Glassed Cavern

The glassed cavern is a location in the Cranberry Bog region of Appalachia in 2102.

Background
Ostensibly a minor quarry operated on the edge of the former Watoga National Park by Atomic Mining Services, the glassed cavern was actually an experimental site where AMS used atomic devices to try and create artificial ultracite. This also happens to be the first lair of the scorchbeasts, where Enclave forces acting on orders from Thomas Eckhart secreted away from the monstrosities, which were further twisted by their exposure to ultracite.

After the collapse of the Enclave due to infighting in 2086, following the decision to release the monsters, the Brotherhood of Steel tracked the monsters here during Operation Touchdown in 2095. Paladin Lizzy Taggerdy gave her life trying to contain the threat and succeeded in preventing them from attacking the surface for several weeks. Her body still remains deep inside the lair, alongside equipment from Enclave's and AMS' experiments, which according to the transmission on the last transponder next to her, left the Brotherhood in shock at discovering the scorchbeasts were man-made.

Layout
The glassed cavern is a former mining complex consisting of long underground passages. The tunnels are a long slog through hordes of Scorched. The entrance tunnel terminates in a cave-in that requires player characters to navigate through a side tunnel and two caverns containing AMS' maintenance equipment and the laboratory. This segues into the auto-miner maintenance point and a loading dock. The next stage leads to a curving cavern with a waterlogged shelter area and another small junction with a power armor frame. Along with the multiple Scorched that inhabit the mine, a scorchbeast is found near the exit elevator. Corpses of fog crawlers, cave crickets and mirelurk kings & queens litter the complex. There are also multiple scorchbeast bodies around the caverns along with the bodies of Brotherhood of Steel soldiers that killed them. The complex ends with a big cavern, where the body of Paladin Taggerdy, half-buried against the eastern wall, can be found and her final moments can be heard on a transmitter. There is a mine elevator in the back of the cavern that leads topside.
