Who they are
The Brotherhood changes across games, but its core tension remains: it protects technology because technology destroyed the old world, yet its power can make it another force deciding who gets to use that technology.
Their story belongs to The Capital Wasteland and also touches The West Coast and The Commonwealth and Appalachia. A ruined capital where clean water becomes the first real chance at renewal.
Their story, step by step
- Step 1
Preserve dangerous knowledge
The Brotherhood begins from a belief that technology without responsibility destroyed the old world and must therefore be guarded.
- Step 2
Choose how to use power
Different chapters turn that principle toward isolation, humanitarian protection or military control, making the Brotherhood internally contested.
- Step 3
What their choices leave behind
Its story remains an argument over whether safety comes from withholding power or using it visibly on behalf of others.
Turning points
- Breaking with pre-war military command.
- Guarding technology as a moral duty.
- Repeatedly redefining its mission across regions.
Where their story stands now
Its story remains an argument over whether safety comes from withholding power or using it visibly on behalf of others.
