Destruction of Raven Rock

The destruction of Raven Rock was the Capital Wasteland Brotherhood of Steel's obliteration of the Raven Rock Mountain Complex, the headquarters of the Enclave, committed by the Lone Wanderer on the Brotherhood's behalf in the year 2277.

Prelude
After the Capture of Project Purity, the Lone Wanderer discovered that Vault 87 held a G.E.C.K. Setting out to the Vault and retrieving it, the Enclave is revealed as having been tracking their every move, and incapacitated the Lone Wanderer with a concussion grenade. When the Lone Wanderer passed out, Colonel Autumn and his guard team transported the Lone Wanderer back to Raven Rock via Vertibird.

When the Lone Wanderer awoke, they were restrained in a photonic resonance chamber. Autumn began an interrogation. After refusing to give Autumn the code for the purifier, President Eden intervened just in time before the Lone Wanderer was shot and tortured. Autumn was ordered to report to Eden's office, and the Lone Wanderer was then left alone with Eden through an intercom.

With their restraints unlocked, the Lone Wanderer retrieved their belongings and went on their way. However, minutes later, Autumn ordered all personnel to ignore the president's previous directive and shoot the Lone Wanderer on sight through the base's intercommunication system.

Destruction
Fighting through waves of Enclave soldiers, the Lone Wanderer could have found Eden's self-destruct codes along the way. Upon reaching Eden's office, the Lone Wanderer spoke with Eden. Optionally faced with using the sequence, convincing Eden to end the Enclave or exploiting a loophole in Eden's internal logic system to put the base on self-destruct, the Lone Wanderer could have ensured the destruction of the entire complex.

After taking the vial of modified FEV, the Lone Wanderer departed the base following a final stand by heavier armed, fleeing soldiers waiting at the exit of Raven Rock.

Aftermath
The Enclave had no designated headquarters any longer, and with Colonel Autumn, the retreating personnel in Raven Rock flee back toward Project Purity.

Appearances
