Being of average height and slight build, with auburn hair framing a youthful and fair complexioned handsome  face, and dressed in clothing of common style and fabrics, only that he wears a scholarly robe, open to the elements most times, and piercing green eyes that seem to have seen more than anyone his apparent age should ever have to see, Jervis could disappear easily into a crowd.  But, he does not.  He leaves an impression where ever he goes.
Whether it's because of his habit of helping people in need, or the strange things he says and does sometimes, people seem to tend to remember him.
