Vyalldehun was a powerful, ancient ice linnorm who lived in the dungeons below the Ice Spire in the northern Thanelands of the Lands of the Linnorm Kings. He died over three centuries ago, but many of the dungeon's inhabitants still are associated with it. The nearby Vyalldehun River, located just north of the Ice Spire, is named after the linnorm.
