Skyrim:Fahlbtharz

It is inhabited by rieklings settled outside near the entrance and inside along the entry hallway, as well as albino spiders, oil spiders, and Dwarven automatons found deeper down. It contains four interior zones: Fahlbtharz, Fahlbtharz Corridor, Fahlbtharz Boilery, and Fahlbtharz Grand Hall.

Walkthrough
Exterior
You will be ambushed by three rieklings near the entrance, one of which will be mounted on a bristleback. The Dwarven structures are partially destroyed and situated on a slope. There are also a few riekling structures, comprising a hut and a bridge leading to a Dwemer tower with a chest and a copy of the rare book ''Nchunak's Fire and Faith beside it.

Fahlbtharz
Due to its placement on a hill, the entry hallway is tilted. Go straight ahead and face a couple rieklings inhabiting this area. There is a fire behind some fencing with two pieces of charred skeever meat on top, and in and beside a tent opposite are three books, including a copy of Where were you when the Dragon Broke?. The hallway to the west then descends to the south and west, passing another tent and two more huts. Proceed south through several broken pipes and piles of rubble until you reach an open door and two dead rieklings pierced with Dwarven arrows. Avoid the two pressure plates that activate the slicer trap just before the door, and head inside.

Follow the passage to fight a leveled Dwarven sphere, then enter a room with a 10-button control panel on the right and a novice-locked door with a Dwarven chest behind it on the left. The buttons, numbered from left to right and top to bottom, trigger the following:

To progress, activate the second button from the right in the bottom row (9). The gate that has now been opened leads to a hallway with a caved-in room on the left containing an adept-locked chest. At the end of the hallway is a room containing a kinetic resonator, with an expert-locked chest on the wall to the left. Hit the resonator to open the nearby gate to the east, and make your way through a web-covered section of the dungeon housing several oil spiders, also passing several albino spider eggs and several different fungi. Eventually you will reach a closed gate, which can be opened by hitting the resonator hidden behind the destructible spider web to the left of the gate. Beyond the gate, downstairs, is a room with a mushroom garden containing three white cap, two blisterwort, two imp stool, two bleeding crown, and a fly amanita fungi. You will need to deal with two Dwarven spiders and a sphere in the two adjacent rooms. The first room through the doorway beside the mushroom farm is a bedroom containing four stone beds around a central table, with an unlocked Dwemer chest near the east wall. Enter the room to the west with a pile of rubble in the center that has broken another table in half, and go through the door at the end of the hall to the left.

You will end up in an expansive chamber full of tall pillars, bearing platforms and walkways at their higher levels, and many giant spinning gears on the lower levels shortly above a large pool of water. Three Dwarven ballistae will be guarding the higher levels. Jump down onto one of the spinning gears from under the small Dwemer tower to your right. Navigate southwest over the gears, some of which hide Dwarven spiders, and you will find the entrance to Fahlbtharz Corridor.

Fahlbtharz Corridor
There are two pressure plates near the entrance that trigger a ballista. On the way upstairs, there is a pressure plate connected to a slicer trap. A single Dwarven sphere will be spawned if you activate any of these three pressure plates. Upstairs to the left is an adept-locked gate, behind which are various Dwemer items including seven pieces of smeltable scrap metal and a war axe, and a chest. To the right is a door leading to a higher level of the main chamber, back to the zone Fahlbtharz''.

Back in the main zone, turn left and go upstairs, and you will find yourself in a small alcove with a valve and a lever. The valve lowers the bridge in front of you leading to the water level of the chamber. Pulling the lever will rotate the nearby tower and extend a bridge to it. Cross the bridge and proceed straight ahead as far you can, then jump down onto the spinning gears. One of the gears has two large coin purses and a random enchanted shield in the center. Cross the gears and jump onto the platform ahead. Go upstairs, where you will find the corpse of Eydis, an explorer presumably killed by Dwarven automatons. You can loot her body for a set of Skaal armor (excluding the hat) and her journal. There is a door on the left leading to Fahlbtharz Boilery, and a valve ahead which lowers two ramps down to the water level of the chamber.

