Author Robert Jordan, whose "Wheel of Time" series of fantasy novels sold millions of copies, has died of a rare blood disease, his aide said Monday. He was 58. Jordan, whose real name was James Oliver Rigney Jr., died Sunday at the Medical University of South Carolina of complications from primary amyloidosis with cardiomyopathy, his personal assistant, Maria Simons, said. The disease attacks the body's major organs; in Jordan's case, it caused the walls of his heart to thicken.
