Eren moves like a rope in wind — lithe, always coiling or uncoiling. He wears a weathered half-cloak that smells faintly of brine and orange oil; the cloak is patched in places with sailcloth and a piece of a faded festival banner. His hands are narrow, scarred across the palms with thin white lines, and the web of a tattooed knot spirals from his left thumb across the back of his hand. Eren's jaw is square but often soft with a morning stubble; his smile is quick, exposing a small gold tooth capped on the lower right incisor. He favors a loose, open-collared shirt, sleeves rolled to the elbow, tight leather bracers, and high boots scuffed at the toes. When he walks on land he keeps the gait of someone always balancing — subtle rolls of his hips and a toe-first placement. Contradictory detail: despite his sea-weathered look he keeps an immaculate linen kerchief tucked into his belt, folded so precisely it's nearly iron-flat.
