Phantom is a lean, dark-plated warforged with matte charcoal armor, narrow silver eyes, and a weathered cloak stitched from mismatched scraps of canvas. His face is angular and expressionless, except for a faint blue glow beneath the seams of his jaw. A longbow rests across his back, two shortswords hang at his hips, and small strips of colored cloth tied around his left wrist mark places where he has slept safely.

Quiet, observant, and intensely practical, Phantom speaks in short statements and remembers details that others overlook. He rarely expresses affection directly, instead repairing equipment, standing watch, or leaving food where someone will find it. Though he presents himself as emotionless, he is fascinated by small signs of life, especially birdsong, children's laughter, and the changing patterns of rain.

Phantom was built for a war that ended before he understood what war was. His first clear memory is standing beneath a rain-slick awning while a group of abandoned children argued over whether he was a person, a machine, or something worth selling. He chose the name Phantom after learning that the city forgot people who did not make noise. The children taught him how to sleep in abandoned lofts, how to read a guard's footsteps, and how to disappear into crowds. In return, Phantom watched the alleys at night and used his strange endurance to keep predators away from the smallest children. When the children scattered, Phantom became a hunter of the city margins. He tracked thieves, escaped animals, fugitives, and occasionally missing children, accepting payment in food, information, or spare parts. His instincts led him beyond the walls and into the surrounding forests, where he learned to read broken branches, cold ash, and animal trails. He now travels as a ranger, searching for the people who built him and for any surviving record of the children who first gave him a purpose. He does not seek glory or revenge. He simply follows the trail, one quiet step at a time.
