Felldir the Old is one of the three Nord heroes who stood against Alduin during the Dragon War in the Merethic Era. Where his comrades trusted their blades and the new Dragonrend shout, Felldir quietly packed a backup plan: an Elder Scroll. He wears a Greybeard’s robe and carries an ancient Nord greatsword.
Where to find them
You see him in the vision on the Throat of the World during Alduin’s Bane, and again in Sovngarde before the last battle.
Quests
In the vision he insists that Alduin cannot be killed like a lesser dragon, and reveals the Scroll. Hakon protests that they agreed not to use it, and Felldir coolly replies that he never did. After Gormlaith falls, he reads the Scroll and banishes Alduin. Without knowing it, he sent the World-Eater into the future rather than away forever, setting up the dragon crisis of 4E 201 and leaving a time wound on the summit.
In Sovngarde he is the tactician. He explains that Alduin’s mist is both shield and cloak and that four Voices together can blow it away. He then fights alongside you in Dragonslayer.
Services
Once Alduin is dead, Call of Valor can summon him as a temporary ally.
Personality & relationships
Felldir is the cautious, thoughtful one of the trio, the voice of grim realism next to Gormlaith’s bravado and Hakon’s thirst for revenge. In battle he backs up his words with Frost Breath. After the banishment, his reaction is not triumph but a hope that the spirits will forgive them. In Sovngarde he speaks of finally repaying the debt left by letting Alduin slip away.
Good to know
Despite reading an Elder Scroll, he shows no ill effects from it. He is voiced by Paul Eiding, who also voices Galmar Stone-Fist and Septimus Signus.