Fahlbtharz Boilery
As you enter, you will notice there is an inaccessible gate to your right and a kinetic resonator behind it. Past the gate, fight a Dwarven spider on your way downstairs to find yourself in a long room full of vent pipes and gears. There will be a shelf ahead with a Dwarven bow and four quivers, each containing 12 Dwarven arrows. A single Dwarven ballista stands guard at the end of the room.
 
Your progress will be blocked by a closed gate controlled by a steam-powered Dwarven mechanism. Get on the platform above, either by riding the two pistons up at this end, or by walking to the far end and climbing the stairs. There is a small alcove underneath the upper platform containing a table and chairs along with four unlocked Dwemer chests. In the center of the upper platform above the alcove lies the corpse of another unlucky explorer, Ulyn, which can be looted for his journal providing a few hints on how to solve the puzzle. Nearby rests a leveled enchanted bow and a quiver of 25 random arrows of up to ebony quality. You will also see a boiler consisting of a large Dwemer gear with twenty steam meters around it, and six resonators: three to the left, and three to the right. Each resonator represents a value (see puzzle values), which equals the number of steam meters that will be powered when that resonator is hit, or the number that will be reset when the resonator is hit again. Steam meters are powered progressively and clockwise, whereby each steam meter glows blue when powered, and orange when overpowered.

Puzzle Values
Values of #1 and #6 are hinted in Ulyn's journal.


The puzzle is solved when all twenty steam meters are powered, and none are overpowered. This can be achieved by shooting resonators #1, #2, and #5, numbered 1-6 from left to right as you face them. However, if the resonators are hit incorrectly, the boiler will be overcharged, venting out steam and spawning hostile Dwarven automatons. Failing more than twice will result in three moving spinning blades being activated instead.

Go upstairs through the gate that has been opened, and you will find the resonator that opens the previously inaccessible nearby gate. Destroy the nearby spider, then open the door straight ahead leading to a higher level of the main chamber, back to the zone Fahlbtharz.

Back in the main zone, an essential lever that is easily overlooked will be on a wall directly to the right. The walkways will then align in a way which, after some further gear-navigating and resonator manipulation, will lead to Fahlbtharz Grand Hall. A lootable skeleton with a random enchanted bow and a quiver containing 15 arrows of leveled quality nearby can be found in the tower with the resonator. The opposite tower holds a large Dwarven chest. To the left of the entrance to the Grand Hall, on top of a nearby tall rock formation below, is a lootable skeleton holding a small expert-locked Dwarven chest, as well as an apothecary's satchel with three lockpicks next to it.

Fahlbtharz Grand Hall
You will find that the entire hall is covered with spider webs, so prepare to fight several albino and oil spiders. Two Dwarven Centurion Guardians can be found sleeping in the corners ahead, but will not awaken unless attacked or otherwise interacted with. As you move away from the entrance, two Dwarven ballistae will ambush you from above.

Within the hall is a round platform with three Dynamo Actuators that must be filled by Centurion dynamo cores, dropped by the Centurions nearby, to progress. Fortunately, the middle actuator is already filled. The actuators, from left to right as you face them, trigger the final gate, the staircase to it, and the bars before the gate, respectively.

After filling the Dynamo Actuators, you will be able to access the treasure room, which contains five piles of gold, a treasure chest, a leveled battleaxe up to Daedric quality, a single Kagrumez Resonance Gem, and the unique Dwarven helmet Visage of Mzund. Activate the lever on the left to lift yourself back to surface, directly north of the Abandoned Lodge. This means leaving three valuable centurion dynamo cores behind; the alternative is to take them and make the long trek back to the surface the way you came.

Notes
Moving across the spinning gears and into the nearby towers can be frustrating. A carefully targeted Whirlwind Sprint can sometimes get you where you want to go; save the game before trying.
It is possible to get into the treasure room and retain two dynamo cores by removing the center one that controls the stairs, then placing it in the activator that opens the swinging gates. Once you have that set, jump onto the right activator that controls the bars, place a core into it, then remove it and quickly use Whirlwind Sprint as you line your sight with the opening to the control room. It is very tight timing, but it can be done. Note: Your follower will catch up to you when you leave the room.
It is possible to loot some items from the treasure room without any extra dynamo cores by using Telekinesis to pull items through the bars.
