DO YOU KNOW HIM?

A man existed, he is a great warrior who calls for, sends to, fights but never involve himself during the war. He lives in a place where no one can see him and he is surrounded by soldiers, some in white and some in stained clothes. He is naked but can never be seen wholly. His powers are inestimable such that he can unlit fire but also behaves like a coward. Almost all adjectives can be used to qualify his way of life. Who is He and who are His warriors, the building surrounding Him?
