Who is Ludovic Seeley from The Emperor's Children and what is their importance?

Ludo is Australian, a journalist, and approximately the same age as Danielle, Marina, and Julius. He is very handsome, slender, and has a style of dealing with women that makes them feel a special intimacy. He can be very charming, but his life goal appears to be intent upon disturbing the way people view the world. His new magazine, The Monitor, will be his vehicle to create this revolution of thought. He casually courts Danielle until he meets Marina and marries her; however, the thrust of his conversations with Marina concern separating her from the teachings of her father. When Ludo's magazine becomes one of the victims of 9/11, he disappears from the novel and perhaps Marina's life.

Ludo sees himself as a sort of Napoleon, bringing clarity and revolution to the masses. Ironically, for someone who claims to bring clarity, he more often brings consternation with his disturbing remarks.
