Vault 101? Homage to 1984’s Room 101?

[Ciaphas Cain]

Maybe. Vault 101 like all the other vaults was secretly intended to study human behavior in drastic circumstances. Vault 101 was ostensibly meant to allow no one to enter or ever leave (though it's pretty obvious that some do).

There's a list somewhere of all the known vaults and the experiments going on within them. Among other things one vault had 99 women and one man, while another had 99 men and one woman.

There was also a vault that had one man and a crate filled with various puppets. And yet another that had a panther running loose inside it.
