Belgabad was the largest and oldest dragon not bonded with a Rider who lived at the time of the Fall of the Dragon Riders. Glaedr called him "the greatest of us all". He was a distant ancestor of Raugmar the Black who was the great-great-great-grandsire of Saphira's mother, Vervada. In Inheritance when Eragon and Saphira visited Doru Areaba on Vroengard, Saphira says that she is proud to be of his blood. His skull alone was longer and taller than the main part of Saphira's body, while Eragon surmised his ribs to be at least 80 feet long and 15 feet wide at their thickest.
