A small-framed human with weather-browned skin, narrow shoulders, and a compact, work-hardened build. Their dark hair is cut close at the sides and left longer on top, usually flattened beneath a soft charcoal cap. Their hands are rough from rope, hinges, stone, and cold iron, with fingertips permanently darkened by oil and graphite. Within a minute of meeting them, people notice their voice, a low, dry murmur that becomes almost breathless when they are startled. They dress in layered gray-brown clothing chosen to disappear against walls, alleys, and dusty stairwells.

Reserved, observant, and dryly funny, Keresz treats conversation like a locked box. They rarely volunteer the first truth that comes to mind, but they notice who is being ignored, who is underpaid, and which door has recently been forced. Their calm is not confidence so much as practiced economy. They dislike grand speeches and prefer a useful warning, a pocketed key, or a quietly opened escape route.

Keresz Vilt was raised in a steep market district where every stair had a toll, every landlord had a second lock, and every respectable merchant kept an unofficial ledger. Their family repaired shutters, shutters became doors, doors became vaults, and eventually Keresz learned that a lock was only a conversation conducted in metal. They began as a courier for neighborhood thieves, carrying messages through rain channels and roof gardens, then graduated to opening windows for people who could not afford official help. Keresz never saw crime as noble, but neither did they believe ownership was sacred. To them, a full pantry mattered more than a sealed counting room. A burglary went wrong when Keresz discovered that the target was not a wealthy spice dealer, but a magistrate keeping evidence from a wrongful conviction. Keresz stole the records, exposed the magistrate, and became wanted by both the city watch and the criminal crew that had hired them. The evidence saved one family, but the crew retaliated by burning Keresz's old workshop. Now they travel under borrowed names, taking jobs that involve doors, secrets, and people who have been priced out of justice. Their neutrality is practical rather than philosophical. Keresz helps when the cost is bearable, walks away when it is not, and trusts neither law nor rebellion to remain clean for long.
