Oh, come on now. Just look at that face. You know you love it. Anyway, I’m thinking about making a young lady who grew up in one of the experimental vaults, located in what used to be North Carolina. I still have to work out the details on how she got west, but I’ve got a few ideas. I’ll start on the sheet tomorrow, as its late here and I have to wake up at a decent hour. One question to any of you Fallout experts; Vaults, are they numbered based on location, or is it completely random?

I would guess based on location. Vaults on the west coast have low numbers, like 13 and 22, while vaults on the east coast have high numbers, like 101 and 87. Or rather they must have been built in order going east. Build number 1, move over, build number 2, etc.
