Heart of Lorkhan The Heart of Lorkhan , sometimes called his " divine spark , " was an Aedric artifact hidden beneath Red Mountain during the Dawn Era . Its most prominent appearance was during . The Heart of Lorkhan is known to be the Tower Stone of the Red Mountain . History . Dawn Era . Following the creation of Nirn , Lorkhan ' s heart was taken from him as a punishment for his creating the mortal plane . Not all myths state this is a punishment . Several Aedra tried to destroy the heart , but could not , so it was cast down into the depths of Nirn , never meant to be found . It landed in Resdayn , forming a large volcano that would come to be known as Red Mountain . First Era . Sometime in the First Era , the Dwemer discovered the heart while excavating under Red Mountain . Kagrenac , the Chief Tonal Architect and High Priest of the Dwemer began to experiment with the Heart . He created three tools : Keening , Sunder and Wraithguard to work with the heart . He would soon order the construction of the Numidium , a massive mechanical golem . He hoped to use the Heart as a power source for extracting the divine power from the Heart and in the experiments for improving the Dwemer race . This plan was interrupted by the arrival of Indoril Nerevar , his generals ( Vivec , Almalexia , Sotha Sil , and Voryn Dagoth ) , and an army of Chimer . Nerevar and Dagoth fought the Dwemer king and Kagrenac in the heart chamber beneath Red Mountain . When the Dwemer were bested in combat , Kagrenac used the tools on the heart , and the entire Dwemer race vanished . Another account stated that King Wulfharth was resurrected as Shor ' s avatar and amassed an army comprising of Nord s , orc s , and House Dagoth to obtain the Heart of Lorkhan , which to the Nords was considered the Heart of Shor . In the climactic battle at the Battle of Red Mountain , Wulfharth had obtained the Heart but needed time to acclimate to its power . During this time , he and Voryn Dagoth faced Nerevar and his two companions , Alandro Sul and Dumac Dwarfking . Wulfharth blinded Alandro Sul with a shout and slew Dumac , but was weakened by a blow from Dumac ' s warhammer , Sunder . Neravar took the opportunity to finish Wulfharth off and slay him with a surprise side attack with Keening . With Keening , Nerevar cut out Wulfharth ' s heart . Nerevar entrusted the tools to Voryn Dagoth ( who had requested that the tools be destroyed ) and met with his other generals . They agreed to keep the tools but to not use them . In some accounts of this event , Nerevar then dies of his wounds from the battle with the Dwemer . Upon returning to the heart chamber , those who return discover that Voryn Dagoth had gone mad and refused to relinquish the tools , stating the Nerevar had commanded him to keep them from falling into the wrong hands . In the ensuing battle ( by some accounts involving Nerevar ) , Dagoth was driven away , forced to surrender the artifacts . This turn of events concerned Nerevar and he decided to ask the Daedric Prince Azura for guidance . However , his generals murdered him during the ritual . Azura still came and cursed the Tribunal for their crimes , claiming that she would use her powers to resurrect Nerevar . She then changed the Chimer into the Dunmer . Then the Tribunal used the Tools on the heart and became living gods ; they did many great deeds for their people . Since their deeds worked against the evil nature of the heart , they needed to return to it from time to time to rejuvenate their powers . At some later point , they discovered that Voryn Dagoth ( now styling himself as Dagoth Ur ) yet lived and had connected himself directly to the heart ' s power . He drove them away , and on subsequent attempts to recover the heart chamber for themselves , they lost control of Keening and Sunder to him and barely escaped alive , supposedly due to the quick actions of Vivec . Over time , the Tribunal became weaker and weaker , whilst Dagoth Ur became stronger still . They disappeared from public view , and their influence faded . Their sole attempt at restraining Dagoth Ur ( the Ghostfence ) consumed much of their remaining power and was largely ineffective at containing the Blight . They also could not prevent Dagoth Ur ' s forces from flying or tunneling past the Ghostfence . Third Era . Towards the end of the Third Era , the Nerevarine came face to face with his old ally and broke him . However , while sustained by the heart , Dagoth Ur could not truly die . By using the tools Sunder and Keening on the heart again , without a proper ritual , the Nerevarine destroyed the heart , and was able to deliver a final death blow to Dagoth Ur and destroy his great weapon , Akulakhan . Fourth Era . The Heart is briefly mentioned during the quest " Discerning the Transmundane . " When Septimus Signus discovers a Dwemer Lockbox brought in by the sudden flood in Winterhold , he believes the Lockbox contains the Heart of Lorkhan . The Dragonborn found an Elder Scroll and inscribed the encryption into a Lexicon . The Elder Scroll and its knowledge was apparently held in Alftand . The quest may only be started by meeting Septimus Signus at his outpost north of the College of Winterhold . Upon completion of the quest the Dragonborn and Septimus Signus discovered the Lockbox does not contain the Heart but instead the Oghma Infinium . The Heart was also mentioned as being requested by Wylandriah in her letter to the College of Winterhold . Although the College did not possess the Heart , experimentation similar to that of Kagrenac was indeed going on in the College , performed by Arniel Gane . However , Arniel was only using an approximate model of the Heart made from a soul gem . On Solstheim , there were stones of unknown origin known as Heart Stones that appeared after the eruption of Red Mountain , suggesting they may be somehow related to the Heart . Quests . The Citadels of the Sixth House . Using Keening and Sunder while Wraithguard is equipped , attack the heart until it loses its power . Discerning the Transmundane . Septimus Signus believes the heart to be located inside the Dwemer contraption within his outpost .
