Sleep & Consternation

A recent apocalypse has wiped out the majority of humanity. The remaining city, Rheaum, has built high walls around itself, allowing nature to reclaim the world. In order to avoid overpopulation and pollution, the government has split society into two halves- Cunae and Terrenen. One half of the society goes into hibernation for six months out of the year, alternating. When Cunae is awake, Terrenen sleeps, and vice versa. The people in these separate societies live comfortable lives. Until, of course, the 25th awakening, and the people of Terrenen are thrown into chaos.
