Herja is a woman around 5' 7" and that is her most constant quality.  She can appear as male or female but prefers the female form.  Her static Mask is a strikingly beautiful woman with long flowing red hair.  Her eye color, facial features, and hair color and length change can change to suit her whims.  Her Seeming is the same woman but with perfect, alabaster white skin and long flowing blood-red hair.

Her body is smooth, muscled perfection but she has no face.  If naked, one can see what appear to be fine cracks in the alabaster of her abdomen.  This is where Eyvind skewered her and she keeps it as a reminder of him and her years of endured suffering to bring him to justice.  Clothed she wears a variety of clothing but seems to like a particular green cloak in her Seeming.  Her shifting abilities allow her to assume a face or different Seeming as she wishes but only the Masks and Seemings of those she has met.
