They dove together into a pool of calm below a waterfall that should not have been there. The water folded around them and let them through into a narrow seam of sea lit with an unworldly phosphorescence. Roads of tide—actual ribbons of rippling water—arced like bridges between phantom isles. At the center, a small stone rose like a fist from the water; upon it sat a shell the color of storm glass and inside the shell a small shimmering heart carved of drift-wood and mother-of-pearl—the Heart of Tiderun.

That night Jardena walked the cliffs until the moon hung like a pale coin. She opened the chest in her private room. Inside, beneath a scrap of leather, sat a small, blackened key and a strip of sea-glass engraved with the same constellation as the maps. When she pressed the glass to the blue rose, the petals trembled and the lights of the lighthouse through the glass refracted while a tide-song hummed in her ears as if the sea were singing from under the floorboards.

The captain lowered his gaze. "We were paid to find the chest," he said. "Paid well. But maps—my employer said the maps were trouble."

"People are missing," Jardena said. "Old promises were broken. Your maps involve Halmar. Why?"

In the hold she found not contraband spices or stolen bolts of cloth, but maps—stacks of them, folded in vellum and ink-stamped with a constellation she had only ever seen in her grandmother's stories. The maps detailed islands that weren't on any current charts, star-roads where tides climbed higher than cliffs, and a single line that ran like a knot through each page: the name Jardena, written in an unfamiliar hand. At the bottom of the stack lay a small, tattered journal, and inside the first page, a single line: For Jardena of Halmar — return what was taken.

"Who paid?" she asked.

Despite the strength she projected, Jardena kept a private room above the lighthouse where she tended a small, unlikely garden under glass. Here, away from the wind and the town’s gossip, she grew rare sea herbs and a single blue rose—a stubborn thing that refused to bloom unless tended exactly at midnight under the light of a waning moon. She smiled at the rose more than anyone else; plants did not bargain or lie.
