Fildgor Orcthane Fildgor Orcthane , once known as Fildgor Strong - Prince , is a Nord prince born to Queen Mabjaarn Flame - Hair of Skyrim . He is Jorunn the Skald - King ' s exiled brother and leader of the famed Stormfist Brigade of western Skyrim . The Vestige encounters Fildgor with his Stormfist and Orsimer allies throughout Eastmarch as they try to usurp the throne from the current High King . He takes on the name Fildgor Orcthane and tries to disrupt the festivities of the Konunleikar in Windhelm , and is considered the region ' s primary antagonist . Background . Fildgor was the second son of Queen Mabjaarn , twins with Jorunn and younger brother of then Nurnhilde . While his brother studied the art of the skald at a young age , Fildgor who favored martial prowess explored the western lands of Skyrim to see its people where he met and befriended the Stormfist Clan . Although not of their own clan , eventually he became its leader and formed the Stormfist Brigade , where he and the Stormfists grew in reputation as brave adventurers . It was during Dir - Kamal ' s invasion of Skyrim that the Stormfist Brigade was put to the test . Fildgor and the Stormfists took back the beleaguered city from the Akaviri invaders , but not before the Queen and his older sister was killed . With the throne left vacant , Fildgor claimed the throne of Skyrim , only to be challenged by Jorunn who believed Fildgor ' s warlike intentions would bring ruin to Skyrim . To prevent a civil war , Jorunn challenged his brother to single combat , defeating Fildgor and exiling his brother from his lands . Since then , he has taken on the name Fildgor Orcthane , gathering the strength of his Stormfist allies and befriending Covenant and Orcish forces , waiting for a perfect time to strike against his brother . Interactions . Fildgor first makes his presence to the Vestige and his brother Jorunn during the Konunleikar celebrations in Windhelm . Sending a champion to represent the Stormfist Clan in the celebrations , the Stormfist Clan struck during the final contest at the Hall of Trials and charged at King Jorunn and his retinue . Fildgor then sent his troops to capture Fort Morvunskar . The Vestige arrives with reinforcements from Windhelm , only to find out that Fildgor was only after the remains of Nurnhilde . Fildgor is seen for the first time by the Vestige as he flees the fort , leaving behind his lieutenant Shukul gro - Agluk to deal with the Vestige . At Fort Amol , Fildgor sent his newly recruited Breton assassin and alchemist Dhalen to disrupt the King ' s council with the rest of the Pact members . Dhalen and his Covenant assassins assumed the faces of the royal guards through the use of an Argonian substance and infiltrated Jarl Ivanmar ' s manor . Planning to take on Jorunn ' s appearance , Dhalen was stopped by the Vestige and the Dunmer assassin Naryu Virian , but not before poisoning the king with Daedric poison . Jorunn manages to live with the help of the Dreamwalker and the Ternion Monks , while Fildgor retreats to Skuldafn . He plans to merge with Nurnhilde ' s spirit in Sovngarde , forcing the Crown of Freydis to recognize him . This would allow him to usurp Jorunn and become High King . However , Fildgor is stopped by the Vestige . Depending on the Vestige ' s choice , he can either be killed by the Vestige , killed by Jorunn , or spared and sent to prison .
