Battle of Red Mountain The First Battle of Red Mountain was a battle between the Nord s and an alliance of Dwemer and Chimer at Red Mountain during the First Era conflict known as the War of Succession , at around 1E 416 . During the War of Succession , the Nords became weakened by their internecine conflict . Seeing an opportunity for freedom , the Chimer under Indoril Nerevar and the Dwemer under Dumac forged an alliance between them to combat the Nords . The Dwemer and Chimer attacked the Nords at Red Mountain , driving them from the land with " great slaughter . " Jurgen Windcaller and his fellow Tongues , according to Emblem VII of High Hrothgar , " went away humbled , " although it led him to believe that the gods were punishing the Nords for their arrogant and blasphemous misuse of the Thu ' um . The battle was a considerable setback for the Nords and was one of the factors leading to the end of the First Empire of the Nords . There was another " Battle of Red Mountain " around 1E 700 , and was the climactic battle involving the Heart of Lorkhan . One account stated the war was solely between the Chimer and the Dwemer . This account states that the uneasy truce between the Chimer and Dwemer evaporated during the War of the First Council . Several accounts attribute the war to simple cultural differences between the Dwemer and the Chimer that were too great to allow for peace . The event that began the march to war was the discovery by House Dagoth that the Dwemer had discovered the Heart of Lorkhan beneath Red Mountain . This led to heated negotiations between Nerevar and Dumac Dwarfking . Upon being told by Azura that the Dwemer were building a new god under the mountain , Nerevar and the Tribunal issued an ultimatum to the Dwemer to stop work on their new god , or face destruction . Dumac , ignorant of the work Kagrenac had done on the Heart , refused . And so the Chimer and Dwemer went to war . Another account states that Wulfharth was also involved in this war and led an army of orc s , Nord s , and members of House Dagoth in this second Battle of Red Mountain against the Chimer and the Dwemer . According to the tales , the Nords had made plans to conquer their old lost territories for years but never followed through because they lacked a strong leader to lead them . Allegedly , that changed when Wulfharth was resurrected as Shor ' s avatar and united the sons of Skyrim to invade Morrowind and reclaim the Heart of Lorkhan . The initial battles for the Nords were devastating after making landfall . Although they thought the Dwemer and Chimer armies would be weaker with reports of them warring with each other , they were surprised to be beset by both armies . Some tales claimed Voryn Dagoth deceived Wulfharth and the Nords into believing he was an ally , and betrayed the sons of Skyrim by leading them into a combined Dwemer - Chimer ambush . Other tales claimed that some of Wulfharth ' s Nords deserted him when he allied himself with their traditional enemies and fell in the climactic battle with the combined Dwemer - Chimer army . Ultimately , Wulfharth died at the Battle of Red Mountain in 1E 700 , either by being weakened by Dumac and slained by Indoril Nerevar , or blasted away into ashes by Vivec . All accounts note that the war culminated in the Battle of Red Mountain . All available sources agree , however , that the Dwemer disappeared during the battle . This is either because Kagrenac turned his Tools on the heart , or because Azura told Nerevar and the Tribunal how to use the tools to banish the Dwemer . House Dagoth was also destroyed either in this battle or in its immediate aftermath . The Tribunal wrested Kagrenac ' s Tools and the Heart of Lorkhan from Voryn Dagoth and used them to give themselves divine powers . Unbeknownst to them , Voryn Dagoth did not die from their conflict but had secretly connected himself to the Heart long ago , turning into Dagoth Ur and becoming a divine being himself .
