Raldbthar Raldbthar is an ancient Dwemer ruin in . It is located just east of Irkngthand . It is the location of Alain Dufont , whose death is an objective of the Dark Brotherhood quest , Mourning Never Comes . In addition , it is overrun by Bandits , Falmer , and Dwarven Automatons . At the end of the dungeon , the Dragonborn may exit to Skyrim or Blackreach . If the DLC is installed , this is also the location of one of the Aetherium Shard s for the quest Lost to the Ages . Sublocations . Raldbthar . The first room inside the ruins contains a flame trap blocking the way forward , with a charred skeever impaled by a pole that is set up so the flames will cook it . Damage can be minimized using Whirlwind Sprint or Become Ethereal to go through it without getting burned , or it is possible to go around the back ( right ) side of the post that is shooting fire . Straight ahead is an expert - locked gate with Alain Dufont and two other bandits behind it . With high enough Sneak and Lockpicking skills , the gate lock can be picked and Alain killed without too much trouble . The alternative is to proceed the long way around . At the flame trap , a hallway leads to the left . Down the hall is a large room with a single bandit towards the left ( northeast ) side . The right ( southwest ) end of the room contains two more bandits and a workbench . The path proceeds down a hall and to the right , where an open gate leads to the same room with Alain Dufont and two other bandits . Alternatively , straight ahead is a master - locked gate can be opened , and through it and to the right are two dwarven crossbow mechanisms aimed at the bandits that can be used by pulling the levers next to each one . After the bandits are dealt with , a gate underneath the crossbows leads to another large room with a bandit and many fallen rocks . The room contains more loot , mostly behind a locked gate . Through the next door and around a corner lies a Dwarven Sphere and then another door . The next large room contains loud gears , a spider worker , and two more Dwarven Spheres . The next door should be open , and leads to a hallway with a Dwarven Spider worker , and then stairs with a double blade trap , which should shut off automatically after the spider worker is defeated . Note that the blades tend to be very glitchy , so a save is recommended before going through the open door . If the blades don ' t stop after defeating the spider worker , they can be bypassed by getting next to the parts of wall where they can ' t reach , then once the blades are past , running to another part of the wall to get to the top . Next is a pusher / flame trap , and two more dwarven spheres . Up the stairs leads to a hallway with another workbench , a short set of stairs up , two spider workers , and , at the end , an elevator to the Raldbthar Deep Market . Raldbthar Deep Market . Down the corridor is a ramp down with another spinning blade trap . At the end is a door leading to steps down to a large room with many Falmer and two skeevers in a pen . On the far side is a set of stairs that lead up to a spiral ramp up to a platform with more Falmer . Another ramp leads down again to a button that drops a draw bridge from back at the previous platform . Back up the ramp , the draw bridge can now be followed up to another platform and another ramp down . From here , the rooftops can be crossed to gain access to a room behind dwarven metal grates . A hallway leads to a door , then to a set of steps down to a room with many pipes and escaping steam . Be careful of the floor trap at the top of the stairs , which trigger a ballista trap that can kill the player instantly . Within this room is a seemingly unaccessable chest on the floor above . There is a series of four large tubes slanting up and to the left . Using jump , the Dragonborn can climb up one of these slanted tubes . At the top , turn around and use whirlwind sprint to access a small ledge . Follow this ledge back toward the ballista trap location and you can access the chest . The next room possesses a large quantity of Dwemer scrap metal , four buttons and a blocked hall to the left . The first button will activate a fire trap , the third button will open the gate , and the other two do nothing . Through the door beyond the open gate is a room with a gate , a few leveled Falmer , and two Chaurus behind another gate to the left ( south ) that is novice locked . The Chaurus can be shot with an arrow through the opening to the left of the gate . There is a bridge with a button labeled " unpowered . " To lower the bridge , you must clear the large gears around the room of bones that are stuck in there . Clear the right hand gear at the entrance to the bridge pointing on it ( you will then see what is stuck in there ) and remove it . Clear a second gear on the left hand side of the room past the Falmer hut . Clear a third gear on the right hand side of the room . The final gear is underwater between the two stairs - hard to see . After all four blockages have been removed , head up the stairs to where the bridge will drop and press the button located on a small plinth to the left hand side of the platform . After unjamming all the gears , the button on the bridge can be pressed , which drops a draw bridge and activates a Dwarven centurion , though at higher levels , it may be a centurion master . Behind the centurion is a door that leads to a hallway with a lever at the other end that opens a gate . This room contains two Dwarven Spiders and a Dwarven Mechanism , which opens a set of stairs down to a door that leads to Blackreach . If is installed , the hallway to the right will contain an Aetherium Shard . The hallway to the left contains a lever which returns the player to Skyrim . Towards the exit to Blackreach on the right / left there is an expert door and master locked chest .
