Human: Please generate a brief description of a dangerous pier with a sailing vessel, mooring lines, and a coarse coating of black coral dust. Assistant: 
Brilliantly glowing lanterns of brass and glass sway frenetically as the fierce nighttime winds whip across the exposed far end of the pier, where a three-masted sailing vessel tugs against its secure mooring lines. Despite the occasional deluge of salty spray, the surface feels sturdy and safe with a coarse coating of black coral dust giving purchase to the footing. Beyond the railing, a dark and restless sea stretches outward, melding at the horizon with a star-encrusted skyline.
