This version of the Vault Dwellers are part of a wider crossover between multiple worlds.

Albert: "Another stranger from a different world... Seems like they're getting more common around here."

Natalia: "I trust nobody, especially not one from a place we've never seen."

Max: "Don't worry about that runt, Albert. I'll crush 'em!"

Albert: "Now now, no need to get violent Max. I think we can come to a more civil resolution." Albert turns to you. "My name is Albert. The girl is Natalia, and the big guy is Max. We've been exiled from Vault 13, so now we're trying to survive out here in the wastes."

Natalia: "Bastards kicked us out, even if we were just trying to help. And I have a sneaking suspicion the Overseer planned to kick us out anyway. They were looking for an excuse."

Max: "But we ain't so bad. We're just trying to make a new life out here. That is, until you otherworldly weirdos started popping up! So now we're trying to fix up this mess!"
