Dagoth - Ur ( Quest ) Dagoth - Ur is the ninth main quest of . In this quest , the Champion finds the eighth and final piece of the Staff of Chaos . Walkthrough . Dagoth - Ur . Recommended effects : Dagoth - Ur is the volcano located on the center of the island of Vvardenfell . Common features includes much lava — more than any other dungeon in the Main Quest — and some of the most powerful creatures encountered in , such as Liches and Vampires , but also Stone Golem s , Wraith s , Ghosts , Hell Hound s , and Homonculi . The Final Piece of the Staff of Chaos remains inside the corridors of this dungeon . First Level . The First Level is a large zone with confusing passageways , but fortunately the door to the Second Level is not far away from the entrance . The fastest way to reach the next zone is to go west immediately after entering the dungeon , fighting with Hell Hounds , Homonculi , and Wraiths . The door to the Second Level is locked , and the Mithril Key which opens it is guarded by a Vampire inside the room close to the door , in the northwest zone . The room is also locked , but it is possible to open it using an unlocking spell or simply attacking it . It is important to remember that Vampires are the second strongest creature encountered , having power to deal massive damage with his sword or with Fireballs . After defeating the Vampire , the Mithril Key can be looted from his corpse and used to open the Second Level ' s entrance . Second Level . The Second Level is also a large area , however this time the Eternal Champion will have to explore all of it . The entrance to the Third Level is protected by five doors , each one has a corresponding key located in different zones of the Second Level , they are the Ruby Key , the Sapphire Key , the Crystal Key , the Amethyst Key and the Diamond Key . However , if the Eternal Champion has the effect Passwall , either by spell or enchantment , they can break the walls and open only the last door with the Diamond Key , which is found close to the center of the Second Level and is protected by a Lich near an abyss ( " see map " ) . The Ruby Key is above a platform surrounded by lava inside a large room located in the northwest zone . An Iron Golem will be protecting this key . The Sapphire Key is also located above a platform surrounded by lava protected by a Fire Daemon , this time in the northeast zone of the map . This location can be only reached through a hidden passage or by using Passwall . The Amethyst Key is also above a platform in the southeast zone , guarded by a Vampire , however this one is surrounded by an abyss . As mentioned previously , the Diamond Key is protected by a Lich near the center of the Second Level , and the Crystal Key is located on a room in the southwest with only one entrance , surrounded by lava . To take this key , the Eternal Champion will have to carefully jump over the lava . The key is protected by a Medusa . ( " all these five keys are represented in the map with white markers " ) . If the Eternal Champion uses Passwall to break the way , before doing the next step , it is very recommendable to save the game and not to save again on the same slot until getting out of Dagoth - Ur . This is a measure of safety to ensure the Champion will not be locked inside the Second Level . When the five keys have been obtained , the Eternal Champion must open the doors . After opening the last door , Stone Golems will be protecting the entrance to the Third Level . When they are defeated , the Eternal Champion can enter the last area of Dagoth - Ur , the heart of the volcano . Third Level . This level is different from the other two — it is simply composed by one corridor and a large lava lake . The Final Piece stands right in the heart of Dagoth - Ur , surrounded by lava . To reach it , the Eternal Champion must first go through a corridor guarded by Homonculi and Wraiths . The heart of Dagoth - Ur is the last area of the dungeon and one of the most dangerous places in . Four Fire Daemons guard the corners of this zone , and three Liches can be encountered next to the walls . Ghosts and Homonculi are seen flying above the platforms surrounded by lava , and more Homonculi are encountered above the central platform where the Final Piece stands . It is not necessary to fight the Liches nor the Daemons to reach the Final Piece , however defeating them will grant a great quantity of experience points to the Eternal Champion . If the Levitation effect is available , it should be used now to fly above the lava . If the effect is not available , the Eternal Champion will have to jump through the platforms and reach the central platform . The Final Piece is surrounded by walls and it is a bit difficult to come close to it . The Eternal Champion must stand right in the front of the flying blocks and jump above them ( " the Levitation effect must not be active ; the mouse can be used to adjust the character to the right position " ) . The Eternal Champion will fall inside an abyss and the Final Piece shall be in front of them ; they just need to climb up the wall and touch the Final Piece . It will give a riddle before being obtained : The answer is ( humorously ) " E . " The Final Piece will then join the pieces collected earlier and finally repair the Staff of Chaos , and the following message will appear to the Eternal Champion . The Eternal Champion must now exit Dagoth - Ur , breaking the way again if they used Passwall to skip the Second Level . The Staff of Chaos is finally completed , however , an unexpected problem is discovered . Ambush . For the last time , the usurper Jagar Tharn appears to the Eternal Champion and reveals that before splitting the pieces of the Staff of Chaos around Tamriel , he had drained its magical power . The Imperial Wizard will defy the Eternal Champion to travel to the Imperial Palace in the Imperial Province and meet him personally — if , of course , he survives Tharn ' s minions , who are sent again in a new ambush . After Tharn ' s creatures are defeated , the Eternal Champion must rest and receive Ria Silmane ' s new vision to start their final quest and finally save Emperor Uriel Septim VII .
