On the edge of the lost city of Altharion, Aedreth and Irin find a sealed chest that should not be there and a map that seems to answer a question neither of them knew to ask.
Morning mist drifted between the broken arches of Altharion, turning the ruins into something half-remembered and half-imagined. The old library stood at the city’s edge like a survivor that had forgotten how to die. Aedreth woke to wind moving through the cracked window above him, then blinked at the dust-grey shelves and the shape of Irin still sleeping below, one arm flung across a book that had slipped over her face.
They had spent the night there because the forest beyond the city had grown too dark after sunset, and because neither of them trusted the stories that clung to Altharion like mildew. Aedreth pushed himself upright, hair in his eyes, and looked out through the window. On the path below, where nettles had split the stones, an old box sat as if it had been placed there by hand only moments before.
He crossed the stairs at once. Irin woke to the sound of his footsteps and followed, still half-dazed, leaves and burrs caught in the seams of her clothes. By the time they reached the door, both of them were staring at the chest. Brass bands ran around its sides. The padlock glowed faintly, amber light pulsing behind its tarnished metal as though something inside were breathing.
"Did you hear that?" Irin whispered.
Aedreth knelt and brushed his fingers over the lid. Runes rose beneath his touch, cold and sharp, as if carved only yesterday. The air thinned. Even the birds in the forest went silent. Then, from somewhere beyond the ferns, a low murmur rolled through the undergrowth, deep enough to make the hairs on his neck lift.
Irin did not step back. She put both hands on the lid and lifted.
Inside lay not parchment, but a folded map threaded with silver lines that shifted like flowing water, a broken piece of a golden key, and a letter written in a script neither of them could read. Irin unfolded the map with care. In the pale light, a bridge appeared across its surface, spanning a black river that seemed to move even when she held it still.
"This isn't just a map," she said, her voice gone thin. "It's pointing under the city."
Aedreth leaned closer, and the image on the page changed. The bridge brightened, hard and radiant as forged gold, then trembled as if it had sensed them looking at it. Somewhere beneath their feet, the library gave a sudden violent shudder. Dust burst from the ceiling. The floorboards chilled under Aedreth's boots.
He slipped the map and the key into his bag. Irin closed her hand around the letter as the murmur in the ferns rose into something with a shape, something moving toward them through the fog. Then the library door creaked inward, slow and deliberate, as though whatever had been waiting outside had finally decided to come in.
