A cryptic message was sent by the Brotherhood of Steel years ago talking about Defiance having fallen. The people in the area didn't know what the message meant. But I have a lead... someone named Abbie.
You must complete Coming to Fruition quest.
Abigayle Singh never had a chance to find the Brotherhood of Steel's headquarters... some place called Fort Defiance. But she did know the location of one of their bases: Camp Venture.
Go to Camp Venture and find the Letter to Tommy. The door / terminal to the main building is password-protected.
It's in the basement of one of the buildings.
Unlock orange doors with the Secure Storage Key and look inside for a note on a table called Command Center Password.
The Secure Storage Key is in the bunkhouse in a locker that can be picked (no skill required).
It turns out that the Brotherhood of Steel's Fort Defiance is actually located at the Allegheny Asylum, deep inside the Cranberry Bog.
Go to Fort Defiance and enter the building.
Try to open the metal door by pressing the red button.
I found Fort Defiance but the Brotherhood of Steel has security doors that are blocking it. And those doors need power.
Go to the top floor of the building and find the Circuit Breaker.
Now that the power is back on, I can get inside the Brotherhood of Steel's base. Maybe now I can find out what happened to them.
Return to the ground floor, go inside and read the Final Stand.
After completing this quest, you will be able to play the quests Recruitment Blues, Forbidden Knowledge.
