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 can enter an underground section.

Layout
From what can be read from the terminals, the work site was extremely hazardous and a general lack of employee safety was apparent. Rumbles can be felt and heard throughout the mine, which can point to some supernatural force. This is owned and managed by the same company in DC at the Dunwich Building.

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

Watch your step when you come in, there is a tripwire trap not far from the entrance. As you enter, on the left there is a lift leading to a door. It requres a key, which is on a corpse on the other side of this door. You end up there if you go all through the facility.

If you continue 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 you have to turn left. There is a ladder leading to a Novice locked cell (tripwire trap at the bottom of the stairs). If you don't take the ladder, you'll 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. Ahead from the pit there's a door with chains on the player's side. It leads to a corridor with feral ghouls corpses (and not only corpses later on).

You end 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.

Notable loot

 * Kremvh's Tooth - 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 two mini nukes and the unique weapon. It is important to note that one should not dive into the pool with Power Armor on, as it will sink to the bottom and become impossible to recover.


 * If you have already obtained Kremvh's Tooth (as a random loot drop from a legendary enemy) before entering this location, it will be missing from it's original location in the underground pool.
 * Sneak bobblehead can be found on a small table near the section 4 terminal.
 * Astoundingly Awesome Tales (5% less damage from robots) can be found on an armor workbench near Bedlams Terminal in the giant pit room.
 * Mini nuke. 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. 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 alter containing the weapon.

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, you 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 realises 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." Perhaps more may be found in this area with the use of night-vision, power armor visions, or chems.https://en.wikipedia.org/wiki/The_Dunwich_Horror#Plot_summary
