The deck heaved under Kara's boots, salt crusting her lips as thunder cracked the sky. She was the only one left—crew washed away hours ago in the squall. Fingers raw, she snagged the floating chest just before a wave could claim it.

Prying the rusted latch, she gasped. Inside, nestled in kelp, sat a brass compass unlike any she'd seen. Its needle whirled counterclockwise, ignoring the gale's chaos, locking onto a point directly below the ship. 'What madness,' she muttered, but her father's voice echoed in her mind: 'Follow the pull, girl. Seas hide fortunes.'

Dawn broke gray and oily. Kara adjusted the sails, the sloop groaning toward the compass's invisible call. Gulls wheeled silent overhead, their cries swallowed by thickening fog that smelled of brine and rot. The water deepened to ink-black, fish scattering in panicked schools.

A shiver ran up her spine—not from cold, but the hum. Low at first, like whale song, then words in a tongue she half-knew from old port tales. Her pulse hammered; sweat beaded despite the chill. 'Not real,' she whispered, gripping the wheel till knuckles blanched.

The fog parted like torn silk. Jagged reefs thrust from the sea, crowned with coral that pulsed faint green. The compass needle steadied, quivering toward a cavern mouth yawning in the rock face. Kara's breath caught—inside, shadows shifted, gold glints flashing.

Tying off the line, she dove into the shallows, compass clutched tight. Water pressed cold and heavy, bubbles trailing her kicks. Surfacing in the cave, bioluminescent vines lit walls etched with maps of stars she'd never charted. At the center: a pedestal, holding a second chest, larger, sealed with barnacles.

Her hands trembled as she approached. The hum swelled to a chorus, vibrating in her chest—promising riches, or ruin? The compass burned hot in her palm. She reached for the seal.
