While a peaceful group, they are persecuted by the Regulators, who both coerce them into doing their bidding and frame them for crimes against the people of Adytum. This makes it appear that the Adytowners are seriously threatened by the Blades; a convenient pretext for the Regulators' own repressive policies.
While relatively unarmed, a man named MacRae teaches the Blades his knowledge of combat skills as self-defense, and guards their front-door entrance from intruders. He is mainly the only 'representative' the Regulators parley with; however, there is little peace-talk. If the Vault Dweller agrees to help the Blades fight the Regulators, they will be instructed to go to the Gun Runners' fort and ask their leader for weapons and ammunition. After the Vault Dweller does what is asked, the Blades storm Adytum fully geared (the Vault Dweller may be in the fight as well if the player wishes).
Should the Blades become hostile, the player should be able to dispatch the entire contingent due to their poor armament and fighting skills (provided the player is properly leveled, armed and armored).
Appearances in games
The Blades appear only in the original Fallout, though a sign similar to the one from their hideout appears in Fallout 2 on a building in Klamath.
