After arriving in Appalachia, the Brotherhood of Steel tried to make sense of the chaos engulfing the region.  With the discovery of the PACT and the detonation of a nuclear weapon at the Nuka Cola Plant, Knight Shin heads south to investigate the Whitespring, at the Overseer’s urging, leaving Fort Atlas vulnerable. Little do they know that a traitor has infiltrated their ranks…and war descends upon them. Major Stein begins to confront his own demons, deep within his subconscious, while Vinny Costas has plans for the future of the Blue Ridge Caravan. Red and Cherry continue their quest to free Antlers, Amanda and Cindy attempt to persuade Rose the RaiderBot to help their cause, while Jones and Abbie head back into the Mire. And the remnants of the New Enclave are reunited at Riverside Manor…with an eye towards the Whitespring, and a daring rescue attempt. The fate of Appalachia hangs in the balance.
