"BTW, the Temple of Trials was built on the ruins of an older Pre-War building, most likely a church. The carved head at the entrance and some of the carvings/wall decorations on the three sub-levels were done by the Arroyo inhabitants." - Fallout Bible 5
"The entire Temple of Trials thing is one big mystery and is pretty implausible - the sliding
mechanical doors are what really confuse me. I think it came down to an art decision.
Anyway, the story I'm sticking to in the official universe is that the Temple of Trials is actually built on an
existing abandoned church - or museum." - Fallout Bible 8
You got me there.
As for why the Vault 13ers and Arroyo residents can't return to Vault 13? The Chosen One sold Vault 13 to NCR for (at most) $20,000. The mechanics of legal ownership questions in the Wasteland aside, once you've given the location of an empty, undefended Vault full of functional pre-War goodies to a strong expansionary power, you can't expect to come back to the place and see it in the same condition you left it. If I were Tandi and NCR, I'd have sent a pile of guards and a team to strip it down to the bone ASAP.
