Jackal is a lean, weathered human man with a narrow face, a crooked nose that has always been crooked, and watchful gray-brown eyes. He wears a badly fitted suit of chain mail over a faded charcoal shirt, with the left sleeve repeatedly patched in different shades of cloth. His boots are carefully oiled despite their cracked leather, and he keeps one old black scarf folded with almost ceremonial precision around his neck. When waiting, he leans forward with his weight on the balls of his feet, as though every quiet moment might suddenly become a chase.

Jackal is simple, blunt, and cold in ordinary conversation. He prefers direct instructions, familiar routines, and problems that can be solved with his hands. He rarely laughs, but he is fiercely alert when danger appears. Underneath his hard temper is a practical kind of loyalty. Once he decides someone is his person, he protects them without asking whether they deserve it.

Jackal grew up in the back rooms and service alleys of a crowded city, where he learned early that locks were easier to understand than people. He was never clever enough to become a planner or a forger, but he was steady with his hands, quick with a knife, and willing to keep moving when everyone else panicked. A local gang used him as a runner, lookout, and debt collector. His jobs were simple, and Jackal liked them that way. Get the package. Stand by the door. Hit the man who reaches for a weapon. Do not ask why. The gang eventually sold him out to protect a more valuable member. Jackal escaped custody during a prison transfer by breaking a guard's nose with a chain and running into the rain. Since then, he has worked as a mercenary and occasional thief, taking jobs that offer clear instructions and immediate payment. He became a fighter because fighting was the one trade where his instincts mattered more than his judgment. He still carries the gang's old black scarf, not out of loyalty, but because it was the first thing he ever owned that someone had given him without asking for money in return.
