The Cave of the Abaddon is a location in the Divide in 2281.


The cavern may only be entered after detonating a warhead on a northern offshoot to the canyon east of the Sunstone Tower. After detonating the payload, it opens to a blown open wall to an apartment. After entering the Cave of the Abbadon, it become noticeably more dim and apparent that the ceiling of the cavern is lined with dozens of collapsed buildings. The cavern opens to the ground being the side of a building with a tunneler nesting site to the immediate north.

Through a passageway of sorts, the cave twists and turns often with several tunneler nest frequenting the area. The cave comes to an end with a shaft of light from the surface breaking through and highlighting an apartment complex. An Auto-Doc lies in the rubble near the apartments. By entering the apartments and going through the kitchen and living area, there is a door at the end that leads to the buried Boxwood Hotel.

Behind the scenes
