Fort Defiance

Fort Defiance, formerly known as Allegheny Asylum, is a location in the Cranberry Bog region of Appalachia in 2102. It is located west of Watoga and east of the monorail elevator, on the edge of the boundary with the Savage Divide.

Background
Allegheny Asylum was originally built in the mid-1800s as a treatment facility for the mentally ill. It became a center of controversy for having its patients misdiagnosed and institutionalized without significant presence of mental health issues, and secretly marketing "Lunatic Tourism" for paid visitors. Family members of the patients were not allowed to visit without paying expensive fees. The Charleston Herald exposed the asylum's unethical practices, which led to its closing on March 17, 2061 and all patients being issued a notice of expulsion. However, only a few patients were collected by their families and many were left homeless.

Following the Great War, a group of survivors (led by Clara Duran) briefly occupied Allegheny Asylum until abandoning it after being threatened by other hostile survivors. Eventually the Appalachian chapter of the Brotherhood of Steel claimed the asylum and converted it into Fort Defiance, their main base of operations, and abandoning their prior base at Camp Venture in July 2093.

On August 19, 2095, Thunder Mountain Power Plant was lost. Without the power it provided, the Brotherhood's defenses stopped functioning and Fort Defiance was eventually overwhelmed by Scorched, marking the demise of the Brotherhood in Appalachia. With the Brotherhood facing unwinnable odds, they held their ground until the very end along with one last push into the glassed cavern to destroy the main scorchbeast nest in the Bog. Having no chain of command at the fort, along with no communication with Roger Maxson due to satellite failure, there was no backup and only their duty to the Brotherhood. In 2098, the Appalachia Brotherhood of Steel chapter came to an end.

Layout
Outside the entrance is an automated surface to air missile which must be defended during Line in the Sand. Fort Defiance's interior consists of four floors with the fourth one only accessible through an elevator protected by a laser grid which is unlocked by completing Recruitment Blues and obtaining a military ID card. The right wing is infested with feral ghouls and is mostly in disarray because the Brotherhood was never able to repair and clear out that section. A wendigo spawns in the room with the breaker panel.
