Fahlbtharz Fahlbtharz is a Dwemer Ruin located in the mountainous northern region of the island of Solstheim . It is one of three Dwemer ruins located on the island . Walkthrough . Following the path will lead to a room with a Dwarven Sphere . Ten buttons in two rows of five can be found there , with the following effects labeled from one to ten : Continuing the path leads to a platform entrance to a huge cavern with giant Dwemer gears spinning over a floor of water and high dwarven towers up ahead . Upon walking to the end of the right side of the platform , one can jump onto the gears . Some gears will have pipes in the center , where Dwarven Spiders will emerge . Continuing south leads the Dragonborn to the Corridor Room . Room of gears and Fahlbtharz boilery puzzle . Going to the left will bring the Dragonborn to a small room , with two doors and multiple buttons . Behind the first door is a chest on the wall , and some scrap metal . To open the other door , press the second button from the right on the bottom row . Go through the gate and down a corridor with a chest in a room to the left . Continue until reaching a Tonal Resonator . Hitting the resonator will open the gate to the left . Proceed though the webbed corridors and defeat several Oil Spiders . Eventually , the Dragonborn will end up in a room with a gate . Looking a bit left and back down the corridor is another resonator hidden behind some webbing . Hitting that resonator will open this gate . Continuing down the passage and through a door leads to a room with a planter filled with assorted fungi . Kill the several Animunculi here and pass through another door to the room of gears . When going straight and staying on the gears , the Dragonborn may get to the other side of the room . Passing through the gear mechanisms and going up the stairs leads to the body of a Nord adventurer named Eydis . Her journal explains she and her Dunmer companion , Ulyn , are searching for the Visage of Mzund . To find Ulyn ' s body , one must enter the Fahlbtharz boilery and go to the top floor of that room ; his journal explains the boiler mechanism . There are six valves that must be shot , and each fills a different amount of lights in the center . One must shoot the correct valves to equal twenty lights . If more are triggered , the lights on the boiler mechanism turn orange and Dwemer automatons will appear to attack . The valves hit will light the following number of lights : Use a bow and arrow and shoot the valves . The only solution to the puzzle is to shoot the far left , middle on the left , and middle on the right valves . One may also use a Destruction spell such as Incinerate or Icy Spear to shoot the valves . After going through the door that opens , one will find themselves back in the main cavern with the gears over water . There will be two leveled Dwarven Ballistas to eliminate . The second is over the bridge , and behind it is a chest with leveled loot . After defeating it , directly behind that across the bridge is a skeleton and a leveled bow . There is also another valve . To gain access to the Grand Hall , one must not hit it while standing on the same platform . Instead , one must go back to the rotating bridge and hit it with an arrow or magic . The bridge will then spin again , bringing the Dragonborn to the door to the Grand Hall . To the left of the bridge , before entering the Grand Hall , below , there is a small rock outcrop . On it , there is a skeleton and an Expert level chest . It contains leveled loot . It should be noted that if one chooses to jump down to retrieve the chest contents , they will have to go back through the halls to reach the Grand Hall Door again . It is possible to skip this whole process and go straight to the Grand Hall by using the Whirlwind Sprint shout and hopping along the edges of the bridges . The Grand Hall . Once entering the Grand Hall , there are a couple albino spiders , an oil spider , and two more Ballistas . After clearing those , there are two Centurion Masters . Killing them allows the retrieval of the Dynamo Core s to open the last door . To finish , one may simply grab the helm and the piles of gold around it . There is also one of the five Kagrumez Resonance Gem s on a plate . To exit , the lever must be pulled . Interestingly , the exit tower is not marked on the World Map , though other lifts , such as the Great Lift at Raldbthar , are . It is , however , marked on the Local Map as " Fahlbtharz Grand Hall . " The closest location to it that the Dragonborn is able to fast travel to , without going through the underground location of Fahlbtharz , is the Abandoned Lodge south of the Fahlbtharz Grand Hall exit lift . Alternatively , the Dragonborn can go back and grab all three Dynamo Cores , and retreat the way they came in , as the path is certainly easier going backwards than forwards and the cores are very valuable for crafting Daedric items at the Atronach Forge . If timed correctly , it is also possible to obtain two of the cores by taking the core from the pedestal which controls the stairs and then taking the one that controls the spike gate . Then , the Dragonborn must quickly use Whirlwind Sprint and they will be in the treasure room with both and the spike gate blocking the path back .
