Who is Norval Sanderson from Geek Love and what is their importance?

Norval Sanderson is an unscrupulous reporter who falls in love with the Fabulon after Arty has taken control, and the cult has been created. Initially, he covers Arty and the cult following, but finds himself falling under the spell of the entire act. He leaves his profession to become a maggot seller in the Fabulon, taking notes about Arty along the way. His notes and journals prove to be invaluable as they offer an unbiased report of what goes on during the Fabulon days, giving the reader more insight into the family from a perspective other than Oly's.
