It’s been almost a year since Vault 76 opened and the residents found themselves in an Appalachia none of them recognized. The Scorched have loomed large over everything in the region...even as the Vaulters struggled to begin rebuilding.

The New Enclave has risen at the Whitespring and spread its influence. But now, after Sunnytop, the Colonel realizes they are no longer alone, and the Scorched must be dealt with before these newcomers are exposed, infected, and carry the plague to the world.

We now learn the history of Operation Beowulf and set the stage for what is to come...a battle to decide whether Appalachia belonged to humanity or the monsters.
