This is the Cathedral of the Children of the Cathedral. I don't know why they say Cathedral twice.”— A teenager
To the outside world, the Cathedral is nothing more than an innocent (albeit intimidating) set up for the Children of the Cathedral organization, which tries to bring love and peace to the wastes. Below it, however, lies a secret underground Vault (more specifically, the Los Angeles Vault), which serves as a home and base for the Master.
The Cathedral can be found one square west and nineteen squares south of Vault 13.
The Cathedral was built some time after 2155, following the Master's discovery of the Boneyard Vault. He conquered the inhabitants and set up operations there, and the human cultists began to use the Vault as their powerbase. Eventually, this monumental building known as the Cathedral was constructed above the Vault. The Cultists thus became known as the Children of the Cathedral.
Most of the Cathedral ground was taken up by the massive main chapel, whose vaulted ceiling was lost in the darkness above. Small chambers flanking the entrance to it were usually taken up by chanters or other devotees, while doors from the chapel itself led into the Cathedral's infirmary (headed by the notorious Dr. Wu), the shop, offering various souvenirs for the discerning pilgrim, the buildings main power generator, High Elder Lasher's chambers, the base of the tower as well as access to the basement, which, officially used merely as a storage space, also hid the entrance to the Los Angeles Vault.
From time to time, Father Morpheus would come down from his chambers to give a speech to the gathered faithful. Sometimes, even a giant holographic image of the Master appeared, to the awe of the assembled.
The adjoining tower had three floors, where the nightkin resided, as well as the more important members of the Children of the Cathedral, like high priests. Dane resided in a room on the first floor of the tower, while Morpheus, the leader of the Children, resided on the third, upper floor.
- In the Fallout: New Vegas add-on Dead Money, Dog may sometimes say to himself: "I want to go back, back to the base. Or the Church. Liked the Church." As Dog was once a soldier of the Master, "the Church" is a reference to the Cathedral.
- The log of Richard Grey found on the Vats control computer at Mariposa Military Base reveals that the Master chose to leave the base in order to find an ideal permanent location for his future operations, to avoid the disadvantages of a 'mobile body'. It is not known how he managed to get to the Cathedral, as he was a horribly mutated, and probably immobile, blob of flesh.
