Bethony appears to be early 20's.  She has light brown hair and green eyes as well as freckles on her cheeks.  She wears simple clothing under a smithing apron, and carries a smithing hammer on her belt at all times.  She stinks of brimstone, and her skin and cloaking are usually peppered in a combination of soot and coal dust.  She's average height and weight.  Her body is stronger than an average woman, but lacks the refined muscles or skills of a lady-warrior.
