Krey is a lean male Tabaxi with charcoal-gray fur, pale silver markings around his muzzle, and long limbs that give him a spring-loaded, prowling gait. He moves with restless precision, frequently shifting his weight from one foot to the other as though listening for a distant sound. His broad feline grin reveals one noticeably prominent lower canine, especially when he laughs or tastes unfamiliar food. He wears practical scale mail beneath a weather-stained cloak, with tinker's tools and salvaged metal charms hanging from his belt.

Krey is curious, practical, and unfailingly willing to help someone who is stranded or overlooked. He treats broken objects as puzzles rather than trash and speaks to his tools as if they were stubborn traveling companions. He is friendly but easily distracted by mechanisms, unfamiliar scents, and anything that appears to have a hidden compartment.

Krey was born among a traveling Tabaxi hunting caravan that followed old game trails through forests, highlands, and forgotten roads. He was never the strongest hunter or the most graceful climber, but he became fascinated by the small mechanisms his people used to repair carts, traps, cooking gear, and musical instruments. While other kittens collected feathers and polished stones, Krey collected bent nails, broken buckles, and bits of abandoned clockwork, patiently rebuilding them into devices that were usually useful and occasionally alarming. During one harsh migration, a collapsed bridge stranded several members of the caravan on the far side of a flooded ravine. Krey improvised a system of pulleys, braces, and counterweights from travel equipment, allowing everyone to cross safely. The success convinced him that the world was full of problems waiting for clever hands rather than powerful ones. He left the caravan with its blessing, carrying a battered set of tools and a promise to return with stories, maps, and inventions that could make the next journey safer. As an Outlander and an aspiring artificer, Krey now wanders from settlement to settlement, repairing what others discard and quietly searching for the lost techniques of an ancient maker whose fragments he found along the road.
