Not if we're quick."
Ivar looked toward the bay, where the water had turned pale and featureless. For a moment he said nothing at all. Then he reached into his belt pouch and pulled out a small bone token carved with a spiral. "If we go," he said, "we go carefully. The old stories say fog can carry things it shouldn't."
That was all the warning Leif needed to be interested.
The three of them slipped through the side gate while the watchman was arguing with a fisherman over a torn net. They found Leif's old rowing boat half-hidden beneath a canvas sheet and pushed it into the water. The sea received them without a sound. No waves slapped the hull. No seabirds called overhead. Even their oars seemed to move through wool.
They rowed deeper into the mist until Stormheim was only a dim shape behind them, then nothing at all.
At first there was only silence and the soft drip of water from the oars. Then a dark shape rose ahead of them, jagged against the whiteness. Not a rock. Not a seal-slicker. A narrow promontory they had never seen before, thrusting out from the fog like the prow of some buried giant.
And on the stones beside it sat a boat.
It was longer and leaner than any craft from Stormheim, its planks dark with age and its hull streaked with pale green growth. Strange carved patterns ran along the sides, twisting in and out of one another so tightly they made Leif's eyes ache. At the stern stood a dragon carved from weathered wood, its eyes set with something green and glassy that caught the faint light above the mist. The shape should have looked ruined. Instead it looked watchful.
Yrsa's voice dropped to a whisper. "Whose boat is that?"
Ivar was already staring at the carvings. His face had gone still in the way it did when he found a rune he could not read. "I have never seen marks like these," he said. "Not in any of the sagas. Not on any stone."
Leif tied their boat to a slick post and stepped onto the shore before either of them could stop him. The gravel shifted under his boots. The strange vessel loomed above him, silent and waiting, as if it had drifted through the fog just for them. He ran a hand over the hull. The wood was cold enough to sting.
"There could be treasure inside," he said, though the words came out thinner than he meant them to.
"Or a curse," Yrsa muttered.
Leif gave her a sideways grin, but his pulse had already started to race. He climbed aboard and ducked beneath the low edge of the deck. Ivar followed more slowly, eyes fixed on the runes, while Yrsa came last, one hand near her axe and her gaze never leaving the mist behind them.
Below deck, the air smelled of old salt, tar, and something else Leif could not name. Coils of rope lay in shadow. Crates were lashed tight with rope gone brittle with age. A thin line of pale light slipped through the boards overhead, enough to show a shape carved into the far wall - a mark like an eye, or a whirlpool, or both.
Leif took one step forward.
The whole boat gave a low, sudden shudder.
Yrsa went rigid. Ivar drew a sharp breath. Somewhere beneath the planks, hidden in the dark, something moved.
Then came a quiet metallic rasp from under the deck.
