Standing 5'11, Jace has brown eyes that look a dark amber in sunlight. His natural hair colour is a dark brown, as seen with his beard colour. He keeps his beard well kept and thick, attempting to hide some facial scarring from a skin graft on both of his cheeks and neck. He dyed his hair a dark forest green colour, and has kept with it ever since.

A forced introvert, Jace doesn't get comfortable with people easily, and is usually reserved in a large group of people, trying to blend in. Some people can break him out of his shell and he'll take charge, but it is seldom and requires him to have the confidence to do so.
