Beldaran was one of the daughters of Poledra and Belgarath. She was a gentle and affectionate person with blonde hair and a fair complexion. Unlike her twin sister Polgara she was not a sorcereress and therefore had a normal life-span. As a child, her mother came to her in a dream and told her that sorcery was not her path; that she was meant to "be" something, not do things. She was beloved to both her sister and her father, and when Belgarath chose her to wed Riva Iron-grip, her leaving the Vale of Aldur was a difficult time for both of them. Belgarath was tempted to send Polgara, but he knew he was meant to send Beldaran, as Polgara's white lock was a mark of sorcery.
In Castle of Wizardry, Polgara tells Ce'Nedra that Beldaran wants her to have her amulet, gifted to Ce'Nedra from Garion, made by Belgarath with the help of Aldur.
