Scourge

The Scourge is the term often used by Pitt inhabitants to refer to the battle and mop-up operations conducted by the Brotherhood of Steel before their arrival in Washington, D.C. in 2255.

Background
On their way to the Capital Wasteland, the Brotherhood's forces came across the ruins of Pittsburgh, Pennsylvania. A truly chaotic city, it was full of rape gangs, raiders, slavers, and many other kinds of horrors all freely terrorizing the few innocent survivors.

Events
In a single night, the Brotherhood swept through the city from their staging area at Mount Wash, and eliminated any resident who put up a fight.

Aftermath
Lyons' contingent left the city with approximately 20 children in tow, who would later be initiated into the Brotherhood. Most were recruited into the Brotherhood. By 2277 only one remains stationed at the Citadel: Greg Bear, nicknamed Kodiak, stationed with Lyons' Pride.

During the Scourge, Lyons' forces suffered only one casualty: Paladin Ishmael Ashur, who was buried in rubble during the fighting and presumed dead. He survived and subsequently established firm control of The Pitt, transforming it into an industrial powerhouse, supported by Brotherhood technological know-how. Having fully abandoned the Brotherhood and its teachings, Ashur recognized the inherent failure of the unsustainable, scavenger nature of the faction's ways and moved forward in his own direction.

Residents such as Wernher recount how the area used to be much worse before the Brotherhood cleaned up the city, slaughtering half of the violent residents. He explains that due to the actions of the Brotherhood, the threats were sufficiently pacified or eliminated, allowing Ashur to exert control over the city to begin with.

Appearances
The Scourge is mentioned in the Fallout 3 add-on The Pitt.
