The Cave of the Abaddon is a location in the Divide in the Fallout: New Vegas add-on Lonesome Road.


The cave consists of a long cave formed mainly by collapsed buildings. It is the only way to Ulysses' Temple, due to buildings collapsing in the Divide. The buried buildings, comprised of a stairwell and two rooms, serve as a transitional area linking the cave to the Boxwood Hotel roof.

Notable lootEdit

  • Eyebot upgrade circuit board - When facing the entrance of the cave from the clearing, detonate the nuke embedded in the rocks to the east. After the detonation, climb the beam on the ground marked with a blue old world symbol on it up to the blast site, and the circuit board will be on a destroyed eyebot lying directly ahead upon reaching the end of the beam.
  • Sunflower Summers' diary, for the Nostalgia challenge, is located in a suitcase near Summers' remains, along the northern wall of the first chamber of the cave.
  • A copy of D.C. Journal of Internal Medicine is located in the second room after entering the door to the Buried Buildings, between a toppled desk and chair, adjacent to a usable bed and a Ralphie poster.


  • It contains many tunnelers, including the tunneler queen.
  • An Auto-Doc is near the exit.
  • A swimming pool can be seen upside-down in the ceiling of the cave near the entrance.
  • A few seconds after entering the cave, the screen suddenly becomes much darker.

The Cave of the Abaddon appears only in the Fallout: New Vegas add-on Lonesome Road.

Behind the scenesEdit

"Abaddon" is an intensive form of the Hebrew word Abad, meaning "destruction." In the Biblical Book of Revelation, Abaddon is the name of a male angel seen in a vision as a king of an army of locusts. Considering the nature of The Divide, as well as its proximity to The Temple, this makes the cave's name a very fitting title.
