From the very northwestern edge of this zone (the imposing Allegheny Asylum, now known as Fort Defiance), to the southeastern corner (the infamous and incredibly dangerous Glassed Cavern, where you uncover the final secrets), this is perhaps the most dangerous part of Appalachia: The threat level is the highest you’ll encounter, and you might very well end your days scrambling to exit the radioactive mess within the Flooded Trainyard or lose your footing and fall from a tall building within the city of Watoga (the landmark city within this zone). Indeed, Watoga is a place more dangerous than most, with robots and other high-level entities to battle. You also find evidence of the machinations of the AMS Corporation, and a maze of structures offer both vertical and horizontal exploration antics.
