According to Jorunn, they 'disagreed on who should succeed our sister. I believed in diplomacy and wisdom. Fildgor believed in rule by force. I couldn't let him take the throne. (...) I was forced to exile Fildgor. He never forgave me for that.' Jorunn requests the player to militarily support his legitimacy as the discontent Fildgor returns in another attempt to seize the kingship.
