In the year 2254, some time after the destruction of the "west coast Enclave", the Brotherhood's ruling council, based in the Lost Hills bunker in Southern California, decided to send a contingent of soldiers all the way to the East Coast, with three important objectives. First, to scour the ruins of Washington D.C., once the nation’s capital, to recover any and all advanced technology.

I've done a bit of math. The difference between the time of the second expedition and Fallout 3 is 23 years. So far, so good. The time of this RP is 12 years [i]after[/i] Fallout 3. Combine that together for a total difference of [i]35 years[/i] between the second expedition and the start of this RP.
