Who is Cecil de Morgan from Time's Eye and what is their importance?

Attracted to the fringe of civilization, Cecil is disapproved of by his officers, but maintains his popularity by supplying the men with beer, tobacco and even prostitutes. He also supplies occasional bags of Hashish for the officers, including Ruddy. Close to thirty years old, he is tall in stature but small in mind. Cecil is a fair weather man who serves whatever master seems to be to his best advantage. He has no difficulty reporting his friend's conversations in an effort to gain favor with the newest regime, and quickly earns the distrust and disgust of his fellow travelers.
