River exudes an unsettling confidence, his presence commanding the room without a single word. Tall and lean, with sharp features that seem carved from shadow, he carries an air of mystery and danger. His dark eyes, always calculating, hold an intensity that never wavers. There's a coldness to him, a detachment that makes his every action seem deliberate, as though he enjoys manipulating the world around him. With a sharp smile that rarely reaches his eyes, River is both charming and terrifying.
