Asher Willbourne has crystal blue eyes and black hair that he shaves regularly so that it is rarely more than a stubble. His skin is tanned from many hours spent toiling in the sun. While not physically unattractive, his stoic demeanor and lack of empathy dull his charisma. He wears the short, black, hooded robe of his former order, calf-length breeches and plain sandals that lash around his ankles.

At first glance he is not an intimidating figure; his build is slight and sinewy and his weapons (2 Kamas) are tucked unobtrusively into the folds of the wide sash he wears around his waist. He moves with a precision and economy of movement that match his serious, "let's get straight to business" expression.
