The year is 2228, somewhere in february, and somewhere in the East coast of the USA. you haven't really kept track of time. It's been around 151 years since the great war happened. That's atleast what your parents told you before they emerged from vault 13. And you just had to deal with some radroaches. And then, in the distance you see some girl with brown hair, killing a ghoul. And you approach her, her armour seems to be made out of tank armour. When she notices you she holds a pistol to your head.

Don't you dare get closer! Explain yourself! Who are you? She said anxiously, and a bit indecisive if she should even shoot you.
