The note can be found in Fort Defiance, pinned to a bulletin just off the front entryway (cannot be taken).
Generators out of fuel. With all the Scorchbeasts, not sure how long the boys at Thunder Mountain can hold out. If the AAAs go down... we're all dead.
For anyone that reads this, know I tried my best. We all did. The Brotherhood of Steel held the line as long as we possibly could. But the Scorchbeasts keep on coming.
I'm running out of time. So please listen, if the Scorchbeasts are still a threat, you need to get to the top floor. The security doors are top of the line military security - find a way past them. Do what we failed to do. Stop the Scorchbeasts.
Power's flickering. Have to go. In the end, I get it. Ad victoriam.
