Jack is a bit on the short and slender side for the average man.  At just over 165cm (5'5") with a shock of stark white hair, eyes the color of a brooding storm and sharp, angular features. Jack tends to stand out a bit in a crowd.  He has a pleasant voice with a mild, indeterminate accent that sounds vaguely Germanic or Eastern European.

  He dresses more formally than casual, preferring more layers than are usually called for.  Suits with vest, coat and overcoat for example.  His tastes run a bit on the retro side, with Victorian and baroque styles on the upswing, but he's not above wearing a hoodie and jeans if he has to blend in.  He prefers clothes in blues, whites, greys and metallics with sharp and severe, yet stylish, cuts.
