Who is Garm Bel Iblis from Dark Force Rising and what is their importance?

Garm Bel Iblis is an Old Republic Senator from Corellia. It was believed that Bel Iblis died at Anchoron. This assumption was incorrect in that Iblis merely lost his home, family, and friends..... he became a lone rebel, moving his base, "Peregrine's Nest," fourteen times in seven years.
