Kezk Vargl is a compact kobold with rust-red scales, a pale tan muzzle, and broad ears that twitch toward every unfamiliar sound. He stands with a sailor's rolling balance even on solid ground, though his habit of leaning too close when examining tools makes him seem larger and more intrusive than he is. A soot-darkened leather apron hangs over his worn sailor's clothes, crowded with tiny brass instruments, wire spools, shell fragments, and carefully labeled cork vials. His voice is quick, dry, and surprisingly resonant for his size. When calm, he speaks in clipped observations. When rattled, his breathing becomes audible little clicks between words.

Kezk is intensely observant, practical, and eager to prove that clever hands matter more than imposing size. He treats every lock, knot, engine, and weapon as if it has a personality that can be understood with enough patience. Around strangers he is wary but inquisitive, asking blunt questions and standing much too close while studying their gear. He shows affection by repairing things without permission and offering brutally specific safety advice.

Kezk Vargl was hatched in a cramped coastal warren beneath an abandoned lighthouse, where his clutch survived by scavenging wreckage from the reefs. While the other kobolds prized blades, traps, and anything that could be traded for food, Kezk became fascinated by the objects that still worked after storms had broken everything else. He learned to mend lantern shutters, splice snapped winch lines, and coax life from drowned clockwork by listening to the changes in a mechanism's sound. A merchant vessel eventually took him on as a deckhand after he repaired its jammed bilge pump using a fishhook, whale-bone pin, and a strip of sailcloth. Kezk spent several years at sea, becoming a competent sailor and an obsessive tinkerer. He now travels with a battered leather tool roll and a half-finished device he calls the Tide-Speaker, a brass-and-coral instrument meant to predict dangerous changes in wind and water. He left his last ship after discovering that its captain knowingly sailed through waters marked by his device as deadly. Kezk saved most of the crew, but the ship and several friends were lost. He has sworn that the Tide-Speaker will one day become accurate enough that no captain can dismiss a warning simply because it came from a kobold.
