Az Sweldn rak Anhûin, or The Tears of Anhûin, was a dwarf clan devoted to mourning the death of their former leader, Anhûin, and to avenge her by destroying all Dragon Riders, regardless of whether they served Galbatorix or the Varden. They were formerly led by Vermûnd.
Eragon encountered Az Sweldn rak Anhûin in Tarnag, on his way to Ellesméra. The clan, furious that Hrothgar had adopted Eragon into Dûrgrimst Ingeitum, declared themselves Eragon's blood enemies. Eragon's hosts, Grimstborith Ûndin and Grimstborith Gannel, protected Eragon for the duration of his stay.
In Tronjheim Edit
After the Battle of The Burning Plains, Eragon again encountered Az Sweldn rak Anhûin under Tronjheim. The clan sent seven assassins to kill Eragon and his four dwarven guards. Although outnumbered, Eragon and his guards fought bravely. They managed to kill all the assassins, losing Kvîstor, one of Eragon's guards, and sustaining minor injuries.
Orik proved to the other clans that Az Sweldn rak Anhûin had tried to kill Eragon using magicians, and traced each dagger the assassins held back to the dwarven city of Dalgon. The clan was banished from dwarven society until they replace their Grimstborith.
