Raven Rock, known as Site R before the Great War is the East Coast Enclave's main base of operations in the Capital Wasteland. It is also a former American military base and fallout shelter built before the Great War. It is the most northwest location in the Capital Wasteland.
About this creation
Raven Rock was designed at the beginning of the Cold War as a shelter for top military officials from the effects of a possible nuclear attack on the nation. The special ZAX unit, (later known as President John Henry Eden), was implanted in the site before the Great War to serve as a monitoring system for Raven Rock and tasked with coordinating communications between the many Enclave installations scattered across the country. Many decades after the Great War, ZAX began to observe the Enclave force in the Enclave Oil Rig and it gained knowledge with the extensive archives left in its early A.I. data base. Slowly ZAX modeled its own personality.
At some point after gaining self-awareness, John Henry Eden made contact with the Enclave leadership on the West Coast, establishing itself as a Presidential Adviser. Raven Rock came to serve as the central base of operations for the Capital Wasteland Enclave since the retreat of the Enclave force located in the Enclave Oil Rig in 2242, when John Henry Eden took control of the Enclave as the new President after the death of Dick Richardson.
Raven Rock is powered by a General Atomics nuclear reactor and gets its fresh water from deep underground wells and a mini purifier similar to other vaults. It is also likely that Raven Rock had manufacturing capabilities able to produce vertibirds, power armor, and weapons. The Satcom defensive array may also have been a part of Raven Rock's defense because the real world Site-R (Raven Rock) has a large number of satellite arrays. This combined with a significant defensive robotic army, probably made Raven Rock the second most powerful Enclave outpost (after the Enclave Oil Rig). After the Lone Wanderer was captured in 2277, a civil war breaks out in Raven Rock between President John Henry Eden's sentry bots and Colonel Augustus Autumn and the Enclave troopers. Raven Rock was eventually destroyed by the Lone Wanderer after their invasion, or by Liberty Prime during the two weeks after the activation of the Project Purity, if the Lone Wanderer didn't destroy Raven Rock before.
I could have sworn there was a MLDP (right way round?) Substation further Northwest than Raven Rock. There's a dart gun schematic up there, and I remember making the epic trek to get it. Ah, the good old days...Wait, I'm supposed to be reviewing the MOC, aren't I? Well, very good job!
