Norn assists Dio and Mell through their journey as a guide, often giving them directions on where to go, as well as dictating the "Heroes of Eternity". She often whispers to the heroes in a mystical manner what portions of information they are allowed to tell Dio and Mell. She also allows them to explain the moral dilemmas during their journey in Tales of Phantasia, such as Cress Albane's emotional trauma from having slain Dhaos. Later, Norn protects the party from the ill-minded words of a masked man who relentlessly attempts to break the morale of the children, telling them not to listen to him because his words come only from hatred of life itself. She also protects them from various supernatural attackers, most notably, Dios and Meltia's illusional attacks in the Cave of Chaos.
