Denn Walc was a male Arcona from Cona. He was the son of Grand Nest Leader, Kimar Walc. When it was time for him to select a mate, he interviewed fellow female Arconans. When he finally selected a mate, he went up to her nest with a crowd. When she came out to greet him however, everyone gasped in horror. She had become a salt addict in the short time since he first saw her. She was unable to produce offspring.
