Description
A middle-aged man with a slender build who stands half a head taller than his much broader companions, his long thin hands visibly rubbing across his head when he removes his hat. His face appears haggard and worn from drinking cheap beer and the accumulated years, causing him to stand less steady on his feet than expected after a night of heavy consumption with bottles littering the table. As a Ceres station detective in the low-gravity Belt, he has the pale skin and lanky physique typical of humans adapted to space, projecting a world-weary and experienced air with sharp but tired features beneath his hat.
