When news had first reached Ajihad from Orthíad, Jörmundur was one of the five people summoned to be told Ajihad's plan (along with Arya, Orik, Eragon and Saphira). He was in command of Eragon and Orik's battalion during the Battle under Farthen Dûr, while Ajihad and Hrothgar lead the others. He was Ajihad's right hand man.
