Anhûin's clan was formerly the richest and oldest of the ancient dwarven clans before the Fall of the Dragon Riders. They lived in the Western portion of the Beor Mountains and volunteered their strongest warriors in Vrael's service. The clan was destroyed in Urû'baen by The Forsworn and Galbatorix. The surviving clan members were Anhûin and her guards. Anhûin died of grief and her guards took the name Az Sweldn rak Anhûin (The Tears of Anhûin). From her guards the clan has been restored to a portion of its former number and strength.
Anhûin's name is similar to the River Anduin in Tolkien's Lord of the Rings legendarium.
