Nevyn is a lean male tabaxi with tawny-gold fur patterned in dark russet stripes, a long ringed tail, and alert green eyes. He stands with his weight balanced on the balls of his feet, as if every conversation might become a chase. His fur is carefully groomed around the face and ears, while the rest of him is kept practical and slightly weather-stained. He wears a well-fitted leather jerkin beneath a patched charcoal cloak, with a rapier at his hip and thieves' tools arranged in neat, obsessive rows inside his belt pouch.

Nevyn is curious, adaptable, and determined to be useful, though he disguises his insecurity beneath dry observations and restless competence. He eagerly learns almost any skill placed in front of him, then becomes defensive when someone suggests he is not good enough to use it professionally. He has a soft spot for outsiders, strays, and anyone being ignored by a crowd.

Nevyn was raised among the market roofs and narrow lanes of a crowded port city, where being a tabaxi made him memorable even when he desperately wanted to be overlooked. He had a talent for nearly everything he tried. He learned letters from a retired clerk, knots from a dockhand, knife work from a street performer, and the basics of accounting from a pawnbroker. When he attempted to make any of these skills into a respectable profession, he was rejected. The guilds called him unreliable, the performers called him too awkward, and the merchants called him too strange. One by one, every door closed in his face. The final rejection came from the city watch, who dismissed him after a failed attempt to join as a records clerk. Nevyn had uncovered evidence that a prominent official was stealing from the poor, but his warning was ignored and his questions made him enemies. With no trade willing to claim him, he returned to the streets, where his quick hands, sharp eyes, and knowledge of hidden routes finally became useful. He began carrying messages, opening locked doors, and taking from people who had more than enough. He tells himself he chose the shadows, but the truth is that the shadows were the first place that made room for him. Now he travels as an adventurer, hoping to prove that being unwanted by every profession does not mean he is useless.
