The Mutual Aid Society prepared Planet No. 3 for settlement while North American factions maneuvered over the new world and their dwindling food supplies. Zhang Tianyuan discovered Snowpiercer Spacetime just as CW-7 triggered a rapidly worsening global freeze, leaving rescue workers staring at a tear in the sky.
The Mutual Aid Society revealed the scale of Snowpiercer Spacetime’s coming freeze, secured Cheng Wanli’s cooperation, and began preparing to stop Wilford’s train and free its hostages.
