While traveling outside Beartooth, they encounter a group of desperate geologists fleeing a nation unraveling under violence, division, and corruption. The recent passage of the Continuity in Crisis Bill—suspending elections in times of turmoil—has plunged America into a dark new era, pushing the country toward the brink of civil war.
