A lean, weather-browned human with warm olive skin, narrow hazel eyes, and black hair cut short at the sides and tied back with a strip of sailcloth. Fine copper wire is braided through one lock of hair. Their fingers are stained with oil, pitch, and blue alchemical dye, and a thin scar crosses the left eyebrow. They wear practical scale mail beneath a salt-faded coat, with brass tools and tiny glass vials secured along the belt.

Curious, patient, and quietly protective. Sahra treats every strange object as a conversation waiting to happen and prefers repairing problems to arguing about them. They are generous with practical help, but their dry humor becomes sharp when someone wastes resources or endangers a crew through carelessness.

Sahra Sheshan was born in a crowded harbor district where every family measured time by tides, cargo bells, and the changing paint on the local ships. As a human child, Sahra learned quickly that a vessel was a machine made of smaller machines. Ropes, pulleys, bilge pumps, lanterns, and rudders all had temperaments, and a patient hand could coax almost anything back into service. An aging shipwright took notice of Sahra's talent and taught them to repair navigation instruments, distill lamp oils, and build small mechanical conveniences for sailors who had more coin than time. Sahra eventually became the deck engineer aboard the merchant vessel Starling's Mercy. During a storm that tore the ship from bow to stern, Sahra improvised a pressure valve from a compass housing and a silver spoon, saving the crew from a flooded engine compartment. The captain called it luck. Sahra called it proof that cleverness was most valuable when shared. Since then, Sahra has left the sea to seek lost designs, rare reagents, and the means to build devices that can keep ordinary people alive in extraordinary danger. They still sleep better when they can hear rigging creak overhead, and they never trust a calm horizon without checking the barometer.
