The morning the sea turned to glass, Edda woke to total silence. No waves, no birds. From her window the whole harbor looked frozen smooth and shining. She sat at her desk and, almost without thinking, dipped her pen and inked a brand-new coastline onto a blank chart: cliffs, a bay, a row of sharp rocks. None of it was real. By the time the ink dried, a fisherman was pounding on her door, shouting that ships were sailing toward land that had never been there before.

Edda grabbed the chart and ran to the docks. Sure enough, three trading ships were turning toward the new bay she had drawn — straight at the rocks she'd inked. She had to warn them. She lit a lantern, swung it over her head, and shouted for the captains to turn back.

A young sailor on the nearest ship spotted Edda waving and rang the alarm bell. The crews scrambled. All three ships dropped anchor just short of the rocks, sails flapping, safe for now. The captains rowed ashore, furious, demanding to know who had put a deadly coast on their maps overnight.
