Callen is a green eyed blonde haired man who one might think has never cut his hair. He wears it braided in one single braid. Callen is a clean and a more sophisticated gentleman feeling very at home in any nobles court. His cares for everyone are genuine and hopes they feel the same for him. Though most of his time is spent in the libraries he enjoys these little outings as he gets a chance to let loose and enjoy life. His devotion to the Virtues and his efforts to follow the example of the Avatar are what has led the Resistance to identify him as a possible ally.
