Blind sound engineer Cohen works with sonar feedback and modeling software, bringing a distinctive, technically skilled perspective to the crew. His serenity holds even in the disorienting conditions of the ship, though it can break into a blunt, startling remark. He remains a quietly capable presence amid the group’s mounting tension.
Description
Cohen has a pale face and a composed, open expression, with black glasses covering the upper part of his face and concealing his eyes. His lips often settle into a faintly pursed frown, lending his stillness a thoughtful edge. He is blind and works with sound and modeling tools, giving his presence an attentive, measured quality. No details are provided about his hair, height, or build.
