Kierahn is a young looking man, in his late teens, with long black hair that tends to hang in front of his face.  His clothes vary dependent on the place he is, but within Avalon, he is usually dressed in a dark purple kimono with black highlights.  His eyes are a grey-blue, and seemingly always attentive as he scans the area for potential threats, his facial features sharp and lean.  Standing at 6'4", he is a tall figure, muscular, but with a small waist and agile movements.
