Jaxen is a lean young man with sharp features and a mess of dark hair that constantly falls over his gray eyes. He wears fitted dark leathers that show signs of heavy wear and a charcoal gray cloak that allows him to vanish into shadows. He has a few small scars on his knuckles and chin, souvenirs from a childhood spent in back alleys.

Jaxen is perpetually observant, treating every social interaction like a game of cards where he is counting the deck. He is cautious with his trust but surprisingly witty once the ice is broken. He believes that everything has a price and everyone has a secret.

Jaxen was orphaned in the sprawl of a massive merchant city, left to the mercy of the 'Grime-Walkers', a local street gang that specialized in burglary and intelligence. He was trained from the moment he could walk to be silent, invisible, and efficient. The gang was his only family, though they taught him that the only person he could truly rely on was himself. He spent his youth navigating the rafters of noble manors and the lightless tunnels of the sewers, perfecting the art of the heist. Eventually, the gang was betrayed by one of its own. Jaxen was one of the few to escape the city watch's raid. Now he operates as a freelance specialist, taking contracts that require a gentle touch and a silent step. He carries the lessons of the street with him, using his past as a shield against a world that has never given him anything for free.
