Niduen was an elf and one of the few members of Arya's family left alive during the events of the Inheritance Cycle. She was of lower rank than Arya, but still an aristocrat. She was a famous weaver and sent Eragon a gift of Lámarae clothing upon his arrival in Du Weldenvarden. Bellaen du Hljödhr also mentioned her in the welcome letter they sent to Eragon.
