Dunwich Borers

The Dunwich Borers is a location in the Commonwealth in Fallout 4. It is home to a group of raiders in 2287. After clearing out the raiders that occupy the above ground portion of the quarry, the player character can enter an underground section.

Background
Before the war, it is presumed the site was owned by Dunwich Borers LLC, a company that manufactured rock drills for tunneling and drilling.

Initially, from what can be read from the terminals, the work site was extremely hazardous and a general lack of employee safety was apparent. However, as the Sole Survivor progresses further through the underground mine, a sinister operation is partially revealed.

Layout
The entrance is located all the way down the outdoor pit. The outside is guarded by about a dozen raiders, including one in power armor.

Watch the step when coming in, there is a tripwire trap not far from the entrance. Once entering, on the left there is a lift leading to a door. It requires a key, which is on a corpse on the other side of this door. The Sole Survivor ends up there if going all through the facility.

If continuing ahead from the entrance, there is a turret and several more raiders. A circuit breaker (a switch) turns the power and some of the spotlights off. Unlocked Station 1 terminal is next to it, on the right (can be used to turn off turrets). Watch out for the grenade trap near the terminal. Ahead from this there's a cooking station (near the turret).

Then the Sole Survivor has to turn left. There is a ladder leading to a Novice locked cell (tripwire trap at the bottom of the stairs). If the player character doesn't take the ladder, they will find terminal 2 ahead. Continue to terminal 3, near it there will be a huge pit with a mini-boss Bedlam down there.

In the pit there's an armor workbench with an issue of Astoundingly Awesome Tales (5% less damage from robots) on it. Also there's a Novice Bedlam's terminal with some notes along with a steamer trunk. Ahead from the pit there's a door with chains on the player character's side. It leads to a corridor with feral ghouls corpses (and not only corpses later on).

The Sole Survivor ends up near a wrecked machine with a skeleton. On the left there's a door, opening it triggers the first flashback.

There are more circuit breakers in the ghoul infested area, activating them turns on the lights and triggers some ghouls running towards the player character.

Notable loot

 * Kremvh's Tooth in an irradiated pool of water. After the first flashback head to the right to find section four. An irradiated pool is guarded by the four project managers, now feral ghouls, in a tunnel near the bottom of the pool is the unique weapon. If one dives into the pool with power armor on, it will sink to the bottom and become impossible to recover.
 * If Kremvh's Tooth has already been obtained (as a random loot drop from a legendary enemy) before entering this location, it will be missing from its original location in the underground pool.
 * Sneak bobblehead can be found on a small table near the section 4 terminal.
 * Astoundingly Awesome Tales #3 (5% less damage from robots) can be found on an armor workbench near Bedlam's Terminal in the giant pit room.
 * 3 Mini nukes. After passing terminal 3, descend the winding staircase after reaching the bottom walk straight forward and look up on the marble wall. There is a mini nuke sitting there, to the left of Bedlam's terminal up on the rock face. For reference there is an armor workbench off to the right of the stairs. There are also two Mini Nukes in the underwater pool with Kremvh's Tooth on the wood altar containing the weapon.
 * Bottlecap mine - located in the building at the top of the quarry. Sitting on the cabinet left of the turret control terminal.

Appearances
The Dunwich Borers only appears in Fallout 4.

Behind the scenes

 * Similar to the Dunwich Building in Fallout 3, random flashbacks to times before the Great War happen spontaneously, hinting to its paranormal background and its relations to the author H. P. Lovecraft, and his book series, the Cthulhu mythos, and particularly, the short story, "The Dunwich Horror". Note that in the bottom of the well in the end, one can notice part of a statue that resembles a face. Using Console commands it's possible to clip outside of the map to reveal the whole statue.
 * This can be interpreted as a reference to "The Shunned House", in which the narrator discovers the elbow of some titanic being entombed beneath the house and realizes that the rest of it must still be underground. The antagonist of the "Dunwich Horror" is an invisible monstrosity that can only be seen with "The use of a magic powder."
