*You were the lone wanderer, sole protagonist of fallout 3s ingame world. You had cracked the code to give the wasteland access to pure clean water instead of irradiated poison. And you barely survived because the radiation was too much despite being outside the chamber.
It wasn't long before you heard about this courier 6, you were intrigued. It wasn't long before people were saying how the legion was beginning to get more violent despite the courier taking over the dam, basically making him in control of the mojave.
At this point it had been about 4 years since you'd left the Vault, but only 3 years since you did the mission that almost killed you.
At some point you had received post, it was a settlement in the mojave that wanted you to join forces with the courier. And it said the courier needed help but he wouldn't ask. So you decided to go to vegas.
Along the way you got stuck in a deathclaw hellground. It wasn't until someone came up and managed to draw their attention away you were able to move, but before you could an explosion went off killing them all. She looked over to see a man behind a shack, back against it with a sniper rifle. He was wearing an NCR trooper outfit that said 06. You'd found him. Only thing was he was with another guy, who was bald and also had ncr kit on. The courier then signalled you to go over, so you did.
"Look girl, I don't know who you are but being in the centre of a Deathclaw nest, that's next level batshit crazy."
Because of the mask you couldn't tell his facial expression, but he just seemed annoyed.
