More on Goldmoon’s appearance, she never gets sick

Goldmoon sank deeper into her fur cape. She wore the soft doeskin breeches of her people with a fringed overskirt and belted tunic. Her boots were made of soft leather. Water had sloshed over the edge of the boat when Caramon had thrown Flint aboard. The water made the doeskin cling to her, and soon she was chilled and shivering.
“Take my cape,” Riverwind said in their language, starting to remove his bearskin cloak.
“No.” She shook her head. “You have been suffering from the fever. I never get sick, you know that.”
